CLEANING
IMPORTANT: For best performance,
keep tdmmer free of built-upgrass and
trash. Clean the underside of your
tdmmer after each use.
ACAUTION: 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
filter and carburetor are up. Clean the
underside of your trimmer by scraping
to remove build-upof 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 usinga garden
hose to clean trimmer unless the
electdcal system, muffler, air filter and
carburetor are covered to keep water
out. Water in engine can result in
shortened engine life.
