Always use HUSQVARNA �lter oil, art. no. 531 00 92-48. The �lter oil contains a solvent to make it spread evenly through the �lter. You should therefore avoid skin contact. Put the �lter in a plastic bag and pour the �lter oil over it. Knead the plastic bag to distribute the oil. Squeeze the excess oil out of the �lter inside the plastic bag and pour off the excess before �tting the �lter to the machine. Never use common engine oil. This would drain through the �lter quite quickly and collect in the bottom.
Clean any resin and plant residue from the blades using cleaning agent 531 00 75-13 (UL22) before and after using the machine. Lubricate the blade bars with special grease, part no. 531 00 75-12 (UL 21) before long periods of storage.
Gear housing
There is a grease nipple and a plug for �lling lubricant on the gear housing. Use a grease gun to �ll with grease. This should be done after every 60 working hours. Use Husqvarna�s special grease, no. 503 98 96-01.
CAUTION! The gear housing must not be �lled completely with grease. The grease expands as the machine heats up during operation. If the gear housing was completely �lled 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.
