Service Class 7 Troubleshooting Series: Cleaning a Class 7 Style Sewing Machine

Your Class 7 Style sewing machine is an asset to your operations; one that needs careful maintenance to keep it in proper working order.

In our latest video tutorial in our troubleshooting series, Service Thread Sewing Sales and Tech Support Manager Dane Hatcher reviews the necessary steps to keep your sewing machine cleared of debris. This prevents damage to the machine, issues with your thread, and many other sewing difficulties.


Cleaning your sewing machine requires attention each day, as well as weekly routine maintenance.

The best tool to keep Class 7 sewing machines clean of lint, oil, and other debris is compressed air, which should be used to remove all excess fibers from any surface of the machine where thread regularly runs. You may use either an air compressor or a can of compressed air to accomplish this. You will want to have a clean cloth on hand for cleaning as well. 

Daily Cleaning of Your Machine

Each day, your Class 7 sewing machine should be cleaned so it is ready for the next day’s use. First, clean the entire front section of the machine with compressed air to remove any excess fiber particles and oil. 

Next, remove the throat plate and using compressed air, blow all lint out of the interior of the machine. To remove any additional lint buildup and excess oil within the mechanism, wipe everything down with a clean, lint-free cloth. 

Finally, the machine should be oiled again so that it is ready for the next day’s use. You can learn more about the proper way to oil a Class 7 sewing machine, ensuring you address each of the 38 touchpoints, in our tutorial here

Regular, Weekly Maintenance

With daily attention, there’s not a lot of additional cleaning maintenance that a Class 7 sewing machine requires. Approximately once a week, you should remove the race, take apart the plates, and clean between them. This will reduce potential skipping issues and other problems because thread, lint, or other debris can get in between the plates and cause stitching errors.

A Final Word on Cleaning Your Sewing Machine

Essentially, anywhere that thread runs within your Class 7 sewing machine should be cleaned out so that it is lint-free. This allows your oil to get where it needs to go to properly lubricate every part of the machine. 

Daily and weekly maintenance of your machine is also crucial to troubleshooting, as it makes it easier to see where there might be an issue.
