Chainsaw standard instruction manual. Working with a chainsaw: first start, safety precautions, video instruction. Stages of running in a new chainsaw

Before you buy a good chainsaw, you need to find as much information as possible about this tool and carefully study the principles of working with it. If you correctly, fully meet your requirements, and learn how to work with it, then working with a chainsaw will give you pleasure, while remaining completely safe.

Basic principles of work

If you have never worked with a chainsaw and have no experience with it, you need to understand the basic principles of working with this tool:

• hold the saw with both hands, clasping the handles with all fingers. At the same time, the thumb of the left hand should be under the front handle;
• during operation, it is impossible to stand directly behind the saw, it is advisable to be slightly to the side of the tool;
• you can cut both the lower and upper edge of the tool. If you cut with the bottom edge, the chain will drive the saw away from you, and if you cut with the top edge, the chain will move the saw towards you;
• when working with a chainsaw, try not to bend your back, instead it is better to bend your knees. When you work with a saw in a standing position, it is recommended to maintain balance with your feet wide apart;
• before moving to another place, you must activate the saw brake or turn off the engine of the tool. You can not move with a tool whose chain rotates;
• sawing should begin with the section of the tire closest to the tool body;
• in the event that you are going to work with a chainsaw often, it is necessary to purchase a set of protective clothing: a helmet with a mask, a bright protective jacket that is not breathable, special trousers with cut protection, strong gloves and durable boots, which should be protected if possible steel plates.

Currently on Russian market you can find a large number of chainsaws, which can be divided into three classes:

1. The first class includes simple household devices that are designed for simple household needs. Most often, such chainsaws have little power, but they cope with all their duties very well. With the help of such a chainsaw, you can cut down a rotten tree or prepare firewood for a bath. Despite the fact that the functionality of such saws is minimal, this is easily compensated by ergonomic controls and their low weight.
2. The second class includes the so-called semi-professional models that are capable of performing almost any work - from repair and construction tasks to felling trees. But at the same time, such models have one significant drawback - they are not designed to work 8-10 hours a day. It is for this reason that they are called semi-professional. Most often, lumberjacks use such saws as loppers.
3. The third class includes professional saws, which are great solution for people who specialize in deforestation. Such devices can be used for 10-15 hours a day, while allowing you to work without interruption for 8-10 hours.

Not everyone knows how to work with a chainsaw, so this question is of interest to everyone who has purchased this high-tech device. Some believe that they already understand everything and do not even look at the instructions. But such actions can lead in the future to either serious injury or damage to the chainsaw. Therefore, before starting work, do not be lazy and study the instructions well.

Preparation for work

First you need to make sure that the chain of the device is tensioned correctly, for which you need to slightly pull on the upper links - in this case, the shank should come out of the groove of the tire by a few millimeters. Also, you need to ensure that the lower links do not sag. After that, try to pull the chain with your hand - it should stretch easily. If the chain tension is very strong, then it should be loosened. Next, you need to check in what position the inertial brake is located - its handle and the main handle should not touch, since when you turn on the chainsaw with a displaced inertial brake, the clutch may be damaged.

After checking the chain tension, you can start refueling the tool. To do this, the chainsaw must be installed on a horizontal surface and pour chain oil and fuel mixture into it. The best option a fuel mixture of oil intended for two-stroke engines and A-92 or A-95 gasoline is considered. The ratio of gasoline and oil should be 1 to 40 or 1 to 50 (about 20-25 grams of oil per liter of gasoline).

For the motor and chain, you should choose a special lubricant designed for chainsaws, since such a lubricant contains components that can extend the life of the cutting element and engine parts. At the end of the test, after completing all the procedures described above, you can start the saw.

Remember that before starting the engine, it is necessary to remove the saw from the place where it was refueled so that a fire does not occur during starting. Place it on a stable solid base.

First start

After making sure that the chain does not come into contact with any surfaces, it is necessary to apply the chain brake by moving the brake handle away from you so that the chain does not start its rotation ahead of time. Since the engine is initially cold, it is necessary to fully extend the lever that controls the choke. Next, you should pass the toe of the foot into the rear handle, while holding the front handle with your hand, and pull the handle several times until the engine “sneezes”. Then it is necessary to transfer the air damper to the working position and start the saw by briefly pressing the throttle and turning the saw to idle. After that, you need to move the brake handle to the position on yourself and your chainsaw is ready to work.

Remember:

• before starting work, it is imperative to check the brake of the chainsaw, for which you need to install it on some flat surface and press the throttle. Next, you need to activate the brake by pressing the handle. The brake is considered to be working if the chain stops.
• among other things, before starting work, you need to check the lubrication mechanism. To do this, you need to find any bright surface, start the tool and, holding it over this surface, increase the speed of the chain by simply pressing the throttle. If a small strip of oil appears on the surface, then everything is in order with the lubrication mechanism.

The principle of sawing wood

Sawing with a chainsaw is necessary at full throttle. The cut should be made with a section of the tire located as close as possible to the body. Remember that for different materials you need to use your cutting methods.

Branch pruning

It is best to start cutting the trunk of a fallen tree from the branches from the bottom, while being on the left side of it. Work must be done at a calm, slow pace, trying not to use the nose of the saw. You can cut both the bottom and the top of the tire, if possible trying to lean the saw against the trunk or thigh. From the upper part of the trunk, branches must be cut with a tool lying on its side (with all its weight, the chainsaw should lie directly on the trunk itself). After cutting the branches that were on the side and on top, you can turn the trunk over and start cutting the branches that are below.

Remember:

• in some cases, the trunk of a fallen tree may rest on any one branch, cutting off which can provoke a shift in the trunk or even its rolling;
• if you come across a branch that is too thick, then you need to cut it in parts - starting from the end and moving towards the trunk. If the branch is particularly thick, then in this case it may be necessary to file the branch on both sides.

Crossing should be started only after all the branches have been cut from the trunk. It is necessary to cut the trunk of a fallen tree into parts from the trunk to the top.

Remember:

• during bucking, in no case should you stand below the trunk if it is located on an inclined plane;
• if suddenly the chainsaw gets stuck in the trunk, you need to stop the engine, and then tilt the trunk until the saw comes out of the wood. The saw should not be immediately removed from the tree.

felling trees

To begin with, before starting to cut down a tree, it is necessary to determine as accurately as possible where the tree trunk will be “more convenient” to fall. To do this, you should take into account how many branches are located on each side of it, as well as the direction of the wind and the natural slope of the trunk. You need to fell a tree in the direction where it is “more convenient” for it to fall. Before felling the tree directly, it is necessary to cut the lower branches so that they do not interfere with work. Currently, there are several different technologies for felling trees, which should be selected depending on many factors. Pick the right one wisely best way only a professional lumberjack is capable of felling.

Remember:

• if there are people nearby, then they should be at such a distance from the tree that is at least two lengths of the trunk of the tree that you are going to fell;
• before felling a tree, be sure that there is nothing nearby that could be damaged by its fall;
• felling trees is enough daunting task, therefore, if you do not have such experience, it is better not to take it on, but to entrust it to professionals. In extreme cases, you can ask them to be present during the felling.

Tool Care

Each time after the work of the chainsaw is completed, a number of steps should be taken to care for it:

1. First you need to check the lubrication of the chain and its tension. When the chain is loosened, it needs to be tightened, and if the oil runs out, just add it to the tank.
2. Let the saw cool down after all work is completed and after a short rest, refuel it.
3. You also need to check the condition of the air filter, as it can sometimes become clogged with chips. Therefore, at the end of the work, it must be removed, washed and blown. In addition, from time to time it is necessary to clean the surface that is around the cooling plates.

If you use a chainsaw very often, you will have to change some wear parts - parts of the anti-vibration system, drive sprocket, tire and chain, since not replacing a worn part in time can result in its negative impact on the overall condition of the tool.

When buying a chainsaw, remember that it is complex technical device requiring special skills and appropriate handling. Of course, everyone can learn how to operate a chainsaw in a short time, but do not forget about all possible precautions. Carry out a periodic inspection of the tool so that it does not completely fail from some little thing that you have not noticed.

If you carefully study all the information provided in this article, your chainsaw will work for a long time, and you will be able to avoid injuries and unpleasant moments associated with a broken saw.

Video instruction for working with a chainsaw

The chain saw has long taken its rightful place in the arsenal of almost every owner. personal plot. Not only professionals, but also amateurs prefer gasoline-powered tools, as they are more powerful and more mobile than electric counterparts. Almost every person knows or has seen how to work with a chainsaw, but, unfortunately, not everyone thinks about the fact that this work is preceded by the stage of mandatory preparation of the tool.

Basic moments preparatory work, are set out in this video instructions using the example of a two-stroke gasoline saw with a cutting depth of up to 50 cm, a 750 ml tank, designed for about an hour of active work.

• First, fill the reservoir with fuel mixture and, if necessary, lubricating oil.
• Check the operation of the power button and two levers on the saw.
• Extend the throttle lever before starting the engine.
• Move the chain brake handle slightly back, which is responsible for emergency stopping the chain in an emergency.
• Be sure to check the chain tension. Sagging is absolutely unacceptable. To correct the situation, loosen the two bolts on the saw body, tighten the chain with a screwdriver and tighten the bolts again.
• Lock the instrument while carrying it to the object.

The chainsaw is ready to go, but before you activate it, don't forget to put on your basic protective gear: overalls, boots, gloves, and a hard hat with a visor and earmuffs.

Disable blocking directly on the object. To start the saw, pull the starter sharply.

To cut down a tree without much effort, cut a wedge-shaped piece to about the middle of the trunk. First make a cut, holding the blade with a downward slope, and then at an upward angle. After pruning from the back, the tree will give way and fall towards the wedge.

Before sawing off the branches, securely lay the trunk. If it is not possible to cut all branches at once, clean one half of the log first, then turn the log over and cut the remaining branches on the other side.

Caution: Never allow the saw blade to come into contact with the ground. This may result in serious damage to the instrument.

In any situation, one should not forget that a chainsaw is a source of danger. Be sure to read the operating instructions for the chainsaw before using it for the first time. Many users prefer to focus on many years of experience with this technique and do not use the manual at all. You should not read the instructions after something has happened to the chainsaw, it is best to think about it in advance and protect yourself in advance.

Power saw device

Chainsaws "Ural", "Druzhba" and "Druzhba-Altai" consist of such main components as the engine, clutch, gearbox, saw unit, frame with handles and starter controls.

The main components of the engine are the cylinder, crankcase, crankshaft with connecting rod, cooling system, piston, ignition and power system.
The clutch includes a drive disk, on the rim of which there are two cut cast-iron rings, and a driven disk with a rim in the form of the letter "G".

The gearbox is represented by a housing and two bevel gears: driven and driven, which are mounted on ball bearings in the housing. The frame consists of a rack and a steering wheel with handles, which are interconnected by a vibration damping device, which consists of a hinge and a spring.

The saw unit is represented by a saw chain and a bar. The power system includes components such as a gas tank, a crane and a carburetor. The supply of fuel from the gas tank to the carburetor with the valve open is carried out through the gas pipeline by gravity. The engine is started by a removable starter, consisting of a pin, brakes, ratchet, bolts, roller, drum, housing, cable, spring, handle and bushing.

Working with a chainsaw

All buyers of petrol saws want to test their purchase in real conditions as soon as possible. Remember that you should not start the chainsaw without a saw set and preliminary adjustment of the tire, chain and sprocket - the drive wheel. There is a possibility that the clutch may burn out with constant pressing of the damper button.

Just before intensive work, it is necessary that the tire, sprocket and chain get used to each other. And you need to break in the engine itself, while emptying the entire fuel tank and applying little effort. Do not break in the saw at idle, as this may cause increased engine wear.

Turn the ignition switch to the working position before starting the chainsaw, pump gasoline into the carburetor, pull out the choke and pull the pull starter with a strong jerk. If you spin the engine with a sluggish pull starter, then the probability of filling the candle increases, and attempts to start the engine will be reduced to zero. In this case, the candle must be unscrewed and heated so that all the vapor of the fuel mixture evaporates under heating.

The main points of work in the operating instructions for the Ural chainsaw, friendship, goodluck and others are as follows:

1. The chainsaw must be held with both hands, clasp the chainsaw handle with all fingers. Place your thumb on your left hand under the front handle.
2. When working with a chainsaw, you must stand to the side of this tool; you cannot stand directly behind it.
3. For sawing, it is customary to use the lower and upper edges of the chainsaw. If you prefer to cut with the top edge, then the chainsaw goes towards you, otherwise - away from you.
4. If possible, keep your back straight when working with a chainsaw. It is preferable to bend your legs at the knees. To maintain balance, it is advisable to spread your legs wider.
5. It is very dangerous to move around with a running chainsaw. When crossing between sawing places, it is necessary to turn off the chainsaw for safety reasons and put on the brake.
6. It is better to start sawing with the edge of the tire, which is located closer to the body of the chainsaw.
7. If you plan to use your chainsaw often, then it is advisable to re-read the instruction manual for the Husqvarna chainsaw, friendship, ural, etc. and purchase special protective clothing: a protective jacket with ventilation, a helmet with a mask, special trousers with protection against saw cuts, boots with protective steel plates and durable gloves.

Seasonal use

Two-stroke internal combustion engines require special attention during the change of seasons of operation. When using a gasoline-powered saw with a window temperature below 0 degrees, you need to warm up the carburetor itself, since the fuel mixture can crystallize, while increasing the viscosity of the mixture. The saw itself in this case must adapt to a similar temperature regime.

If the chainsaw is kept in an unheated building, in which it is less than zero degrees Celsius, it is undesirable to bring it immediately into a room where the air temperature rises above 0 ° C, otherwise condensation may form, which will lead to malfunctions of the equipment and other negative consequences.

fuel mixture

All saws are equipped with 2-stroke internal combustion engines. There are two tanks: for the fuel mixture and oil. The volume of the tank in the usual case is about 0.3-1 liter, and the vessel for oil, as a rule, is 2 times smaller. These proportions lead to the fact that after the fuel mixture in the tank has ended, the oil is almost equally consumed.

A chainsaw with a two-stroke engine, according to the instruction manual for a chainsaw friendship, Ural, Goodluck, Calm, Hustkvarna, is usually refueled with a mixture, and not with gasoline, which contains oil and gasoline in certain proportions. The process of preparing the fuel mixture for such engines is very important, so do not neglect the requirements of manufacturers for its manufacture. In a two-stroke engine, friction parts are lubricated, unlike a four-stroke engine, due to the fuel mixture, in which a certain part of the oil is present.

In two-stroke engines, an oil pump system cannot be used; it is customary to add oil to gasoline. Before direct filling of the fuel mixture, it is recommended to shake it thoroughly. For chainsaws, as a rule, a fuel mixture is prepared from oil and gasoline. It will take 40 milliliters of oil and 1000 milliliters of gasoline. Mix the mixture thoroughly before pouring into the fuel tank.

When making a mixture for a chainsaw, it is recommended to use only branded oils. The suggested brands of oil that should be used to prepare the mixture are indicated in the instructions. It is forbidden to use two-stroke oils for low-speed engines.
Gasoline is best used unleaded. The octane number of gasoline must be at least 90. The finished fuel mixture must be stored for no more than 1.5 months. The use of the old mixture will certainly cause the engine to fail.

To lubricate the chain, you can use any pure oils or branded special ones. For a domestic chainsaw, the 76th gasoline is suitable; for an imported one, it is better to take the 92nd and higher. Do not use used oil or oils with low viscosity - spindle, industrial and transformer oils to lubricate the chain. Before starting the chainsaw, it must be removed from the place where refueling took place, in order to avoid ignition.

Running in a chainsaw

Before using any imported chainsaw, it is required to pre-run it. On the one hand, it is needed to extend the life of the engine, because moving parts during the break-in period must first run in to each other. In addition, during the break-in, you will be able to acquire certain skills in working with a gasoline-powered saw. This is important for those users who read the instruction manual for the Makita chainsaw for the first time, friendship, ural, calm and work with a chainsaw.

Running in the chainsaw must be done with minimum load on the engine in a cyclic mode of operation: sawing lasts 1-1.5 minutes, then idling for 15-20 seconds. The motor will gain maximum power after ten full tank refills. You can not run the engine at idle, because the formation of a large amount of soot provokes the occurrence of piston rings or the failure of the spark plug.

Preparing the chainsaw for work

Check the chainsaw first for chain tension, which should be adjusted, chain slack is unacceptable. Poor chain tension can wear out the tire and sprocket faster than expected, greatly increase the load on the saw body and prematurely disable the shock absorbers.

The chainsaw chain should not touch hard objects, turn on the chain brake, move the brake handle away from you so that the chain does not rotate ahead of time. Pull the choke lever out, this can be done when the engine is cold. Slip your toe into the rear handle. Pull out the starter cord by pulling on the handle until the chainsaw sneezes.

After that, start the chainsaw and move the air damper to the working position. Step on the gas and move the chainsaw to idle. Pull the brake lever towards you to return it to its original position. Now the chainsaw is ready to work!

Check the tool brake before starting work. Next is to install the saw on a flat and hard surface and press the throttle. Do not release the chainsaw handle, press the handle and apply the brake. The brake will be considered OK when the chainsaw chain is stopped.

Before you start the chainsaw, you should definitely check the presence of chain oil in the reservoir. In the absence of lubrication at high speed, problems with the chain and bar may occur. You can check the presence of lubrication during operation. With the chainsaw running at high speeds, it is necessary to direct the tire onto clean paper. If the lubricant is flowing normally, a streak of oil will be visible on the sheet.

How to cut down trees

Just before felling a tree, it is necessary to read other chain saws and determine where it will fall. Look at the number of branches, and where the main ones are facing, it is worth considering the direction of the wind and the natural slope of the trunk. It is necessary to bring down the trunk in the direction where it is more convenient for it to fall. Cut off the lower branches of the tree right before felling.

Depending on the thickness of the tree and other features, there are several methods for felling a tree, the most optimal solution selected only by professional lumberjacks. Before felling a tree, you should make sure that it will not damage anything after falling.

Stand from the trunk of a fallen tree on the left, cut the branches from it, move from the bottom of the trunk. Try not to use the nose of the chainsaw, work slowly. Lean the chainsaw against your hip or tree trunk and use all parts of the bar for sawing. Lay the chain saw on its side, with all the weight on the trunk, cut the branches from the top of the trunk. When the branches are cut from above and from the sides, the trunk can be turned over and sawed off the rest.

At the same time, remember that at a certain position of the tree, which rests on one branch, the trunk may move or roll when it is cut. With thick and large branches, it is necessary to saw off in parts, moving from its end. If the branch is too thick, then it may need to be filed from several sides.

When you sawed off all the branches from the trunk, you can start sawing the trunk - its bucking. Bucking must be started from the trunk to the top. If the trunk is located on an inclined plane, then when bucking it is forbidden to stand below the tree trunk. If the chain saw is stuck in the barrel, then it must be removed immediately. Stop the engine and tilt the barrel until you can remove the chainsaw.

Chainsaw Care

Power saws should be kept under a canopy or in open areas. Before putting the tool into storage, it must be cleaned of sawdust and dirt, the fuel must be drained from the tank, the saw chain removed and placed in oil. Open places that are exposed to corrosion must be lubricated with a layer of oil. A chainsaw for long-term storage must be mothballed.

After working with a chain saw, you must do the following:

• Check chainsaw tension and lubrication. If the oil runs out, you need to add it to the tank and tighten the chain if it is loose. Let the tool rest and cool down a bit, then fill the saw with gasoline.
• Do not forget to check the air filter, which can become clogged with chips and sawdust during operation. Therefore, it must be removed, blown and washed in time. If necessary, clean the filter from dirt.
• After every hour that the chainsaw has been running, the driven sprocket of the tire must be lubricated and immersed in heated oil.
• After 25 hours of operation, dust must be removed from the cylinder windows, combustion chamber, piston grooves, rings and piston crown.

Engine starting

It is necessary to carefully read the operating instructions for the stihl chainsaw, friendship, calm, ural, especially the sections that relate to starting a cold and hot engine. The principle of starting the engine is the same in all saws. The differences are only in the placement of the controls of the chainsaw - the choke lever and the STOP button.

With separate controls

Start a cold engine in the following way:

• move the switch to the "on" position;
• pull the choke lever all the way;
• move the choke lever to the middle position (choke is open, the position of the increased idling remains on);
• repeat the startup procedure;
• after starting the engine, immediately press and release the gas trigger - the choke lever will automatically move to the working position.

You need to start a warm engine like this:

• turn the switch to the "on" position;
• pull the choke lever out to failure, then move it to the middle position, or do not touch it and leave it in the traditional idle position;
• perform the procedure for starting the engine;
• when the choke lever is in the position of increased idling, after starting the engine, press the gas trigger and release it;
• the engine can be stopped by moving the switch to position 0 (off).

With combined controls

You can start a cold engine in the following sequence:

• simultaneously press the gas trigger lever and move the damper control shaft to the lowest position, the air damper in this case is completely closed;
• pull the starter cord handle several times until the first flash in the fuel engine;
• move the control shaft to the middle position;
• repeat the procedure for starting the engine;
• after starting the engine, press and release the gas trigger, the control shaft in this case automatically switches to working position I.

Starting a warm engine according to the operating instructions for a Stihl chainsaw and any other gasoline-powered tool is carried out as follows:

• move the control shaft to the normal idle position;
• start the engine;
• press and release the throttle trigger with the shaft in the high idle position.

Rules for safe work

• It is strictly forbidden to work with an unadjusted and faulty chain saw.
• When starting the engine, do not wind the cable around your hand.
• When starting the engine, the chain should not touch any objects.
• To avoid chainsaw breakage and accidents when felling a falling tree, do not cut through the tree. You should leave 3-4 centimeters of underdrink.
• Switch off the chain when moving from one tree to another.
• Work on installing the chainsaw chain and adjusting its tension level should be carried out with the engine off, wearing a protective helmet and gloves.
• After refueling the chainsaw with oil and fuel, carefully remove any remaining oil and fuel from its surface, wipe it dry.
• It is forbidden to fell a tree over which another hangs, as well as to fell heavily overhanging or tilted trees in view of the danger of such an operation for the life of sawflies.
• When felling a tree, only the sawyer and his assistant can stay at the chainsaw, other people must be at least 50 meters away from the working tool. The assistant warns the sawyer with a voice or a signal about the beginning of the fall of the tree.
• Before the end of sawing, the sawyer with an assistant should carefully monitor the direction of the fall of the tree, moving quickly to the side with the saw, but not against the butt of the tree.
• Crossings through a moving chain are prohibited. In the event of a run or open circuit, immediately release the gas and turn off the engine. The saw chain may only be put on the bar when the engine is not running.
• When refueling a chainsaw according to the operating instructions for a huskvarna, goodluck, ural, calm and other chainsaws, it is forbidden to smoke.
• It is strictly forbidden to refuel a chainsaw at a distance of less than 20 meters from an open flame.
• The carburetor should be adjusted so as to provide the least contamination of the exhaust gas inhalation zone, and a stable idle speed of the engine, at which the saw chain does not move along the bar.
• When moving over a long distance, the chainsaw engine should be turned off and tightly covered with a special cover.
• Felling trees with a gasoline-powered saw must be carried out exclusively in a prepared cutting area, where dangerous hanging and dead trees have been removed.

And finally, remember that a chainsaw is a rather complicated device, so any mechanism can fail. An important role is played by the location near the service center and the availability of a guarantee for the chainsaw.

Choosing the right chainsaw for yourself is not the most difficult thing, extending its service life is much more difficult. The first thing before the person who bought it is the task of running it in. This procedure is mandatory and is key in the life of the instrument. You can't just start a new one. chain saw and start working. It must be fully checked and prepared before starting to perform its tasks. Should be used as chainsaw operation can be dangerous. When sawing wood, chips fly, so you should protect your eyes. Also, when working with tools, it is better to wear gloves so as not to injure your hands.

Why do I need to break in a new chainsaw

This is a complex process that requires a responsible approach. The chainsaw is not the exception, but rather the rule. All tools with a two-stroke engine require break-in. Without proper break-in, the life of the tool will be much shorter, and it will perform worse. Everyone who buys this tool should know how to break in a chainsaw.

Why do it? During these manipulations, grinding of engine parts and a saw set is carried out.

You need to understand that you need to study the instructions for the tool in detail. You must remember it and use all the recommendations. There is also a lot of information about what not to do or what must be done. If you are a “layman” and have never experienced running a chainsaw, the instructions for your tool should become your reference book.

How to break in a chainsaw: step by step instructions

Before running in, the first start of the chainsaw takes place. Be sure to prepare and properly install the headset. The fuel mixture should already be waiting in the wings, from it in more depends on the quality of the wrap.

Here in front of you lies a new, sparkling instrument. Looking at him, the question arises: “What should be done now?”. After reading the instructions, you find out that a run-in is needed and the first start should be special. How to start a new chainsaw is not yet clear, but now everything will become clear.

We always do the first launch with a headset. You should not start the engine without a tire and: the tool must work with them, so it will receive the proper load. Do not make high speeds, this will negatively affect the further operation of the saw.

After installing the headset, you need to do the following things:

• Make a fuel mixture;
• Check the lubricant and make sure the bar is getting oil and the chain is constantly lubricated.

Choice of chainsaw oil

Especially it is necessary to pay attention to the choice of oil, the operation of the entire tool depends on it. The higher its quality, the longer and more efficiently the chainsaw will serve. You need to buy a special one that is made specifically for such engines. When using the wrong lubricant, frequent problems will be:

• Engine breakdowns;
• Ignition problems;
• The chainsaw will stall, and sometimes simply refuse to start;
• Saw overheating.

Different parts require different lubricants - one oil is not suitable for all tasks. The choice of this material is one of the most important things when interacting with a chainsaw. The life expectancy of the tool depends on the decision made.

Special lubricants have been created for Foresta saws and motor oil will do an excellent job of protecting the “heart” of the tool. The chain lubricant is not suitable for the motor, otherwise the life of the tool may be reduced. Even if the oil is of high quality, but is not used for its intended purpose, nothing good will come of it.

Foresta saws are specially made with proprietary lubricants that make working with them easier and additionally protect against overheating.

Fuel mixture for first start

More than half of the chain saws on the market use two-stroke engines. For such engines, there is no special oil for active parts. You have to make a special lubricant that can replace it. For manufacturing, you will need good quality gasoline and engine oil recommended by the manufacturer.

The choice of components for the mixture

The basis for our mixture will be gasoline. You need to take an oil product with an octane rating of more than 90. You should not save and take dubious fuel, then you will pay more for repairs. Octane boosters are also a dubious choice.

Owners have a choice between leaded and unleaded gasoline. For an engine without a catalyst, you need to take the first option, respectively, if a catalyst is installed, we take the second type.

The choice of oil is not difficult, just take a branded lubricant from a chainsaw manufacturer company.

If there is no branded one, use JASOFB or ISOEGB class oils.

Fuel mixture manufacturing

To break in the tool, the fuel mixture is made in accordance with a ratio of 1:25, where 40 ml of oil is needed for 1 liter of gasoline. Be sure to respect the proportions, non-compliance can be fatal to the device.

We take a washed vessel and do everything according to the instructions:

• Pour half of the required gasoline into the container;
• Pour out all the oil;
• Stir the resulting substance;
• Add the remaining gasoline and mix.

The video shows how to make it, just do not forget about the proportions. They differ depending on the chainsaw.

Checking for lubrication

Now the important step, we need to check the lubrication. Please note that this is always done, it does not matter here what time you work with the saw. This will protect the tool from unexpected breakdowns and overheating. You need to check the following points:

• How much oil is left in the tank;
• The condition of the channels of the saw blade;
• Grease should be on the needle bearing of the drive sprocket;
• Is there any lubrication on the driven sprocket.

If you see that the channels are clogged, be sure to clean them and lubricate everything. Tests have shown that Foresta chainsaws consume 40% less fuel and lubricants. This makes it much easier to work with them.

The first start of a chainsaw: step by step

After completing all the above steps, we proceed to launch. The motor of our saw is not heated, so a cold start is performed. We put the tool in a stable position, and then follow the instructions:

1. We put the chain brake in the off position;
2. Turn on the ignition;
3. We put the air supply damper in the closed position;
4. If the saw has a decompression valve, close it;
5. We put the throttle valve in the starting position;
6. With the left hand, we take the front handle of the chainsaw and pull it down;
7. We hold the protective shield of the right handle with our foot;
8. With your right hand, pull the starter handle until the ratchet pawls engage with the starter drum.
9. When you start to feel a little resistance, make a sharp jerk towards you.
10. You will see a flash in the combustion chamber, after which you need to return the air damper to its original place;
11. We start the chainsaw again;
12. The engine is running, at this point you need to release the throttle.

Stages of running in a new chainsaw

You have successfully started the saw, now it's time to break in the new tool. It is assumed that you have already studied the instructions and know what not to do. The run-in itself includes 2 main stages, each stage affects different parts and prepares them for work. Let's consider these stages in more detail.

The owner of a private house, cottage or cottage sometimes needs to cut wood. In this case, you need to purchase special equipment. A chainsaw is in some cases an indispensable tool. To work quickly and safely, before using the equipment, you must read the detailed instructions for this process.

Every master should know. If you do not follow the rules specified by the manufacturer of such equipment, there is a high risk of accidents. Therefore, before operation, it is imperative to consider in detail all the subtleties of the operation of the equipment.

Equipment Features

Starting to study the issue How to use a Husqvarna chainsaw"Calm", "Friendship" or other varieties of similar equipment, you need to delve into the features of each instrument. All existing varieties are conditionally divided into three groups.

Household appliances belong to the first class. They are used for private use when performing a small amount of work. Such chainsaws have low power. But for home master such functionality will be more than enough. It is relatively inexpensive and lightweight equipment.

Semi-professional chainsaws allow you to cut down trees. With their help, they also produce construction or repair work. The operating time of the tool does not exceed 8 hours a day.

Professional chainsaws are able to work up to 16 hours a day. The time of their continuous operation reaches 9 hours. This is expensive, heavy equipment. Only specialized companies and enterprises can afford to buy it.

Features of domestic chainsaws

The domestic tool has certain design features. To operate them correctly, you need to study The most common tools in this category are "Friendship", "Friendship-Altai" and "Ural". They have been on the market for a long time.

To understand how to use the Druzhba chainsaw and other brands, you need to consider their device. The equipment has an engine and a clutch, there is also a gearbox. Be sure to come with a sawing machine. To be able to control the operation of the starter, special design elements are provided.

The power system has a gas tank, carburetor and tap. By gravity, fuel enters the carburetor through the gas pipeline with the tap open. The removable starter starts the engine. All these systems must work properly in order to ensure the normal functioning of the equipment.

Features of foreign chainsaws

The most popular today are the Husqvarna and Shtil chainsaws. Their device is similar to domestic varieties of instruments. However, their device has several features. They should be studied before How to use a Stihl chainsaw or Husqvarna.

The presented equipment of foreign companies is characterized by relatively low weight. This makes work much more comfortable. Husqvarna has a gas suction function. This is very convenient if a situation has occurred when the gas has run out and the engine has stalled. At the next refueling, this function will allow the saw to start immediately.

"Calm" has a quick-release cover, which is very convenient in case of filling the candle with gasoline. Bolt-on devices cause certain difficulties. In this case, fastening must be done with only one screw. Foreign equipment has a large set of additional functions. However, the operating rules for all types of chainsaws are common.

Tool preparation

Considering how to use a chainsaw, you should start with a detailed study of the manufacturer's instructions. Here are all the details of the operation of the equipment.

Before starting work, the tool must be checked. Start with To do this, it is pulled by the upper link. Ideally, the shank comes out of the groove by a few millimeters. In this case, the lower section of the chain should not sag. Otherwise, the chain must be tightened. After that, it should stretch easily. Strong tension is also unacceptable.

The handle of the inertial brake must not come into contact with the main handle. Otherwise, when the saw is operated, the clutch will shift. An elementary initial check can significantly reduce the likelihood of equipment failure.

Refueling

Considering how to use a chainsaw Stihl, Jonsered, Husqvarna, Partner and other models, attention should be paid to the refueling process. Almost all of the presented types of devices have a two-stroke engine. It is not capable of running on a pure gasoline mixture. Therefore, the fuel is prepared from certain components.

To prepare fuel, you will need to take 20 g of engine oil for 1 liter of gasoline. Gasoline should be A92 for domestic instruments and A95 for expensive foreign models. Recommendations for selection are indicated in the manufacturer's instructions.

Engine oil must be specifically designed for chainsaws. Conventional automotive varieties in this case are not suitable. In a plastic container, mix oil with gasoline. The resulting mixture must be poured into the tank. Its hole is marked with a gas station icon. The mouth of the oil container is marked with a drop.

Chain lubrication

In order for the equipment to work for a long time, and its functioning to be of high quality, it is necessary to periodically add lubricant to the chain. Most often, manufacturers recommend using only branded oils. If the user decides to use a different tool, you can replace the special lubricant with automotive varieties. The viscosity of such a product must correspond to the level indicated by the manufacturer.

After choosing the right lubricant, you need to understand how to use a measuring container for a chainsaw. The marks are located near the neck. When working with the presented equipment, it is necessary to periodically check the oil level inside the saw.

It is recommended to lubricate the tire bearing once a month. It is located on its outer end part. If the design provides for a special hole, oil is poured there. Just a few drops are enough. Refueling with oil and fuel should only be done on a hard, level surface.

Safety

studying, how to use a chainsaw, the safety regulations must be considered. This will help prevent accidents while using the tool. All rules are specified in the instruction manual.

During operation, the saw should be held firmly with both hands. The thumb of the left hand should be placed under the front handle. It is necessary to stand on wide-spaced legs to the side of the saw. Do not stand directly behind the instrument. The back is not bent. It must be even.

If the master needs to move to another position, the equipment must be put on the brake. If this rule is neglected, there is a high probability of serious injury. It is necessary to start sawing with the end of the tire.

It is extremely important to wear overalls and protective equipment. These include goggles, special pants and a lined jacket, as well as tight shoes with steel inserts.

launch

The procedure for starting a chainsaw must be carried out carefully and in a certain sequence. The tool must be placed on a flat, solid surface. The chain must not come into contact with any objects.

Next, consider how to use the chain brake on a chainsaw. To activate it, turn the handle away from you. This will prevent the chain from immediately starting to spin on startup. If your particular saw model has a decompression valve, it should also be activated.

The choke lever must be removed. The toe of the right foot should be placed in the handle behind the saw, and the front foot should be held with the left hand. Pull the starter cord quickly several times. The engine will make a characteristic sound similar to sneezing. This means that the tool has been activated.

After that, the air damper must be returned to its original position. After that, you can start the saw. To do this, you need to continue to pull out the starter cord. The engine needs to warm up. At this time, do not remove the brake (fuse).

felling process

Considering how to use a chainsaw, it is necessary to pay attention to the cutting process. There should be no strangers in the work area. When you need to determine the correct direction. The slope of the terrain and the trunk itself, the strength and direction of the wind should be taken into account. This will make it easier to determine where the tree will fall.

The space around must be cleared of shrubs and overgrowth. There should be no foreign objects under your feet. There should be no foreign objects or people within a radius of two lengths.

The guide notch is made low. This makes it easier to drop the barrel. When the tree is felled, you need to stand on the left. The barrel must be fixed so that it does not move during operation. Branches are cut from below. The cut is made with the top of the saw.

Tool maintenance

Having studied the methodology how to use a chainsaw, attention must be paid to proper maintenance. After completion of work, the instrument should be assessed for integrity. Lubricate the chain if necessary.

Particular attention must be paid to the health of the fuse, control levers and catcher. The mechanism must not be damaged. Fasteners must be tightly tightened.

After use, the instrument should be thoroughly cleaned. To do this, open the cover and remove dirt from the brake band. You should also clean the tire. The air filter must be washed from small particles of wood. The cooling fins are wiped, the ventilation holes are cleaned. You also need to inspect the flywheel blades.

Chain sharpening

With intensive work, the tool may require maintenance of the cutting blade even in the process of cutting one trunk. Therefore, it should be considered how to use the machine The procedure can also be performed with files, but in this case the process will be lengthy and less effective.

There are many types of such equipment on the market. Following the manufacturer's instructions, you can set all the necessary sharpening parameters. In this case, the work will be done quickly and efficiently.

Having considered the features of the operation of chainsaws, carefully studying the manufacturer's instructions, you can ensure high safety for the master, as well as a long tool life.
