HOWTO USEYOUR LAWN MOWER

ENGINE SPEED

The engine speed was set at the factory

for optimum performance. Speed is not

adjustable.

ENGINE ZONE CONTROL

_,C.AUTION: 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.

TO ADJUST CUTFING 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-position adjusters (if so equipped)

allow lever to be positioned between the

plate tabs.

BEFORE STARTING ENGINE

OIL

Your lawn mower is shipped without oil in the

engine.

•Be sure mower is level and area around oil

fill is clean.

•Remove engine oilcap and tillto the full

line on the dipstick.

NOTE: Allow oil to settle down into engine

for accurate dipstick reading.

•Engine holds 27 ozs. of oil. For type and

grade of oilto use, see "ENGINE" in

Maintenance section of this manual.

•Pour oil slowly. Do not over 1111.

• Check oil level before each use. Add oil if

needed. Fill to full line on dipslJck.

• 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.

DD GASOLINE

•Fill fuel tank. Use fresh, clean, regular

unleaded gasoline with aminimum of

87 octane. (Use of leaded gasoline

will increase carbon and lead oxide

deposits and reduce valve life). Do not

mix oil with gasoline. 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.

_CAUTION- 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.

Gasoline filler cap Engine oil cap

TO START ENGINE

• TO start a cold engine, push primer three

(3) times before Wing to start. Use a11rm

push. This step is not usually necessary

when starling an engine which has

already run for a few 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 presence

control bar.

NOTE: In cooler weather it may be

necessary 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 attempting to start and do not

repeat priming steps.

MOWING TIPS

• Undercertainconditions,suchasvery

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 (push-

ing 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

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 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

biedegrade 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 dumps and interferes

with the mulching action. The best time to

mow your lawn is the early afternoon. 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 necessa W

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 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 asecond cut, mow

across or perpandicular to the first cut path.

Change your cutting pattem 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. Max 1/3

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

manual.

Some adjustments will need to be made

periodically 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,

replace air filter element and check

blade for wear. Anew 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

• Check engine oil level.

• Check for loose fasteners.

LUBRICATION

Keep unit well lubricated (See "LUBRICA-

TION CHART").

LUBRICATION CHART

(_) Wheel adjuster ine oil

Rear door hinge

(_) Handle bracket mounting pin

(_) Spray lubricant

(_) Refer _o Maintenance "ENGINE" section.

IMPORTANT: Do not oilor grease plastic

wheel bearings. Viscous lubricantswill attract

dust and dirt that 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.
