AIR FILTER

Your engine will not run properly and may be damaged by using a dirty air fi lter. Replace the air fi lter every 100 hours of operation or every season, whichever oc- curs fi rst. Service air cleaner more often under dusty conditions. Do not wash air fi lter. Refer to engine manual.

MUFFLER

Inspect and replace corroded muffl er as it could create a fi re hazard and/or damage.

SPARK PLUG

Change your spark plug each year to make your engine start easier and run better. Set spark plug gap according to engine manual specifi cations.

CLEANING

IMPORTANT: For best performance, keep trimmer free of built-up grass and trash. Clean the underside of your trimmer after each use.

CAUTION: Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with the spark plug.

Turn trimmer on its side. Make sure air fi lter and carburetor are up. Clean the underside of your trimmer by scraping to remove build-up of grass and trash.

Clean engine often to keep trash from accumulating. A clogged engine runs hotter and shortens engine life.

Keep fi nished surfaces and wheels free of all gasoline, oil, etc.

We do not recommend using a gar- den hose to clean trimmer unless the electrical system, muffl er, air fi lter and carburetor are covered to keep water out. Water in engine can result in short- ened engine life.
