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.

SAFETY RULES

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.

• Never direct discharged material toward anyone.

Avoid discharging material against a wall or obstruc-

tion. Material may richochet back toward the operator.

Stop the blade when crossing gravel surfaces.

• 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. Exer-

cise 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.

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 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.

IV. SAFE HANDLING OF GASOLINE

Use extreme care in handling gasoline. Gasoline is ex-

tremely ﬂ ammable and the vapors are explosive.

• Extinguish all cigarettes, cigars, pipes and other sources

of ignition.

• Use only an approved container.

• Never remove gas cap or add fuel with the engine run-

ning. Allow engine to cool before refueling.

3

• Never refuel the machine indoors.

• Never store the machine or fuel container where there

is an open ﬂ ame, spark or pilot light such as a water

heater or on other appliances.

• Never ﬁ ll containers inside a vehicle, on a truck or trailer

bed with a plastic liner. Always place containers on

the ground away from your vehicle before ﬁ lling.

• Remove gas-powered equipment from the truck or trailer

and refuel it on the ground. If this is not possible, then

refuel such equipment with a portable container, rather

than from a gasoline dispenser nozzle.

• Keep the nozzle in contact with the rim of the fuel tank

or container opening at all times until fueling is complete.

Do not use a nozzle lock-open device.

• If fuel is spilled on clothing, change clothing immedi-

ately.

• Never overﬁ ll fuel tank. Replace gas cap and tighten

securely.

V. GENERAL SERVICE

• Never run a machine inside a closed area.

• Never make adjustments or repairs with the engine

(motor) running. Disconnect spark plug wire, and keep

wire away from 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 blade is sharp and can cut. Wrap the blade or

wear gloves, and use extra caution when servicing it.

• Do not change the engine governor setting or overspeed

the engine.

• Maintain or replace safety and instruction labels, as

necessary.

WARNING: This lawn mower is equipped with an internal com bus tion engine and should not be used on or near any

un im proved forest-covered, brush-covered or grass-cov ered land unless the engine’s exhaust system is equipped with

a spark arrester meeting applicable local or state laws (if any). If a spark arrester is used, it should be maintained in

effective working order by the operator.

In the state of California the above is required by law (Section 4442 of the California Public Resources Code). Other

states may have similar laws. Federal laws apply on federal lands. A spark arrester for the mufﬂ er is available

OPERATION

ADD GASOLINE (See Fig. 13)

• Fill fuel tank to bottom of tank ﬁ ller neck. Do not over-

ﬁ 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 at-

tract moisture which leads to separation

and for ma tion of acids during storage.

Acidic gas can damage the fuel sys-

tem 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.

TO STOP ENGINE

• To stop engine, move throttle control lever to STOP

position. Wait until blade and all moving parts have

stopped and turn fuel valve to OFF position if you do

not intend to re start 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 po si tion.

2. To start a cold engine, move handle mounted throttle/

choke con trol le ver to CHOKE position.

3. Pull starter handle quickly. Do not allow starter rope to

snap back.

4. Slowly move throttle control lever to FAST position

after engine starts.

MOWING TIPS

CAUTION: Do not use de-thatcher

blade attachments. Such attachments

are hazardous, will damage your mower

and could void your warranty.

• 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.

MULCHING MOWING TIPS

IMPORTANT: FOR BEST PERFORMANCE, KEEP MOWER

HOUSING FREE OF BUILT-UP GRASS AND TRASH. SEE

“CLEANING” IN MAINTENANCE SECTION OF THIS MANUAL.

• The special mulching blade will recut the grass clip-

pings 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 biode-

grade 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 over-

grown 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.

• 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 ﬁ rst cut path.

• Change your cutting pattern from week to week. Mow

north to south one week then east to west the next week.

This will help prevent matting and graining of the lawn.

LAWN MOWER

Always observe safety rules when performing 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 you mow to be sure they

move freely. The wheels not turning freely means trash,

grass cuttings, etc., may be inside the drive wheel and dust

cover area and must be cleaned out to free drive wheels.

If necessary to clean drive wheels, check both rear wheels.

BLADE CARE

For best results, mower blade must be kept sharp. Re place

a bent or dam aged blade.

CAUTION: Use only a replacement blade

approved by the manufacturer of your

mower. Using a blade not approved

by the manufacturer of your mower is

hazardous, could damage your mower

and void your warranty.

TO REMOVE BLADE (See Fig. 16)

1. Disconnect spark plug wire from spark plug and place

wire where it cannot come in contact with 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 bolts.

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

with heavy cloth.

4. Remove blade bolts by turning counter-clockwise.

TO REPLACE BLADE (See Fig. 16)

1. Position the blade. Be sure trailing edge of blade (op-

posite sharp edge) is up toward the engine and install

the blade bolts.

2. Use block of wood between blade and lawn mower hous-

ing and tighten the blade bolts, turning clockwise.

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

IMPORTANT: BLADE BOLTS ARE HEAT TREATED. IF BOLTS

NEED REPLACING, REPLACE ONLY WITH APPROVED BOLTS

SHOWN IN THE REPAIR PARTS SECTION OF THIS MANUAL.

MAINTENANCE

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 grind-

ing 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 replace-

ment catcher shown in the Repair Parts section of this

manual. Give the mower model number when order-

ing.

GEAR CASE

• To keep your drive system working properly, the gear

case and area around the drive should be kept clean

and free of trash build-up. Clean under the drive cover

twice a season.

• The gear case is ﬁ lled with lubricant to the proper

level at the factory. The only time the lubricant needs

attention is if service has been performed on the gear

case.

• If lubricant is required, use only Texaco Starplex Pre-

mi um 1 Grease, Part No. 750369. Do not substitute.

ENGINE

LUBRICATION

Use only high quality detergent oil rated with API service

classiﬁ cation SG–SL. 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.

MAINTENANCE

TO CHANGE ENGINE OIL (See Figs. 17 & 18)

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 plug.

2. Remove oil ﬁ ll cap/dipstick; lay aside on a clean sur-

face.

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

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 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 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 un-

derside of cover with putty knife or similar tool to remove any

build-up of trash or grass on underside of drive cover.

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.

7. Continue adding small amounts of oil and rechecking

the dipstick until it reads full. DO NOT overﬁ ll, or engine

will smoke on startup.

8. Always be sure to retighten oil ﬁ ll cap/dipstick before

starting engine.

9. Reconnect spark plug wire to spark plug.

13

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 spark plug wire from spark

plug and place where it cannot come in

contact with plug.

LAWN MOWER

TO ADJUST CUTTING HEIGHT

See “TO ADJUST CUTTING HEIGHT” in the Operation

section of this manual.

REAR DEFLECTOR

The rear deﬂ ector, 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 deﬂ ector becomes

damaged, it should be replaced.

TO REMOVE DRIVE BELT

If your mower does not operate properly due to suspected

drive belt problems, take your mower to a qualiﬁ ed service

center for repair and/or ad just ment.

TO ADJUST HANDLE (See Fig. 19)

The handle on your lawn mower has three (3) height posi-

tions - adjust to height that suits you.

• Squeeze the bottom ends of lower handle towards each

other until the pin in handle can be inserted into one

of the three height adjustment holes.

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.

STORAGE

ENGINE

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. 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 mini-

mizing 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 en-

gine 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.
