MAINTENANCE

!WARNING!

The one-man sawmill must be disconnected from power during all maintenance work. Always use personal protective equipment.

Clutch drum

When replacing the clutch drum on the chain saw, see the chain saw operator’s manual.

The clutch drum on the chain sawmill with electric motor has a setscrew installed in the end of the drive shaft. The task of the screw is to prevent the clutch drum from unscrewing in the event the sawmill is started in the wrong direction. CAUTION! The screw and its washer must be unscrewed before the clutch drum can be removed. The clutch drum has left-hand threads.

The clutch drum is equipped with ring sprockets (replaceable). The clutch drum has a needle bearing on the output shaft, which has to be greased regularly (once a week). CAUTION! Use only high quality bearing grease.
