important safety precautions. It means CAUTION!!! BECOME ALERT!!!

YOUR SAFETY IS INVOLVED. _-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 into

contact with the spark plug. AWARNING: Engine exhaust, some of its

constituents, and certain vehicle compo-

nents contain or emit chemicals known

to the State of California to cause cancer and bi_!, ,!efects or other reproductive

harm.

_WARNING: 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.

_i, 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 the

blade.

• Be sure the area is clear of other people before mowing. Stop machine ifanyone

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 operating

mower. 3

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 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.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 runa 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 spill- age. 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 adjust- ments while the engine (motor) is running.

HOWTO USEYOUR LAWN MOWER

ENGINE SPEED

The engine speed was set at the factory for optimum performance. It is not adjustable.

ENGINE ZONE CONTROL

A, CAUTION: Federal regulations require

an engine control to be installed on this lawn mower in order to minimize the

risk 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.

DRIVE CONTROL

• Self-propelling is controlled by hold-

ing the operator presence control bar down to the handle and pulling the drive

control lever rearward to the handle. The farther toward the handle the lever

is pulled, the faster the unit will travel.

• Forward motion will stop when either the operator presence control bar or drive

control lever are released. To stop forward motion without stopping engine, release the drive control lever only. Hold operator presence control bar down against handle

tocontinue mowing without self-propelling.

NOTE: Ifafter releasing the drive control the mowerwill not rollbackwards, push the mow-

erforward slightly to disengage drive wheels.

DRIVE CONTROL ADJUSTMENT

Over time, the drive control system may be- come "loose", resulting in decreased speed.

There isa button onthe underside ofthe drive control housing to increase tension on the

drive cable. Proceed as follows:

1. Turn unit off and disconnect spark plug wire from spark plug.

2. Pull out button on underside of drive control, then push button back in.

3. Operate mower to test drive speed.

If conditi_._ _,"_omes worse after the

above ste_ ,yard speed has become slower), yo,_,_,ystem was not"loose". Re-

pealing the above steps will returnyour unittotheproperadjustmentand speed.

TO CONVERT MOWER

Your lawn mower was shipped ready to be

used as a mulcher. To convert to bagging:

• Open rear door and remove mulcher

plug. Store mulcher plug in a safe place.

• You can now install grass catcher or

optional clipping deflector.

• To convert to mulching or discharging

operation, install mulcher plug into rear

A0discharge opening of mower.

CAUTION" Do not run your lawn mower

without mulcher plug, clipping deflector or approved grass catcher in place. Never at- tempt to operate the lawn mower with the

rear door removed or propped open.

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. NOTE: Initial oil fill requires only 18 oz. due to residual oil in engine from the

manufacturers 100% quality testing. When changing oil you may need 20 oz.

4. Insert and tighten dipstick. IMPORTANT:

• Check oillevel 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. See "TO CHANGE ENGINE OI1" in the Mainte-

nance section of this manual.

ADD GASOLINE

• Fill fuel tank to bottom of tank filler neck

Do not overfill. Use fresh, clean, regula unleaded gasoline with a minimum of 8; octane. Do not mix oil with gasoline. Pur. chase fuel in quantities that can be use(

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. A 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. 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 inthe fuel

tank or permanent damage may occur.

TO STOP ENGINE

• To stop engine, release operatorpres- ence controlbar.

TO START ENGINE

NOTE: Due to protectivecoatingson the engine, a small amount of smoke maybe

present duringthe initialuse ofthe prod- uct and should be considerednormal.

1. To start a cold engine, push primer three (3) times beforetryingtostart.

Use a firm push.This step is not usuallynecessary when starting an engine whichhas already runfor a few

minutes.

2. Hold operatorpresence controlbar downto the handle and pullstarter

NOTE: Incoolerweatheritmaybenecessary to repeatprimingsteps. In warmerweather

overprimingmaycauseflooding andengine will not start. If you do flood engine, wait a

few minutesbeforeattemptingto start and do notrepeat primingsteps.

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 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.

• 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 right

side of a rear discharge mower, mow in a clockwise direction with a small overlap

to collect the clippings on the next pass.

• 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 starterclear

and clean ofgrass clippingsand 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 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 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..

must be lubricated, use only a dry,powdered graphite type lubricant sparingly.

LAWN MOWER

Alwaysobservesafetyruleswhen per-

forming any maintenance.

TIRES

• Keep tires free of gasoline, oil, or insect

control chemicals which can harm rub- ber.

• Avoid stumps, stones, deep ruts, sharp

objects and other hazards that may cause tire damage.

DRIVE WHEELS Check rear drive wheels each time you

mow to be sure they move freely. The wheels not turning freely means trash,

grass cuttings, etc., may be inside the drive wheel and dust cover area and must

be cleaned out to free drive wheels.

If necessary to clean the drive wheels,

check both rear wheels. BLADE CARE

For best results, mower blade must be

kept sharp. Replace a bent or damaged blade.

TO REMOVE BLADE

1. Disconnect spark plug wire from spark plug and place wire where it cannot

come in contact with plug.

2. Turn lawn mower on its side. Make sure air filter and carburetor are up.

3. Use a wood block between blade and mower housing to prevent blade from

turning when removing blade bolt.

NOTE; Protect your hands with gloves and/or wrap blade with heavy cloth.

4. Remove blade bolt by turning counter- clockwise.

5. Remove blade and attaching hard- ware (bolt, lock washer and hardened

washer).

TO REPLACE BLADE

1. Position blade on the blade adapter aligning the two (2) holes in the blade

with the raised lugs on the adapter.

2. Be sure the trailing edge of blade (op- posite sharp edge) is up toward the

engine.

3. Install the blade bolt with the lock washer and hardened washer into blade adapter and crankshaft.

4. Use block of wood between blade and

lawn mower housing and tighten the blade bolt, turning clockwise.

• The recommended tightening torque is 35-40 ft. Ibs.

IMPORTANT: Blade bolt is heat treated.

If bolt needs replacing, replace only with approved bolt shown in the Repair Parts section of this manual.

TO SHARPEN BLADE

NOTE: We do not recommend sharpening

the blade - but if you do, be sure the blade

is balanced. Care should be taken to keep the blade

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.

GEAR CASE

• To keep your drive system working

properly, the gear case and area around the drive should be kept clean and free of trash build-up. Clean under the drive

cover twice a season.

• The gear case is filled with lubricant to

the proper level at the factory. The only time the lubricant needs attention is if

service has been performed on the gear case.

• If lubricant is required, use only Texaco

Starplex Premium 1 Grease, Part No.

750369. Do not substitute.

ENGINE LUBRICATION Use only high quality detergent oil rated with

API service classification SFoSJ. Select the oil's SAE viscosity grade according to your

expected operating temperature.

6. Stop adding oil when you reach the FULL mark on the dipstick. Wait a

minute to allow oil to settle.

7. Continue adding small amounts of oil, rechecking the dipstick until oil level

settles at FULL. DO NOT overfill, or engine will smoke heavily from the

muffler on startup.

8. Always be sure to retighten oil dipstick

before starting engine.

9. Reconnect spark plug wire to spark

plug.

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 Change the oilafter every 25 hours ofopera-

tion orat least once a year ifthe lawn mower is not used for 25 hours in one year.

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.

TO CHANGE ENGINE OIL NOTE: Before tipping lawn mower to drain

oil, empty fuel tank by running engine until fuel tank is empty.

1. Disconnect spark plug wire from spark
