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.

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.

Note! The cooling system on a chain saw with catalytic 
converter must be cleaned daily. This is particularly 
important on chain saws with catalytic converters, 
because the higher exhaust temperature requires 
efficient cooling of the engine and the catalytic converter 
unit.

Centrifugal cleaning means the following: All air to the 
carburetor passes through the starter. Dirt and dust is 
pushed 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.

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:

•

Preheat the intake air to the carburetor by using the 
heat from the cylinder.

•

Partly mask the air inlet on the starter to increase the 
working temperature of the engine.
