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.

I. GENERAL OPERATION

•Read, understand, and follow all

instructions on the machine and in the

manual(s) before starting. 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 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. 2

• 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 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.

I1.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.

II1. 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 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 acciden-

tal 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

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.

Open mulcher door

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 the 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 it to

read the dipstick.

3. Reinstall engine oil cap and tighten.

• 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

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.

AWARNING: 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. 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.

•1_CAUTION: Fill to bottom of gas tank

filler neck. Do not overfill. Wipe off any

spilled oil or fuel, Do not store, spill or

use gasoline near an open flame.

TO START ENGINE

NOTE: Due to protective coatings on the

engine, asmall amount of smoke may be

present during the initial use of the

product and should be considered

normal.

1. To start a cold engine, push primer

three (3) times before trying to start.

Use a firm push. This step is not

usually necessary when starting an

engine which has already run for a

few minutes.

2. Move throttle control lever to FAST

position.

3. Hold operator presence control bar

down to the handle and pull starter

handle quickly. Do not allow starter

rope to snap back.

TO STOP ENGINE

• To stop engine, release operator

presence control bar.

NOTE: In cooler weather it may be

necessary to repeat priming steps. In

warmer weather over priming may cause

flooding and engine will not start. If you

do flood engine, wait a few minutes

before attempting to start and do not

repeat priming steps.

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 filled with dirt and dust with

use and catchers will collect less grass. 9

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

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 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 mulching, 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 perpendicu-

lar 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

Adjustments 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.
