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

gross 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.

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 fillto 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.

_,WARNING: Expedence 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.

MOWINGTIPS

• Under certain conditions, such as very

tall grass, it may be necessary to raise
the height of cut to reduce pushing

eflod 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
usa 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 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 biodegrede 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 eady

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-
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 graining 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-

CATION CHART").

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 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 MOWE R

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.

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 roach
the carburetor. Do not drain the gas tank

and carburetor if using fuel stabilizer.
