CAUTIONH! BECOME ALERTN!

YOUR SAFETY IS INVOLVED.

_i, WARNING: In order to prevent ac-

cidental starting when setting up, trans- porting, adjusting or making repairs, always disconnect spark plug wire and place wire where it cannot come in contact

with plug.

_WARNING: Engine exhaust, some of its

constituents, and certain vehicle components contain or emit chemicals known to the State

of California to cause cancer and birth defects or other reproductive harm.

AWARNING: Battery posts, terminals and

related accessories contain lead and lead compounds, chemicals known to the State

of California to cause cancer and birth defects or other reproductive harm. Wash

hands after handling.

A CAUTION: Muffler and other engine

parts become extremely hot during

operation and remain hot after engine has stopped. To avoid severe burns on contact,

stay away from these areas.

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 oper- ate the machine.

• Clear the area of objects such as rocks,

toys, wire, bones, sticks, etc., which could be picked up and thrown by 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.

• Never direct discharged material toward

anyone. Avoid discharging material against a wall or obstruction. Material may richochet back toward the opera- tor. 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 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; walk, never run.

• Disengage the self-propelled mech-

anism or drive clutch on mowers so equipped before starting the engine.

• 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 operating

mower.

II. SLOPE OPERATION

Slopes are a major factor related to slip & fall accidents which can result in severe in-

jury. 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 foot-

ing 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 ma-

chine.

• 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 extremely flammable 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 running. Allow engine to cool

before refueling.

• Never refuel the machine indoors.

• Never store the machine or fuel contain- er where there is an open flame, spark

or pilot light such as a water heater or on other appliances.

• Neverfill containersinsidea vehicle,on atruckortrailerbedwitha plasticliner.

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. A CAUTION: DO NOT overfill engine with oil, or it will smoke heavily from the muffler

on startup.

1. Be sure lawnmower is level.

2. Remove oil dipstick from oil fill spout.

3. You receive a container of oil with the unit. Slowly pour the entire container

down the oil fill spout into the engine.

Engine

oil cap

Gasoline filler cap

Primer

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.

A_, 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 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. 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 Instructions for additional information. Never use engine

or carburetor cleaner products in the fuel tank

or permanent damage may occur.

TO STOP ENGINE

• Tostopengine,releaseoperatorpres- encecontrolbar.

TO START ENGINE

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. 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. Hold operator presence control bar down to the handle and pull starter handle quickly. Do not allow starter rope to snap back.

NOTE: In cooler weather it may be neces- sary 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 attempt-

ing to start and do not repeat priming steps.

MOWING TIPS A CAUTION: Do not use de-thatcher

blade attachments on your mower. 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 cut- ting 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. 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 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, 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. 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.

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 sec- ond cut, mow across (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 unit as instructed in this manual.

Some adjustments will need to be made

periodically to properly maintain your unit.

At least once a season, check to see if you should make any of the adjustments described in the Service and Adjustments

section of this manual.

• At least 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.

BEFORE EACH USE

• Check engine oil level.

• Check for loose fasteners.

LU BRICATION Keep unit well lubricated

TO SHARPEN BLADE NOTE: We do not recommend sharp-

ening the blade - but if you do, be sure the blade is balanced. An unbalanced

blade will cause eventual damage to lawn mower or engine.

• The blade can be sharpened with a file or on a grinding 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 exposed. 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 dam-

age or deterioration. Through normal use it will wear. If catcher needs replac- ing, replace only with approved replace- ment catcher shown in the Repair Parts

section of this manual. Give the lawn

mower model number when ordering.

ENGINE

LU BRICATION

Use only high quality detergent oil rated

with API service classification SG-SL.

Select the oil's SAE viscosity grade according to your expected operating

temperature.

TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE

NOTE: Although multi-viscosity oils (5W30, 10W30 etc.) improve starting in

cold weather, these multi-viscosity oils will result in increased oil consumption when

used above 32°F. Check your engine oil level more frequently to avoid possible

engine damage from running low on oil.

Check the crankcase oil level before

starting the engine and after each five (5) hours of continuous use. Tighten oil plug securely each time you check the oil level.
