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 dis-

charge 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 bare-

foot 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 ap-

proved 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 mech-

anism 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. Vibra-

tion is generally a warning of trouble.

• Always wear safety goggles or safety

glasses with side shields when oper-

ating 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 cau-

tion. 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 ma-

chine and the mowing activity. Neveras-

sume 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

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

attachment bolts, tight and keep equip-

ment 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 set-

ting or overspeed the engine.

BEFORE STARTING ENGINE

ADD OIL

Your lawnmower is shipped without oil in

the engine. For type and grade of oil to

use, see "ENGINE" in the Maintenance

section of this manual.

CAUTION: DO NOT overfill engine with

oil, or it will smoke on startup.

1. Be sure lawnmower is level and area

around oil fill is clean.

2. Remove oil dipstick from oil fill spout.

Make sure that rim of spout is clean.

3. You receive a container of oil with the

unit. Slowly pour the entire container

down the oil fill spout into the engine.

4. Wait one minute to allow oil to settle. Oil

Use guage on oil fill cap/dipstick for

checking level. Insert dipstick into the cap

tube and rest the oil fill cap on the tube. 8

DO NOT thread the cap into the tube

when taking reading.

5. Always be sure to retighten oil dipstick

before starting engine.

• 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.

ADD GASOLINE

• 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. Pur-

chase fuel in quantities 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 flame.

CAUTION: Alcohol blended fuels

(called gasohol or using ethanol or metha-

nol) 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. Drain 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.

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 clip-

pings. It may also be necessary to re-

duce 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 cut-

ting conditions, the engine speed should

be set in the FAST position.

•Pores in cloth grass catchers can be-

come 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.

MULCHING MOWING TIPS

IMPORTANT: For best performance, keep

mower housing free of built-up grass and

trash. See "CLEANING" in the Mainte-

nance 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 recut-

ting 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 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 overloading the engine and leaving

clumps of mulched grass. For extremely

heavy grass, reduce your width of cut

by overlapping previously cut path and

mow slowly.

MAX 1/3

• 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 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.

GENERAL RECOMMENDATIONS

The warranty on this lawn mower does not

cover items that have been subjected to

operator abuse or negligence. To receive

full value from the warranty, operator

must maintain mower as instructed in this

manual. Some adjustments will need to

be made periodically to properly maintain

your unit.

All adjustments in the Service and Adjust-

ments section of this manual should be

checked at least once each season.

•Once a year, replace the spark plug,

clean or replace air filter element and

check blade for wear. A new spark plug

and clean/new air filter element assure

proper air-fuel mixture and help your

engine run better and last longer.

• Follow the maintenance schedule in this

manual.

LUBRICATION CHART

Mulcher

door hinge

Rear door

hinge

(_ Handle bracket mounting pins

BEFORE EACH USE

1. Check engine oil level.

2. Check for loose fasteners.

LUBRICATION

Keep unit well lubricated (See "LUBRI-

CATION CHART").

Spray lubricant

See "ENGINE" in Maintenance section.

IMPORTANT: Do not oil or grease

plastic wheel bearings. Viscous lubri-

cants will attract dust and dirt that will

shorten the life of the self-lubricating

bearings. If you feel they must be

lubricated, use only a dry, powdered

graphite type lubricant sparingly.
