MAINTENANCE

Winter use

During cold weather and under powder snow conditions, operating problems can arise due to:

•Too low engine temperature.

•Icing of the air filter and carburettor. Special measures are therefore often required:

•Partly mask the air inlet on the starter to increase the working temperature of the engine.

Temperature 0° C (32° F) or colder:

The cylinder cover is designed so it can be adjusted for running in cold weather. Twist the winter flap so that preheated air from the cylinder can pass into the carburettor space preventing icing of the air filter, etc.

Temperature -5°C (23° F) or colder:

For temperatures below -5°C and/or in snow conditions there is also:

•a special cover (A) for the starter housing

•a winter plug (B) for the air nozzle that is fitted as shown.

H

These reduce the flow of cooling air and prevent large amounts of snow from being sucked into the carburettor space. CAUTION! When the winter plug is fitted the winter flap must be open!

IMPORTANT! 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 machine is used in normal temperature conditions. Otherwise there is a risk of overheating, 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 (retailer).

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

2Clean the chain brake and check that it operates safely. Make sure that the chain catcher is undamaged, and replace it if necessary.

3Clean the air filter. Replace if necessary.

4The 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.

5Check that the bar and chain are getting sufficient oil.

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

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

8Check that nuts and screws are tight.

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

10Check the cooling system on chain saws with catalytic converters.
