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.

• Do not operate the mower when

barefoot or wearing open sandals.

Always wear substantial foot wear.

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

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 NOT:

• Do not trim near drop-offs, ditches or

embankments. The operator could lose

footing or balance.

• Do not tdm 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
comers, shrubs, trees, or other objects

that may obscure vision.

IV. SERVICE

• Use extra care in handling gasoline

and other fuels. They are flammable
and vapors are explosive.

-Use only an approved container.

-Never remove gas cap or add fuel

with the engine running. Allow

engine to cool before refueling. Do

not smoke.

• Keep machine free of grass, leaves, or
other debds build-up. Clean oil or fuel

spillage. Allow machine to cool before
storing.

• Stop and inspect the equipment if you

stdke 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
ADD OIL

Your lawnmower is shipped without oil in
the engine. Engine holds 20 oz. of oil.

For type and grade of oilto use, see

"ENGINE" in Maintenance section of this
manual.

1. Be sure lawnmower is level and area
around oil fig is clean.

2. Remove engine oil cap and fill to the
full line on the dipstick. Pour oil

slowly. Do not over 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 if needed. Fill to 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

• Fill fuel tank. Use fresh, clean, regular
unleaded gasoline with a minimum of

87 octane. Do not mix oil with gaso-
line. Purchase fuel in quantities that

can be used within 30 days to assure
fuel freshness.

_I_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 dudng 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
usa 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.

1. 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.

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 net start. If you
do flood engine, wait a few minutes

before attempting to start and do not
repeat priming steps.

R

MOWINGTIPS

• 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 ofthe 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 MOWINGTIPS

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

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 perpendicu-
larto 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 graining of the lawn.

ENGINE SPEED

Your engine speed has been factory set.

Do not attempt to increase engine speed

or it may result in personal injury. If you

believe that the engine is running too fast

or too slow, take your lawn mower to an
authorized service center for repair and

adjustment,

14

CARBURETOR

Your carburetor has a non-adjustable
fixed main jet for mixture control. If your

engine does not operate properly due to
suspected carburetor problems, take your

lawn mower to an authorized sen/ice
center for repair and/or adjustment.
IMPORTANT: Never tamper with the

engine governor, which is factory set for
proper engine speed• Overspeeding the

engine above the factory high speed
setting can be dangerous. If you think the

engine-governed high speed needs
adjusting, contact your nearest autho-

rized service center, which has proper

equipment and experience to make any

necessary adjustments.

Immediately prepare your lawn mower for

storage at the end of the season or if the
unit will not be used for 30 days or more.

LAWN MOWER

When lawn mower is to be stored for a
period of time, clean it thoroughly, remove
all did, grease, leaves, etc. Store in a

clean, dry area.

1. Clean entire lawn mower (See
"CLEANING" in the Maintenance

section of this manual).

2. Lubricate as shown in the Mainte-
nance section of this manual.

3. Be sure that all nuts, bolts, screws,
and pins are securely fastened.
Inspect moving parts for damage,

breakage and wear• Replace if
necessary.

4. Touch up all rusted or chipped paint

surfaces; sand lightly before painting.

HANDLE
You can fold your lawn mower handle for

storage.

t. Squeeze the bottom ends of the lower

handle toward each other until the
lower handle clears the handle

bracket, then move handle forward.

2. Loosen upper handle mounting bolts
enough to allow upper handle to be

folded back.

IMPORTANT: When folding the handle
for storage or transportation, be sure to

fold the handle as shown or you may

damage the control cables.

• When setting up your handle from the

storage position, the lower handle will
automatically lock into the mowing
position.

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.

1. Drain the fuel tank•

2. 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 !0 minutes after adding

stabilizer to allow the stabilizer to reach

the carburetor. Do not drain the gas tank

and carburetor if using fuel stabilizer.
