There is no denying the difficulty of most sewing machine repairs. Even seasoned seamstresses must often call a repairman to evaluate and repair a malfunctioning machine – but what if you’d like to undertake the challenge yourself? With the right knowledge, this task should not be daunting. Here we’ll discuss some of the basics of sewing machine repair and maintenance.
Begin by completely unplugging your machine from any power source. Safety first! Then, remove the stitch plate and inspect the bobbin area for any jamming or excessive accumulation of lint. Any case of jammed yarn can be taken care of by removing the bobbin case and cleaning the hook race and feed dogs. You can also inspect the hook assembly as well as the bobbin tension.
You should then reinstall the hook assembly, ensuring the hook race is aligned with the hook assembly lock, followed by the installation of the bobbin case. After this, check the hook area again to verify that it is freely rotating and the hook timing is set correctly. Lastly, adjust the bobbin tension to ensure uniform stitch quality.
Now that you’ve taken care of the hook issues, it’s time to perform a machine service. This process should begin with a cleaning of the interior. For most machines, it’s worth using a soft brush to remove oil residue, lint and dirt. If the machine has been sitting idle for more than a year, then a complete oiling of the hook, feed dogs and other metal parts is recommended, to restore proper lubrication.
This machine servicing should then extend to a complete inspection of the machine for any loose, worn or missing parts. Make sure to use genuine manufacturer’s parts for any replacements to guarantee peak performance and longevity. If possible, ensure all the screws are tightened and the machine is at the manufacturers OSHA specifications. This is key to minimizing any downtime due to breakdowns during use.
Rebuild Feed Dog And Bobbin
One of the things to be aware of while carrying out repairs is the need to rebuild feed dog and bobbin. The feed dog works like a small, moving belt; it moves fabric along under the needle, helping maintain an even stitch pattern. The bobbin is a spool of thread found beneath the needle plate.
The process of rebuilding these two parts is relatively straightforward. First, make sure to remove the feed dogs, taking extra caution when unpinning any unthreaded loops. Then, discard the worn or threadbare feed dogs, and replace them with new parts. Once you place them back onto the arm of the machine, re-pin the threads.
The process for replacing the bobbin is also fairly simple. First, check to make sure the bobbin is inserted into the bobbin case correctly and is aligned with the hook assembly. Then, pull the thread and make sure the bobbin thread is visible and has no knots. After this, you can start winding the thread on the bobbin, and in no time your repair is complete!
Safety Checklist
Performing regular safety checks can help you stay up-to-date with the condition of your sewing machine, as well as prevent any major malfunctions. Here is a list of things to look for during a safety check:
- Check the power cord for any wear or tear, and make sure it’s properly grounded.
- Inspect the spool and bobbin to ensure nothing is visibly damaged.
- Inspect the needle for any burrs or damage. If you find any, replace the needle cannula.
- Make sure the tension is properly adjusted and the pressure foot is correctly adjusted and level.
- Check the needle bar height to ensure it’s height isn’t too high.
- Check the stitch quality and make sure it’s even. If it’s off, then adjust the tension.
Regularly checking these parts is paramount to keeping your sewing machine in good condition. Proper maintenance of your machine will ensure it is running smoothly and is always ready when you need it.
Troubleshooting
If your machine experiences any difficulties during use, there are some standard troubleshooting steps you can follow, such as checking the power supply, the needle and the bobbin. If the issue persists, you can investigate further. You can refer to user manuals for more information or take the machine in for the professional service.
In some cases, you may find that the machine at hand is an older model and parts may not be easily available. In such cases, you can consult with professional technicians or manufacturers to source parts. It may be possible to find hard-to-find parts on eBay or other online marketplaces.
In more serious cases, like motor failing or electronic control systems malfunctioning, you’ll want to take the machine in for professional repair. Here the technicians can provide in-depth analysis, offering necessary parts and service to get your machine in peak working condition.
DIY Repairs
At times, basic repairs can be performed with little to no technical know-how. This often involves inspecting the drive belt, lint buildup and checking the timing of the feed dog versus the needle plate. More frequently, a quick patch or functional sew job can be completed with the tools and materials at hand.
For a more comprehensive repair, you may want to consider a DIY guide. DIY instructions are a great way to better understand the repairs and maintenance required for your particular machine. You can find a variety of helpful resources; such as instructional videos or written guides, online from various sources including sewing machine repair specialists.
In conclusion, with the knowledge of what needs to be inspected, serviced or replaced and the right tools, you can tackle the repair of most sewing machine issues yourself. For minor repairs, you may need just a few tools and a guide, however for major repairs it is best to consult with a professional technician.
Additional Maintenance Steps
Having a well-maintained and serviced sewing machine is essential for continuous use. To maintain its health, it’s best to clean the machine after each use, ensuring that all dust is properly removed from its exterior as well as its mechanical parts. You can do this by wiping the machine with a damp cloth, or by using a micro canister vacuum to remove lint.
It’s also important to oil the machine on a regular basis. This helps to ensure that all parts are properly lubricated and that they move freely when stitching. To do this, you can use a light machine oil, adding small amounts with a dropper or brush. However, be sure to check the user manual first as some sewing machines don’t require oiling.
Furthermore, using a cover when the machine is not in use can help to keep dust and dirt away. Many furniture stores offer covers that are made specifically for sewing machines. You can also use a plastic covering or a cotton sheet if your machine isn’t too large.
Understand When To Call For Professional Help
It’s important to recognize when a machine issue is beyond typical maintenance and repair. If you have inspected the hook and bobbin and done a full machine service as detailed in this article and the issue still persists, then it’s advisable to call a professional. A technician has the knowledge and experience to accurately inspect, diagnose and repair the machine.
Nor should you be hesitant to call a repairman. Doing so may save you time and money. Despite your enthusiasm, repairing a machine can often be harder then anticipated, and can even turn into a more complex problem that requires professional help.
Useful Tools To Have On Hand
Having the right tools in order to repair and service your sewing machine is also critical. This could include small screwdrivers, a lubricant, standardized parts, needle threaders and thread cutters. It may also be worth carrying out some research to learn about special tools that might be useful for a particular model of machine. There are also some common tools, such as screwdrivers and pliers, that can come in handy for a variety of different issues.
You can purchases tools such as these from any local hardware store, or online from sewing machine shops. With the right tools, you can feel more confident when attempting a repair.
Taking Apart A Sewing Machine
In some cases, it may be necessary to disassemble the whole machine. This is likely needed to access the interior parts in order to carry out a full machine service. Doing this requires additional steps, such as the removal of additional guards, screws and other parts that may be in the way.
Before tackling this task, ensure you have access to the necessary tools, and that you’re familiar with the machine as well as the user manual. Additionally, remember to take any necessary safety precautions and make all the necessary adjustments when reinstalling any parts.
