Sewing machines do not lose their popularity even in the twenty-first century. Those who were born in the Soviet era remember that girls were taught from childhood to sewing various things, from gloves to jackets and coats.
During the Soviet era, most people did their own sewing machine repairs. Even today, those who attend sewing and sewing courses understand that it is better to repair a sewing machine on their own than to take it to a service center:
- First, companies that repair sewing machines demand quite a lot of money from their customers for the services they provide.
- Secondly, the device of even modern machines can be figured out in a matter of hours, you should only carefully approach this issue, and in the future this will allow repairing sewing machines without involving third parties.

Basic rules for operating a sewing machine
Let's take a look at the basic rules for operating sewing machines:
- Sewing equipment should not be placed near batteries or heaters. But at the same time, it should be in a dry room, in which there are no signs of dampness;
- Before starting work, it is necessary to select the necessary materials and tools, needles and threads that will be needed in the process;
- Before you start sewing, you need to make sure that the needle and thread guide are in the up position;
- Remember that the sewing machine needs to be helped at the time of sewing by pulling the fabric towards you;
- After the sewing work is finished, raise the presser foot and pull out the fabric. Next, cut the thread, finding in advance its free end, the length of which will be equal to a maximum of seven, but at least five centimeters.
Problems with the sewing machine
There are rules and they must be followed. The use of quality materials and additional tools minimizes the occurrence of problems and malfunctions when working with sewing machines. Therefore, the following reasons that led to malfunctions in operation are the most common:
- Broken thread. Breakage can occur both with the upper and lower threads. In the first case, the problem is associated with the selection of low-quality threads or the size of the needle is not correctly selected. In the second case, the problem of a malfunctioning sewing machine may be associated with irregularities, the presence of burrs in the bobbins, and improper winding of the thread.
- Problems with advancing fabric. If such a problem arises, you need to carefully look at what position the teeth are in. If they are lifted up or lowered to the bottom, then it is required to bring them to a normal state;
- Cutting through the fabric. If such a problem arises, in order to fix the machine, we need to reduce the pressure of the presser foot, and check the condition of the needle, it may be too dull.
Advice:
Serious problem - knocking of the sewing machine
The above problems are not serious and are eliminated in a matter of minutes. But there are some types of problems that occur infrequently. Therefore, repairing sewing machines with your own hands, if they arise, will take a lot of time.
The most difficult, most serious breakdown should be considered the appearance of a knock when the sewing machine is running. To solve this problem, it is necessary to pull the flywheel several times, and do this in accordance with the axial direction of the machine.
In order to repair the sewing machine, it must be disassembled. We disassemble the sewing machine in the following sequence:
- Remove RP (manual drive). It is necessary to remember its location, this will allow you to subsequently assemble a sewing machine in a short period of time;
- Unscrew the stopper from the nut, which is a classic screw. It is under a manual drive, at the time of assembly it must be screwed back to its original location;
- Remove the flywheel. This must be done carefully, avoiding damage to it, in case of a malfunction of the flywheel after assembling the machine, you need to see if everything is in order with it;
- Remove the bobbin that looks like a cone. It is located below, after the flywheel. Finding it will not be difficult;
- Remove the bushing from the shaft base;
- Slide a tin washer onto the shaft. It is very simple to make such a washer, just cut out the bottom of the can.
A washer in 40% of cases is a guarantee of high-quality performance of work using a sewing machine. Sometimes adding it to the machine is enough to solve the problem, but this does not always happen. When adjusting the operation of sewing machines, in 60-70% of cases, it is necessary to turn the rail 180 degrees.

The needle is the key part of the sewing machine
The needles are the basic elements that make the sewing machine work. Its further work depends on which needle is chosen. If a defective needle is picked up, then the occurrence of the above problems is not a rare case, because the needle is the basis, and without it it is impossible to sew a single thing.
Therefore, when choosing a needle, you must carefully consider its size and thickness. You also need to check the numbering of the needle if you are doing any complicated sewing work, otherwise it may happen that the thing will turn out not the way you imagined it earlier.
There is another problem in which the wrong needle selection can lead to stretching and tissue damage. If the needle is too thick and the fabric is thin, then you cannot use the needle with such fabric, otherwise it will break.

Using too thick fabric with a small needle may break the needle. In order to sew something from a compacted fabric, you need to choose a thicker needle, if it is not available at home, then go to the store and purchase it. Before doing this, measure the thickness of the fabric in advance - this will allow you to pick up the needle in the store in a shorter time, you will need to tell the seller the thickness of the fabric, and he will independently select the needle of the size you need.
