the brush retainer.

check that they slide easily in the brush retainers.

Gearbox 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.
Use high quality gear grease.
The following parts must be dismantled to change the
grease in the gear housing:
•
Flange washers holding the cutting blade
•
The sealing ring
•
Support flange for the guard
•
Blade guard
•
The four screws holding the shield. Lift the shield
together with the drive wheel unit out of the gear
housing.
•
Wipe out the grease and fill with new, good quality
gear grease. The gear housing should contain 90 g of
grease in total.
NOTICE! Exercise care when dismantling so as not to
damage the gaskets. These are used both as seals and
spacers for the gear setting.
