• Be sure mower is level and area around oil

fillis clean.

•Remove engine oilcap and fillto the full

lineon the dipstick.

NOTE: Allow oil to settle down into engine

for accurate dipstick reading.

•Engine holds 27 ozs. of oil. Fortype and

grade of oilto use, see "ENGINE" in

Maintenance section of this manual.

•Pouroil slowly. Do notover fill

•Check oil level before each use. Addoilif

needed. Fillto full line on dipstick.

•To read proper level,tighten engine oilcap

each lime.

•Reinstall engine oil cap and _htan.

•Change the oilafter every 25 hours of

operation or each season. You may need

to change the oil more often under dusty,

dirty conditiorls.

ADO GASOUNE

•Fillfuel tank. Use fresh, dean, regular

unleaded gasolinewith a minimum of 87

octane. Do not mix oil with gasoline.

Purchase fuel in quantitiesthat can be

used within30 days to assure fuel

freshness.

WARNING: Experience indicatesthat

elcohol blended fuels (called gasohol or

using ethanol or me_an_ can attract

moisture which leads to separation and

formation of acids duringstorage. Acidic gas

can damage the fuel system of an engine

while in storage. To avoid engine problems,

the fuel system should be embed before

storage of 30 days or longer. Drain the gas

tank, startthe engine and let itrun untilthe

fuel linesand carburetor are empty. Use

fresh fuel next season. See Storage

Inskuc_onsfor add_ information. Never

use engine or carburetor cleaner productsin

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.

Gasolinefillercap Engineoilcap

TO START ENGINE

•TO start a cold engine, push pdmer three

(3) times beforetryingto start. Use a firm

push. This step isnot usuallynecessary

when starling an engine which has

aJreadyrun for afew minutes.

•Hold operator presence controlbar down

to the handle and pull starter handle

quickly. Do not allow starter ropeto snap

beck.

•To stop engine, release operator presence

contral 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 (push-

ing speed) and/or run the lawn mower

over the area a second time.

• If atrail of clippings is left on the right

side of a rear discharge mower, mow in

aclockwise 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: For best performance, keep

mower housingfree of built-upgrass and

trash. See "Cleaning" in Maintenance section

ofthis manual.

•The special mulching blade willrecutthe

grass clippingsmany times and reduce

them in size so that as they fall ontothe

lawn they will disperse intothe grass and

not be noticed. Also, the mulched grass will

biodegrade quicklyto provide nutrientsfor

the lawn. Always mulchwith yourhighest

engine (blade) speed as thiswill providethe

best recuttingactionofthe blades.

• Avoid cuttingyour lawn when itis wet. Wet

grass tends toform dumps and interferes

withthe mulchingaction. The besttime to

mow your lawn isthe early afternoon. At

this time the grass has dried and the newly

cutarea willnot be exposed to the direct

sun.

•For best results,adjust the lawn mower

cuttingheight so that the lawn mower cuts

offonlythe top one-third ofthe grass blades.

Ifthe lawn isovergrown itwillbe necessary

to raise the height ofcutto reduce pushing

effort and to keep from overloadingthe

engine and leaving clumpsof mulched

grass. For extremely heavy mulching,

reduce yourwidthof cutby overlapping

previously cutpath 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.
