MAINTENANCE
Below you will find some general maintenance
instructions.
Daily maintenance
1 Check 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, 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 that it operates safely.
Make sure that the chain catcher is undamaged, and
replace it if necessary.
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.
