the body coming into contact with the blades (B).
A
B
• Check that the hand guard is fitted correctly.
• Check that the hand guard is undamaged.
Blades
To ensure good cutting results it is important that the contact
pressure between the blades is correct. The contact pressure
is adjusted by turning the screws on the underside of the bar
clockwise as far as they will go. Then turn the screws
anticlockwise a 1/4 turn. Lock the screws using the locking nut
on the top of the bar. Check that the screws are loose enough
to allow the washers under the screw heads to slide sideways.
4 – English
When the blades are correctly adjusted the play between the
blades should be 0,2–0,4 mm, measured at the screws.
The edges of the blades are too hard to be filed. Dull blades
should be sharpened using a grinder.
Replace the blades if they are bent or damaged.

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.
Maintenance schedule
Below you will find some general maintenance instructions. If
you need further information please contact your service
workshop.
Daily maintenance
1 Check that the blades do not move when the engine is
idling or when the choke is in the start throttle position.
2 Check that the hand guard is not damaged. Replace the
guard if damaged. (HA 110)
Weekly maintenance
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.
1 Fill the gear housing with grease. This should be carried
out approximately every 20 working hours.
2 Check that the screws that hold the blades together are
correctly tightened.
