HOW TO USE YOUR LAWN MOWER

ENGINE SPEED CONTROL

The engine speed was set at the factory

for optimum performance. 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 cimum-

stances 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 CU'I'rlNG HEIGHT

•Raise wheels for low cut and lower

wheels for high cut.

•Adjust cutting height to suit your require-

ments. Medium position is best for most

lawns.

•To change cutting height, squeeze

adjuster lever toward wheel. Move wheel

up or down to suit your requirements. Be

sure all wheels are in the same setting.

NOTE: Adjuster is properly positioned

when plate tab inserts into hole in lever.

Also, 9-pesition adjusters (if so equipped)

allow lever to be positioned between the

plate tabs. -Plate

•Forward motion will stop when the opera-

tor presence control bar is released. To

stop forward motion without stopping

engine, release the operator presence

control bar slightly until the drive control

disengages. Hold operator presence

control bar down to handle to continue

mowing without self-propelling.

OIL

Yourlawnmowerisshippedwithoutoilin

theengine.

•Be sure mower is level and area around

oil fill is clean.

•Remove engine oil cap w/dipstick and fill

to the full line on the dipstick.

•Use 20 ozs. of oil. For type and grade of

oil to use, see "ENGINE" in Maintenance

section of this manual.

•Pour oil slowly. Do not over fill

•Check oil level before each use. Add oil if

needed. Fill to full line on dipstick.

•To read proper level, tighten engine oil

cap each time.

•Reinstall engine oil cap and tighten.

•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.

GAS

•Fill fuel tank. 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.

WARNING: Experience indicates that al- •

cohol 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 en-

gine while in storage. To avoid engine •

problems, the fuel system should be emp-

tied before storage of 30 days or longer.

Drain the fuel tank, start the engine and let

it run until fuel lines and carburetor are

empty. Use fresh fuel next season. See

Storage Instructions for additional informa-

tion. Never use engine or carburetor

cleaner products in fuel tank or permanent •

damage may occur.

TO START ENGINE

•To start a cold engine, push primer five

(5) times before trying to start. Use a firm

push. This step is not usually necessary

when starting an engine which has

already run for afew minutes.

•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, release operator pres-

ence control bar.

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 starL If you do flood

engine, wait a few minutes before attempt-

ing to start and do not repeat priming steps.

MOWING TIPS

Under certain conditions, such as very tail

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.

For side discharge lawn mowers, cutting

in a counter-clockwise direction, starting

at the outside of the area to be cut,

spreads grass clippings more evenly and

puts less load on the engine. To keep clip-

pings off of walkways, flower beds, etc.,

make the first cuts in a clockwise direc-

tion.

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 catchers 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.

MULCHINGMOWINGTIPS

IMPORTANT:Forbestperformance,keep

mowerhousingfreeofbuilt-upgrassand

trash. Clean UNDERSIDE OF MOWER

HOUSING after each use. See "Cleaning"

in 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 nutri-

ents 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

aftemoon. 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, mow slowly and raise the rear of the

lawn mower one wheel adjuster setting

higher than the front.

•Certain types of grass and grass condi-

tions may require that an area be

mulched a second time to completely

hide the clippings. When doing a second

cut, mow across or 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 grain-

ing 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 manu-

al.

Some adjustments will need to be made

periodically to properly maintain your unit.

All adjustments in the Service and Adjust-

ments section of this manual should be

checked at least once each season.

• Once a year, replace the spark plug,

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.

•Fellow the maintenance schedule in this

manual.

the self lubdcating beatings. If you feel they

must be lubricated, use only a dry, pow-

dered graphite type lubricant sparingly.
