limbs, etc.

•Watch for holes, ruts, or bumps. Tall

grass can hide obstacles.

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 oi! 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 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 dipstick reading. To read

proper level, tighten engine oil cap, then

remove itto 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

NOTE: Before filling fuel tank, remove

and discard the debris plug that is inside

the tank.

•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.

_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.

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. Move handle mounted throttle control

lever to fast position.

3. Hold operator presence control bar

down to the handle.

4. Turn electric start key clockwise to

crank engine.

IMPORTANT:Donot crank engine more

than five continous seconds between

each time you try to start. Wait 5 to 10

seconds between each attempt.

1. 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

•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.

MOWINGTIPS

• Under certain conditions, such as very

tail 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 asecond time.

•If a trail of clippings is left on the dght

side of a rear discharge mower, mow in

a clockwise direction with a small

ovedap 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: For best performance,

keep mower housing free of built-up

grass and trash. See "Cleaning" in

MAINTENANCE section of this manual.

•The special mulchingblade will reoutthe

grass clippingsmany times and reduce

them insize so that as they fallontothe

lawnthey willdisperseintothe grass and

notbe noticed.Also,the mulched grass will

biedegradequicklyto provk:lanutrientsfor

the lawn. Always mulch withyour highest

engine (blade) speed as this will provide

the best recuttJngactionof the blades.

•Avoidcuttingyour lawnwhen itiswet. Wet

grass tendsto formclumpsand interferes

withthe mulchingaction.The besttime to

mow your lawn isthe earlyaftemcon. At

this timethe grass has dried and the newly

cut area will not be exposed to the direct

sun.

•For best results,adjust the lawn mower

cuttingheightso thatthe lawn mower cuts

off onlythe top one-thi,'d ofthe grass

blades. Ifthe lawn isovergrownit will be

necessary to raisethe heightofcut to

reduce pushingeffortand to keep from

overloading the engine and leaving

clumps ofmulchedgrass. For extremely

heavy mulching,reduce your width ofcut

by overlappingpreviouslycut path and

mow slowly.

• Certain types of grass and grass condi-

tions 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 firstcut path.

• Change your cutting pattem from week to

week. Mow nor_ to south one week then

change toeast towest the next week. This

will help prevent matting and grainingof

the lawn.
