MAINTENANCE

Gear housing

There is a grease nipple on the gearbox. Use a grease gun to top up with grease. This should be carried out after approximately every 20 working hours. Use Husqvarna special grease, 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.
