28. 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.
