MAINTENANCE

Cooling system

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

system.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).

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 ”Turbo”

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.

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. 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.

Electrically heated handles or carburetor

Electrically heated handles or carburetor receive their current from an alternator built into the flywheel. The current is controlled by an ON/OFF/ ON switch.

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