The site has a lot of articles on the repair of sewing machines. However, first of all, these articles are of an informative nature, intended not for amateur craftsmen, but for owners of sewing machines.
From them you will learn how this or that sewing machine is arranged, what breakdowns it can have if the operating instructions are not followed. And finally, how to perform a simple repair of a sewing machine with your own hands, if it is not possible to contact 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 breakdowns do they have and whether it can be repaired on their own.

1. Janome sewing machine with oscillating 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 you can buy in the range of 4-5 thousand. They are quite reliable and "hardy", but there are limits to everything, and after that, when it was on this machine (photo) that they 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 nose approaches the needle, the eye of the needle is too high and therefore no stitches are formed. This is a very common failure. In quotation marks because such a failure occurs when the operating rules of any sewing machine are not followed, and Janome is no exception. This is not even a breakdown, but a violation of the interaction parameters of the shuttle mechanism and the needle. It happens at the moment of excessive load. And the execution of the finishing line on the hem of jeans is just that case. The toothed belt connecting the upper and lower shaft "skips a tooth" and the machine stops making stitches, although it still works fine. 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 cannot be hemmed on household sewing machines, count how many layers of fabric are formed at the roughest point (the junction of the seams). From 9 - to 12 layers. Take a needle and try to pierce such an area with a hand needle, it is unlikely to succeed. Only if the needle is hammered.

But let's get back to our Janome sewing machine 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, the thread breaks, then look at how the shuttle nose interacts with the needle.
Detach the presser foot, needle plate. Lay the machine on its side and remove the upper part of the shuttle so that the hook remains in its grooves and is not skewed. Now gently turn the handwheel and bring the hook nose up to the needle. If you find such a "picture" as in this photo, then the cause of the malfunction is different and the machine does not need to be disassembled. The photo shows that the nose of the shuttle fits, as it should be, 1.5-2 mm above the eye of the needle. If the spout is below the ear or flush with it, then you will have to disassemble the body of the machine in order to have access to the node we need.

I do not recommend disassembling modern sewing machines. There is nothing complicated about this, but only for someone who knows how to do it right. In any other case, there is always a desire to use a nail puller. Well, like all the screws are unscrewed, but the case is not disconnected. 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 halves of the body. First you need to carefully study them, find them. For example, several pieces may be under the front cover, in the tensioner area upper thread, hook mechanism (remove the needle plate).
Further, some of them "hide" under the plugs, which are 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 types of stitches. By the way, do not forget about the reverse lever when you assemble the body back. 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 left, then you passed the attentiveness test by 5 points.

4. The device of the Janome sewing machine

If you are going to buy an inexpensive Janome sewing machine, you can look at these photos that demonstrate its design well. This will help you make right choice.
IN next paragraph you will find out the cause of the malfunction of this sewing machine.

If the copier is "dry", its grooves must be lubricated with grease.

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

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

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

The cause of the malfunction was in this node, marked with an arrow. And it didn't take long to find out. Toothed beltconnecting the main shaft to the lower shaft, this model of the Janome sewing machine did not have. 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 jeans, the eccentric mounted 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, the line did not form. The fastening of this eccentric is inside (arrow).
After setting the correct parameters for the interaction of the needle and the nose of the shuttle and then tightening the fastening of the eccentric (screw), the breakdown was eliminated.

Sewing machines from Janome (Janome) have many various models designed for different categories of buyers. There are a number of economical sewing machines, affordable and designed for small tailoring and repairing clothes at home.

The famous Japanese brand Janome is famous for its excellent quality. More than 300 models of sewing machines are produced alone. About a hundred countries have active contracts for the supply of Janome sewing machines.

By this indicator, one can judge the quality of manufactured products. Every day, thousands of machines leave the assembly lines of enterprises, and the stable demand for them confirms the amazing manufacturability and functionality of the devices. In addition to ready-made machines, 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 with them. The main reasons for them are negligence in the performance of work and lack of proper care.

Even the best equipment can be rendered unusable if it is not provided with proper operating conditions. Below we will look at typical breakdowns in which it becomes necessary to repair Janome sewing machines.

2 Caring for your Janome sewing machine

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

If you begin to notice that the machine starts 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 degree of 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 removed for storage. Before this, the Janome sewing machine must be cleaned of dust and lubricated.

Any preventive cleaning and lubrication is accompanied by the removal of the shuttle. After that, with the help of a special brush, all rubbing surfaces are cleaned of lint and fabric residues. Oil is poured into the technological holes. Moving parts are also lubricated.

The places to be lubricated are indicated in the instructions for a particular model. Lubrication should preferably be done no more than once a month, as excessive lubrication can have the opposite effect. Any 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 power, and in your locality there is a service center for Janome sewing machines or just repairing sewing machines, then you can apply for a service there. Otherwise, such preventive measures will have to be carried out independently.

The sewing machine can only be stored in heated rooms with normal humidity. It is unacceptable to leave it in the basement, garage and other rooms in the absence of heating.

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

To learn or at least see 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 the repair of modern household sewing machines. A visual representation of the design of the sewing machine will help you make the right choice when buying it, and will also make you take care of it later.

It is quite difficult to disassemble a modern sewing machine on your own, but in most cases you will not have to do this. But still there are cases when you have to disassemble the sewing machine yourself. For example, when you need to replace the electric drive, a line does not form, the needle breaks, etc., and there is no way to contact the workshop, because it simply does not exist in your city or village.

In this article, you will learn how to properly disassemble (remove) plastic lids a modern household sewing machine, an ordinary inexpensive model from Brother, Janome, and any other.

1. What tools are needed

Almost all models of modern economy-class household machines are assembled in China, and therefore, in order to disconnect the plastic parts of the case, you only need Phillips screwdrivers. One screwdriver should have a Phillips slot for medium-sized screws and one slightly more powerful, even with a flat slot.

Screws for machines of European assembly (sometimes Taiwanese) often have some feature. You can unscrew them only with a special screwdriver (asterisk) with a special slot. First, look at what kind of screwdriver you can unscrew the case mount, you may have to buy it in a store specifically for this.
This photo shows types of modern screwdrivers and screws. By the way, we will disassemble the sewing machine, which is in the foreground. It is called "Dragonfly" - China. Its body is assembled on ordinary cruciform screws.

2. Before disassembling the machine

First, remove all parts that do not require special tools. Start with the removable table, then detach the foot. Remove the needle plate. To do this, with a flat screwdriver, you need to unscrew only one screw (sometimes two). Naturally, you need to pull out the bobbin and the plastic hook or bobbin case, remove the spool and, in order not to get hurt, it does not hurt to remove the needle.
Now you need to unscrew the screw indicated by the arrow in the photo and carefully remove the front cover. There is a special latch at the top of the cover, you need to unfasten it before "pulling it out" by force.

All screws do not need to be put in one "heap". When you start to assemble back, it will be difficult for you to determine which screw and where it was. Therefore, mark them in any way convenient for you. For example, you can put a piece of paper with a mark next to each screw (s).

3. We begin to disassemble the sewing machine

Now let's start disassembling the sewing machine, or rather disconnect its plastic case, consisting of two halves. But first remove the shuttle cover. To do this, unscrew the screws indicated by the arrows. As well as the front cover, this part, in addition to screws, is also attached to the 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 reverse side, where the flywheel is located, remove the stitch selection knob. Just pull it hard to the right. Immediately pay attention to how it stood, so that it is easier to install it back.

And two more types of fastening are located in the lower part of the machine body. For many models of sewing machines, rubber feet in the lower part of the body are also fastening the plastic case to the metal frame of the sewing machine. In any case, for this model of the machine, two rear legs serve as such a mount. But since we will be removing only the front of the case, unscrew only one leg (upper right).

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

4. Unscrew the most inaccessible screw

The last, but most inconspicuous screw (B) remains. It is located in the depth of the front of the machine. Even at high magnification, it is not visible in the photo. That screw, which is so clearly visible, does not need to be unscrewed. This is the top thread tensioner. By the way, it remains in place after removing the cover. Consider this moment and do not try to remove it. Actually, it is not difficult to unscrew the screw itself, 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 approximately the same. Look carefully, your machine may have an additional mount at the bottom of the case. It happens that the fastening of the covers is hidden by plugs. Pry off the plug on the back of the machine with a knife blade and make sure there is no additional fastening there.

By the way, it is with the help of a knife that you will have to remove the cover, since in addition to the screws on the ends of the covers there are latches. Insert the knife blade between the body ladles and carefully try to push them apart by moving the latches. But it’s difficult to immediately determine where they are located, so please be patient if you really decide that you definitely need to disassemble the sewing machine.

5. How to separate the two parts of the body

This is approximately the "picture" you will see when you can disassemble your sewing machine. It is probably worth noting that the most difficult thing is not to find all the screws that secure the covers to the case and to each other. It is very difficult to carefully remove the covers, disconnect their latches. If this is done in a hurry, then you can damage the plastic, which will ruin not only appearance machines, but it will also interfere with work. Rough parts in the area of ​​the sleeve of the machine will cling to fabrics and even form puffs.

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

How does a modern household electric sewing machine work. The main malfunctions of units and mechanisms.

Sometimes it becomes necessary to disassemble the sewing machine, or rather remove the plastic case of the machine in order to gain access to some nodes. This need is very rare and only occurs when the sewing machine motor or drive belt needs to be replaced.

Just like the pedal, the electric motor is not worth repairing yourself. Moreover, there is nothing to repair there. The engine either works or it doesn't. 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 thread on a bobbin often creates a lot of inconvenience. For some reason, it is not always possible to quickly and "without problems" do this. Let's see why it is sometimes difficult to wind the thread on the bobbin and what needs to be done to eliminate minor damage to the winder.

The opinion of the master about which sewing machine is the best. Details about the used Rubin sewing machine and other old Veritas models.

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

The owners of Janome brand sewing machines know firsthand about the excellent quality of this sewing equipment and have personally seen 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 units of the unit for more correct and accurate work. But not a single type of mechanical equipment is insured against wear or complete failure of some spare parts, and even more so equipment with electronic filling.

Needless to say, that in the event of any breakdown in the sewing Janome typewriter, 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 repair and adjustment of the sewing equipment.

Our official service has professionally trained employees and all the necessary modern resources, including tools and original spare parts, to carry out quality repair Janome sewing machines. A large number of people turned to us for help in repairs and were completely satisfied with the quality of the work performed.

The speed and quality of work related to the diagnosis, repair and adjustment of Janome sewing machines;
The service of calling the master to the house, which allows us to significantly save time and money for our customers, and also not to worry about the way the machine is delivered to our service center;
Sufficiently low prices for our services, regardless of the complexity of the breakdown or the model of the Janome sewing machine.

The feasibility of self-repairing a Janome sewing machine directly depends on the complexity of the breakdown, confidence in accurately diagnosing the cause of the problem, and the ability to fix it. For example, if in your sewing machine the needle broke, it is quite possible to replace it on your own, but if the sewing equipment began to work unstable or stopped turning on at all - in this case it is better not to even try to fix something on your own, because this way you can finally break the sewing machine, without the possibility of subsequent recovery performance.

If, without proper knowledge and skills, you try to fix an unknown problem on your own, then there is a high probability of further aggravating the breakdown that has occurred and making its subsequent repair more difficult and expensive. Only a person with experience and sufficient knowledge is able to diagnose the cause of the problem and professionally eliminate it. By contacting our service center, you will receive high-class qualified assistance in repairing Janome sewing machines in the face of our professionally competent craftsmen.
