instructions on the machine and in the

manual(s) before starling. Be thor-

oughly familiar with the controls and the

proper use of'the machine before

starting.

• Do not put hands or feet near or under

rotating pads. 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.

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 eccessories

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

2before 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 mecha-

nism 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 rooks, 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 batance.

•Do nottrim 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

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 aclosed

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

equipment in good condition.

•Never tamper with safety devices.

Check their proper operation regularly.

•Keep machine free of grass, leaves, or

BEFORE STARTING ENGINE

ADD OIL

Your lawnmower is shipped without oil in

the engine. Engine holds 20 oz. of oil.

For type and grade of oil to use, see

ENGINE in Maintenance section of this

manual.

1. Be sure lawnmower is level and area

around oil fill is clean.

2. Remove engine oil cap and fill to the

full line on the dipstick. Pour oil slowly.

Do not over fill.

NOTE: Allow oil to settle down into engine

for accurate reading. To read proper level,

tighten engine oil cap, then remove itto

read the dipstick.

• 3. Reinstall engine oil cap and tighten.

•Check oil level before each use. Add

oil if needed. Fillto 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

NOTE: Before filling fuel tank, remove

and discard the debris plug that is inside

the tank.

•Fill fuel tank. Use fresh, clean, regular

unleaded gasoline with a minimum of

87 octane, Do not mix oil with gaso-

line. Purchase fuel in quantities that

can be used within 30 days to assure

fuel freshness.

MOWINGTiPS

• 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 ovedoading 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 ovedapping 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.

MULCHING MOWING TIPS

IMPORTANT: For best performance,

keep mower housing free of built-up

grass and trash. Clean UNDERSIDE OF

MOWER HOUSING after each use. See

"Cleaning" in MAINTENANCE section of

this manual.

• The special mulching blade will recur

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 biodegrede 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 eady

afternoon. At this time the grass has

dded 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 ovedoading the engine and

leaving clumps of mulched grass. For

extremely heavy mulching, reduce your

width of cut, mow slowly and raise

the rear of the lawn mower one wheel

adjuster setting higher than the front.

• 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 perpendicu-

lar to the firstcut 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.
