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

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.

HOW TO USE YOUR LAWN MOWER

ENGINE SPEED

The enginespeed was set at the factory for optimumperformance.Speed is not

adjustable.

ENGINE ZONE CONTROL

_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 bar up to the handle. The closer to the handle the bar is pulled, the faster

the unit will travel.

• Forward motion will stop when either the

operator presence control bar or drive control bar are released. To stop forward

motion without stopping engine, release the drive control bar only. Hold operator

presence control bar down against handle to continue mowing without self-

propelling.

NOTE: If after releasing the drive control the mower will not roll backwards, push

the mower forward slightly to disengage drive wheels.

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.

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 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. See =TO

CHANGE ENGINE Oil." in the Mainte-

nance section of this manual. ATTACH FUEL CAP CARTRIDGE Your mower is equipped with a special

FRESH START TM fuel cap and continuous

fuel preserver cartridge. See the infor-

mation and instructions packed with the FRESH STAR'l'_ cartridge.

1. Snap cartridge into bottom of fuel cap. NOTE: Do not remove the silver foil seal on

the side of cartridge that snaps into fuel cap.

2. Grasp the white peel tab and pull to

remove the entire seal.

3. Screw fuel cap onto fuel tank after fill-

ing tank with gasoline.

Replace cartridge when empty (about once

a season). Check preserver level visually. A DANGER: Cartridge fluid is HARMFUL

OR FATAL IF SWALLOWED. Avoid contact

to eyes, skin, or clothing. Do not take

internally. Do not inhale fluid vapor. Keep out of reach of children. If swallowed, call

a physician immediately. 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.

CAUTION: Wipe off any spilled oil or

fuel. Do not store, spill or use gasoline ,_ar an open flame.

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 in the fuel

10tank or permanent damage may occur.

NOTE: _ncoolerweatheritmay benecessary to repeat primingsteps. In warmer weather

overprimingmaycauseflooding andengine will not start. If you do flood engine, wait a few minutesbefore attemptingto start and

do notrepeat primingsteps.

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 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.

• Pores in cloth grass catchers can be- come filled with dirt and dust with use

and catchers witl collect less grass. To prevent this, regularly hose catcher off

with water and let dry before using. 11

• Keep topof engine around starterclear and clean of grassclippingsand chaff.

This willhelp engine air flow and extend

engine life.

MULCHING MOWING TIPS IMPORTANT: For best performance,

keep mower housingfree of built-up grassand trash.See =CLEANING" in the

Maintenance sectionof thismanual.

• The specialmulchingblade willrecut

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 itis 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.

• 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.

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 hardware (bolt, lock washer, hardened washer).

NOTE: Remove the blade adapter and

check the key inside hub of blade adapter. The key must be in good condition to work

properly. Replace adapter ifdamaged.

TO REPLACE BLADE

1. Position the blade adapter on the en- gine crankshaft. Be sure key in adapter

and crankshaft keyway are aligned.

2. Position blade on the blade adapter

aligning the two (2) holes in the blade with the raised lugs on the adapter.

TO SHARPEN BLADE NOTE: We do not recommend sharpening

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, itshould 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 isfilled 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.
