AIR FILTER
Your engine will not run properly and may
be damaged by using a dirty air filter.
Replace the air filter every 100 hours of
operation or every season, whichever oc-
curs first. Service air cleaner more often
under dusty conditions. Do not wash air
filter. Refer to engine manual.
MUFFLER
Inspect and replace corroded muffler as it
could create a fire hazard and/or damage.
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 specifications.
CLEANING
IMPORTANT: For best performance,
keep trimmer free of built-up grass and
trash. Clean the underside of your trimmer
after each use.
• ilCAUTION: 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-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 gar-
den 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 short-
ened engine life.
CLEAN UNDER ENGINE COVER

use, or more frequently in heavy cutting or
dirty conditions. Engine cover screen and
engine air intake screen must be kept free

oughly.
