During winter time, powder snow and cold weather can cause running problems, such as:

Too low engine temperature.

Icing on the air filter and carburetor.

Therefore some special measures are required:

Partly reduce the air inlet of the starter and by doing that increase the engine temperature.

Preheat the intake air to the carburetor by removing the special plug between the cylinder and the carburetor space.

Temperature 0oC (32oF) or colder

Twist the cover flap so that preheated air from the cylinder can enter the carburetor chamber to prevent icing of the filter.

Temperature -5oC (23oF) or colder

When using the saw in cold weather or powder snow conditions you should cover the starter unit with adhesive

Cooling system

To obtain the lowest possible running temperature the saw is equipped with a cooling system.

tape. This reduces the flow of cold air and prevents large amounts of snow from being sucked in.

The cooling system consists of:

1.Air intake on the starter unit.

2.Air guide plate.

increase the engine temperature, a readjustment to normal setting has to be done when the saw is used under normal conditions. Otherwise, there is a risk of overheating, which can cause severe engine damage.

IMPORTANT! Any maintenance other than that described in this manual must be carried out by your servicing dealer.

Clean the cooling system with a brush once a week, more often in demanding conditions. A dirty or blocked cooling system results in the saw overheating which causes damage to piston and cylinder.
