SAFETY RULES

Safe Operation Practices for Walk-Behind Mowers

IMPORTANT: THIS CUTTING MACHINE IS CAPABLE OF AMPUTATING HANDS AND FEET AND THROW ING OBJECTS. FAILURE

TO OBSERVE THE FOLLOWING SAFETY INSTRUCTIONS COULD RESULT IN SERIOUS INJURY OR DEATH.

I. GENERAL OPERATION

• Read, understand, and follow all instructions on the
machine and in the manual(s) before starting. Be thor­ ough ly 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 mow­ ing. 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 nec­ es sary. 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 equip­ ment, 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 catch er.

• Mow only in daylight or good artifi cial light.

• Do not operate the machine while under the infl uence
of alcohol or drugs.

• Never operate machine in wet grass. Always be sure of
your footing: keep a fi rm 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.

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.

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.

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.
children will remain where you last saw them.

• Keep children out of the trimming area and under the
watchful care of another re spon si ble 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.

Never

assume that

IV. SERVICE

• Use extra care in handling gasoline and other fuels.
They are fl ammable 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 fl ame, 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, dam­ age, and deterioration, which could expose moving
parts or allow objects to be thrown. Frequently check
com po nents and replace with manufacturer’s rec om ­mend ed 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

HOW TO USE YOUR LAWN MOWER

ENGINE SPEED

The engine speed was set at the factory for optimum per­formance. Speed is not adjustable.

ENGINE ZONE CONTROL

CAUTION: Federal regulations require
an engine control to be installed on this
lawn mower in order to minimize the risk
of blade contact injury. Do not un der
any cir cum stanc es attempt to defeat
the function of the operator control.
The blade turns when the engine is
running.

• Your lawn mower is equipped with an operator presence
control bar which requires the operator to be positioned
behind the lawn mower handle to start and operate the
lawn mower.

DRIVE CONTROL (See Fig. 5)

• Self-propelling is controlled by hold ing the operator
presence control bar down to the handle and pulling
the drive control lever rearward to the handle. The
farther toward the handle the lever is pulled, the faster
the unit will travel.

• Forward motion will stop when either the operator pres­ence control bar or drive control lever are released. To
stop forward motion without stop ping engine, re lease
the drive control lever only. Hold op er a tor presence
control bar down against handle to con tin ue mowing
without self-propelling.

NOTE: If after releasing the drive control the mower will
not roll backwards, push the mower forward slightly to
disengage drive wheels.

OPERATOR PRESENCE CONTROL BAR

OPERATION

BEFORE STARTING ENGINE

ADD OIL (See Figs. 12 and 13)

Your lawnmower is shipped without oil in the engine. For type
and grade of oil to use, see “EN GINE” in the Maintenance
section of this manual.

CAUTION: DO NOT overfi ll engine with
oil, or it will smoke on startup.

1. Be sure lawnmower is level and area around oil fi ll is clean.

2. Remove oil dipstick from oil fi ll spout. Make sure that
rim of spout is clean.

3. Engine holds 18.5 ounces of oil. For type and grade
of oil to use, see “ENGINE” in the Maintenance section
of this manual.

4. Pour oil slowly. Do not overfi ll. Wait one minute to al­low oil to settle. Use guage on oil fi ll cap/dipstick for
checking level. Insert dipstick into the tube and rest
the oil fi ll cap on the tube. DO NOT thread the cap into
the tube when taking reading.

5. Always be sure to tighten dipstick before star ting engine.

IMPORTANT:

• Check oil level before each use. Add oil if needed. Fill
to full line on dipstick.

• Change the oil after every 25 hours of operation or each
season. You may need to change the oil more often
under dusty, dirty conditions. See “TO CHANGE EN­GINE OIL” in the Maintenance section of this manual.

ADD GASOLINE (See Fig. 13)

• Fill fuel tank to bottom of tank fi ller neck. Do not over­fi ll. Use fresh, clean, regular unleaded gasoline with
a minimum of 87 octane. Do not mix oil with gasoline.
Purchase fuel in quan ti ties that can be used within 30
days to assure fuel freshness.

CAUTION: Wipe off any spilled oil or
fuel. Do not store, spill or use gasoline
near an open fl ame.

Alcohol blended fuels (called gasohol
or using ethanol or methanol) can at­tract moisture which leads to separation
and for ma tion 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. 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
In struc tions for additional information.
Never use engine or carburetor cleaner
products in the fuel tank or permanent
damage may occur.

MULCHING MOWING TIPS

IMPORTANT: FOR BEST PERFORMANCE, KEEP MOWER

HOUSING FREE OF BUILT-UP GRASS AND TRASH. SEE
“CLEANING” IN THE 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 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.

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.

• 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 fi lled 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 fl ow
and extend engine life.

MAX 1/3

FIG. 15

• Cer tain 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 fi rst 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.

LAWN MOWER

Always observe safety rules when performing any main­ te nance.

TIRES

• Keep tires free of gasoline, oil, or insect control chem­ i cals which can harm rubber.

• Avoid stumps, stones, deep ruts, sharp objects and
other hazards that may cause tire damage.

DRIVE WHEELS

Check rear drive wheels each time be fore you mow to be
sure they move freely.

The wheels not turning freely means trash, grass cuttings,
etc. are in the drive wheel area and must be cleaned to
free drive wheels.

If necessary to clean the drive wheels, be sure to clean
both rear wheels.

BLADE CARE

For best results, mower blade must be kept sharp. Re place
bent or dam aged blades.

TO REMOVE BLADE (See Fig. 16)

1. Disconnect spark plug wire from spark plug and place
wire where it cannot come in contact with spark plug.

2. Turn lawn mower on its side. Make sure air fi lter and
carburetor are up.

3. Use a wood block between blade and mower hous ing
to prevent blade from turning when re mov ing blade bolt.

NOTE: Protect your hands with gloves and/or wrap blade
with heavy cloth.

4. Remove blade bolt by turning counter-clockwise.

5. Remove blade and attaching hardware (bolt, lock wash er
and hardened wash er).

TO REPLACE BLADE (See Fig. 16)

1. Position blade on the blade adapter aligning the two
(2) holes in the blade with the raised lugs on the
adapter.

2. Be sure the trailing edge of blade (opposite sharp edge)
is up toward the engine.

3. Install the blade bolt with the lock washer and hard ened
washer into blade adapter and crank shaft.

4. Use block of wood between blade and lawn mower
housing and tighten the blade bolt, turning clock wise.

• The recommended tightening torque is 35-40 ft. lbs.

IMPORTANT: BLADE BOLT IS HEAT TREATED. IF BOLT NEEDS
REPLACING, REPLACE ONLY WITH APPROVED BOLT SHOWN
IN THE REPAIR PARTS SECTION OF THIS MANUAL.

TO SHARPEN BLADE
NOTE: We do not recommend sharp en ing blade - but if

you do, be sure the blade is balanced.

Care should be taken to keep the blade balanced. An
un bal anced blade will cause eventual damage to lawn
mower or engine.

• The blade can be sharp ened with a fi le 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 ex posed.
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.

GRASS CATCHER

• The grass catcher may be hosed with water, but must
be dry when used.

• Check your grass catcher often for damage or de te ­ri o ra tion. Through normal use it will wear. If catcher
needs replacing, replace only with ap proved replace­ment catcher shown in the Repair Parts section of this
manual. Give the lawn mower model number when
ordering.

ENGINE

LUBRICATION

Use only high quality detergent oil rated with API service
classifi cation SF-SJ. Select the oil's SAE viscosity grade
according to your expected operating temperature.

NOTE: Multi-viscosity oils (5W30, 10W30 etc.) improve
starting in cold weather, and you should check your engine
oil level frequently to avoid possible engine damage from
running low on oil.

Change the oil after every 25 hours of operation 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 fi ve (5) hours of continuous use. Tighten oil
plug securely each time you check the oil level.

13

MAINTENANCE

TO CHANGE ENGINE OIL (See Fig. 17)

NOTE: Before tipping lawn mower to drain oil, empty fuel

tank by running engine until fuel tank is empty.

1. Disconnect spark plug wire from spark plug and place
wire where it cannot come in contact with spark plug.

2. Remove engine oil cap; lay aside on a clean surface.

3. Tip lawn mower on its side as shown and drain oil into
a suitable container. Rock lawn mower back and forth
to remove any oil trapped inside of engine.

4. Wipe off any spilled oil from lawn mower or side of
engine.

5. Slowly pour oil down the oil fi ll spout, stopping every
few ounces to check the oil level with the dipstick.

6. Stop adding oil when you reach the FULL mark on the
dipstick. Wait a minute to allow oil to settle.

7. Continue adding small amounts of oil, rechecking the
dipstick until oil level settles at FULL. DO NOT over­fi ll, or engine will smoke heavily from the muffl er on
startup.

8. Always be sure to retighten oil dipstick before starting
engine.

9. Re con nect spark plug wire to spark plug.

AIR FILTER

Your engine will not run properly and may be damaged
by using a dirty air fi lter. Replace the air fi lter every 100
hours of operation or every season, whichever occurs fi rst.
Ser vice air cleaner more often under dusty conditions. See
the main te nance section of your engine manual.

MUFFLER

Inspect and replace corroded muffl er as it could create a
fi re hazard and/or damage.

SPARK PLUG

Replace spark plug at the beginning of each mowing season
or after every 100 hours of operation, whichever occurs
fi rst. Spark plug type and gap setting are shown in the
“PROD UCT SPEC I FI CA TIONS” section of this manual.

CLEANING

IMPORTANT: FOR BEST PERFORMANCE, KEEP MOWER

HOUSING FREE OF BUILT-UP GRASS AND TRASH. CLEAN
THE UNDERSIDE OF YOUR MOWER AFTER EACH USE.

CAUTION: Disconnect spark plug wire
from spark plug and place wire where it
cannot come in contact with spark plug.

• 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 fi nished 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, muffl er, air
fi lter 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.

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,

on the left side of the handle. This bracket prevents the
upper handle from folding forward, which helps protect
control cable(s) from damage.

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
as sem bly 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 lower handle into mowing

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, 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.

• Empty the fuel tank by starting the engine and letting
it run until the fuel lines and car bu re tor 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 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
allow the stabilizer to reach the carburetor. Do not empty
the gas tank and carburetor if using fuel stabilizer.

ENGINE OIL

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

CYLINDER

1. Remove spark plug.

2. Pour one ounce (29 ml) of oil through spark plug hole
into cylinder.

3. Pull starter handle slowly a few times to distribute oil.

4. Replace with new spark plug.

OTHER

• 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 build­ ing where fumes may reach an open
fl ame or spark. Allow the engine to cool
before storing in any enclosure.
