BEFORE STARTING ENGINE
OIL
Your lawn mower is shipped wi_out oil in the
engine.
• Be sure mower is level and area around oil
fill is clean.
• Remove engine oil cap and _ll to the full
line on the dipstick.
NOTE: Allow oil to settle down into
engine for accurate dipstick reading.
Engine holds 20 ozs. ot oi!. For type and
grade of oil to use, see "ENGINE" in
Maintenance section of this manual.
• Pour oil slowly. Do not over fill.
• Check oil level before each use. Add oil if
needed. Fill to full line on dipstick.
• To read proper level, _ghten engine oil cap
each time.
• Reinstall engine oil cap and tighten.
• Change the oil after every 25 hours of
operation or each season. You may need
to change the oil more o_tan under dusty,
dirty conditions.

GAS
NOTE: Before fillingfuel tank, remove and
discard the debris plug that is inside the tank.
• Fill fuel tank. Use fresh, dean, regular
unleaded gasoline with a minimum of 87
octane. Do not mix oil with gasoline.
Purchase fuel in quantities that can be
used within 30 days to assure fuel
fi'eshness.
_WARNING:
Experience indicates that
hoi blended fuels (called gasohol or
using ethanol or methanol) can attract
moisture which leads to separation and
formatJan of acids during storage. Acidic gas
can damage the _
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 unUl 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 fuel tank or
permanent damage may occur.

run for a few minutes.
• 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. In warmer weather
over priming may cause flooding and engine
will not start. If you do flood engine, wait a few
minutes before attem_ng to start and do not
repeat priming steps.

MOWINGTIPS

MULCHING MOWING 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. It may
also be necessary to reduce ground speed
and/or run the lawn mower over the area a
second time.

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
MAINTENANCE section of this manual.
• The special 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 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 aftemoon. 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. If the lawn is overgrown it will be
necessary to raise the height of cut to
reduce pushing effort and to keep from
overloeding 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

• For extremely heavy cutting, reduce the
width of cut by overlapping previously cut
path and mow slowly.
• For better grass bagging and most cutting
conditions, the engine speed should be set
in the fast position.
• Pores in cloth grass catchers can become
filled with dirt and dust with use and
catchers will collect less grass. To prevent
this, regularly hose catcher off with water
and let 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.

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 pattem 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.

TOASSEMBLE GRASS CATCHER
• Put grass catcher frame into grass bag
with rigid part of bag on the bottom.
Make sure the frame handle is outside

CAUTION:
Do not run your lawn mower
without clipping deflector or approved
grass catcher in place. Never attempt to
operate the lawn mower with the rear

ENGINE
CARBURETOR
Your carburetor has a non-adjustable _ed
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.
IMPORTANT: Never tamper with the engine
governor, which is factory set for proper
engine speed. Overspeeding the engine
above the factory high speed setting can be
dangerous, if you think the engine-governed
high speed needs adjusting, contact your
nearest authorized service center, which has
proper equipment and experience to make
any necessary adjustments.
ENGINE SPEED
Your engine speed has been factoryset. 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 slow,
take your lawn mower to an authorized
service center for repair and adjustment.

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

LAWNMOWF_R

of time, clean it thoroughly, remove all dirt,
grease, leaves, etc. Store in a _e_,,, dry area,
• Clean entire lawn mower (See CLEANING" in the Maintenance section of this
manual).
• Lubricate as shown in the Maintenance
of this manual.

FUEL SYSTEM

ENGINE

IMPORTANT:
It is important to prevent
_luUmdeposits from forming in essential
el 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.
• Use fresh fuel next season.
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 10 minutes after adding
stabilizer to allow the stabilizer to reach
the carburetor.
Do not drain the gas tank
and carburetor
if using fuel stabilizer.

TROUBLESHOOTING

Drain oil (with engine warm) and replace
with clean engine oil, (See "ENGINE" in
the Maintenance section of this manual).
CYLINDER

• Do not store gasoline from one season
to another.
• Replace your gasoline can if your can
starts to rust. Rust and/or dirt in your
gasoline will cause problems.
• If possible, store your unit indoors and
cover it to give protection from dust and
dirt.
• Cover your unit with a suitable protective cover that does not retain moisture.
Do not use plastic, Plastic cannot
breathe which allows condensation
to
form and will cause your unit to rust.
IMPORTANT:

engine

and exhaust

areas are still warm.

_CAUTION:
Never store the lawn
mower with gasoline in the tank in_;ide a
building where fumes may reach an open
