trouble.

• Always wear safety goggles or safety

glasses with side shields when operat-

ing mower.

II. 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.

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.

Do not change the engine governor

setting or overspeed the engine.

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 oil plug and fill to the

top of slot in filler hole.

NOTE: Allow oil to settle down into

engine for accurate reading.

• Engine holds 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.

• Reinstall engine oil plug 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.

ADD GASOUNE

• Fill fuel tank. Use fresh, clean, regular

unleaded gasoline with a minimum of

87 octane. Do not mix oil with gasoline.

Purchase fuel in quantities that can be

used within 30 days to assure fuel

freshness.

AWARNING: 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.

ACAUTION: 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

NOTE: Due to protective coatings on the

engine, a small amount of smoke may be

present during the initial use of the

product and should be considered

normal.

• 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.

• 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

• 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.

• 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 clippings off of

walkways, flower beds, etc., make the

first cuts in a clockwise direction.

• 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 recur 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 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

by overlapping previously cut path and

mow slowly.

• 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 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.

service center, which has proper equip-

ment and experience to make any

necessary adjustments.

LAWN MOWER

When lawn mower is to be stored for a peded

of time, clean it thoroughly,remove all dirt,

grease, leaves, etc. Store ina clean, dry

area.

•Clean entire lawn mower (See "CLEAN-

ING" in the Maintenance section of this

manual).

•Lubricate as shown in the Maintenance

section of this manual.

• Be sure that all nuts,belts, screws, and

pinsare securely fastened. Inspect

moving parts for damage, breakage and

wear. Replace if necessary.

•Touch up all rusted or chipped paint

surfaces; sand lightlybefore painting.

HANDLE

You can fold your lawn mower handle for

storage.

• Squeeze the bottom ends of the lower

handle toward each other until the lower

handle clears the handle bracket, then

move handle forward.

• Loosen upper handle mounting bolts

enough to allow upper handle to be folded

back.

ENGINE

FUEL SYSTEM

IMPORTANT: It is important to prevent gum

deposits from forming in essential fuel system

parts such as carburetor, fuel filter, fuel hose,

or tank during storage. Also, 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.

• Drain the fuel tank.

• Start the engine and let it run until the fuel

lines and carburetor are empty.

• Never use engine or carburetor cleaner

products in the fuel tank or permanent

damage may occur.

• Use fresh fuel next season.

NOTE: Fuel stabilizer is an acceptable

alternative in minimizing the formation of fuel

gum deposits during storage. Add stabilizer

to gasoline in fuel tank or storage container.

Always follow the mix ratio found on stabilizer

container. Run engine at least 10 minutes

after adding stabilizer to allow the stabilizer to

reach the carburetor. Do not drain the gas

tank and carburetor if using fuel stabilizer.

ENGINEOIL

Drain oil (with engine warm) and replace with

clean engine oil. (See "ENGINE" in the

Maintenance section of this manual).

CYLINDER

• Remove spark plug.

• Pour one ounce (29 ml) of oil through

spark plug hole into cylinder.

• Pull starter handle slowly a few times to

distribute oil.

•Replace with new spark plug.

OTHER

• Do not store gasoline from one season to

another.

• Replace your gasoline can if your can

starts to rust. Rust and/or dirt in your

gasoline will cause problems.

• If possible, store your unit indoors and

cover it to give protection from dust and dirt.

• Cover your unit with a suitable protective

cover that does not retain moisture. Do not

use plastic. Plastic cannot breathe which

allows condensation to form and will cause

your unit to rust.
