Lubricating the bar tip sprocket
Lubricate the bar tip sprocket each time you refuel. Use the
special grease gun and a good quality bearing grease.
Needle bearing lubrication
The clutch drum has a needle bearing on the output shaft.
This needle bearing must be lubricated regularly (once a
week). CAUTION! Use only 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:
Bar -15":
1 turn from the closed position.
Bar 15" -18":
2 turns from the closed position.
Bar 18" -24":
3 turns from the closed position.
Bar 24" -:
4 turns from the closed position.
These recommendations apply to Husqvarna's chain oil, for
other chain oils increase the oil flow by one step.
WARNING! The engine must not be running

MAINTENANCE
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
carburetor 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 carburetor compartment.
Winter use
Running problems can occur when using the machine in the
cold and snowy conditions caused by:
•
Too low engine temperature.
•
Icing of the air filter and carburetor.
Special measures are therefore often required:
•
Partly mask the air inlet on the starter to increase the
working temperature of the engine.
