severe iniury. All slopes require extra

caution. If you feel uneasy on a slope, do

notmow 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 nottrim near dropoffs, ditches or

embankments. The operator could lose

footing or balance.

• Do not trim excessively steep slopes.

•Do not mow on wet grass. Reduced

footing could cause slipping.

BEFORE STARTING ENGINE

ADD OIL

Your lawnmower is shipped without oil in

the engine. Engine holds 20 oz. of oil.

For type and grade of oil to use, see

=ENGINE" in Maintenance section of this

manual.

1. Be sure lawnmower is level and area

around oil fill is clean.

2. Remove engine oil cap and fill to the

full line on the dipstick.Pour oil slowly.

Do notover fill.

NOTE: Allow oil to settle down into engine

for accurate reading. To read proper level,

tighten engine oil cap, then remove it to

read the dipstick.

3. Reinstall engine oil cap and tighten.

• Check oil level before each use. Add

oil ifneeded. Fillto 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.

ADD GASOLINE

•Fillfuel tank. Use fresh, clean, regular

unleaded gasoline with a minimum of

87 octane. Do not mix oil with gaso-

line. Purchase fuel in quantitiesthat

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

formationof acids dudngstorage. 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 untilthe fuel lines

and carburetorare empty. Use fresh fuel

nextseason. See Storage Instructionsfor

additional information. Never use engine

or carburetor cleaner products in the fuel

tank or permanent damage may occur.

CAUTION: Fill tobottomof gas tank

filler neck. Donot overfill. Wipe off any

spilled oil or fuel. Do not store, spillor

use gasoline near an open flame.

TO START ENGINE

NOTE: Due to protective coatingson the

engine, a small amount of smoke may be

present dudng the initial use of the

product and should be considered

normal.

1. To start a cold engine, push pdmer

three (3) times before tryingto start.

Use a firm push. This step is not

usually necessary when starting an

engine which has already runfor 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.

TO STOP ENGINE

•To stop engine, release operator

presence control bar.

NOTE: In cooler weather it may be

necessary to repeat priming steps. In

warmer weather over pdming may cause

flooding and engine will notstart. If you

do flood engine, wait a few minutes

beforeattempting tostart and do not

repeat pdming steps.

MOWlNGTIPS

• Undercertainconditions,suchasvery

tallgrass,itmaybenecessarytoraise

theheightofcuttoreducepushing

effortandtokeepfrom ovedoading the

engine and leaving dumps 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 cot 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

(pushingspeed) and/or nJnthe lawn

mower over the area a second time.

•If a trailof clippingsisleft onthe dght

side of a rear discharge mower, mow in

a clockwise direction with a small

ovedap to collect the clippings on the

next pass.

• Pores in cloth grass catchers can

become filled with dirt and dustwith

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 clippingsand chaff.

This will help engine air flow and

extend engine llfe.

MULCHING MOWING TIPS

IMPORTANT: For best performance,

keep mower housingflee of built-up

grass and trash. See "CLEANING" inthe

Maintenance sectionof this manual.

•The special mulchingblade will recut

the grass clippingsmany times and

reduce them in size so that as they fall

onto the lawn they will disperse intothe

grass and not be noticed.Also, the

mulched grass will biedegrade quickly

to provide nutrientsfor the lawn.

Always mulchwith your highest engine

(blade) speed as this will provide the

best racutting action of the blades.

•Avoid cutting your lawn when it is wet.

Wet grass tends to form clumpsand

interfereswith the mulchingaction. The

besttime to mow your lawn is the eady

afternoon. At this time the grass has

dried and the cewiy cut area will not be

exposed to the direct sun.

•For best results, adjust the lawn mower

cuttingheight so that the lawn mower

cuts off only the top one-third ofthe

grass blades. If the lawn is overgrownit

will be necessary to raise the height of

cut to reduce pushing effort and to keep

from overloading the engine and

leaving dumps 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

conditionsmay require that an area be

mulched asecond time to completely

hide the clippings. When doing a

second cut, mow across or perpendicu-

lar to the first cut path.

•Change your cuttingpattern from week

to week. Mow northto 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

notcover items that have been subjected

• 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

1, Check engine oil level,

2. Check for loose fasteners.
