_LCAUTION: Disconnect spark plug wire
from spark plug and place wire where it
cannot come in contact with plug.
• 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 electri-
cal system, muffler, air filter and car-
buretor are covered to keep water out.
Water in engine can result in shortened
engine life.
WARNING: To avoid serious injury,
before performing any service and
adjustments:
1. Stop engine.
2. Make sure the rotating lines and
all moving parts have completely
stopped.
3. Disconnect spark plug wire from spark
plug and place wire where it cannot
come in contact with plug.
