WARNING: Experience indicates that alcohol blended
fuels (called gasohol or L_singethanol 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 stor-
age of 30 days or longer,. Drain the fuel tank, start the
engine and let it run until fuel lines and carburetor are
empty. Use fresh fuel next season See Storage Instruc-
tions for additional information Never use engine or
carburetor cleaner products in fuel tank or permanent
damage may occur.
TO START ENGINE
o 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 already
run for a few minutes.
° Move engine speed control lever to high ('_) position,
Hold operator presence control bar' down to the 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 Inwarmerweatherover priming maycause
flooding and engine will not start. If you do flood engine wait
a few minutes before attempting to start and do not repeat
priming steps.
OPERATION
MOWING TIPS
• Undercertain 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 better grass bagging and most cutting conditions,
the engine speed should be set in the high ('_) posi-
tion.
• When using a rear discharge lawn mower in moist,
heavy grass, clumps of cut grass may not enter the
grass catcher, Reduce ground speed (pushing speed)
and/or run the lawn mower over the area a second time,
• If atraitof grassclippingsisleft onthe right side of a rear
discharge lawn mower, mow in a clockwise direction
with a small overlap to collect the clippings on the next
pass.
• Pores in cloth grass catchers can become filled with dirt
and dust with use and catchers will collect less grass.
Toprevent this, regularly hose catcher off with water
andlet dry before using.
• Keep top of engine around starter clear and clean of
grass clippings and chaff_ This will help engine air flow
and extend engine life.

FIG. 13
MULCHING MOWING TIPS
IMPORTANT: FOR BEST PERFORMANCE, KEEP
MOWER HOUSING FREE OF BUILT-UP GRASS AND
TRASH SEE "CLEANING" IN CUSTOMER
RESPONSIBILITIES SECTION OF THIS MANUAL
The special mulching blade will recur the grass clip-
pings many times and reduce them in size so that as
they fall onto the lawn they will disperse into the grass
and not be noticed Also, the mulched grass will
biodegrade quickly to provide nutrients for the lawn.
Always mulch with your highest engine (blade) speed
as this will provide the best recutting action of the
blades
Avoid cutting your lawn when it is wet Wet grass tends
to form clumps and interferes with the mulching action.
The best time to mow your lawn is the early afternoon
At this time the grass has dried and the newly cut area
will not be exposed to the direct sun
° For best results, adjust the lawn mower cutting height
so that the lawn mower cuts off only the top one-third
of the grass blades (See Fig. 13) If the lawn is
overgrown it will be necessary to raise the height of cut
to reduce pushing effort and to keep from overloading
the engine and leaving clumps of mulched grass. For
extremely heavy mulching, reduce your width of cut,
mow slowly and raise the rear of the lawn mower one
wheel adjuster setting higher than the front.
• Certain types of grass and grass conditions may re-
quire that an area be mulched a second time to com-
pletely hide the clippings. When doing a second cut,
mow across or perpendicular to the first cut path
° Change your cutting pattern from week to week. Mow
north to south one week then change to east to west the
next week 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 frequently to avoid
possible engine 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 ifthe lawn

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
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
fuel tank or permanent damage may occur.

minimizing the formation of fue_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
stabilizer to allowthe stabilizer to reachthecarburetor. Do
