Needle bearing lubrication
The clutch drum has a needle bearing on the output shaft.
This needle bearing must be lubricated regularly (once a
week). NB! Use a high-quality bearing grease or engine
oil. See instructions under the heading Cutting
equipment.
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.
”Air Injection” centrifugal
cleaning
Centrifugal cleaning means the following: All air to the
carburettor passes through the starter. Dirt and dust is
centrifuged out by the cooling fan.
IMPORTANT! In order to maintain operation of the
centrifugal cleaning system it must be regularly
maintained. Clean the air intake to the starter, the fins on
the flywheel, the space around the flywheel, inlet pipe and
carburettor compartment.
