rotating parts. Keep clear of the

discharge-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.

ing mower.

I1. SLOPE OPERATION

Slopes are a major factor related to slip

and fall accidents which can result in

severe injury. All slopes require extra

caution. 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

footing 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

machine.

•Use extra care when approaching blind

corners, shrubs, trees, or other objects

that may obscure vision.

IV. SERVICS

container inside where there is an

open flame, such as a water heater.

• Never run a 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 acciden-

tal starting.

• Keep nuts and bolts, especially blade

attachement bolts, tight and keep

equipment 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

spillage. Allow machine to cool before

storing.

strike an object. Repair, if necessary,

before restarting.

• Never attempt to make wheel height

adjustments while the engine (motor) is

running.

• Grass catcher components are subject

to wear, damage, and deterioration,

which could expose moving parts or

allow objects to be thrown. Frequently

check components and replace with

manufacturer's recommended parts,

when necessary.

• Mower blades are sharp and can cut.

Wrap the blade(s) or wear gloves, and

use extra caution when servicing them.

BEFORE STARTING ENGINE

OIL

Your lawn mower is shipped without oil i

the engine.

•Be sure mower is level and area

around oil fill is clean.

•Remove engine oil cap and fill to the

full line on the dipstick.

NOTE: Allow oil to settle down into

engine for accurate reading.

• Engine holds 27ozs. 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.

• Changethe oil after every 25 hoursof

operation or each season. You may

needto change the oil more often

underdusty, dirty conditions.

ADD GASOLINE

• Fill fuel tank. Use fresh, clean, regular

unleaded gasoline with a minimum 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 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 information. Never use engine

or carburetor cleaner products in fuel tank

or permanent damage may occur.

_I,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.

TO START ENGINE

• To start a cold engine, push primer

three (3) times before trying to start.

Use a firm push. This step is not

usually necessary when starting an

engine which has already run for a few

minutes.

• Move engine speed control lever to fast

position.

• Hold operator presence control bar

down to the handle.

• Turn electric start key clockwise to

crank engine.

IMPORTANT: Do not crank engine more

than five continous seconds between

each time you try to start. Wait 5 to 10

seconds between each attempt.

• To start engine using the auxiliary

starter handle, follow the steps above.

Exchange the use of the start key for

starter handle. 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

• 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

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.

• 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 willrecut the

grass clippings many times and reduce

them in size so that as they fallontothe

lawn they will disperse intothe grass and

notbe noticed. Also, the mulchedgrass

will biodegrade quicklyto providenutrients

forthe lawn. Always mulch with your

highest engine (blade) speed as this will

provide the best recuttingaction of the

blades.

• Avoid cuttingyour lawn when itiswet. Wet

grass tends to form clumps and interferes

with the mulchingaction. The best time to

mow your lawn isthe 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

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

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 second cut, mow

across or perpendicular 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.
