GAS
,
Fill gasoline tank with fresh, clean, unleaded gasoline.
DO NOT USE PREMIUM GASOLINE, BE CAREFUL
NOT TO OVER FILL TANK.
WARNING:
Experience indicates that alcohol blended
fuels (called gasoho! 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 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 lnstructions for additional information. Never use engine or
carburetor cleaner products in fuel tank or permanent
damage may occur.

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.
Push engine speed control lever to fast (_) 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.
MAX 113
NOTE: In cooler weather it may be necessary to repeat
priming steps. 1n 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 priming steps.

MULCHING
MOWING TIIPS
o
*
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 better grass bagging and most cutting conditions,
the engine speed should be set in the fast ('_)
position.
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.

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 speciat mulching blade will recut the grass clippings 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 wilt
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.
•
tf a trail of grass clippings is left on the 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.
Keep top of engine around starter clear and clean of
grass clippings and chaff. This will help engine air
flow and extend engine life.
Pores in cloth grass catchers can become filled with
dirt and dust with use and catchers will collect tess
grass. To prevent this, regularly hose catchers off
with water and let dry before using.
•
10
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 tawn 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 tawn mower cutting height
so that the lawn mower cuts off only the top one-third
of the grass blades (See Fig. 8). 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
require that an area be mulched a second time to
completely 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 wilt help prevent matting and
graining of the lawn.

NOTE: Although multi-viscosity oils (5W30, 10W30 etc.)
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 if the lawn
mower is not used for 25 hours in one year.
Check the crankcase oil level before starting the engine
and after each five (5) hours of continuous use. Tighten oil
plug securely each time you check the oil level.

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 garden hose to clean
lawn mower unless the electrical system, muffler, air
filter and carburetor are covered to keep water out.
Water in engine can result in shortened engine life.

Your carburetor has a non-adjustable fixed main jet for
mixture control. If your engine does not operate properly
due to suspected carburetor problems, take your lawn
mower to an authorized service center for repair or adjustment,
Your engine speed has been factory set. Do not attempt
to increase engine speed or it may result in personal
injury. If you believe that the engine is running too fast or
too stow, take your lawn mower to an authorized service
center for repair and adjustment.

STORAGE
immediately prepare your lawn mower for storage at the
end of the season or if the unit wilt not be used for 30 days
or more.

IT ]S IMPORTANT TO PREVENT GUM
DEPOSITS FROM FORMING tN 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
METHANOL) CAN ATTRACT MOISTURE WHICH LEADS
TO SEPARATION AND FORMATION OF ACIDS DURING
STORAGE.
AC_D1C GAS CAN DAMAGE THE FUEL
SYSTEM OF AN ENGINE WHILE IN STORAGE.
•
Drain the _uel tank.
LAWN MOWER
When lawn mower is to be stored for a period of time, clean
it thoroughly, remove all dirt, grease, leaves, etc. Store in
a clean, dry area.
,
Clean entire lawn mower (See "CLEANING" in the
Customer Responsibilities section of this manual).
Lubricate as shown in the Customer Responsibilities
section of this manual.
•
Be sure that all nuts, bolts, screws, and pins are
securely fastened. Inspect moving parts for damage,
breakage and wear. Replace if necessary.
•
Touch up all rusted or chipped paint surfaces; sand
lightly before painting.
HANDLE
•
Never use engine or carburetor cleaner products in the
fuel tank or permanent damage may occur.
Use fresh fuel next season.
(See Fig. 15)
NOTE:
Fuel stabilizer is an acceptable alternative in
minimizing the formation of fuel gum deposits during storage. Add stabilizer to gasoline in fuel tank or storage
container. Always follow the mix ratio found on stabilizer
container. Run engine at least t0 minutes after adding
stabilizer to allow the stabilizer to reach the carburetor. Do
not drain the gas tank and carburetor if using fue! stabilizer.
You can fold your lawn mower handle for storage.
,
Start the engine and let it run until the fuel lines and
carburetor are empty.
Squeeze the bottom ends of the lower handle toward
each other until the lower handle clears the handle
bracket, then move handle forward,
•
Loosen upper handle mounting bolts enough to allow
upper handle to be folded back.
IMPORTANT,
WHEN FOLDING THE HANDLE FOR
STORAGE OR TRANSPORTATION, BE SURE TO FOLD
THE HANDLE AS SHOWN OR YOU MAY DAMAGE THE
CONTROL CABLES.
