The Seagull sewing machine is perhaps the most popular model of a home sewing machine, despite the abundance of imported household sewing machines in stores. At one time, I had to buy it for a lot of money, and it seemed like she sewed well recently, only something began to wind.
It's almost impossible for her to break. The body is made of aluminum, the parts are all metal, the components are strong and reliable - everything is in the style of Soviet technology. But, unfortunately, it winds practically "from birth" and knocks when sewing, like a machine gun.
Many other "charms" were provided by the factory along with instructions for the device and use, where almost 5 pages describe how the pedal is arranged, the electrical circuit of the engine is given, but not a word about how to set up and repair Seagull sewing machine.
Model range of sewing machines Chaika
The Seagull sewing machine has many models that differ little from each other: Seagull 2; 3; 142m; 132; 134; 143 and others. Sewing machines of the Podolsk plant: Podolsk 142, Podolsk 125-1; Malva have about the same device as the Seagull. Therefore, the instructions for one of these machines are quite suitable for any model of a Seagull-type sewing machine.
Setting up, adjusting and repairing Seagull sewing machines is almost the same for all models mentioned above, with the exception of copier repair (depending on the machine model) and setting some shuttle parameters.
But since our task is to learn how to tune only the line, we will omit the repair of many nodes in this article. In addition, such repairs cannot be done with your own hands, without professional knowledge and experience, and even at home.
Repair of the sewing machine Seagull
The main malfunction of machines of the "Seagull" type, performing a zigzag stitch and several types of finishing stitches based on it, are skips, looping of the lower and upper threads, as well as thread breakage from above and below. It is these faults and how to fix them that we will consider in this article. 
Before proceeding with the repair and adjustment Seagull sewing machine with your own hands, it is advisable to do a routine inspection, cleaning, lubrication. To do this, disconnect the electric motor from the mains, remove the top cover (it is fastened with two screws on top). Detach the presser foot, remove the needle and needle plate, bobbin cover. Detach the machine from the wooden stand or table. Disassemble the shuttle: bobbin case, locking ring, shuttle. Now remove dust, dirt, lint from the machine (especially in the shuttle compartment) and lubricate all rubbing, accessible places well with machine oil. You can look at the places that need to be lubricated in the instructions for the machine or lubricate all available rubbing metal parts and assemblies.
It is very convenient to use a medical disposable syringe for lubrication.
Thread breakage most often occurs with Chaika-type sewing machines.
The first reason leading to thread breakage is the bent point of a blunt needle, which breaks the thread during its movement. With the help of a magnifying glass, the state of the needle point is very clearly visible.
Shuttle adjustment of the Chaika sewing machine
Shuttle position incorrect sewing machines Seagull leads to thread breakage and the appearance of other stitching defects, including gaps. Passes usually appear due to the wrong position of the shuttle at the moment of meeting with the needle - the nose of the shuttle does not capture the loop formed, passes by and a gap is formed. Many other factors can be the reason. 
In order to correctly set the position of the meeting of the nose of the shuttle and the needle, it is necessary to adjust the position of the shuttle. You can loosen the two bolts that secure it and gently, using a powerful screwdriver, move or move away the move along with the shuttle in relation to the needle. The shuttle travel rotates on an axle rather than moving back and forth. This is very important point. No need to pull it out with a nail puller or hammer it in with a hammer, it easily turns on its axis. It is difficult for an inexperienced person to immediately understand what is at stake, but it is also very difficult to explain in more detail. All that can be added is to carefully figure it out before you twist something, and even more so unscrew it. There should be no remaining parts after repair.
Shuttle and needle adjustment parameters (Seagull)
At the time of the meeting of the nose of the shuttle and the blade of the needle, the following parameters must be observed: the gap between the nose and the blade is approximately 0.15 mm; when the needle leaves the lower position to a height of 1.8-2.0 mm, the nose should approach it above the eye of the needle by 1 mm, at least, but not more than 3 mm.
By the way, a very important point is the lifting of the needle from the lower position (1.8-2.0 mm). This parameter affects the formation of the needle loop and should be given special attention. In order for the spout to grab the thread from the needle, it is necessary that a loop is formed, where it passes, hooking it. That is why the needle must first go down and then, having risen a little, already meet the looper nose.
The position of the needle is also regulated by the needle bar, for this there is a screw for attaching it to the sleeve under the front cover.
If you set such parameters for adjusting the shuttle, then sewing machine "Seagull" will work relatively well. But, unfortunately, this repair is not over. There are still many other shuttle settings that are quite complex and necessary for the Chaika sewing machine. It is there that the reasons for the looping of the thread and such a rare phenomenon for sewing machines are hidden - the breakage of the lower thread. The complexity of the presentation of this material is that for almost any model of the Chaika sewing machine, engineers have provided their own settings for this unit and, moreover, requiring great experience from the performer. For which I thank them, at least from the sewing machine repairmen - they will not be left without work as long as there are Chaika sewing machines.
The Seagull sewing machine performs a straight line, a zigzag line and, based on it, several types of finishing lines. In our time, you can buy such a machine only with an electric drive (with a pedal), a foot model (with a belt), the so-called "cabinet", was produced in Soviet times.
Sewing machine Seagull 2; 3; 142m; 132; 134; 143; Podolsk 142, Podolsk 125-1; Malva and others - all these machines have the same device and instructions for use and setup. They have practically no structural differences, except that there is an additional set of types of decorative zigzag stitches. True, when repairs and adjustments are being made, for each model of the Chaika or Podolsk sewing machine, it is required to know the corresponding parameters, the configuration schemes for the shuttle assembly of each model. This is one of the shortcomings, but the big advantage is that the price of spare parts, especially used ones for Chaika-type sewing machines, is quite acceptable.
Before you start setting up the Chaika sewing machine on your own, it is advisable to do a routine inspection, cleaning, lubrication. To do this, disconnect the electric motor from the mains, remove the top cover (it is fastened with two screws). Detach the presser foot, remove the needle and needle plate, bobbin cover. Detach the machine from the wooden stand or table. Disassemble the shuttle: bobbin case, locking ring, shuttle. Now remove dust, dirt, lint from the machine (especially in the shuttle compartment) and lubricate all rubbing, accessible places well with machine oil.
As a rule, the main malfunctions of Chaika-type sewing machines are thread breakage during sewing; skipped stitches; looping of the upper thread in the line. There is also a characteristic knock during operation, but this is a design feature of these machines and the only remedy is periodic lubrication. Although there are exceptions, and Seagull sewing machines work quite softly.
Thread break. The first reason leading to thread breakage is the bent point of a blunt needle, which breaks the thread during its movement. With the help of a magnifying glass, the state of the needle point is very clearly visible. Use serviceable needles and designed for Chaika sewing machines, in accordance with the instructions.
The question is often asked: how to insert a thread into a needle in a Seagull sewing machine? For all Chaika-type machines, and for most others that perform a zigzag stitch, the needle is placed with the sawn-off part of the flask away from you, and the groove for the thread should look at you. It is from the side of this groove that the thread is inserted.
If the needle touches it when entering the needle hole, then periodically the thread will break. When performing a straight stitch, the needle should be located in the center of the hole in the needle plate, evenly removed from its sides, and when performing a zigzag operation, the distance L should be the same with R. The longitudinal installation of the needle in the center of the needle gap is carried out by shifting the needle bar frame, fixed with two screws on the rocker located at the top of the machine (turn the flywheel on the zigzag line and you will see this mount). Loosen these screws and set the needle exactly in the center on a straight stitch (offsetting the needle bar frame).
Then check the position of the needle for the left and right injection. I hope that the needle entry (at the maximum zigzag width on the right and left) will be evenly removed from the center. If the needle touches the edge of the hole at the maximum width of the zigzag, then contact the master, this case is already for him.
The transverse position of the needle is regulated by a rod fixed on a plate with two screws, and a plate pressing the needle bar frame to the bracket rod. Adjusting this assembly is quite complicated and requires experience, but, unfortunately, it is this mechanism that can spontaneously go astray during operation, especially the Chaika electric sewing machine. Therefore, if you decide to repair your sewing machine yourself, you should learn how to adjust the position of the needle, since moving it forward is the cause of its breakdown, and moving towards the seamstress is the cause of skipped stitches in the line.
Adjusting the needle position requires professional knowledge and experience. If you are not sure that you can do it yourself, contact the master, as it may cause misalignment of other components, the repair of which cannot be learned from a boring book stuffed with technical terms and diagrams.
It can be added that when using a curved needle, notches may form on the nose of the hook, which “unwind” the thread and break. It should be perfectly smooth and sharp, without roughness. Its condition can be determined by running a fingernail along the edge of the spout or using a magnifying glass.
The pressure plate tightening screw must not be serrated, the latch handle must be clearly fixed and its surface must be clean and smooth.
Incorrect position of the shuttle nose of Chaika sewing machines leads to thread breakage and the appearance of other stitching defects, including skips. Passes usually appear due to the wrong position of the shuttle at the moment of meeting with the needle. The nose of the shuttle does not capture the loop formed, passes by and a gap is formed. Many other factors can be the reason.
Overlock class 51 is perhaps the most common brand of industrial sewing machine used in everyday life, in small studios.
It is not always necessary to repair overlocks or adjust them, sometimes it is enough just to adjust the thread tension and it will again overcast the fabric with high quality.
Among the Soviet sewing machines, the most popular are those made in Podolsk, at a mechanical plant. The sewing machine "Seagull" is a favorite assistant of our craftswomen. She has earned a lot of trust. This device is reliable and easy to operate. It has a strong aluminum body, "takes" any fabric and is unpretentious in work.
Sewing machine "Seagull". We eliminate breakdowns
The sewing machine "Seagull" can serve its mistress for several decades. The main thing is to pay attention to damage in a timely manner, be able to eliminate them and periodically lubricate the mechanisms. The model range of devices is quite wide: this is the Chaika sewing machine -134, 132, 132 M, 142 M, 143 and others. Despite the diversity of species, operation and repair is carried out for almost all types in the same way.
Possible breakdowns of the "Seagull" and how to eliminate them
1. When working, the device skips stitches. To eliminate this problem, it is necessary to check the condition of the needle - it should be even and not bent. It is necessary to inspect the needle before starting work, feeling it with your hand. In case of irregularities, it must be replaced with a new one. In this case, it should be borne in mind that only the needle that is suitable for a particular model of a sewing machine is used. The next step is to check if the needle enters the plate that is under it correctly. You can return the needle to its place by shifting the needle bar frame. Another reason for skipping stitches is incorrect placement of the shuttle when it hits the needle. If it is installed incorrectly, then during operation it will slip past without falling into the loop. To fix the problem, the shuttle must be corrected.
2. The needle breaks while sewing. This happens due to the incorrect location of the carriage cone. To repair the Chaika sewing machine, you need to remove the plywood on the side of the device. On the left is the shuttle mechanism, where the carriage is arranged. It is necessary to release it from the latch and turn the flywheel towards you. The pointy top of the carriage should be slightly above the eye of the needle and follow next to it. For the correct location, unscrew the two bolts on the axis of rotation of the carriage and carefully move it towards the needle.
3. Stitch defects when stitching. The sewing machine "Seagull" can give a weak or tight thread when working. The thread is adjusted with a screw. To do this, it must be tightened or loosened by turning it clockwise or vice versa. If this does not help, then you need to remove the plate on which the screw is attached, and bend it slightly inward. Other causes of weak stitching may be a broken upper thread tension knob or a loose nut. To fix this problem, you need to open the cover near the regulator and tighten the nut.
4. When the machine is running, the thread breaks. It is necessary to check the needle plate: it can be deformed, have punctures and bumps. The carriage may also have burrs. The entire marriage is removed by grinding with sandpaper.
The sewing machine "Seagull" in many cases is repaired at home, but if the breakdown is serious, you should seek help from the master.
The proposed instruction for sewing machines Chaika and Podolsk is a simplified version of the manufacturer's instruction manual. This universal instruction can be used for all models of sewing machines Chaika 2, 3, 132, 132m, 134, and Podolsk 142, 142m, Malva and other models.
1. Main components and mechanisms
Remove the top cover (two screws on the top of the cover) and apply a few drops of oil to the main components of the front compartment. Screw 1 is for adjusting the needle bar into which the needle is inserted. Screw 2 clamps the upper thread tensioner. This mount often needs to be tightened, since the plastic body of the tensioner falls through the screw and the tensioner begins to wobble in the seat.
If the fabric does not advance well, most often you just need to raise the teeth of the rail by setting the switch to position (H) - normal, B - embroidery.
When removing the flywheel, be sure to pay attention to the position of the friction washer tabs (L). To completely loosen the friction screw holding the flywheel, loosen the screw (K). Adjusting the tension of the electric drive belt or is carried out after loosening the screw (B).
The bobbin winder also needs to be lubricated and sometimes adjusted.
2. Incorrectly selected needle number leads to thread breakage
Any instruction has recommendations for choosing a needle, depending on the type and thickness of the fabric and the selected threads. Here is a list of recommendations for the sewing machine Chaika, Podolskaya:
Silk, cambric - No. 70; chintz, satin, cambric, linen fabrics - No. 80;
cotton fabrics, coarse calico, flannel, thin woolen fabrics - No. 90;
woolen, costume fabrics - No. 100;
thick woolen fabrics, broadcloth - No. 110.
The needle must be installed up to the stop and tightened well with a screw so that it does not jump out during operation. The flat (sawn) side of the bulb on the needle should be facing away from you. And do not install industrial design needles with a round bulb. Such needles lead to skips and even to serious breakages, in particular breakage of the sewing machine needle.
Before threading the lower thread, you need to turn the handwheel to put the needle in the upper position, pull out the needle plate and grab the latch of the bobbin case with two fingers of your left hand to pull it out of the shuttle of the machine. By the way, when you install it back, a faint click should be heard. If the latch does not work, the bobbin case may turn on the axis and break the needle.
The thread is brought under the spring plate of the cap, which creates tension in the lower thread. The tension is regulated by a screw pressing this plate. By turning the screw to the left, the tension is loosened, and vice versa. Only unscrew no more than half a turn, otherwise the screw may pop out and be lost.
The bottom thread should come out freely without effort, but with a slight perceptible tension. The lower thread tension is rarely adjusted. Basically, it needs to be changed when sewing too thin fabrics or knitwear, as well as when using very thin threads.
4. Control of the sewing machine Chaika, Podolsk
Often the bobbin case of the Seagull sewing machine is called a shuttle or a bobbin. This is wrong, every detail has its own name.
To sew a normal straight stitch, the zigzag width lever must be set to the number "0" and the position of the stitch selection switch should be set to the straight stitch. Set the desired stitch length, usually 3 or 4 mm, thread correctly. The shuttle course consists of a shuttle and a bobbin case. The bobbin with lower thread is inserted into the bobbin case.
Before starting work, check the position of the rack teeth. For sewing medium fabrics, the selector lever should be in the "H" position - normal. "B" - embroidery, that is, the teeth of the rail during the operation of the sewing machine should not come out of the needle plate and not advance the fabric. "SH" - silk, thin fabrics.
The guideline for the correct position of the rack teeth is the position of these letters on top.
To sew a zigzag stitch, set the zigzag width to "0 - 5" and select zigzag on the stitch selector. Do not forget to reduce the stitch length to 1 - 3 mm, otherwise the zigzag will be too sparse.
The tension of the threads when performing a zigzag stitch needs to be adjusted additionally. Adjust the upper thread tension so that both threads are pulled evenly into the fabric. Please note that too much tension on the top thread will cause the fabric to pull when sewing. You may also need to adjust the bobbin thread tension.
The signature sound of the Seagull sewing machine occurs at the knot (L). The bevel gear during operation periodically touches the frame of the machine. Theoretically, knocking can be eliminated, but only the master can do this. However, you can reduce the noise of this assembly yourself if you lubricate the gear teeth with a thick lubricant, such as graphite grease.
Depending on the operating conditions of the sewing machine, lubrication and cleaning should be done periodically, but at least once every six months. Oil for lubrication should only be used special, designed for lubricating sewing machines. Other types of oils can cause heavy running.
Half of sewing machine malfunctions begin due to improper care of the sewing machine. The most common case is when, after a year, the machine is taken out of the pantry and it turns out that it makes passes, breaks the thread, etc. But before there were no complaints about her work. Why this happens, you will learn in the article.
Factory instructions for Chaika contains several pages on how to lubricate the machine. In fact, these recommendations can be simplified and only those places where there is friction of metal parts can be lubricated.
To have access to some nodes, you need to remove the top cover of the machine, reinforced with two screws and the bottom protection (plywood), fixed to the wooden case with 4 petals. Do not get carried away with abundant lubrication, especially around the needle. If you do not want to eventually get an unpleasant oil stain when sewing, then 2-3 drops of oil are enough to lubricate one node in this compartment.
To clean the shuttle and the shuttle compartment, it is convenient to use a hard glue brush, and for lubrication - a regular medical syringe.
This article lists the main malfunctions of sewing machines such as Chaika, Podolsk and how to fix them. Using this material, you can repair sewing machines of other brands, including domestic sewing machines of foreign production, with a vertical shuttle. If you have a manual for a sewing machine, be sure to carefully read the manufacturer's recommendations for the operation and care of the sewing machine.
How is the vertical shuttle. Possible malfunctions and ways to eliminate them. Shuttle of the sewing machine type Seagull.
Basic knowledge of how the sewing machine works and how to set up your sewing machine can be found in the instructions for the sewing machine. If you want to understand in more detail how the sewing machine works, and how to make minor repairs to the Podolsk manual sewing machine on your own, then this article can be your first assistant, where brief instructions for repairing it are given.
Repairing a sewing machine Seagull requires certain knowledge and experience. But, many types of "breakdowns" can be fixed on your own if you read this article. In this article, we offer a concise, simple and plain language instructions for sewing machines such as Chaika, performing a zigzag stitch. The operation and arrangement of the sewing machine Podolsk and Chaika are almost the same. Therefore, this instruction manual can be used for any models of Chaika, Malva, Podolsk sewing machines.
Any instruction for a sewing machine pays considerable attention to the bobbin, small, but important detail sewing machine. How to wind the thread correctly, how to insert the bobbin into the bobbin case, which threads can be used and which bobbins are suitable for your sewing machine model. Read your sewing machine manual carefully. It provides important information that will keep your machine sewing flawlessly for many years to come.
Many have preserved such sewing machines. They have long been outdated, but they are quite suitable for learning the basics of sewing. It is best for a beginner seamstress to use a hand-operated machine. But, as a rule, a manual drive requires serious repairs over many years of operation. How to do this, read this article.
To understand how any lockstitch sewing machine works, first study how a lockstitch is formed. This will give you an idea of which parts of the sewing machine interact with each other to form a quality, skip-free stitch in the line.
The Seagull sewing machine is perhaps the most popular model of a home sewing machine, despite the abundance of imported household sewing machines in stores. At one time, I had to buy it for a lot of money, and it seemed like she sewed well recently, only something began to wind. It's almost impossible for her to break. The body is made of aluminum, the parts are all metal, the components are strong and reliable - everything is in the style of Soviet technology. But, unfortunately, it winds practically "from birth" and knocks when sewing, like a machine gun.
Many other "charms" were provided by the factory along with instructions for the device and use, where almost 5 pages describe how the pedal is arranged, the electrical circuit of the engine is given, but not a word about how to set up and repair Seagull sewing machine.
The Seagull sewing machine has many models that differ little from each other: Seagull 2; 3; 142m; 132; 134; 143 and others. Sewing machines of the Podolsk plant: Podolsk 142, Podolsk 125-1 others, as well as the Malva sewing machine, have approximately the same device as Chaika. Therefore, the instructions for one of these machines are quite suitable for any model of a full zigzag sewing machine, such as Chaika.
Setting up, adjusting and repairing Seagull sewing machines is almost the same for all models mentioned above, with the exception of copier repair (depending on the machine model) and setting some shuttle parameters. But since our task is to learn how to tune only the line, we will omit the repair of many nodes in this article. In addition, such repairs cannot be done with your own hands, without professional knowledge and experience, and even at home.
Sewing machine lubrication Seagull
Before proceeding with the repair and adjustment of the Chaika sewing machine with your own hands, it is advisable to do a routine inspection, cleaning, lubrication. To do this, disconnect the electric motor from the mains, remove the top cover (it is fastened with two screws on top). Detach the presser foot, remove the needle and needle plate, bobbin cover. Detach the machine from the wooden stand or table. Disassemble the shuttle: bobbin case, locking ring, shuttle. Now remove dust, dirt, lint from the machine (especially in the shuttle compartment) and lubricate all rubbing, accessible places well with machine oil. You can look at the places that need to be lubricated in the instructions for the machine or lubricate all available rubbing metal parts and assemblies.
It is very convenient to use a medical disposable syringe for lubrication, just choose the size so that it fits in the neck of the oil container. The needle must be removed when filling with oil.
Repair of the sewing machine Seagull
The main malfunction of machines of the "Seagull" type, performing a zigzag stitch and several types of finishing stitches based on it, are skips, looping of the lower and upper threads, as well as thread breakage from above and below. It is these faults and how to fix them that we will consider in this article.
Thread breakage most often occurs with Chaika-type sewing machines. The first reason leading to thread breakage is the bent point of a blunt needle, which breaks the thread during its movement. With the help of a magnifying glass, the state of the needle point is very clearly visible.
Use serviceable needles and designed for Chaika sewing machines, in accordance with the instructions.
A broken thread can be the result of many malfunctions, for example, if the needle touches it when entering the needle hole, then the thread will break periodically. When performing a straight stitch, the needle should be located in the center of the hole in the needle plate, evenly removed from its sides, and when performing a zigzag operation, the needle position L should be the same with R.
Longitudinal installation of the needle in the center of the needle gap is carried out by shifting the needle bar frame, fixed with two screws on the rocker arm, in the upper part of the machine (turn the flywheel on the zigzag line and you will see this mount).
Loosen these screws and set (on a straight stitch) the needle exactly in the center (offsetting the needle bar frame). After that, check the position of the needle with its left and right injection. I hope that the entry of the needle (at the maximum width of the zigzag), on the right and on the left, will be evenly removed from the center. If it touches the edge of the hole at the maximum width of the zigzag, contact the master, this case is already for him.
Adjusting the vertical position of the needle
The transverse position of the needle is regulated by a rod mounted on a plate with two screws and a plate pressing the needle bar frame to the bracket rod. Adjusting this assembly is quite complicated and requires experience, but, unfortunately, it is this mechanism that can spontaneously go astray during operation, especially the Chaika electric sewing machine. Therefore, if you decide to repair your sewing machine yourself, you should learn how to adjust the position of the needle, since moving the needle forward is the cause of its breakdown, and moving away from the seamstress is the cause of skips.
Adjusting the needle position requires professional knowledge and experience. If you are not sure that you can do it yourself, contact the wizard, as it can cause other components to fail, the repair of which cannot be learned from a boring book stuffed with technical terms and diagrams.
It can be added that when using a curved needle, notches may form on the nose of the shuttle, which “unwind” the thread and break. The nose of the shuttle should be perfectly smooth and sharp, without roughness. Its condition can be determined by running a fingernail along the edge of the spout or using a magnifying glass. The pressure plate tightening screw must not be serrated, the latch handle must be clearly fixed and its surface must be clean and smooth. The shuttle itself must also be perfectly clean, without nicks and rust spots.
Adjusting the needle bar and attaching the tensioner
When sewing rough fabrics, sometimes the needle moves up along with the needle bar. There are gaps in the stitch. In this photo, the arrows indicate where the needle bar fastening screw and the upper thread tensioner fastening screw are located.
The incorrect position of the hook of the Seagull sewing machines leads to thread breakage and the appearance of other stitching defects, including gaps. Passes usually appear due to the wrong position of the shuttle at the moment of meeting with the needle - the nose of the shuttle does not capture the loop formed, passes by and a gap is formed. Many other factors can be the reason.
In order to correctly set the position of the meeting of the nose of the shuttle and the needle, it is necessary to adjust the position of the shuttle. You can loosen the two bolts that secure it and gently, using a powerful screwdriver, move or move away the move along with the shuttle in relation to the needle. The shuttle travel rotates on an axle rather than moving back and forth. This is a very important point. No need to pull it out with a nail puller or hammer it in with a hammer, it easily turns on its axis. It is difficult for an inexperienced person to immediately understand what is at stake, but it is also very difficult to explain in more detail. Everything that can be added, carefully understand before you twist something, and even more so unscrew it. There should be no remaining parts after repair.
Shuttle and needle adjustment parameters (Seagull)
At the time of the meeting of the nose of the shuttle and the blade of the needle, the following parameters must be observed: the gap between the nose and the blade is approximately 0.15 mm; when the needle leaves the lower position to a height of 1.8 - 2.0 mm, the nose should approach it above the eye of the needle by 1 mm, at least, but not more than 3 mm.
By the way, a very important point is the lifting of the needle from the lower position (1.8 - 2.0 mm). This parameter affects the formation of the needle loop and should be given special attention. In order for the nose to grab the thread from the needle, it is necessary that a loop is formed, where it passes, hooking it. That is why the needle must first go down and then, having risen a little, already meet the looper nose.
The position of the needle is also regulated by the needle bar, for this there is a screw for attaching it to the sleeve under the front cover (see above).
If you set such parameters for adjusting the shuttle, then sewing machine "Seagull" will work relatively well. But, unfortunately, this repair is not over. There are still many other shuttle settings that are quite complex and necessary for the Chaika sewing machine. It is there that the reasons for the looping of the thread and such a rare phenomenon for sewing machines are hidden - the breakage of the lower thread. The complexity of the presentation of this material is that for almost any model of the Chaika sewing machine, engineers have provided their own settings for this unit and, moreover, requiring great experience from the performer. For which they are thanked, at least from sewing machine repairmen. They will not be left without work as long as there are "Chaika" sewing machines.
Flywheel Friction Washer
Sometimes you have to remove the flywheel from the machine. There are only three parts in this knot, but many people cannot assemble it correctly. This is due to the fact that it would be more logical to insert the petals of the friction washer inside the slot of the shaft, which is why they do so. As a result, the machine starts to spin idle.
The petals should not be turned towards the body of the machine (shaft), but towards you. Not only that, they can be supplied in "two versions", choose one in which the limit screw will not interfere with tightening the flywheel mount.
