MAINTENANCE
Bevel gear
The bevel gear is filled with the right quantity of grease at the
factory. However, before using the machine you should check
that the bevel gear is filled three-quarters full with grease. Use
HUSQVARNA special grease.
The grease in the bevel gear does not normally need to be
changed except if repairs are carried out.
