Common sewing machine problems

Stuck needle. The first thing you can try to do is slowly rotate the flywheel, trying to free the needle. If the actions did not lead to any result, then you should seek the help of engineers. Possible causes of the malfunction: improper lubrication (unqualified application of lubricants can even lead to complete jamming of the internal mechanisms of the device; choose oil in strict accordance with the technical instructions and operating rules), tangling the threads when forming a stitch (especially common when making a Zigzag seam "on the domestic "Seagulls"). Incorrect unraveling leads to a break in the tip of the needle; to fix the problem, the master completely disassembles the shuttle mechanism. Also, the needle jams due to jamming of the needle bar - it is not possible to eliminate the defect without completely disassembling the device.
Winding. The hook is not high enough in relation to the needle. Complete (or, depending on the degree of damage, complete) disassembly is required. Also, the use of a bobbin case from other models often leads to the fact that the mechanism winds, to avoid this, repair it only at the masters. Repair of sewing machines in Moscow is one of the most demanded services in the Remontano company.
Skips stitches. Possible causes that lead to a malfunction: needle damage (wear during operation, deviation, loss of sharpness of the tip, improper installation of the part), incorrectly selected thread (before using the device, carefully read the instruction manual!), high angle deviations of the loop-lap, the formation of a loop-lap on the opposite side of the needle (the problem is typical when a polished thread is used), one of the possible solutions is to increase the stroke of the shuttle. Also, skipped stitches are common when sewing with nylon fabric. A wide hole in the needle plate, the loss of its original characteristics (due to inaccurate handling) does not allow you to create a loop-overlap sufficient to capture. The worn part is replaced with a new one. Please note that it takes a long time to search for it even in a specialized store. If the position of the working material is incorrect, it twists, and the loop goes to the side, one of the possible solutions to the problem is to replace the thread with a denser one.
Vomit. When the device breaks the upper thread, it is worth looking for the source of the breakdown in the following factors - the use of poor quality materials, violation of installation rules, failure of the tension regulator. The tension force is adjusted using a special control nut; when replacing a low-quality thread, you can also achieve a positive result. Be sure to use working tools with the correct eye diameter, sharpening the cutting edges if performed by a professional corrects some of the defects. It is worth noting other factors that increase the likelihood of a breakdown: excessive pressure on the lower foot, non-compliance with the recommendations when refueling the hook, notches formed on the surface (polishing required), lubricant that is not suitable for the type of equipment, poor quality oil.
Noisy. Most often, the problem occurs due to the lack of qualified maintenance for a long time. Internal mechanisms become dirty and can not cope well with the tasks. Knocking during sewing indicates that the needle is hitting a hole in the needle plate. Other reasons: hit of the working material in the shuttle mechanism, clogging of the conveyor rail with tows, failure of the crankshaft cam.

DIY repair

We do not recommend you to repair complex equipment with your own hands. This comes with many risks. First of all - the lack of special tools and skills to use them for diagnostic and restorative procedures. Instructions from the Internet and videos from "home masters" are of little help in such work. It is also difficult to find the necessary spare parts and components - they are not always available even in specialized stores, and searching for them on the Internet carries additional risks. There is no guarantee of a quality result, and the cost of subsequent repairs can increase significantly. The only solution in this situation is to turn to professionals for help, since prices are now available to almost everyone.

Advantages of contacting the masters of the Remontano service center

In the event of a serious breakdown of the sewing machine, only a competent specialist can help it. Although, in most cases, as practice shows, complex repairs are not required for a home-operated machine, but in order to be able to use it, it is only necessary to configure and adjust it. And it is quite possible to do it on your own, the main thing is to learn and understand how to properly set up the sewing machine before work and which parts should be adjusted in it.

How to set up and adjust the sewing machine

The main malfunctions requiring tuning and adjustment

The main malfunctions that require timely adjustment and adjustment can be called:

stitch instability, which consists in the formation of gaps in the line, different lengths of threads, a break in one of them or both at once;
the manifestation of violations in the line, namely the contraction of the fabric in the form of an accordion, excessive pulling or loosening of the loop, as well as beveling the line;
change in stroke, accompanied by noise, the appearance of "heaviness" or jamming.

Stitch instability

The occurrence of all these malfunctions suggests that you need to take a closer look at the operation of the sewing machine, determine the cause of their occurrence and try to eliminate it. If you do this at the very initial stage, then it will not require much effort. Continued operation of the sewing machine in the wrong mode may require expensive repairs that only a professional can carry out.

Basic rules for self-configuring sewing

Setting up a sewing machine with your own hands is quite simple. To do this, it is necessary to adhere to a certain sequence of actions, the main stages of which are:

Among other things, before starting work, it is necessary to set the stitch length. Usually their exact value for different types of fabric and a particular line is indicated in the instruction manual for the device. In this case, the average value of this value is from 1 to 2 mm when using thin fabric and not less than 3 mm - thick matter. It is also worth checking the sharpness and compliance of the sewing needle. If the needle is blunt or too fine for a particular type of fabric and thread, skipped stitches will occur.

You can learn about it from our article.

Choosing a sewing machine needle

No matter how strange it may seem, but the needle is one of the most important elements of the sewing machine, so before you wonder how to properly set up the sewing machine, you need to check this element. In the process of sewing, the needle makes several hundred punctures in the fabric, some of which are not thin and light. Over time, this leads to its blunting, and subsequently to the fact that it bends. And in the event that, in the course of its movement, the needle hits the metal of the device case at least once, then the tip will certainly doubt. At the same time, inexperienced craftsmen may not pay attention to such an incident and during a visual inspection they will not notice the defect that has arisen. But in fact, it will exist, and when the tissue is punctured, it will form relatively large tears on the latter. The thread, which at the same time passes through the eye of the needle, will cling to the deformed point, while slowing down with the appearance of an excess of it in the stitch. Loops will begin to form in the line. In addition, a bent, blunt needle can cause permanent thread breakage, especially if you are sewing a complex section of the product when the upper thread is pulled to the maximum.

In such situations, manual and electric sewing machine adjustments and adjustments are not required as such. And to perform the work in normal mode, you just need to replace the needle yourself. This element in the machine must be changed as often as possible. This will not complicate the work in any way, but on the contrary, it will make sewing really high-quality and neat.

When replacing the sewing needle, it is necessary to choose this element strictly corresponding to the type of machine. In no case should a needle intended for an industrial sewing machine be installed in a household appliance. It is extremely difficult to confuse them, since needles for industrial devices do not have a cut on the flask. Using such a needle in a household sewing machine, the gap between the needle blade and the nose of the hook is broken, which at best leads to skipped stitches. And at worst - to damage the hook of the sewing machine. Also very important is the correct location of the element in the needle holder, which consists in finding the blade from the side of the shuttle nose.

Choosing and installing a needle

Before inserting even a new needle corresponding to the type of sewing machine into the needle holder, you need to make sure that there is no curvature of it, which at first glance may not be noticed. In order to make sure that the needle is absolutely straight, you can put it on a glass or mirror. The gap will be visible immediately. In addition, you need to choose a needle in accordance with the fabric used. So for sewing "difficult" fabrics, such as stretch, jeans or artificial leather, there are special needles that have a special shape that contributes to a better passage of the needle through the fabric, thereby eliminating skipped stitches and uneven loops created by the upper thread.

The needle must be selected according to the number of thread used. At the same time, it is worth considering the feature of new sewing machines, which consists in the presence of a guide limiter under the surface of the table, which prevents the needle point from leaving the side. At the same time, the distance from it increases with increasing tissue thickness.

Choosing a needle according to the type of fabric

Setting the interaction between the needle and the hook of the sewing machine

The joint work of the shuttle and the needle

The quality of the result obtained during the sewing process depends on the setting of the shuttle assembly and the needle of the sewing machine, or rather on the correspondence of the gaps between them to the correct values, in the absence of which gaps, loops and breaks in the lower and upper threads can also occur in the lines. In order to make this adjustment, it is necessary to understand how the machine works when forming a buttonhole.

So when the needle is raised by 1.5-2 mm from its initial position, a loop is formed from the upper thread, located slightly above the eye. In this case, the nose of the shuttle should pass almost close to the hollow of the needle. This distance should not exceed 0.15 mm. The value from the nose of the shuttle to the eye of the needle in this case should be 0.5 mm. These values are approximate and correspond to work with fabrics of medium thickness. Depending on the type of material used, they may vary somewhat. Understanding their numerical value can only be done experimentally in the process of doing work, and such skills in most cases come with experience.

It is also worth noting the importance of the correct installation of the vertical position of the gear rack. She is responsible for the movement of the fabric relative to the needle and the body of the sewing machine during operation. At the moment when the needle pierces the fabric, the upper edges of the teeth of the rail should be at the level of the desktop of the sewing machine.

Proper care of your sewing machine

In order to ensure that each time before using the sewing machine it is not required to adjust it, it is enough to follow certain preventive measures, the main of which include:

lubrication of all main parts must be carried out with special oil at least once every six months;
after each use of the sewing machine, it is imperative to remove from its surface, as well as the covers of the hook and the needle plate, all dust and dirt formed during operation;
before hiding the machine in a cover, it is necessary to make sure that there are no torn threads and fabric in its structural elements, as well as placing thick paper or cardboard under the foot, lower it all the way;
storage of the sewing machine must be carried out in a case;
Pedal and drive cords should be coiled as neatly as possible to avoid kinks or breaks.

Proper storage of the sewing machine

Adjusting the sewing machine after a long break in work

If the sewing machine has not been used for a long period of time, it must be checked and adjusted before use. This is necessary in order to make sure that during the long “standing” all the main elements and mechanisms have not rusted due to improper storage. To do this, you need to lubricate all the metal parts of the device with the oil that comes with the sewing machine. If it is not there or it is over, then you can use ordinary engine oil. Further, without lowering the foot, it is necessary to drive it away at low speed in vain, so that all the elements that did not get oil are also processed by it.

After all these steps, you need to replace the sewing needle, and only after that proceed with threading and using the device. The first line is best done on a piece of unnecessary fabric in order to avoid getting machine oil on the material of the product that will be made using a sewing machine. In this case, it will become clear whether the line is correct. After that, you can safely start working with full confidence that this device is working properly and will not spoil the main fabric.

Thus, it is quite possible to set up a sewing machine on your own. The main thing is to understand what kind of problem arises in the process of doing the work. All basic operations are standard and apply to both manual and electric sewing machines. If every time before starting to use, check all the main parts and components of the device, as well as take preventive measures in a timely manner and use it correctly in accordance with all points of the instruction manual, then the question of how to set up and adjust the sewing machine will not arise.

Benefits of professional sewing machine repair at Vostok-Pole

Vostok-Polyus managed to accumulate great experience in the field of repairing sewing machines in Moscow. This is what allows the company to provide its customers with exceptional quality services, but at the same time for optimal cost. Our repairmen in their work always use specialized equipment that does not cause the slightest harm to the elements of the sewing machine. Parts of the unit that have worn out over time, we only replace original spare parts that have been tested for strength and quality.

These machines are 40-50 years old, and they are still sewing, which cannot be said about modern imported consumer goods. I bought it and threw it away, but my grandmother's rarity is carefully kept in many families, as a memory and as a masterpiece of Soviet industry.

Podolsky Order of the Red Banner of Labor Mechanical Plant named after M.I. Kalinina produced such class 2-M sewing machines.

Unpretentious, reliable, easy to operate, always helped out in difficult times, and allowed many to earn a living. It is a pity to see how young people are now getting rid of old things that can serve their owners for a long time. Most of these cars now rest in a landfill. And before the sewing machine was affectionately called the nurse, she fed and sheathed the family.

It's time to get down to business.
First of all, we cut off the fabric that women love to sew on the "waist" of the machine. Believe me, there is no benefit from it, they stick used needles into it, bent, blunt, and then they try to reuse the same needles. And they cannot understand why this machine does not sew. In addition, after such sticking, the coating deteriorates and such scars remain. Used needles should be thrown into the trash can, where they belong.

We disassemble the machine, remove all covers, the needle plate, disassemble the shuttle, as shown in the photo.

It can be seen that pile from fabric and threads has accumulated on the body of the shuttle, there are even pieces of thread and all this is mixed with thickened oil.

And here, too, dust and thickened oil.

And this is the place where not a single seamstress, for the entire time of operation of the machine, never looks. Here pile and dust and sand accumulate, in general, everything that gets into the holes of the needle plate.

We remove all this byaka with a needle and tweezers.

In her how much is here.

The gear rack also needs to be cleaned, it is best to do this with a large needle.

And of course we clean the shuttle device, it is good to use kerosene for these purposes, if it is not there, then you can remove the thickened oil with a knife or a screwdriver.

All the dirt and old oil was removed, now we proceed to lubricate the machine.
For these purposes, it is best to use a regular disposable syringe, with the thickest possible needle. I don’t advise you to lubricate with an oiler, it pours oil, and you will get the machine dirty, and you will get dirty yourself. Oil can be purchased at any hardware store. Lubricating Oil Household will do.

Here, the arrows indicate the technological holes for lubrication, we instill 3-4 drops into each hole, no more is needed.

And here it is imperative to drip into both holes, one hole of the needle bar and the second presser foot.

In these places, the needle bar is rarely lubricated at all, the friction here is frantic and the metal is produced, a backlash is formed, as a result of which the needle hits the needle plate or the shuttle.

And accordingly, the foot should also move freely up and down. Without braking, otherwise the fabric will be pressed unevenly, it will simply walk under the foot and the stitches will be of different lengths.

And one more place that must be lubricated.

Winding the bobbin, drip three drops of oil.

And now we put the machine on its side. The arrows indicate all the places that need to be lubricated.

After complete lubrication, we turn the handle for a couple of minutes so that the oil flows into all the joints and slots of the machine mechanism. Feel the difference, it began to work in a completely different way, softly and quietly.

Pay special attention to the installation of the friction device.
Here you can see how not to do it, usually amateur masters install the friction washer this way, as a result, they do not turn on the working stroke. After that, they begin to turn on their imagination, cut out pucks from cardboard, wind the wire, in general, whoever is what.
