Maintenance
Regular maintenance ensures the longevity and optimal performance of your SINGER S14-78 Serger.
Cleaning
After each use, remove lint and thread scraps from the looper area, under the needle plate, and around the feed dogs using a lint brush. Periodically, open the side cover to clean any accumulated lint from the internal mechanisms. Avoid using compressed air, as it can push lint further into the machine.
Lubrication
Refer to the official user manual for specific lubrication points and recommended oil. Generally, a few drops of high-quality sewing machine oil are applied to moving metal parts as indicated in the manual.
Needle Replacement
Replace needles regularly, especially when working on new projects or if stitches appear uneven. Use SINGER® Overlock needles #2022, size #14/90, as specified. Use the provided Allen key for needle changes.
