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
op er a tion or every season, which ev er 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 dam age.
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
elec tri cal system, muffl er, air fi lter and
carburetor are covered to keep water
out. Water in engine can result in short-
ened engine life.
CLEAN UNDER ENGINE COVER

Clean under engine cover before each
use, or more frequently in heavy cutting or
dirty conditions. Engine cover screen and
engine air intake screen must be kept free
of dirt and chaff to prevent engine damage
from over heat ing.

ough ly.
