MAINTENANCE

Cooling system

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

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

Daily maintenance

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.

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.

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 the air filter and the area around the carburettor. Replace the air filter if necessary.

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 and lubricate the bar sprocket tip.

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.
