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 oil to 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

•Fillfuel 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").
