Maintaining and servicing your Juki industrial sewing machine is of utmost importance to ensure it performs in top condition and continues to provide quality production. Oil is the lifeblood of your machine and plays a critical role in keeping it well lubricated, preventing corrosion and increasing efficiency. Oiling your sewing machine regularly is a great way to extend the life of its components and keep it in the best working condition. Here is an easy guide on how to oil your Juki industrial sewing machine.
Before you begin, make sure to unplug your machine, and spread newspapers or a drop cloth underneath it. This will help to keep any oil from seeping onto your floor or counter.
Take off the metal hood that covers the electrical components and motor to expose the base of the machine. Open the thread take-up arm where the tub and belt of the machine are located. You will see a large black ball, an axel, and related components that need to be lubricated. The black ball and axel will lubricate ball bearings when oil is applied. To prevent any oil getting onto these surfaces, wrap masking tape around these bearings.
Oil Container/Dropper
You’ll need to select the right type of oil and the method of applying it. The ideal oil to use for a Juki industrial sewing machine is a heavy-duty sewing machine oil or 3-in-1 oil designed for sewing machines. Never use WD-40, as this contains detergent that will crystallize over time and cause gumming.
The best way to apply the oil is with a plastic oil container or dropper bottle. This allows you to drip oil directly onto the parts that needs oiling and will prevent any spillage.
If you don’t have a small oiling container, you should use a clean piece of cotton or a lint-free rag. This should never be applied directly onto the bearings, but rather gently dabbed onto the edges of the bearings.
Oiling Areas
Once you are ready to begin oiling, use the dropper to selectively put a few drops of oil in a line and spread it evenly around each bearing, the axel, and the black ball. To ensure that the oil reaches all parts of the components, gently turn these parts and repeat the process.
Apply a few drops of oil along the path of the top shuttle. This will help to keep the shuttle in top condition and prevent it from gumming up. Wipe off any oil residue and excess with a soft cloth.
Finally, turn the hand wheel of the machine gradually in a clockwise direction. The oil will spread evenly throughout the parts and will help to reduce friction between them. Once you have completed the process, you should be able to feel smoothness when you turn the wheel.
Maintenance Tips
To increase the life of your machine, it is important to oil it regularly. As each Juki industrial sewing machine is different, check your instruction manual for instructions on how often it needs to be lubricated. If you are unsure, it’s best to oil your machine at least once per month.
To ensure optimal performance, be sure to use only the highest quality oil and make sure to use the correct type for your machine. Make sure to store the oil in a cool place away from direct sunlight.
Also, be sure to clean your machine regularly. Dust and debris from fabrics can accumulate in the area around the shuttle, causing it to miss stitches or run slower. You should also check that all parts are functioning correctly and clear away any thread or fabric scraps when you change the needle or different materials.
Replacement Parts
In addition to oiling your machine regularly, you should also check for any worn or damaged parts. If any are present, make sure to replace them as soon as possible. Parts for industrial sewing machines like Juki can be expensive, however it is far more cost-effective than having to repair the machine due to wear and tear. OEM parts are a great option as they are made specifically for your machine.
If you notice that your machine is making an abnormal noise or is running slowly or inconsistently, do not try to repair it yourself. It is always best to contact a professional to assess the issue so that the repair is done correctly.

Q:What is the best way to oil my machine?
A:The best way to oil your machine is to use a plastic oil dropper for precision and to prevent spills. Make sure to apply oil evenly in a line and turn the components gently to let it spread.
Q:How often should I oil my machine?
A:It really depends on your machine and the amount of use it gets, however in general it’s best to oil your machine at least once per month. Be sure to refer to the instruction manual for specific instructions on how often your machine needs to be oiled.
Additional Care and Maintenance
With proper care and maintenance, you can keep your Juki industrial sewing machine running in top condition for years to come. Be sure to inspect the machine regularly to see if any parts need to be replaced. Also, be sure to dust the shuttle periodically to keep it free of fabric and thread scraps.
If you are using a Juki that has been sitting in storage for a long time, be sure to inspect it for rust and inflammation. If any is present, lubricate it with a light oil before use. Also, clean and oil all moving parts and inspect the electric components for fraying or exposed wires.
Finally, make sure to adjust the tension settings and check the stitch quality regularly. Taking the time to do these steps will ensure that your machine will work efficiently and continue to provide quality production.
