SERVICE AND ADJUSTMENTS
• Turn trimmer on its side. Make sure air
filter 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 finished surfaces and wheels free
of all gasoline, oil, etc.
• We do not recommend using a garden
hose to clean trimmer unless the elec tri-
cal system, muffler, air filter and car-
buretor are covered to keep water out.
Water in engine can result in shortened
engine life.
