WARNING: Experience indicates that alcohol blended
fuels (called gasohol or using ethanol or methanol) can
attractmoisture whichleads toseparation andformation 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
emptiedbefore storagefor 30 days or longer. Drainthe gas
tank, star_the engine and let it run untiltile fuel lines and
carburetor are empty. Use fresh fuel next season. See
Storage instructionsfor additional information.
Never useengineorcarburetor cleaner productsinthe fuel
tank or permanent damage may occur.

OPERATIC
TO START ENGINE
- To start a cold engine, push primerfive (5) times before
trying to starL Use a firm push,. This step is not usually
necessary when starting an engine which has already
run for a few minutes°
• Push engine speed control lever to HIGH position,
° Hold operator presence control bar down tothe handle
and pull 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
floodingand engine wil! not start. Ifyoudoflood enginewait
a few minutes before attempting to start and DO NOT
repeat priming steps.
MOWING TIPS
• Undercertain conditions, suchasvery 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 thanthe front for better
discharge of grass°
° For side discharge mowers, cutting ina counter-clock-
wise direction, starting at the outside of the area to be
cut, spreads grass clippings more evenly and puts less
load on the engine. To keep clippingsoff 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 will help engine air flow
and extend engine life.

MULCHING MOWING TIPS
IMPORTANT: FOR BEST PERFORMANCE, KEEP
MOWER HOUSING FREE OF BUILT-UP GRASS AND
TRASH. CLEAN UNDERSIDE OF MOWER HOUSING
AFTER EACH USE. SEE "CLEANING" IN CUSTOMER
RESPONSIBILITIES SECTION OF THIS MANUAL.
° The special mulching blade will recut the grass clip-
pings many times and reduce them in size so that as
theyfall onto the lawnthey willdisperse into the grass
and not be noticed. Also, the mulched grass will
biodegrade quickly to provide nutrients for the lawn.
Always mulch withyour highestengine (blade) speed
as this will providethe best recutting action of the
blades.
- Avoidcuttingyourtawnwhenitisweto Wet grass tends
toform clumpsandinterfereswith themulching action.
The best time to mow your lawn isthe early afternoon.
At thistime the grasshas dried and the newly cutarea
willnot be exposed to the direct sun.
- For best results,adjust the lawn mower cutting height
sothat the lawn mower cuts off only the top one-third
of the grass blades (See Fig. 7). If the lawn is
overgrownitwillbe necessary to raise the heightof cut
to reducepushingeffortand to keep from overloading
the engine and leaving clumps of mulched grass. For
extremely heavy mulching, reduce your width of cut,
mow slowlyand raise the rear of the lawn mower one
wheel adjuster setting higher than the front.
o Certain types of grass and grass conditions may re-
quire that an area be mulched a second time to com-
pletely hidethe clippings. When doing a second cut,
mow across or perpendicularto the first cut path°
° Change your cuttingpattern from week to week. Mow
northto south one week thenchange to eastto west the
nextweek° This will help prevent matting and graining
of the lawn.

improve starting in cold weather, these multi-viscosity oils
will result in increased oil consumption when used above
32°F. Check your engine oil level more frequentlyto avoid
possibleengine damage from running low on oil.
Change the oil after the first two hours of operation and
every 25 hours thereafter or at least once a year if the lawn
mower is not used for 25 hours in one year.
Check tile crankcase oil level before starting the engine

SYSTEM PARTSSUCH AS CARBURETOR, FUEL FILTER,
FUEL HOSE, OR TANK DURING STORAGE. ALSO,
EXPERIENCE ffqDtCATES 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°
• Drain the fuel tank_
• Start the engine and let it run until the fuel lines and
carburetor are empty.
• Never' use engine or carburetor cleaner products in the

minimizing the formation of fuel gum deposits during stor-
age° Add stabilizer to gasoline in fuel tank or storage
container. Always follow the mix ratio found on stabilizer
container. Run engine at least 10 minutes after adding
stabilizerto allowthe stabilizer to reach the carburetor. Do
not drain the gas tank and carburetor if usingfuel stabilizer.
