MAINTENANCE
Gear housing
There are three grease nipples on the gear housing. Use a
grease gun to top up with grease. This should be carried out
approximately every 20 working hours. Use Husqvarna
special grease, part no. 503 98 96-01.
CAUTION! 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 grease in the bevel gear does not normally need to be
changed except if repairs are carried out.
Cleaning and lubrication
After you have used the machine clean any resin and plant
residue from the blades using cleaning agent 531 00 60-75
(UL22).
Always lubricate the blade bars with special grease, part no.
531 00 60-74 (UL 21) before use.
