There are many articles on the site dedicated to repair sewing machines... However, first of all, these articles are of an informative nature, intended not for amateur craftsmen, but for the owners of sewing machines.
From them you will learn how this or that sewing machine works, what breakdowns it can have if you do not follow the operating instructions. And finally, how to perform a simple repair of a sewing machine with your own hands, if there is no way to go to the workshop.

In this article, you will learn how the Janome sewing machine works. What is the difference between inexpensive models of Janome machines, what kind of breakdowns they have, and whether it can be repaired on their own.

1. Janome sewing machine with swing shuttle

This model of Janome sewing machine has an oscillating hook type. Such a shuttle is used only by Janome, but also by other sewing machine manufacturers. These are cars of the initial price, which can be bought in the range of 4-5 thousand. They are quite reliable and "hardy", but there are limits to everything, and after when it was on this machine (photo) that we decided to hem several jeans at once, it ended up in our workshop.

Look at the photo. The arrows indicate the nose of the shuttle and the eye of the needle. You can see that when the hook tip approaches the needle, the eye of the needle is too high and therefore no stitches are formed. This is a very common "breakdown". In quotes, because such a failure appears when the rules of operation of any sewing machine are not followed, and Janome is no exception. This is not even a breakdown, but a violation of the parameters of the interaction of the shuttle mechanism and the needle. This happens at the time of excessive load. And doing the finishing line on the hem of the jeans is exactly the case. The toothed belt connecting the upper and lower shaft "slips onto the tooth" and the machine stops making stitches, although it still works normally. Jeans are probably the biggest enemy of all sewing machine manufacturers. How much they undermine the image of any of them. After all, it is jeans that most often disable household sewing machines.

To understand why this happens, and why jeans should not be hemmed on household sewing machines, count how many layers of fabric are formed at the roughest place (the seam joint). From 9 to 12 layers. Take a needle and try to pierce such an area with a hand needle, it is unlikely to work. Only if the needle is hammered.

But let's return to our sewing machine Janome and try to figure out how such a failure occurred and whether it can be fixed on our own.

Firstly, it must be said that if the machine stops forming stitches normally, gaps appear, thread breakage, then look at how the nose of the shuttle interacts with the needle.
Detach the presser foot, stitch plate. Lay the clipper on its side and remove the top of the shuttle course so that the shuttle stays in its slots and is not skewed. Now gently turn the handwheel and bring the hook point towards the needle. If you find such a "picture" as in this photo, then the cause of the malfunction is different and you do not need to disassemble the machine. The photo shows that the nose of the shuttle fits, as it should be, 1.5-2mm above the eye of the needle. If the nose is below the lug or on a level with it, then it will be necessary to disassemble the body of the machine in order to gain access to the unit we need.

I do not recommend disassembling modern sewing machines. There is nothing difficult in this, but only for those who know how to do it correctly. In any other case, there is always a desire to use a nailer. Well, it seems like all the screws are unscrewed, but the case does not come off. Be careful, you can easily break not only the body mount, but also the necessary part of the sewing machine.

Each machine uses its own options for attaching the halves of the case. First you need to carefully study them, discover them. For example, several pieces can be found under the front cover, in the area of \u200b\u200bthe upper thread tensioner, hook mechanism (remove the needle plate).
Further, some of them "hide" under plugs that can be easily removed with a knife blade. What else can you advise. Well, for example, for this model, Janome does not need to remove the levers for switching stitch types. By the way, don't forget about the reverse lever when you put the body back together. In general, for a non-specialist it will be much more difficult not to disassemble it, but to assemble it, keep this in mind. Mark where and which screw was. And if you don't have a single "extra" screw, then you asked for the attentiveness test for 5 points.

4. The device of the Janome sewing machine

If you are going to buy an inexpensive Janome sewing machine, you can see these photos, which show well how it works. This will help you do right choice.
In the next paragraph, you will find out the reason for the malfunction of this sewing machine.

If the copier is dry, grease its grooves.

Check the tension of the drive belt. If it is loose, tighten it slightly with the screws that secure the motor to the housing. The belt should not be overtightened; it should bend slightly when pressed with a finger.

If your sewing machine has "problems" with the upper thread tension, this knot is most likely the cause. Raise and lower the presser foot several times and check that the lever works correctly. It may need to be adjusted.

Behind the upper thread tensioner, there is a housing fastening screw. It is easy to unscrew, but not easy to put back. Put the screwdriver on the magnet for half an hour, and then it will be easier to install.
Do not loosen the tensioner screws when removing the housing cover.

The cause of the malfunction was in this node, marked with an arrow. Moreover, it was not possible to detect this immediately. The toothed belt connecting the main shaft to the lower shaft was not available for this model of Janome sewing machine. Instead, a crank mechanism was used. It is quite reliable and can withstand heavy loads, so the search for the cause of the failure was directed in the other direction.

However, later it turned out that during the hemming of the jeans, the eccentric installed on the main shaft and transmitting movement to the lower shaft shifted. As a result, without load, the parameters of the machine were normal, and when sewing a line was not formed. The mount for this eccentric is inside (arrow).
After setting the correct parameters of the interaction between the needle and the hook nose and then tightening the eccentric fastening (screw), the breakage was eliminated.

Janome sewing machines have many different models designed for various categories of buyers. There are a number of economy-class sewing machines that are affordable for small-scale sewing and home repairs.

The famous Japanese brand Janome is famous for its excellent quality. Sewing machines alone are produced in over 300 models. About a hundred countries have valid contracts for the supply of Janome sewing machines.

This indicator can be used to judge the quality of the manufactured products. Every day, thousands of machines leave the conveyors of enterprises, and the stable demand for them confirms the amazing manufacturability and functionality of the devices. In addition to ready-made machines, the enterprises also produce spare parts for Janome sewing machines, including even.

Like all Japanese equipment, sewing machines of this brand are very reliable and of high quality in terms of manufacturing. However, breakdowns happen to them too. The main reasons for these are negligence in the performance of work and lack of proper care.

Even the best equipment can be rendered unusable without providing it with proper operating conditions. Below we will consider typical breakdowns in which it becomes necessary to repair Janome's sewing machines.

2 Care of your Janome sewing machine

Any technique needs care. This fully applies to sewing machines. With constant work, regular maintenance is also required.

If you begin to notice that the machine begins to malfunction, make noise, skip stitches, sew unevenly or give out some other surprises, then this indicates the need for cleaning and subsequent lubrication. It is also possible that the device requires adjustment.

It is often necessary to adjust the thread tension. In machines of this class (like) such an operation can be performed without difficulty.

If work is not expected in the near future, then the machine can be stored. Before this, the Janome sewing machine must be cleaned from dust and lubricated.

Any preventive cleaning and lubrication is accompanied by the removal of the shuttle. After that, using a special brush, all rubbing surfaces are cleaned from lint and tissue remnants. Oil is poured into the technological holes. Rubbing parts are also lubricated.

The locations to be lubricated are indicated in the instructions for the specific model. It is advisable to lubricate the product no more than once a month, as excessive lubrication can contribute to the opposite effect. Remaining grease must be wiped off with a dry cloth.

After that, the shuttle is installed in place, and final assembly cars. If such work is beyond your strength, and in your locality there is a Janome sewing machine service center or just sewing machine repair, then you can apply for a service there. Otherwise, such preventive measures will have to be performed independently.

Store the sewing machine only in heated rooms with normal humidity. It is unacceptable to leave it in the basement, garage or other premises in the absence of heating.

And do not forget, if you are for a sewing machine, then you also need to diagnose it for faults regularly.

Finding out or at least seeing a photo of how a modern sewing machine works is not only informative, but also useful. Be sure to read this series of articles on repairing modern household sewing machines. A visual representation of the device of a sewing machine will help you make the right choice when buying it, and also make you take more care of it later.

Now we will begin to disassemble the sewing machine, or rather to disconnect its plastic case, which consists of two halves. But first remove the hook cover. To do this, unscrew the screws indicated by the arrows. Just like the front cover, this part, in addition to screws, is also attached to latches. To loosen them, you need to insert a screwdriver into the slot and try to gently slide the cover to the left. On the back of the handwheel, remove the stitch selection knob. Just pull it firmly to the right. Immediately notice how it stood to make it easier to install it back.

And two more types of attachments are located at the bottom of the machine body. In many models of sewing machines, the rubber feet in the lower part of the body are at the same time attaching the plastic body to the metal bed of the sewing machine. In any case, this model of the machine has two rear legs as such an attachment. But since we will only be removing the front part of the case, unscrew only one leg (top right).

For all sewing machines of this class, it is imperative to release the fastener indicated in the photo with the letter (A). Moreover, both screws do not need to be unscrewed, it is enough to release only the front cover. In this case, unscrew the top screw.

4. Unscrew the most difficult to access screw

The very last, but most inconspicuous screw (B) remains. It is located in the back of the front of the machine. Even at high magnification, it is not visible in the photo. The screw that you can see so clearly does not need to be unscrewed. This is the upper thread tensioner attachment. By the way, it remains in place after removing the cover. Consider this point and do not try to shoot it. Actually, unscrewing the screw itself is not difficult, it will be much more difficult to put it back. Therefore, hold the screwdriver on the magnet for a while, this will help you later.

Now you can remove the front cover, although it should be noted that other models may have an additional mount, but the principle is about the same. Look carefully, maybe your car will have an additional mount at the bottom of the case. It happens that the fastening of the covers is hidden by plugs. Use a knife blade to pry the plug on the back of the machine and make sure there is no additional attachment there.

By the way, it is with the help of a knife that you will have to remove the cover, since in addition to screws, there are latches on the ends of the covers. Place the knife blade between the ladles of the case and gently try to move them apart, displacing the latches. Only now it is difficult to determine at once where they are located, so please be patient if you really decided that you definitely need to disassemble the sewing machine.

5. How to disconnect the two body parts

This is approximately the "picture" you will see when you can disassemble your sewing machine. It is probably worth noting that the hardest part is not finding all the screws holding the covers to the case and to each other. It is very difficult to carefully remove the covers, to separate their latches. If you do it hastily, you can damage the plastic, which will ruin not only appearance machines, but will also interfere with work. Rough spots in the sleeve area of \u200b\u200bthe machine will cling to fabrics and even form puffs.

It is important to firmly decide whether you need to disassemble the machine with your own hands or not. If there is no other option, then be patient and attentive. Well, for what it is necessary to disassemble it, we have already mentioned above, but we will understand it in more detail in other articles.

How does a modern household electric sewing machine work. Major malfunctions of components and mechanisms.

Sometimes it becomes necessary to disassemble the sewing machine, or rather to remove the plastic case of the machine in order to gain access to some units. Such a need arises very rarely and it arises only when it is necessary to replace the electric motor of the sewing machine or the drive belt.

Just like the pedal, the electric motor is not worth repairing yourself. Moreover, there is nothing to repair there. The engine is either running or not running. If it does not work, and you know for sure that there is no other reason for this, then it needs to be replaced.

Such a "trifle" as winding a thread on a bobbin often creates a lot of inconvenience. For some reason, it is not always possible to do this quickly and "without problems". Let's see why it is sometimes difficult to wind the thread on a bobbin and what needs to be done to eliminate minor damage to the winder.

Sometimes, you need to remove the overlock covers and lubricate all rubbing parts inside the case. What you need to pay attention to and how to do it yourself.

The owners of Janome sewing machines know firsthand about the excellent quality of this sewing equipment and have personally convinced of this from their own experience. Although sometimes you still have to make minor repairs to the Janome sewing machine with your own hands, which consists in replacing the needle or adjusting some of the unit's components for more correct and accurate operation. But not a single type of mechanical equipment is insured against wear or complete failure of some parts, and even more so equipment with electronic filling.

Needless to say that if any breakdown occurs in sewing machine Janome, the most correct solution would be to call the master at home or transport the sewing machine to a service center to correctly determine the cause of the breakdown and effectively eliminate it. The subsequent reliability of the functioning of the sewing machine directly depends on the professionally carried out repairs and settings of the sewing equipment.

The feasibility of self-repairing a Janome sewing machine directly depends on the complexity of the breakdown, confidence in the accurate diagnosis of the cause of the problem, and the ability to fix it. For example, if a needle breaks in your sewing machine, then it is quite possible to replace it on your own, but if the sewing equipment becomes unstable or stops turning on altogether, in this case, it is better not even to try to fix something yourself, since this can finally break sewing machine, without the possibility of subsequent recovery.
