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
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
Always lubricate the blade bars with special grease, part no. 531 00
