MAINTENANCE

Cooling system

Below you will find some general maintenance instructions. If you have more questions, contact your servicing dealer.

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.

Daily maintenance

1.Check the throttle trigger for smooth operation. If any binding occurs, or if engine fails to return to idle, the saw should be taken to your dealer, before it is used again. Also, be sure that the trigger cannot be pulled until the throttle trigger lockout is depressed.

2.Clean the chain brake and check its function according to the instructions. Make sure that the chain catcher is undamaged. Otherwise replace it immediately.

3.Clean or replace the air filter as necessary. Check for damage or holes.

4.The bar should be turned daily for more even wear. Check the lubrication hole in the bar, to be sure it is not clogged. Clean the bar groove, if the bar has a sprocket tip, this should be lubricated.

5.Check the function of the oiler to be sure the bar and chain receive proper lubrication.

6.Sharpen the chain and check its tension and condition. Check the drive sprocket for wear. Replace if necessary.

7.Check the starter and starter cord for wear or damage. Clean the air intake slots on the starter housing.

8.Check for any loose nuts and screws and retighten if necessary.

9.Test the stop switch to be sure it shuts off the engine.
