A household sewing machine is an indispensable assistant for a housewife. This little assistant can handle anything. Hemming trousers or a skirt, hemming the edges of curtains and even embroidering - all this is possible for a housewife if she knows how to use a sewing machine. But, unlike others household appliances, a sewing machine is a very capricious unit, sometimes it just ends up sewing. In order for the device to be a reliable assistant for you, it is useful to know why it does not sew sewing machine. In this article we will analyze all the main malfunctions of such devices and give tips on how to eliminate them.
Main malfunctions of sewing machines:
- The presser foot mechanism does not feed the material or feeds it poorly;
- thread break;
- the needle breaks;
- the fabric does not move;
- shuttle malfunction;
- The drive belt is loose.
The machine does not feed fabric well
This kind of malfunction occurs very often. When the machine operates correctly, the fabric should move without jerking, evenly, at the same speed. If this is not the case, then most likely the fabric feed mechanism is faulty. It happens that the cause of such a breakdown is the fault of the housewife herself, who, to speed up sewing, pulls out the fabric, helping the machine with her hands. As a result, the feed conveyor may malfunction. In addition, pulling the fabric with force can bend or even break the needle.
If the fabric feed mechanism is faulty, you will need to adjust it. The feed dog does not fit tightly enough to the presser foot, causing the fabric to slip. Adjusting the rack is quite a troublesome task, and in this case it is better to contact a professional adjuster. It happens that after prolonged use, the teeth of the feed rack become dull. To avoid this, do not allow the sewing machine to run idle without fabric.
Broken thread
There are a number of reasons why a sewing machine does not sew a stitch and breaks the thread. One of them is incorrect adjustment of the upper thread tension. The thread is simply overtightened and breaks when fed, not having time to follow the needle. To achieve proper operation, you must first completely loosen the upper thread regulator, and then, gradually increasing the tension, ensure that the machine operates correctly so that the thread does not break.
Another reason is a crooked needle. During operation, it may bend and touch the needle plate or the foot that presses the fabric. As a result, the thread catches on the edges and breaks. The Seagull sewing machine is especially susceptible to this. Let’s look at why other machines don’t sew further.
Often the thread can break, oddly enough, due to its quality. Threads for sewing machines and hand sewing or embroideries are noticeably different. For hand sewing - cotton, they have an uneven structure and feel velvety when used. If you put such threads in a sewing machine, they will quickly become frayed and tear. It is important to choose high-quality threads for sewing machines. They are thin and elastic.
The needle breaks
This is also a serious malfunction, due to which the sewing machine does not sew. Why does the needle break? There may also be several reasons. The first of them is the incorrect installation of the needle itself in the needle bar. If it is not inserted all the way, then during operation it may hit the shuttle and will inevitably break. The position of the needle must be constantly checked. If its fastening in the needle bar is loose, then you need to tighten it, after inserting the needle up until it stops.
Often needle breakage occurs due to incorrect selection. If, after sewing thin fabrics, you decide to sew denim fabrics with the same needle, this will inevitably lead to breakage. The needle must be selected according to the thickness and type of fabric. For coarser fabrics, there are special needles that differ in thickness and sharpening. There are also universal needles suitable for all types of fabrics. In addition, needles can break due to poor quality material from which they are made. Don't buy cheap needles from unknown sellers and you can avoid wasting money.
The shuttle is faulty or its adjustment is incorrect
Why doesn't the Podolsk hand sewing machine sew? Most likely this is due to the operation of the shuttle. The quality of these machines often depends on its condition. What malfunctions can there be? Dirt or moisture may get into the shuttle, then it may be difficult to rotate, and in some cases even jam. Because of this, a manual sewing machine does not sew. Why is this happening?
Long downtime of the machine
If you haven't used a sewing machine long time, then moisture may get into the shuttle, which will inevitably lead to corrosion. To avoid this, you need to periodically lubricate the machine, even if it has been idle for a long time. How to do this correctly is written in the instructions for your sewing machine.
It's another matter if dirt gets into the shuttle. This can happen, on the contrary, from long-term and continuous use of the machine. The threads you sew with are not perfectly clean; there may be dirt or dust accumulated on them. Together with the lubricant, all this forms a viscous mass, which clogs the shuttle. To avoid this, periodically the shuttle must be disassembled and cleaned, adding new lubricant.
Drive belt loose
Another reason why a sewing machine does not sew may be a loose drive belt. This can be noticed immediately after you turn on the machine and press the drive pedal. The motor may spin idle, but the machine will not sew. This can be easily fixed without calling a technician. You need to loosen a couple of bolts on the engine mount and move it down a little, checking the belt tension with your hand. Once it is tight, secure the engine in this position. Just remember to turn off the power to the machine before this operation.
If you have old car with a foot drive, the above action will not work. These devices do not have a belt tensioner. In this case, the belt must be removed and shortened by approximately one centimeter. Then fasten it with a bracket and install it back. You need to remember that you can’t overtighten the belt either. This can cause the machine to run rough and lead to pulley failure.
This article provided basic answers to the question of why the sewing machine does not sew. Most breakdowns can be fixed on your own. But for things like fine tuning, it’s best to contact a technician or service center. There is no need to save where you can lose more.
Sewing machine malfunctions can be detected by external signs. For example, skipped stitches appeared or the upper thread began to loop at the bottom, or the sewing machine began to “knock” during operation. Suddenly the fabric began to move poorly or the needle often broke, etc. It is much more difficult to determine the cause of the malfunctions that appear and even more difficult to eliminate them, to repair the sewing machine yourself.
In this video you will learn the reason for the expensive repair of a sewing machine caused by a broken toothed drive belt. You will also learn recommendations on how to avoid this sewing machine breakdown.
To make it easier for you to find a breakdown, we suggest short review the main malfunctions and the reasons for their occurrence, as well as a selection of articles on the site devoted to these issues. But, before you figure out why a sewing machine or overlocker does not sew or sews poorly, you need to make sure that this model of sewing machine is operated in accordance with its technical characteristics, including, exclude the use of materials, fabrics, threads, needles not specified in the passport or manufacturer’s instructions. Let’s also agree that the threading is done correctly and other basic requirements are met, for example, the seamstress does not pull the fabric towards herself with her hand, etc.
1. Sewing machine malfunctions can be grouped into three groups
All emerging malfunctions and malfunctions in the operation of sewing machines can be divided into three main groups: violations of stitch formation; poor quality stitching; malfunctions in the operation of components and mechanisms.
Disturbances in the stitch formation process: skip stitches; stitch length instability; top thread breakage; break bottom thread and etc.
Poor quality stitching: stitch landing; tightening the material in the line; "oblique" line; poor-quality trimming of fabric edges (overlock); poor-quality tightening of threads into a stitch (looping), etc.
Malfunction of machine devices and mechanisms: "heavy" movement of the machine; increased noise during operation; "jamming"; damage to the needle and other parts.
According to these three groups, we will consider possible malfunctions, from the point of view of the reasons for their occurrence, and, accordingly, ways to eliminate them. You can read the entire article, this information will not be superfluous for you. Or you can immediately find the group of reasons you need with detailed recommendations. At the end of each section there is a list of articles, to one degree or another, devoted to these malfunctions. It is important to understand that finding the causes of sewing machine malfunctions is intuitive. Various kinds of recommendations can only be used as a guide to the direction of the search. Experienced master does not use a “smart” book, he relies only on practice.
2. Reasons for violations of stitch formation in a line
Skipped stitches. The most common reason for stitch skipping in any sewing machine is the lack of a “confident” grip of the needle thread loop by the nose of the hook or loopers. Adjusting this parameter of a sewing machine always requires experience, especially with overlockers. The formation of a loop near the eye of the needle occurs when the needle is raised from the lower position by approximately 1.8 - 2.3 mm. The nose of the shuttle or looper should at this moment pass just above the eye of the needle and almost close to the needle blade. Since it is not always possible to perform high-quality settings for these parameters yourself, we only recommend checking them. This will allow you to determine that the cause of the skipped stitches may be due to another problem.
The occurrence of a skip may be influenced by the compensation spring.
Blunt nose of the shuttle.
When the thread number does not match the needle eye size (thread is too thick).
Large (broken) needle plate hole.
For thin fabric The needle used is too thick.
The needle in the needle bar is loose.
The needle is not installed correctly.
The appearance of excessive play in the components and mechanisms of the machine.
Defective needle.
Broken upper and lower thread. The most common causes of thread breakage can be: thread abrasion; cutting thread with sharp edges of parts; thread rupture due to pinching, overlapping, etc. To detect places where the thread breaks, you need to inspect the entire route of the thread (you can use a magnifying glass). Probable reasons thread abrasion can be: roughness of thread guides and surfaces in contact with the thread in the area of its breakage; too much thread tension; decrease in the strength of the thread due to its unwinding.

How does a sewing shuttle work?
Tight stitch. The stitching is pulled together most often due to excessive tension on the top thread and too little pressure of the presser foot on the fabric. First adjust the tension of the lower thread, then set the correct tension of the upper thread. The interweaving of the top and bottom threads of the stitch should be inside the fabric. Adjust the presser foot pressure so that when the presser foot is lowered and the teeth of the feed are raised (the needle is above the presser foot), the fabric can only be pulled out with noticeable force. A rough surface of the presser foot (worn out) can also cause the fabric to pull together in the stitching. The stitching will tighten if the worn teeth of the rack do not advance the fabric well. Therefore, it is not recommended to set the sewing machine in motion with the presser foot down and without fabric.
Fabric tightening. May occur when the fabric motor and needle malfunction. It is difficult to adjust such a breakdown on your own, but you can check it. The teeth of the rack should completely lower ("hide") at the moment when the needle almost approaches the needle plate (1.5 -2.0 mm).
Poor quality cutting of fabric with overlocker. Dull overlock knives do not cut fabric well, which leads to gaps and permanent stitch tightening. A characteristic dull knock when the overlocker is operating indicates that the knives and needle have become dull.
Poor quality stitching. The so-called “loop”, as well as oblique stitching, is formed due to excess top thread. As a rule, the reason for this is the appearance of roughness along the path of the upper thread or a violation of the shuttle stroke settings (Chaika sewing machine). See also:

4. Malfunction of the components and mechanisms of the sewing machine
Heavy running of the sewing machine. Most often this is caused by a lack of lubrication, clogging of the shuttle mechanism with tow, thread trimmings. Often, heavy running of the machine may occur after replacing the electric drive belt. A belt that is too tight makes it difficult for the sewing machine to rotate easily and contributes to noise from the parts during operation. Excessive tightening of fasteners and connections of machine parts also makes it difficult for them to rotate.
The sewing machine jams. Sewing machine jamming can occur after long-term storage of the machine. If the machine has not been used for a long time, it is recommended to lubricate it first, and then operate the sewing machine without thread for several minutes. Using the wrong oil will also cause the sewing machine mechanisms to jam. Some types of oils can dry out over time, especially when high temperature air. They turn from oil into glue, which most often becomes noticeable after a long period of “downtime”. Rarely, parts can break down, leading to malfunction of the machine.
Needle breakage. Needle breakage usually occurs due to inept seamstress work. The fabric should not be pulled towards you by hand. Correctly adjust the presser foot pressure on the fabric and the lifting height of the dog teeth, and you will no longer need to “help” the machine with your hand. When sewing coarse fabrics, a needle that is too thin is used. A needle is used that is not intended for this model of sewing machine. The needle is not inserted into the needle bar all the way. The needle is not centered on the plate's needle hole. See also:

Such a “trifle” as winding thread on a bobbin often creates a lot of inconvenience when sewing. For some reason, it is not always possible to do this quickly and “without problems.” Let's figure out why it is sometimes difficult to wind thread onto a bobbin and what needs to be done to fix minor damage to the winder.
It's rare, but sometimes you can find foot-operated machines. The best solution, instead of repairing the foot drive, is to install an electric drive on the machine. This is not difficult to do and anyone with a screwdriver can install it with their own hands. But, if you still need recommendations on how to repair or adjust the foot drive, this article is at your service.
The main malfunctions and malfunctions of these sewing machines, as a rule, are not related to its adjustment. Sometimes it is enough to install the needle correctly, replace low-quality threads, select the correct tension of the lower and upper threads, and the machine will work perfectly again.
If the foot drive is, one might say, a complete antique, then the manual drive can be used, especially for beginners learning to sew. Read this article to learn how to repair this device yourself.
Sewing machine faults and problems It will be easier to fix if you understand how the sewing machine works and which part is used for what. Study carefully the structure of your machine according to the instructions or using our article.
Why did a modern household sewing machine suddenly start skipping stitches? The sewing machine repairman explains.
The machine doesn't sew
The machine may stop sewing due to prolonged continuous use. You need to let it sit for a while, “rest”, and then you can start sewing again.
Strange sounds and machine stopping
A common cause of this problem is a needle stuck in the fabric, which, in turn, is not suitable for the selected fabric. The needle should be replaced according to the type of fabric.
Make sure the needle is not broken or blunt. If we used to sew very thick fabrics or we forced them, sometimes the needle suffers from the impact and breaks. Well, it's simple, run your finger along the tip of the needle and if the tip is soft, that tells us that the needle is perfect. If, on the other hand, you notice any protrusion or shampoo, it is blunt or the tip has been bent. In this case, replace it with another one immediately because if you stitch the needle in this condition, you may hit the ruler or needle plate and damage those areas.
Insert the bobbin into the bobbin by passing the thread through the notch it has. This will cause the bobbin thread to be tight and stitched correctly. Insert the canister into the shuttle until you hear a click. Remember that if you are going to sew many layers of fabrics or thick fabrics, choose a long stitch, which is number 4, and if you are going to sew very thin fabric, use number.
The needle doesn't move
In this case, the thread is not threaded correctly, the presser foot is not lowered correctly, or the thread spool has slipped (or is positioned incorrectly).
The upper thread breaks
The upper thread breaks if it is not inserted correctly. A knot may form on the thread.
Don't forget the presser foot. Don't forget to use a universal presser foot if you are going to sew straight and normal. To start sewing, place the fabric half a cent from the beginning of it. Sometimes if we start stitching fabric to fabric, it gets stuck and creates a little wrinkle.
That the Industrial Revolution gave women the power of privacy in their homes. Maines talked about the vibrator, but much more early history prepared a terrible prank for women: sewing machines as an orgasmic element. How a sewing machine can become an object sexual pleasure? The answer has to do with the position of women in society not so long ago.
High thread tension
The needle is incorrectly selected for this type of fabric.
Poor quality thread
A bent needle is inserted into the machine. The lower thread breaks.
Broken thread in bobbin
In this case, you should check whether the bobbin is inserted correctly into the hook. The thread is wound unevenly on the bobbin.
The main problems of a sewing machine and the reasons for their occurrence
First there was a sewing machine
You may have never thought about it, but before sewing machines were ripped apart, all clothing was made by hand. Obviously this meant that many people worked in very poor conditions for very little money. In fact, both before and today there is a curious circumstance; fashion, that concept that is supposed to reflect society and its culture, the advancement of the times, has very little in common with the majority of those who make it possible, often from everything that "fashion" allows.
For example, the textile boom was a real liberation for women who left home and joined the workforce. Although, if anything really changed this phase of the working woman in this sector, it was undoubtedly the advent of the sewing machine.
Fabric doesn't move
The fabric is too thick or stuck.
The fabric conveyor is full of threads
You need to remove the foot and clean the conveyor using a toothbrush. Check whether the needle is inserted correctly. There may be a problem with the stitch length dial.
The thread gets caught in loops under the fabric
It is necessary to check the correct position of the upper thread and the thread in the bobbin. It's best to rethread the thread. The bobbin may be damaged and should be replaced.
Because even though it sounds awkward, back then they had to prove it. And it's all thanks to a guy named Elias Howe. Elias was an inventor from Massachusetts who worked as an apprentice in a textile mill. After the factory closed, he moved to Cambridge to work as a mechanic, where he specialized in the manufacture of precision instruments such as chronometers.
Woman and using a sewing machine
The truth is that Howe thought there had to be another way to make clothes. His invention went into mass production and quickly revolutionized clothing production. The decade after Howe's invention was a time of great improvements in the machine. The inventor was followed by others such as Isaac Singer, whose last name became the most recognizable company in the market. With their advent, a new industry of sewing machines emerged, which began to be sold in the millions with the emergence of dozens of new manufacturers.
Skipping stitches
It is necessary to check the thread tension. Adjust the tension of the upper and lower threads: it should be the same. Check that the machine is threaded correctly and is positioned in the bobbin. You should check the needle: it may be bent or incorrectly positioned. Remember that the needle must match the thickness of the fabric.
The first beneficiary was the textile sector and garment factories, which until recently had to be operated by hand. The woman was freed from the slavery of the needle. The sewing machine embodied a new era that made life easier for women. So much so that for some this happiness turned out to be excessive.
It happens that technology has made work easier, but it has also brought new problems in their lives. Many complained of ailments such as fatigue, back pain from the new position at work, and even hemorrhages. What's happened? That some doctors, all men of the companies, agreed on the diagnosis of such diseases.
Uneven stitches
You need to loosen the thread tension. The lower and upper threads are selected of the same density and good quality. You can refill the machine. Check the correct placement of the thread in the bobbin and the bobbin itself.
Wrinkled seams
Check thread tension. It is likely that a thick needle is used for too thin fabric. Do not pull the fabric too much when stitching.
It was not the long days of work, nor the pace of production, nor the conditions of the factories. The reason women are tired is female masturbation. Although it sounds like a joke, the truth is that doctors diagnosed overstimulation as what ultimately caused the health problems they suffered. For us to understand, the debate that doctors opened revolved around the possible abuse of the machines, since the rhythmic pumping of the thighs was sexual arousal. In short: with these guys in mind, women were stimulating themselves with machines.
The machine is jammed
You should cut the thread and remove the fabric, remove the thread from the machine. Remove the bobbin and clear the threads, then re-thread the machine and you can continue sewing.
Now you know why the sewing machine does not work.
First of all, we will answer you what a sewing machine is. First of all, this is a complex mechanism created to perform various operations when sewing - overcasting, stitching, etc. And if a failure occurs in some unit for any reason, then the entire mechanism begins to work poorly. IN otherwise the sewing machine may simply break down, after which it will need repairs. And this is money and time. But in this article we will tell you about those problems that you can handle on your own.
In it they place insomnia, fainting, headaches, heaviness in the same bag. abdominal cavity or muscle spasms. Women diagnosed with the condition were told they should receive a treatment known as "pelvic massage" until they achieved orgasm. In other words, there was a time when sexual desire women were considered a disease. They say that thanks to this illness, Freud began to discover the unconscious. Even along the way, the first mechanical vibrator appeared with the aim of providing such massages.
Therefore, and in the context of history, when there were doctors who prescribed doses of vibration to relieve symptoms, textile industry executives and doctors who were part of every company tried to curb this supposed stimulant in which the sewing machines turned.
The needle is something that most people don't pay attention to.
A lot depends on the needle that is in the sewing machine. Its size, surface quality and groove affect the quality of the stitching. The needle must match the thread and material. For example, a sewing machine should not have a thin needle installed, but a thick thread should be threaded. and vice versa. The thread should almost completely fill the long groove in the needle and not protrude outward. Otherwise, the needle will simply tear your thread. The needle in a sewing machine should be sharp and even. If it becomes dull, then without hesitation, replace it with a new one. Insert the needle all the way and be sure to securely secure it with the fastening screw.
According to Dr. Langdon Down, who was hired by one of the companies, the fault was in the pedal. When it was activated, it caused excessive blood flow in the lower regions causing stimulation. Down ensured that they could reach orgasm. Perhaps sadder than the doctor's own statement was that there was a moral time behind everything. Doctors saw that this machine could threaten women's physical health and their moral health, even by encouraging certain "habits."
Finally, there was no consensus, and the disadvantages were shared between machines and women, who at that time not only had to feel ashamed because their work could give them supposed pleasure, but they had to deal with the control exercised by man over his own bodies during several decades.
If a needle in a sewing machine breaks, then most likely it was either crooked. Because of this, the needle did not enter the hole in the plate, but hit its surface. If the needle does not pierce the layer of material, breaks or bends (especially at the seams), then pay attention to how you pull out the fabric. It happens that the thread jumps out from under the foot of the sewing machine and bends the needle. But if the needle starts to hit the shuttle device, then call a mechanic. You can't do it on your own!
Do you like to wear and feel very comfortable in knitted clothes? I love a lightweight neoprene t-shirt or even pants! Analyze your clothes. Have you noticed that the meshes are only covered with overlock? Finishing is done in the galley. What do you do when you don't have these two cars?
To sew mesh on a straight machine, it is important to use a ballpoint needle that has a gold tip. The package says "mesh". This needle, as already mentioned, has a rounded tip so as not to pierce the fabric and “break” the elastic threads. He slides between the threads until he breaks through them.
If the sewing machine does not advance the fabric well
This can happen due to several reasons:
1. You have not adjusted the presser foot pressure. Or it has simply weakened over time. You just need to increase the pressure, the regulator of which on all machines is located in the upper left part. If there is a pin there, then press it down, if there is a regulator there, then twist it.
It is also interesting to use overlock wire in the machine's bobbin thread, as this wire provides a certain elasticity to a point. As the mesh stretches and snaps back into place, the stitch may snap with the movement if it is not made with that thread underneath. Fill the coil normally, in the machine itself.
You can use polyester or cotton thread on the needle. The point that will be used is the zigzag because its design gives more elasticity to the movement of the elastic mesh. For heavier cells, you can place a straight reinforcement point on each side of the zigzag.
2. The feed teeth are lowered. Or they protrude too little above the needle plate. To correct this problem, check the conveyor lift adjuster. It is quite possible that you simply turned it off. In addition, the conveyor fastenings may have become loose. In this case, tighten the screws located under the needle plate.
Finishing can be done using double needle to simulate a galley. Leave the overlock wire on the bobbin in the same way. If necessary, you can replace the sewing leg from common seams with a plastic sewing leg. In this way, the mesh moves further into the machine. Another option is to attach the durex to a regular presser foot. This will also help with gliding.
Here are some parts of a sewing machine
Remember not to stretch the mesh when sewing. Any questions, leave them in the comments. → Link to the singer's sewing assistant. You will find - next to the product and machine information - also very picturesque tutorials on how. Bobbin winding; inserting a bobbin, threading a sewing machine, winding thread onto a bobbin, choosing a stitch, adjusting the stitch length, adjusting the stitch width, adjusting the tension of the upper thread, replacing the needle, replacing the presser foot. There is also a how-to overview that explains the different sewing machine accessories.
3. The feed teeth are clogged with scraps of fabric pushing against the needle plate. Remove the plastic and clean the conveyor with a thin object.
If you get a bad line out
Oblique ugly stitches, bad stitching... This cannot make anyone happy! Typically, bias stitches are caused by loosening of the screws that secure the feed dog. The thread threaded into the sewing machine is also to blame for this. Try replacing it. Weak or tight stitching can occur due to misadjustment of the machine. If you get loops on the underside of the fabric while working, check the upper thread. Most likely she is weakened. Conversely, if loops appear on the upper surface of the fabric, check the tension of the lower thread.
They often handle errors that cause the sewing machine to fail. With the links below you will find a list of the most common processing errors: Error Handling. First, read how your sewing machine is used and see what the manufacturer recommends and most uses for it.
On vertical bobbin machine
You can clean the outside of the machine with a slightly damp microfiber cloth. Never use wet wipes, as water may damage your device. After 3 hours of seaming, clean the bobbin case using the small brush supplied with the machine. Open the hatch behind which the reel is located and remove the housing by pulling the tab towards you. Secure an old nylon stocking over the hose of your vacuum cleaner or use a narrower accessory to avoid accidentally picking up small machine parts. You can also use a fine spray of compressed air to blow the fabric fragments out of the casing. Under the needle plate of the vertical bobbin machine, many pieces of fabric may accumulate. Clean it with a compressed air spray or vacuum on which you have stretched the nylon stocking.
If your machine has a horizontal bobbin case
You can use a compressed air sprayer or a vacuum cleaner with a nylon stocking on it. Pour in a small drop of special oil for sewing machines where metal parts move close to each other. Rotate the machine slightly to distribute the oil. Then wipe off excess oil. Line up a few stitches on the absorbent fabric to distribute the oil well. The first dots can deposit soil onto the fabric. Are you using very thin or expensive fabric? Pin something else before you start.Knitting, stretch fabric or knitwear are not the easiest materials to work with.
- Before you begin, disconnect the device by removing the plug.
- Remove the upper thread and bobbin thread.
- Clean the case with a cotton swab.
- Disassemble the rest of the bobbin and clean each part with a cotton swab.
- Unscrew the plate and remove it.
- If necessary, clean the plate and screw it into place.
- Remove the presser foot and needle.
- Unscrew the needle and remove it.
- Remove dirt and dust from the hook.
- Place the assembly together.
- After 3 to 5 hours of sewing, clean the threads and threads of the bobbin case.
- They also cause oil to drain from your car.
- Use the special brush that came with your machine.

If your sewing machine skips stitches
If your machine is skipping stitches, the first thing you should check is the needle. It should not be crooked, rusty or dull. Try changing it. Buy a suitable needle (for jeans, artificial leather, knitwear), since it depends a lot on it. If you are working with polished or silk threads and end up with skipped stitches, then before replacing the thread, try simply turning the machine spool over. If you've tried everything but still don't get it desired result, then contact a repair company. Most likely, the breakdown occurred in the sewing machine itself.
If the sewing machine breaks the threads
Most often this happens because the thread is too tight. In addition, the reason may be the low quality of the threads. It happens that a sewing machine breaks threads due to the sharp edges of the thread guide or needle hole. If everything is normal, then check how the thread is threaded. Maybe she's just confused. If, at the moment the needle leaves the hole, the upper thread breaks, then most likely the reason lies in the shuttle device. A repair organization can handle such a breakdown of a sewing machine.
Slow running of the sewing machine
To keep the machine easy to operate and not rattle, simply lubricate it approximately every nine hours of operation. By the way, some modern sewing machines (for example, PFAFF machines) are lubricated only by an experienced specialist. You can only process the shuttle device.
