BEFORE STARTING ENGINE

OIL

Your lawn mower is shipped without oil inthe

engine.

• Be sure mower is level and area around oil

fill is clean.

• Remove engine oil cap and fill to the full

line on the dipstick.

NOTE: Allow oil to settle down into engine

for accurate dipstick 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 overfill.

• Check oil level before each use. Add oil if

needed. Fill to full line on dipstick.

• To read proper level, tighten engine oil cap

each time.

• Reinstall engine oil cap and tighten.

• Change the oilafter every 25 hours of

operation or each season. You may need

to change the oil more often under dusty,

dirty conditions.

ADDGASOLINE

• 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.

&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 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.

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.

Engine oil cap Gasoline filler cap

TO START ENGINE

• 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.

• Turn electric start key clockwise to

crank engine.

IMPORTANT: Do not crank engine more

not crank engine more than five

continous seconds between eack time

you try to start. Wait 5 to 10 seconds

between each attempt.

• To start engine using the auxiliary

starter handle, follow the steps above.

Exchange the use of the start key for

starter handle. 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.

• When using a rear discharge lawn

mower in moist, heavy grass, clumps of

cut grass may not enter the grass

catcher. Reduce ground speed

(pushing speed) and/or run the lawn

mower over the area a second time.

• If a trail of clippings is left on the right

side of a rear discharge mower, mow in

a clockwise direction with a small •

overlap to collect the clippings on the

next pass.

• 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: Forbest 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 fal! 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 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.

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,

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

• Check engine oil level.

• Check for loose fasteners.

LUBRICATION

Keep unit well lubricated (See "LUBRICA-

TION CHART").
