MACHINE MAINTENANCE
An overlock machine requires more maintenance than
a conventional machine for two reasons:
1. A lot of lint is produced due to the cutting action
of the knives.
2. An overlock runs at a very high speed and needs
to be oiled frequently to lubricate the internal
working parts.

– Clean the lint from the looper and knife area
