Chainsaw reference instruction manual. Chainsaw work: 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 are correct, fully meeting 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, grasping the handles with all fingers. In this case, the thumb of the left hand should be under the front grip;
• during work, it is impossible to stand directly behind the saw, it is advisable to be slightly to the side of the tool;
• sawing can be done both with the lower and upper edges of the tool. If you cut with the bottom edge, the chain will guide the saw away from you, and if you cut with the top edge, the chain will move the saw towards you;
• when using the chainsaw, try not to bend your back; instead, bend your knees. When working with the saw in a standing position, it is recommended to keep your legs wide apart to maintain balance;
• before moving to another location, you must activate the saw brake or turn off the engine of the tool. You cannot move with a tool with a chain rotating;
• sawing should start 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 imperative to purchase a set of protective clothing: a helmet with a mask, a bright protective jacket that does not allow air to pass through, special trousers with cut protection, strong gloves and strong boots, which should be protected if possible steel plates.

Currently, a large number of chainsaws can be found on the Russian market, 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 low power, but they do very well with all their duties. 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 control 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 for 8-10 hours a day. It is for this reason that they are called semi-professional. Most often, lumberjacks use these saws as loppers.
3. The third class includes professional saws that are excellent solution for people who specialize in deforestation. Such devices can be used for 10-15 hours a day, while allowing them 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 people think that they already understand everything and do not even look into 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 - while the shank should come out of the tire groove 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 too strong, then loosen it. Next, you need to check in what position the inertial brake is located - its handle and the main handle should not touch, since when the chainsaw is turned on with an offset inertial brake, the clutch may be damaged.

After checking the chain tension, you can start threading the tool. To do this, place the chainsaw on a horizontal surface and fill it with chain oil and fuel mixture. 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 to 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 prolong the life of the cutting element and engine parts. At the end of the test, following all the procedures described above, you can start the saw.

Remember that before starting the engine, remove the saw from the place where it was refueled so that there is no fire hazard when starting. Place it on a stable, solid base.

First start

After making sure that the chain is not in contact with any surfaces, you must apply the chain brake by moving the brake lever 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 thread the toe of your 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 move the air damper to the operating position and start the saw by briefly pressing the throttle and moving the saw to idle. After that, you need to move the brake lever to the position for 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 operational when the chain stops.
• among other things, the lubrication mechanism must be checked before starting work. To do this, you need to find any bright surface, start the tool and, holding it above 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 done with a section of the tire as close to the body as possible. Remember that for different materials you must use your own cutting methods.

Pruning branches

It is best to start trimming the trunk of a felled tree from the branches from the bottom, while being on the left side of it. Work should be done at a calm, slow pace, being careful not to use the nose of the saw. You can cut both the bottom and the top of the bar, trying to lean the saw against the trunk or thigh if possible. 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 top, you can turn the trunk over and start cutting the branches that are below.

Remember:

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

Bucking should be started only after all branches have been cut from the trunk. You need to saw the trunk of a felled 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, 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 you start cutting down a tree, you need to determine as accurately as possible where the tree trunk will be "more convenient" to fall. To do this, take into account how many branches are located on each side of it, as well as the direction of the wind and the natural inclination of the trunk. The tree must be felled in the direction where it is "more convenient" to fall. Before direct felling of the tree, it is necessary to cut the lower branches so that they do not interfere with the work. Currently, there are several different technologies for felling trees, which should be selected depending on many factors. Choose the most optimal 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, which is at least two lengths of the trunk of the tree that you are going to cut down;
• before felling a tree, be sure to make sure that there is nothing nearby that can be damaged by its fall;
• felling trees is enough difficult task, therefore, if you do not have such experience, it is better not to take on it, but entrust it to professionals. As a last resort, you can ask them to attend the felling.

Instrument care

Every time after work with the chainsaw is finished, a number of steps should be taken to care for it:

1. First you need to check the chain lubrication and chain tension. When loosening the chain, you need to tighten it, and if you run out of oil, just add it to the tank.
2. Allow the saw to cool down after completing all work and refuel after a short rest.
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 out. In addition, the surface around the cooling fins needs to be cleaned from time to time.

If you use the chainsaw very often, you will have to change some of the wearing parts - parts of the anti-vibration system, the drive sprocket, the bar and the chain, since not replacing the worn out part in time can end up with its negative impact on the general condition of the tool.

When buying a chainsaw, remember that it is a complex technical device that requires special skills and proper 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 break down from some trifle unnoticed by you.

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

Video instruction for working with a gasoline engine

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 tools that run on a gasoline mixture, as they are more powerful and more mobile than their 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.

Highlights preparatory work, are described in this video instructions on 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 tank with the fuel mixture and, if necessary, lubricating oil.
• Check that the power button and two levers on the saw are working.
• Extend the throttle lever before starting the engine.
• Move the chain brake handle slightly back, which is responsible for the emergency stop of the chain in an emergency.
• Be sure to check the chain tension. Sagging is absolutely unacceptable. To remedy the situation, loosen the two bolts on the saw body, tighten the chain with a screwdriver and retighten the bolts.
• Lock the instrument while carrying it to the object.

The chainsaw is ready to go, but before activating it, be sure to wear basic protective equipment: overalls, boots, gloves, and a hard hat with visor and ear muffs.

Disable the lock on site. Pull the starter firmly to start the saw.

To cut the tree down effortlessly, cut the wedge-shaped piece to about the middle of the trunk. Make the cut first by holding the blade at a downward angle and then at an upward angle. After pruning from the back side, the tree will give in and fall towards the wedge.

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

Caution: Never allow the saw blade to contact the ground. This can cause serious damage to the tool.

In all situations, remember that the saw is a source of danger. Before using for the first time, be sure to read the instruction manual for the chainsaws. Many users prefer to rely on years of experience with this technique and do not use the tutorial at all. You should not read the instructions after something happened to the chainsaw, it is best to think about it in advance and secure yourself well in advance.

Petrol saw device

Chainsaws "Ural", "Druzhba" and "Druzhba-Altai" consist of such main units as an engine, a clutch, a gearbox, a saw unit, a 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 disc, on the rim of which there are two cut cast iron rings, and a driven disc with a rim in the shape of the letter "L".

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 tap and a carburetor. The supply of fuel from the gas tank to the carburetor with the tap open is carried out through the gas line 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 gas-powered saws want to quickly test their purchase in real conditions. Remember that you should not start the chainsaw without a saw headset and presetting the bar, chain and sprocket - the drive wheel. There is a possibility that the clutch can be burnt by constant pressing of the throttle button.

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

Turn the ignition switch to the working position before starting the chainsaw, pump gasoline into the carburetor, pull out the suction and pull the retractable starter with a strong jerk. If you spin the engine sluggishly with a pull-back starter, then the probability of filling the spark plug 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 boil down to the following:

1. Hold the chainsaw with both hands, grasp the handle of the chainsaw with all your fingers. Place your left thumb under the front grip.
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 is going towards you, otherwise - away from you.
4. Whenever possible, keep your back straight when using your 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. For safety reasons, switch off the chainsaw and apply the brakes when crossing between sawing points.
6. It is better to start sawing with the edge of the bar, which is closer to the body of the petrol saw.
7. If you plan to use your chainsaw often, then it is advisable to re-read the operating instructions for the chainsaw husqvarna, friendship, ural, etc. and purchase special protective clothing: a protective jacket with ventilation, a helmet with a mask, special trousers with the provided protection against saw cuts, boots with protective steel plates and durable gloves.

Seasonal use

Two-stroke internal combustion engines require special attention to themselves during the period of changing seasons of operation. When using a gasoline saw with a temperature outside the window below 0 degrees, you need to warm up the carburetor itself, since the fuel mixture is capable of crystallizing, 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 directly into a room where the air temperature rises above 0 ° C, since otherwise condensation may form, which entails malfunctions in the operation of equipment and other negative consequences.

Fuel mixture

All chainsaws 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 less. These proportions lead to the fact that after the fuel mixture in the tank has run out, oil is consumed almost equally.

It is customary to fill a chainsaw with a two-stroke engine according to the instruction manual for the chainsaw friendship, ural, goodluck, calm, Khustkvarna, it is customary to fill it with a mixture, and not gasoline, which contains oil and gasoline in certain proportions. The process of preparing the fuel mixture for such engines is very important, so you should not neglect the manufacturer's requirements for its manufacture. In a two-stroke engine for lubrication of parts, friction, in contrast to a four-stroke, is due to a fuel mixture, in which a certain part of the oil is present.

In two-stroke engines, the oil pump system cannot be used; it is customary to add oil to gasoline. It is recommended to shake it thoroughly before pouring the fuel mixture directly. For chainsaws, as a rule, a fuel mixture is prepared from oil and gasoline. You will need 40 milliliters of oil and 1000 milliliters of gasoline. Mix the mixture thoroughly before pouring it 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 ready-made 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 clean oils or brand special ones. For a domestic chainsaw, the 76th gasoline is suitable, for the imported one it is better to take the 92nd and higher. Do not use waste oil or low viscosity oils - spindle, industrial and transformer oil for chain lubrication. Before starting the chainsaw, you need to remove it from the place where the refueling took place in order to avoid ignition.

Chainsaw break-in

Before using any imported chainsaw, it is required to carry out its preliminary running-in. On the one hand, it is needed to extend the life of the engine, because the moving parts during the running-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 gas-powered saw. This is important for those users who first read the instruction manual for the Makita chainsaw, friendship, Ural, calm and work with a chainsaw.

The chainsaw must be run in with minimum load on the engine in a cyclical mode of operation: sawing lasts 1-1.5 minutes, then idling for 15-20 seconds. The motor will acquire maximum power after ten full tank fillings have been used up. Do not run the engine at idle, because the formation of a large amount of carbon deposits provokes piston rings or spark plug failure.

Preparing the chainsaw for work

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

The chainsaw chain should not touch solid objects, apply the chain brake, move the brake handle away from you so that the chain does not rotate ahead of time. Pull out the throttle control lever, this can be done when the engine is cold. Insert the toe into the back handle. Pull out the starter cord by tugging on the handle until the saw sneezes.

After that, start the chainsaw and move the air damper to the working position. Click on the gas and put the chainsaw at idle speed. Pull the brake lever towards you to return to its original position. The chainsaw is now ready for use!

Check the tool brake before starting work. Next, you should set the saw on a flat and solid surface and press the throttle. Do not let go of the chain saw handle, push the handle and apply the brake. The brake will be considered OK when the chainsaw is stopped.

Before starting the chainsaw, be sure to check for the presence of chain oil in the tank. If there is no lubrication at high speed, problems with the chain and bar may appear. You can check the presence of grease during operation. When the chainsaw is operating at high speeds, it is necessary to direct the tire onto clean paper. If the lubricant flows normally, a strip of oil will be visible on the sheet.

How to cut trees

Just before felling a tree, you should read other chainsaws 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 inclination of the trunk. It is necessary to knock down the trunk in the direction where it is more convenient for it to fall. Cut the lower branches of the tree just before felling.

Depending on the thickness of the tree and other features, several methods of felling a tree are distinguished, the most optimal solution selected only by professional lumberjacks. Before felling a tree, make sure it doesn't damage anything after it falls.

Stand from the trunk of the fallen tree to the left, cut off the branches from it, move from the bottom of the trunk. Try not to use the bow 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 petrol saw on one side, with all your weight on the trunk, cut branches from the top of the trunk. When the branches are cut from the top and 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. For thick and large branches, it is necessary to saw off in parts, moving from its end. If the branch is too thick, it may need to be filed from several sides.

When you have cut off all the branches from the trunk, you can start sawing the trunk - bucking it. Bucking should be started from the trunk to the top. If the trunk is located on an inclined plane, then when bucking, do not stand below the tree trunk. If the gasoline 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 shed or in open areas. Before storing the tool, it must be cleaned of sawdust and dirt, the fuel must be drained from the tank, the saw chain must be removed and it must be put in oil. Open places that are subject to corrosion must be lubricated with a layer of oil. The chainsaw must be preserved for long-term storage.

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

• Check the chain saw tension and lubrication. If you run out of oil, 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 shavings and sawdust during operation. Therefore, it must be removed, blown and rinsed in time. If necessary, it is worth cleaning the filter from dirt.
• After every hour, when the chainsaw was working, you need to lubricate the driven sprocket of the tire and immerse it in heated oil.
• After 25 hours of operation, dust should be removed from the cylinder windows, combustion chamber, piston grooves, rings and piston crown.

Engine starting

It is necessary to carefully read the instructions for using 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. Differences are only in the placement of the petrol saw controls - the choke lever and the STOP button.

With separate controls

It is necessary to start a cold engine in this way:

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

You need to start a warm engine like this:

• switch the switch to the "on" position;
• pull out the choke lever until it stops, 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 in the position of increased idle speed of the choke lever 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 throttle trigger and move the choke control shaft to the lowest position, in this case the air damper is completely closed;
• pull the starter cord handle several times until the first flash of fuel in the engine;
• move the control shaft to the middle position;
• repeat the procedure for starting the engine;
• after starting the engine, press and release the throttle trigger, the control shaft in this case automatically switches to operating position I.

Starting a warmed-up engine in accordance with the operating instructions for a chainsaw calm 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 while the shaft is in the extended idle position.

Safe work rules

• It is strictly forbidden to work with an unregulated and faulty petrol-powered 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 damage to the chainsaw and accidents when felling a tree, do not saw through the tree. You should leave 3-4 centimeters of the hinge.
• Turn off the chain when moving from one tree to another.
• Work on installing the chainsaw chain and adjusting its tension level with the engine off, wearing a protective helmet and gloves.
• After refueling the saw with oil and fuel, carefully remove oil and fuel residues from its surface, wipe it dry.
• It is forbidden to cut down a tree over which another is hanging, as well as to cut down heavily overhanging or inclined trees in view of the danger of such an operation for the lives of the sawers.
• When felling a tree, only the sawer and his assistant can remain at the chainsaw, other people must be at least 50 meters away from the working tool. The assistant warns the sawer with a voice or signal that the tree is about to fall.
• Before the end of the sawing process, the sawer and an assistant must carefully monitor the direction of the tree falling, moving quickly to the side with the saw, but not against the butt of the tree.
• Crossings through the moving chain are prohibited. If the chain escapes or breaks, 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 the gasoline saw according to the operating instructions for the huskvarna chainsaw, goodluck, ural, calm and others, do not smoke.
• It is strictly forbidden to refuel the chainsaw at a distance of less than 20 meters from an open flame.
• The carburetor should be adjusted to ensure that the exhaust gas inhalation area is as dirty as possible and that the engine idles at a steady speed so that the saw chain does not move along the tire.
• When carrying it over a long distance, the engine of the chainsaw should be turned off and tightly covered with a special cover.
• Felling of trees with a gasoline-powered saw must be done exclusively in a prepared cutting area, where dangerous hanging and dead trees have been removed.

And finally, remember that the chainsaw is a rather complex 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, it is much more difficult to extend its service life. The first step before the person who bought is the task - to run 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 needs to be fully tested and prepared before starting to perform its tasks. Use as chain saw operation can be hazardous. Wood chips fly when sawing, 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 run 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 2-stroke tools require running-in. Without proper running-in, the life of the tool will be much shorter, and it will perform worse. Everyone who has bought this tool should know how to break in a chainsaw.

Why do this? During these manipulations, the engine parts and saw headset are lapped.

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 occurs. Be sure to prepare and install the headset correctly. The fuel mixture should already be waiting "in the wings", from it in to a greater extent the quality of running-in depends.

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

We definitely do the first launch with a headset. Do 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 revs, this will negatively affect the further operation of the saw.

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

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

Chainsaw oil selection

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, which is made specifically for such engines. When using the wrong lubricant, common problems will be:

• Engine breakdowns;
• Ignition problems;
• The chainsaw will stall, and sometimes it will simply refuse to start;
• Overheating of the saw.

Different parts require different lubricants - one oil will not work for all applications. The choice of this material is one of the most important things when interacting with a chainsaw. The life span of the instrument depends on the decision made.

Special lubricants have been created for Foresta saws and the motor oil is perfect for protecting the “heart” of the tool. The chain lubricant is not suitable for the motor, otherwise the tool life 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 designed with proprietary lubricants that make working with them easier and additionally protect against overheating.

First start fuel mixture

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

The choice of ingredients for the mixture

Our mixture will be based on gasoline. You need to take an oil product, the octane number of which is more than 90. You should not save and take questionable 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 the catalyst is installed, take the second type.

Choosing an oil is easy, just get a proprietary lubricant from your chainsaw manufacturer.

If there is no brand name, use oils of the JASOFB or ISOEGB class.

Fuel mixture preparation

To run the tool in, 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 remaining gasoline and mix.

The video shows how to make it, just don't forget about the proportions. They differ depending on the chainsaw.

Checking the presence of grease

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

• How much oil is left in the tank;
• The condition of the saw blade channels;
• 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 use 40% less fuel and lubricant. This makes it much easier to work with them.

Starting your chainsaw for the first time: step by step

After completing all the above described actions, we proceed to launch. The motor of our saw is not hot, so a cold start is made. We put the instrument in a stable position, and then follow the instructions:

1. We put the chain brake in the inoperative position;
2. Turn on the ignition;
3. Set the air supply flap to 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 your left hand, 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 dash towards you.
10. You will see a flash in the combustion chamber, after that you need to return the air damper to its original place;
11. We start the chainsaw again;
12. The engine is running, at this moment you need to release the throttle valve.

Stages of running in a new chainsaw

You have successfully started the saw, now it is time to run in the new tool. It is assumed that you have already read the instructions and know what not to do. The running-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 summer cottage sometimes needs to cut wood. In this case, you need to purchase special equipment. In some cases, a chainsaw is 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, you should definitely consider in detail all the subtleties of the equipment operation.

Equipment features

Starting to study the issue, how to use the Husqvarna chainsaw, "Calm", "Friendship" or other types of similar equipment, you need to delve into the specifics of each tool. All existing varieties are conventionally divided into three groups.

The first class includes household appliances. They are used for private operation when performing a small amount of work. Such chainsaws have low power. But for home master there will be more than enough such functionality. It is relatively inexpensive and lightweight equipment.

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

Professional chainsaws are capable of working 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 it.

Features of domestic chainsaws

The domestic tool has certain design features. To use them correctly, you need to study. The most common tools in this category are "Druzhba", "Druzhba-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 a motor and a clutch, there is also a gearbox. The sawing device is necessarily included in the kit. To be able to control the operation of the starter, special structural elements are provided.

The power system has a gas tank, carburetor and tap. By gravity, the fuel flows through the gas line with the valve open to the carburetor. The removable starter starts the engine. All of these systems must work properly in order for the equipment to function properly.

Features of foreign chainsaws

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

The presented equipment of foreign companies is relatively lightweight. This makes work much more comfortable. "Husqvarna" has a function for sucking gasoline. This is very convenient if a situation has occurred when gasoline has run out and the engine has stalled. The next time you refuel, this function will start the saw immediately.

"Calm" has a quick-detachable cover, which is very convenient in case of filling a candle with gasoline. Devices with a bolted cover present a challenge. In this case, the fastening must be done with only one screw. Foreign equipment has a wide range of additional functions. However, the operating rules for all types of chainsaws are common.

Instrument preparation

Considering, how to use a chainsaw correctly, you should start with a detailed study of the manufacturer's instructions. All subtleties of equipment operation are indicated here.

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

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

Refueling

Considering, how to use a chainsawStihl, 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. He is not capable of running on a pure gasoline mixture. Therefore, 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 tools and A95 for expensive foreign models. Selection recommendations are indicated in the manufacturer's instructions.

The engine oil must be specially formulated for your chainsaw. Conventional car varieties are not suitable in this case. Stir oil and gasoline in a plastic container. The resulting mixture must be poured into the tank. Its opening is indicated by a gas station icon. The neck 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 was 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 product, the special lubricant can be replaced with automotive varieties. The viscosity of such a product must correspond to the level specified by the manufacturer.

After choosing the right lubricant, you need to understand how to use a measuring container for a chainsaw. 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 at its outer end. If the design provides for a special hole, oil is poured there. Just a few drops are enough. Refuel with oil and fuel only on a firm, level surface.

Safety engineering

Studying, how to use a chainsaw, you need to consider the safety rules. 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. Place your left thumb under the front grip. Stand with your feet wide apart to the side of the saw. Do not stand directly behind the instrument. The back is not bent. It should be flat.

If the master needs to move to another position, the equipment must be braked. If this rule is ignored, there is a high probability of serious injury. It is necessary to start sawing with the end of the bar.

It is imperative to wear protective clothing and protective equipment. These include goggles, special pants and a lined jacket, and heavy-duty shoes with steel inserts.

Running

Chainsaw starting procedure must be followed carefully and in a specific sequence. Place the tool on a firm, level surface. The chain must not come into contact with any objects.

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

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

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

Felling process

Considering, how to use a chainsaw, it is necessary to pay attention to the cutting process. There should be no outsiders in the work area. If necessary, 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 area around must be cleared of bushes 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 cut is made low. This makes it easier to knock down the trunk. 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. The branches are cut from the bottom. The cut is made with the top of the saw.

Tool maintenance

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

Special attention should be paid to the serviceability of the fuse, control levers and catcher. The mechanism must not be damaged. The fasteners must be tight.

The instrument should be thoroughly cleaned after use. 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 to remove small particles of wood. Cooling fins are cleaned, ventilation holes are cleaned. You should also inspect the flywheel blades.

Sharpening the chain

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

There are many types of such equipment on sale. 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 service life of the tool.
