instructions on the machine and in the
manual(s) before starling. Be thor-

oughly familiar with the controls and
the proper use of the machine before

starling.

• Do not put hands or feet near or under

rotating pads. 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.

• Do not pull mower backwards unless

absolutely necessary. Always look
down and behind before and while

moving backwards.

• 'Do not operate the mower without

proper guards, plates, grass catcher or
other safety protective devices in place.

• See manufacturer's instructions for

proper operation and installation of
accessories. Only use accessories
approved by the manufacturer.

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.

II1.CHILDREN

Tragic accidents can occur if the operator

is not alert to the presence of children.
Children are often attracted to the

theengine. 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 lawnmowar 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 not over fill.

NOTE: Allow oilto settle down into
engine for accurate reading. To read

proper level, tighten engine oil cap, then
remove it to road 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 ever./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.

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 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.

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 pdming 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.

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 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 gross.

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 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 biodegrode 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 gross. For

extremely heavy mulching, reduce your
width of cut by overlapping previously

cut path and mow slowly.

• Certain types of gross 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-

lar to 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 groining of the lawn.

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,

clean or replace air filter element and
check blade for wear. A new 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

1. Check engine oil level.

2. Check for loose fasteners.

LUBRICATION
Keep unit well lubricated(See "LUBRI-

CATIONCHART").

ENGINE
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

adiustment.
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 service

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 dirt, 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.

1. Loosen the two (2) handle knobs on
sides of the upper handle and allow
handle to fold down to the rear.

2. Squeeze the bottom ends of lower
handle toward each other until pins in

handle clear the brackets and pivot
entire handle assembly forward and

allow it to rest on mower.

• When setting up your handle from the

storage position, the lower handle will
require manually locking into the
mowing position.

IMPORTANT: When folding the handle

for storage or transportation, be sure to
fold the handle as shown or you may

damage the control cables.

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 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.
