Essential Tools for Sewing Machine Repair
If you plan to start tinkering with your sewing machine, you will need some basic tools and supplies. You have to ensure that whatever you have in your workbench can serve the purpose of a sewing machine repair. Some of the essential supplies that you need include: small screwdrivers, multipurpose tweezers, adjustable wrench, and a feeler gauge. In addition to these, you may need cleaning supplies, wax paper, emery cloth, and some light machine oil. You will also need extra needles and a collection of small sewing machine parts.
Diagnose the Problem
The first step in a sewing machine repair is to try and diagnose the problem. At this stage, it may be necessary to read the manufacturer’s manual and thoroughly inspect the sewing machine. Be sure to look for bent or damaged parts and examine them with the assistance of a magnifying glass. On a mechanical sewing machine, make sure that the timing is correct or if there are any interference issues.
If you are dealing with an electronic sewing machine, you will have to look for any shorts in the wiring, or if the main circuit board is functioning properly. Do some research about the individual components of the electronics and try to identify which of them is causing the issue. Be sure to check for any loose connections and test the various parts.
Replacing Parts
If your machine has faulty parts, then you will have to replace them. For this, you will need to shop for genuine parts specified by the manufacturer. If you cannot find the exact part, then you may have to buy a compatible one that fits the machine. When it comes to buying a new part, make sure to buy one that is compatible with your sewing machine.
Adjusting the Tension
If your machine is stitching properly but it is not producing even stitches, then the tension needs to be adjusted. It is important to understand that too tight or too loose tension can cause the stitching to be uneven. Adjust the tension according to the manufacturer’s guidelines. Usually, it is written in the manual that comes with the machine. If you are unable to find specific details about adjusting the tension, use the trial and error method to find out the best tension setting for your machine.
Align the Feed Dog
If your machine is not feeding the fabric properly, it is possible that the feed dog is not aligned properly. To straighten out the feed dog, you can use a feed dog screw. Make sure to properly clean and lubricate the feed dog screw before fitting it back in. It is also important to keep the area around the feed dog clean, as any lint or dirt will affect the stitch quality.
Oiling the Machine
Machines, regardless of how old they are, need to be lubricated. This helps to prevent rust, corrosion and wear and tear of the machine. It is important to use a recommended machine oil, as some oils may not be suitable for the machine and can cause it to damage the machine. Make sure to properly oil all the components, as this will ensure that the machine runs smoothly for a long time.
Check the Belt
If the machine is not running smoothly, then it might be due to a broken or loose belt. These belts can become loose or worn over time. A broken belt can cause the machine to run more slowly or stop completely. If the belt is damaged, you will have to replace it. If the belt is loose, then you can tighten it by adjusting the tension.
Replace Motor Brushes
If the sewing machine is running but the stitch quality is poor, then it could be due to worn out motor brushes. These brushes help to supply electricity to the machine motor, and over time they may become worn out and cause the motor to run erratically. In this case, you will have to replace the motor brushes.
Check the Wiring
If your machine is not running or the motor is making strange noises, then the wiring may be damaged. Faulty wiring can be a major cause of problems in a sewing machine, as it can disrupt the flow of electricity to the other components. Always check the wiring and replace any damaged wires as soon as possible.
Clean the Machine
Finally, it is important to clean the machine regularly. Make sure to dust off the interior parts and the exterior of the machine. You should also clean the lint and dust that accumulates around the needle plate and feed dog. Cleaning the machine will ensure that it runs properly and can help to prevent any potential mechanical issues.
