CLEANING
IMPORTANT: For best performance,
keep trimmer free of built-up grass and
trash. Clean the underside of your
tdmmer after each use.
A.CAUTtON: Disconnect spark plug wiru
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-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 garder
hose to clean trimmer unless the
electrical system, muffler, air filter and
carburetor are covered to keep water
out. Water in engine can result in
shortened engine life.
