GAS (See Fig. 5)
•

Fill gasoline tank with fresh, clean unleaded gasoline.
DO NOT USE PREMIUM GASOLINE. BE CAREFUL
NOT TO OVERFILL TANK.

WARNING: Experience indicates that alcohol blended
fuels (called gasohol or using ethanol or methanol) can
attract moisture which leads to separation and formation 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 storage for 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 instructions for additional information.
Never use engine or carburetor cleaner products in the fuel
tank or permanent damage may occur.

•

TO START ENGINE
°

To start a cold engine, push primer five (5) times
before trying to start. Use a firm push. This step is not
usually necessary when starting an engine which has
atready run for a few minutes.
Hold operator presence control bar down to the handte
and putt starter handle quickly. DO NOT allow starter
rope to snap back.
To STOP engine, release operator presence control
bar.

NOTE: In cooler weather it may be necessary to repeat
priming steps. In warmer weather over priming may cause
flooding and engine will not start, If you do flood engine,
wait a few minutes before attempting to start and DO NOT
repeat primintg steps.

TiPS

Under certain conditions, such as very tall grass, it may
be necessary to raise the height of cut to reduce
pushing effort and to keep from overloading the engine
and leaving clumps of grass clippings.
For extremely heavy cutting, reduce the width of cut
and raise the rear of the lawn mower housing one (1)
wheel adjuster setting higher than the front for better
discharge of grass.
For side discharge mowers, cutting in a counter-clock
wise direction, starting at the outside of the area to b_.
cut, spreads grass clippings more evenly and puts less
load on the engine. To keep clippings off of walkways,
flower beds, etc., make the first cuts in a clockwise
direction.
Keep top of engine around starter clear and clean of
grass clippings and chaff. This wilt help engine air flow
and extend engine life.

iMPORTANT:
IT IS iMPORTANT TO PREVENT GUM
DEPOSITS FROM FORMING iN ESSENTIAL FUEL
SYSTEM PARTS SUCH AS CARBURETOR, FUEL FILTER,
FUEL HOSE, OR TANK DURING STORAGE.
ALSO,
EXPERIENCE INDICATES THAT ALCOHOL BLENDED
FUELS (CALLED GASOHOL OR USING ETHANOL OR

TO SEPARATION AND FORMATION OF ACIDS DURING
STORAGE.
ACIDIC GAS CAN DAMAGE THE FUEL
SYSTEM OF AN ENGINE WHILE IN STORAGE.
