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

•Road, 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 waming of

trouble.

•Always wear safety goggles or safely

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.

II1. CHILDREN

Tragic accidents can occur if the operator

is not alert to the presence ofchildren.

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

comers, shrubs, trees, or other objects

that may obscure vision.

IV. SERVICE

ENGINE ZONE CONTROL

_CAUl"ION: Federal regulations require

an engine control to be installed on this

lawn mower in order to minimize the dsk

of blade contact injury. Do not under any

circumstances 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.

TO ADJUST CUTFING HEIGHT

Raise wheels for low cut and lower

wheels for high cut, adjust cutting height

to suit your requirements. Medium

position is best for most lawns.

ADD GASOLINE

NOTE: Before filling fuel tank, remove

and discard the debris plug that is inside

the tank.

• Fillfuel 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.

_WARNING: 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.

ACAUTION: 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 protoctive 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. 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 _r_a_ back.

MUWINU TiPS

• Under cedain 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.

• When using a rear discharge lawn

mower in moist, heavy grass, clumps of

cut grass may not enter the grass

catcher. Reduce ground speed

(pushing speed) and/or run the lawn

mower over the area a second time.

•If a trail of clippings is left on the dght

side of a rear discharge mower, mow in

a clockwise direction with a small

ovedap to collect the clippings on the

next pass.

•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 end

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 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 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 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 end 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 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

ROtcover 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

pedodically 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

assures proper air-fuel mixture and

helps your engine run better and last

longer.

•Follow the maintenance schedule in

this manual.

BEFORE EACH USE

1. Check engine oil level.

2. Check for loose fasteners.

LUBRICATION

Keep unit well lubricated (See "LUBRI-

CATION CHART").

LUBRICATION CHART

Wheel Adjuster

(_ Rear door hinge

_) Handle bracket

mounting pin

_) Refer to maintenance "Engine" section,

(_ Spray lubricant

IMPORTANT: Do not oil or grease

plastic wheel bearings, viscous lubd-

cants will attract dust and dirtthat 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.
