24. MACHINE MAINTENANCE

An overlock requires more maintenance than a
conventional machine mainly due to 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.

Cleaning the Machine

Danger:
Before cleaning your machine, disconnect
power line plug from the wall receptacle.
• Clean the lint from the looper and knife area often
with a dry lint brush.
Note: Lint brush is an optional part.

Oiling the Machine

Danger:
Before lubricating your machine, disconnect
power line plug from the wall receptacle.
• The oiling points shown in the diagram, should be
oiled periodically.
Note: Use sewing machine oil. Do not use any
other oil or damage could result.
