MAINTENANCE
Bevel gear
The grease in the gear housing should be changed every 4
months. Use high quality gear grease
The gear housing must not be filled completely with grease.
The grease expands as the machine heats up during
operation. If the gear housing was completely filled with
grease it could damage the seals and lead to leakage of
grease.
The gear housing should contain 90 g of grease in total.
Changing the grease
The following parts must be dismantled to change the grease
in the gear housing:
1 Flange washers holding the cutting blade
2 The sealing ring
3 Support flange for the guard
4 Guard for the blade
5 The four screws holding the shield. Lift the shield together
with the drive wheel unit out of the gear housing.
6 Wipe out the grease and fill with new, good quality gear
grease. The gear housing should contain 90 g of grease
in total.
CAUTION! Exercise care when dismantling so as not to
damage the gaskets. These are used both as seals and
spacers for the gear setting.
Checking the drive axle and flange
washers
Check that the threads on the drive shaft are undamaged.
Check that the contact surfaces on the blade and the flange
washers are undamaged, of the correct dimension, clean,
and that they run properly on the drive axle.
