Replacing the carbon brushes
Check the carbon brushes at least once a month. The

they are worn, cracked or in any other way deformed.
All carbon brushes must be replaced when the brushes
are replaced.

up the spring and then lift out the carbon brush from
the brush retainer.
•
Clean the brush retainers with a dry brush.
•
Carefully blow away the dust.
•
Fit the new carbon brushes and, at the same time,
check that they slide easily in the brush retainers.
•
Fold down the springs and tighten the cable.
•
New carbon brushes must be run in for approximately
40 minutes while idling.
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 shaft 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.
Do not use warped, notched, indented or dirty flange
washers. Do not use different dimensions of flange
washers.
