MAINTENANCE

Cooling system

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

Winter use

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.

The cooling system consists of:

1.Air intake on the starter unit.

2.Air guide plate.

3.Fan blades on the flywheel.

4.Cooling fins on the cylinder.

5.Cylinder cowling (supplies cold air over the cylinder).

Therefore some special measures are required:

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

Temperature -5°C or colder:

For running the saw in cold weather or powder snow, a special cover is available, which is mounted on the starter housing. This reduces the air flow and

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.

Centrifugal cleaning ”Air Injection”

Centrifugal cleaning means the following:

All air to the carburetor is carried through the starter. Dirt and dust is centrifuged away by the cooling fan.

IMPORTANT! In order to keep the function of the centrifugal cleaning, a continous maintenance and care must be made.

Clean the air intake to the starter, the fan wings of the

flywheel, the space around the flywheel, inlet pipe and carburetor space.

prevents large amounts of snow from being sucked in.

NOTE! If the special winterising kit has been fitted or any measures have been taken to increase the temperature these changes must be reversed before the saw is used in normal temperature conditions. Otherwise there is a risk that the saw will overheat, resulting in severe damage to the engine.

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