Needle bearing lubrication
The clutch drum is fitted with one of the following drive
sprockets:
A Spur sprocket (the chain sprocket is welded on the
drum)
B Rim sprocket (replaceable)
Both versions have a needle bearing on the drive
shaft, which has to be greased regularly (once a
week).
NOTE! Use only high quality bearing grease or engine oil.
Adjustment of the oil pump
The oil pump is adjustable. Adjustments are made by
turning the screw using a screwdriver or combination
spanner. The machine is supplied from the factory set to
1 turn open. Turning the screw clockwise will reduce the
oil flow and turning the screw anti-clockwise will increase
the oil flow.
Recommended settings:
These recommendations apply to Husqvarna’s chain oil,
for other chain oils increase the oil flow by one step.
Cooling system
To keep the working temperature as low as possible the
machine is equipped with a cooling system.
The cooling system consists of:
1 Air intake on the starter.
2 Air guide plate.
3 Fins on the flywheel.
4 Cooling fins on the cylinder.
5 Cylinder cover (directs cold air over the cylinder).
Clean the cooling system with a brush once a week, more
often in demanding conditions. A dirty or blocked cooling
system results in the machine overheating which causes
damage to the piston and cylinder.
!
WARNING! The engine must be stopped
when making adjustments.
