SAFETY RULES
Safe Operation Practices for Walk-Behind Mowers
IMPORTANT: THIS CUTTING MACHINE IS CAPABLE OF AMPUTATING HANDS AND FEET AND THROWING OBJECTS. FAILURE
TO OBSERVE THE FOLLOWING SAFETY INSTRUCTIONS COULD RESULT IN SERIOUS INJURY OR DEATH.
DO NOT:
• Do not trim near drop-offs, ditches or embankments.
The operator could lose footing or balance.
• Do not trim excessively steep slopes.
• Do not mow on wet grass. Reduced footing could cause
slipping.
I. GENERAL OPERATION
•
•
•
•
•
•
•
•
•
•
•
•
•
•
•
•
•
•
Read, understand, and follow all instructions on the
machine and in the manual(s) before starting. Be thoroughly familiar with the controls and the proper use of
the machine before starting.
Do not put hands or feet near or under rotating parts.
Keep clear of the discharge opening at all times.
Only allow responsible individuals, who are familiar
with the instructions, to operate the machine.
Clear the area of objects such as rocks, toys, wire,
bones, sticks, etc., which could be picked up and thrown
by the blade.
Be sure the area is clear of other people before mowing. Stop machine if anyone enters the area.
Do not operate the mower when barefoot or wearing
open sandals. Always wear substantial foot wear.
Do not pull mower backwards unless absolutely necessary. Always look down and behind before and while
moving backwards.
Do not operate the mower without proper guards,
plates, grass catcher or other safety protective devices
in place.
See manufacturer’s instructions for proper operation
and installation of accessories. Only use accessories
approved by the manufacturer.
Stop the blade(s) when crossing gravel drives, walks,
or roads.
Stop the engine (motor) whenever you leave the equipment, before cleaning the mower or unclogging the
chute.
Shut the engine (motor) off and wait until the blade comes
to complete stop before removing grass catcher.
Mow only in daylight or good artificial light.
Do not operate the machine while under the influence
of alcohol or drugs.
Never operate machine in wet grass. Always be sure of
your footing: keep a firm hold on the handle and walk;
never run.
Disengage the self-propelled mechanism or drive clutch
on mowers so equipped before starting the engine (motor).
If the equipment should start to vibrate abnormally,
stop the engine (motor) and check immediately for the
cause. Vibration is generally a warning of trouble.
Always wear safety goggles or safety glasses with side
shields when operating mower.
III. CHILDREN
Tragic accidents can occur if the operator is not alert to
the presence of children. Children are often attracted to
the machine and the mowing activity. Never assume that
children will remain where you last saw them.
• Keep children out of the trimming area and under the
watchful care of another responsible adult.
• Be alert and turn machine off if children enter the
area.
• Before and while walking backwards, look behind and
down for small children.
• Never allow children to operate the machine.
• Use extra care when approaching blind corners, shrubs,
trees, or other objects that may obscure vision.
IV. SERVICE
•
•
•
•
•
•
•
II. SLOPE OPERATION
•
Slopes are a major factor related to slip and fall accidents
which can result in severe injury. All slopes require extra
caution. If you feel uneasy on a slope, do not mow it.
•
DO:
• Mow across the face of slopes: never up and down. Exercise extreme caution when changing direction on slopes.
• Remove obstacles such as rocks, tree limbs, etc.
• Watch for holes, ruts, or bumps. Tall grass can hide
obstacles.
•
•
2
Use extra care in handling gasoline and other fuels.
They are flammable and vapors are explosive.
- Use only an approved container.
- Never remove gas cap or add fuel with the
engine running.
Allow engine to cool before
refueling. Do not smoke.
- Never refuel the machine indoors.
- Never store the machine or fuel container inside
where there is an open flame, such as a water
heater.
Never run a machine inside a closed area.
Never make adjustments or repairs with the engine
(motor) running. Disconnect the spark plug wire, and
keep the wire away from the plug to prevent accidental
starting.
Keep nuts and bolts, especially blade attachement
bolts, tight and keep equipment in good condition.
Never tamper with safety devices. Check their proper
operation regularly.
Keep machine free of grass, leaves, or other debris
build-up. Clean oil or fuel spillage. Allow machine to
cool before storing.
Stop and inspect the equipment if you strike an object.
Repair, if necessary, before restarting.
Never attempt to make wheel height adjustments while
the engine (motor) is running.
Grass catcher components are subject to wear, damage, and deterioration, which could expose moving
parts or allow objects to be thrown. Frequently check
components and replace with manufacturer’s recommended parts, when necessary.
Mower blades are sharp and can cut. Wrap the blade(s)
or wear gloves, and use extra caution when servicing
them.
Do not change the engine governor setting or overspeed
the engine.
Look for this symbol to point out impor tant safety precautions. It means
CAUTION!!! BECOME ALERT!!! YOUR
SAFETY IS INVOLVED.
WARNING: Battery posts, terminals and
related accessories contain lead and
lead compounds, chemicals known to
the State of California to cause cancer
and birth defects or other reproductive
harm. Wash hands after handling.
CAUTION: Always disconnect spark plug
wire and place wire where it cannot contact
spark plug in order to prevent accidental
starting when setting up, transporting,
adjusting or making repairs.
CAUTION: Muffler and other engine
parts become extremely hot during
operation and remain hot after engine
has stopped. To avoid severe burns on
contact, stay away from these areas.
WARNING: Engine exhaust, some of
its constituents, and certain vehicle
components contain or emit chemicals known to the State of California

Fill fuel tank to bottom of tank filler neck. Do not overfill. 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.
OPERATION
MOWING TIPS
CAUTION: Wipe off any spilled oil or
fuel. Do not store, spill or use gasoline
near an open flame.
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. To
avoid engine problems, the fuel system
should be emptied before storage of
30 days or longer. Empty the gas tank,
start the engine and let it run until the
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 the fuel tank or permanent
damage may occur.

MULCHING MOWING TIPS
TO STOP ENGINE
•
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.
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.
IMPORTANT: FOR BEST PERFORMANCE, KEEP MOWER
HOUSING FREE OF BUILT-UP GRASS AND TRASH. SEE
“CLEANING”INTHEMAINTENANCESECTIONOFTHISMANUAL.
To stop engine, release operator presence control bar.
Wait until blade and all moving parts have stopped and
turn fuel valve to OFF position if you do not intend to
restart the engine soon.
•
TO START ENGINE (See Fig. 14)
NOTE: Due to protective coatings on the engine, a small
amount of smoke may be present during the initial use of
the product and should be considered normal.
1. Be sure fuel valve is in the ON position.
2. Move choke lever to ON ( ) position.
3. Hold operator presence control bar down to the handle
and pull starter handle quickly. Do not allow starter rope
to snap back.
NOTE: The choke lever automatically begins moving to
the OFF position when operator presence control bar is
held down to handle.
OFF
•
•
CHOKE LEVER
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 afternoon.
At this time the grass has dried, yet the newly cut area
will not be exposed to direct sunlight.
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. 15). 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 by
overlapping previously cut path and mow slowly.

FIG. 15
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 (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.

•
•
•
Clean the underside of your lawn mower by scraping
to remove build-up of grass and trash.
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.
CLEAN UNDER DRIVE COVER
Clean under drive cover at least twice a season. Scrape underside of cover with putty knife or similar tool to remove any
build-up of trash or grass on underside of drive cover.
SERVICE AND ADJUSTMENTS
CAUTION: TO AVOID SERIOUS INJURY, BEFORE PERFORMING ANY SERVICE OR ADJUSTMENTS:
1. Release control bar and stop engine.
2. Make sure the blade and all moving parts have completely stopped.
3. Disconnect the spark plug wire from the spark plug and place the wire where it cannot come
into contact with the spark plug.
LAWN MOWER
REAR DEFLECTOR
TO ADJUST CUTTING HEIGHT
The rear deflector, attached between the rear wheels of
your mower, is provided to minimize the possibility that
objects will be thrown out of the rear of the mower into
the operator's mowing position. If the deflector becomes
damaged, it should be replaced.
See “TO ADJUST CUTTING HEIGHT” in the Operation
section of this manual.

must be performed by an authorized engine manufacturer's
service outlet.
ENGINE SPEED
12. Connect spark plug wire to spark plug.
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 slow,
take your lawn mower to an authorized service center for
repair and adjustment.
TO ADJUST HANDLE (See Fig. 22)

operate properly due to suspected carburetor problems,
take your lawn mower to an authorized service center for
repair and/or adjustment.
IMPORTANT: NEVERTAMPER WITHTHE 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.
STORAGE
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.
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.
1. Clean entire lawn mower (See “CLEANING” in the
Maintenance section of this manual).
2. Lubricate as shown in the Maintenance section of this
manual.
3. Be sure that all nuts, bolts, screws, and pins are securely fastened. Inspect moving parts for damage,
breakage and wear. Replace if necessary.
4. Touch up all rusted or chipped paint surfaces; sand
lightly before painting.
15
STORAGE
HANDLE (See Figs. 23 and 24)
ENGINE
You can fold your lawn mower handle for storage.
1. Loosen the two (2) handle knobs on sides of the upper
handle and allow handle to fold down to the rear.
2. Remove the two (2) handle knobs and carriage bolts
on sides of the lower handle and pivot entire handle
assembly forward and allow it to rest on mower.
3. Reinstall knobs and carriage bolts to lower handle or
handle brackets for safe keeping.
• When setting up your handle from the storage position, you must manually lock the lower handle into the
mowing position.
FUEL SYSTEM
IMPORTANT: IT IS IMPORTANT TO PREVENT GUM DEPOSITS
FROM FORMING IN ESSENTIAL FUEL SYSTEM PARTS SUCH
AS CARBURETOR, FUEL FILTER, FUEL HOSE, OR TANK
DURING STORAGE. ALSO, 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.
•
Empty the fuel tank by starting the engine and letting
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 empty
the gas tank and carburetor if using fuel stabilizer.
IMPORTANT: WHEN FOLDING THE HANDLE FOR STORAGE
OR TRANSPORTATION, BE SURE TO FOLD THE HANDLE AS
SHOWN OR YOU MAY DAMAGE THE CONTROL CABLES.

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: NEVER COVER MOWER WHILE ENGINE AND
EXHAUST AREAS ARE STILL WARM.
CAUTION: Never store the lawn mower
with gasoline in the tank inside a building where fumes may reach an open
flame or spark. Allow the engine to cool
before storing in any enclosure.
