BEFORE STARTING ENGINE

OIL

Your lawn mower is shipped without oil in the

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 27 oz& of oil. For type and

grade of oil to use, see "ENGINE" in

Maintenance section of this manual.

° Pour oi! slowly. Do not over fill.

° 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 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

o FTttfuel 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 fLiels (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.

Gasoline filler cap Engine oilcap

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 runfor a few minutes.

° 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, 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

o 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,

o For extremely heavy cutting, reduce the

width of cut by overlapping previously

cut path and mow slowly.

o For better grass bagging and most

cutting conditions, the engine speed

should be set in the fast position.

o When using a rear discharge lawn

mower in moist, heavy grass, clumps of

cut grass may not enter the grass

catcher. Reduce ground speed (push-

ing 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 dpj before using.

oKeep 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; For best performance, keep

mower housing free of built-up grass and

trash. See "Cleaning" in Maintenance section

of this manual,.

oThe 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

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 isthe eady aftemoon_ 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 hearty mulching,

reduce your width of cut by overlapping

previously cut path and mow slowly°

oCertain 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 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

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.

o 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")°
