HOW TO USE YOUR LAWN MOWER
ENGINE SPEED CONTROL
The engine speed was set at the factory
for optimum performance. Speed is not
adjustable.
ENGINE ZONE CONTROL
ACAUTION:
Federal regulationsrequire an
engine controlto be installedon this lawn
mower in order to minimize the riskof blade
contact injury. Do not under any drcumstances
attempt to defeat the function of the operator
control. The blade fums when the engine is
running.
• Your lawn mower is equipped with an
operator presence controlbar which
requires the operator to be positioned
behind the lawn mower handle to start and
operate the lawn mower.

BEFORE STARTING ENGINE OIL
Your lawn mower is shipped without oil inthe
engine.
• Be sure mower is level and area around oil

• Remove engine oil cap and fillto the full line
on the dipstick.
• Use 20 ozs. of oil. For type and grada of oil
to use, see "ENGINE" in Maintenance
section of this manual.

• To read proper level, tighten engine oilcap
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 often under dusty,
dirtyconditions.
GAS
• Fill fuel tank. Use fresh, clean, 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
freshness.
WARNING: Experience indicates that alcohol
blended fuels (called gasuhoi or using ethanol
or methanol) can attract moisture which leads
to separalion 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
emp0ed before storage of 30 days or longer.
Drain the fuel tank, start the engine and let it
run unltl fuel lines and carburetor are empty.
Use fresh fuel next season. See Storage

TO START ENGINE

MULCHING MOWING TIPS

• 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.
• 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
attempting to start and do not repeat
priming steps.
MOWING
TIPS

IMPORTANT: For best performance, keep
mower housing free of built-up grass and
trash. See "Cleaning" in MAINTENANCE
section of this manual.

• 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.
• 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.
• For side discharge lawn mowers, cutting
in a counter-clockwise
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 clippings off of walkways, flower
beds, etc., make the first cuts in a
clockwise direction.
• 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 usirig.
• Keep top of engine around starter clear
and clean of grass clippings and chaff.
This will help engine air flow and extend
engine life.

• The special mulching blade will recut the
grass clippingsmany times and reduce
them in size so that as they fall onto the
lawn they will dLsperse intothe grass and
not be noticed. Also, the mulched grass will
biodegrade quickly to provide nutrientsfor
the lawn. Always mulch with your highest
engine (blade) speed as this v_l provide the
best recutting action of the blades.
• Avoid cutting your lawn when it is wet. Wet
grass tends to form dumps and interferes
with the mulching action. The best time to
mow your lawn is the early aftemoon. At
thistime 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 willbe 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 by overlapping
previously cut path and mow slowly.
• 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 flint cut path.
• Change your cutting pattern from weekto
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.

TO SHARPEN

BLADE

NOTE: We do not recommend sharpening
blade - but if you do, be sure the blade is

Care should be taken to keep the blade
balanced. An unbalanced blade will cause
eventual damage to lawn mower or

• The blade can be sharpened with a file
or on a grinding wheel. Do not attempt
to sharpen while on the mower.
• To check blade balance, drive a nail into
a beam or wall. Leave about one inch of
the straight nail exposed. Place center
hole of blade over the head of the nail.
If blade is balanced, it should remain in
a horizontal position. If either end of the
blade moves downward, sharpen the
heavy end until the blade is balanced.

10W30 etc.) improve startingin cold weather,
these multi-viscosityoils 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 every 25 hours of
operation orat least once a year ifthe 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

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

are securaly fastened. Inspect moving
parts for damage, breakage and wear.
Replace if necessary.

surfaces; sand lightlybefore painting.

FUEL SYSTEM
IMPORTANT: It is important to prevent gum
deposits from forming in essential fuel system
parts such as carburetor, fuel filter, fuel hos e,
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 untilthe 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 allowthe stabilizer to
reach the carburetor. Do not drain the gas
tank and carburetor if using fuel stabilizer.
