curs fi rst. Service air cleaner more often

4. Insert and tighten dipstick.
IMPORTANT:
• Check oil level before each use. Add oil
if needed. Fill to full line on dipstick.
• Change the oil after every 25 hours of
operation or each season. You may
need to change the oil more often under
dusty, dirty conditions.

ADD GASOLINE

• Fill fuel tank to bottom of tank fi ller neck.
Do not overfi ll. Use fresh, clean, regular
unleaded gasoline with a minimum of 87
octane. Do not mix oil with gasoline. Pur-
chase fuel in quan ti ties that can be used
within 30 days to assure fuel freshness.
CAUTION: Alcohol blended fuels
(called gasohol or using ethanol or
methanol) can attract moisture which
leads to separation and for ma tion of acids
during storage. Acidic gas can damage
the fuel system of an engine while in
storage. To avoid engine problems, the
fuel system should be emptied before
stor age of 30 days or longer. Drain
the gas tank, start the engine and let it
run until the fuel lines and carburetor
are empty. Use fresh fuel next season.
See Storage In struc tions for additional
information. Never use engine or
carburetor cleaner products in the fuel
tank or permanent damage may occur.
CAUTION: Wipe off any spilled oil or
fuel. Do not store, spill or use gasoline
near an open fl ame.

Primer
TO STOP ENGINE
• To stop engine, move throttle control
lever to STOP position.
TO START ENGINE
1. To start a cold engine, push primer three
(3) times before trying to start. Use a fi rm
push. This step is not usually neces-
sary when starting an engine which has
already run for a few minutes.
2. Move throttle control lever to FAST
position.
3. Hold upper handle fi rmly and pull
starter handle quickly. Do not allow
starter rope to snap back.
NOTE: In cooler weather it may be
necessary to repeat priming steps. In
warmer weather overpriming may cause
fl ooding and engine will not start. If you
do fl ood engine, wait a few minutes before
attempting to start and DO NOT repeat
priming steps.

TRIMMING TIPS

• Set the throttle control in the FAST posi-
tion. If the weeds or grass are tall and
thick, operate the trimmer at a slower
walking speed.
• Frequently clean the underside of the
trimmer to remove any grass build up.
Keep top of engine around starter clear
oil cap
and clean of grass clippings and chaff.
This will help engine air fl ow and extend
engine life.
• For best results and longer lasting
line, use the ends of the line to do the
cutting. This is easily done by moving
slowly through very thick and heavy
weeds.
• Use the left side of trimmer when trim-
ming along fences, walls, fl owerbeds
and other such objects.
• If trimmer lines become too short, it will
take longer to complete the job. If trim-
mer lines are worn to less than half their
original length, they should be replaced.
See "TO REPLACE TRIMMER LINE" in
the Maintenance section of this manual.
• Trimmer head contact with concrete, as-
phalt or other hard surfaces may cause
premature wear of the ball on bottom of
trimmer head.
