•Engineholds 27 ozs. of oil. For typeand

grade of oilto use, see "ENGINE" in

Maintenancesectionof this rnadual.

•Pouroil slowly. Do notover fill.

•Reinstallengine oil cap and tighten,

•Change the oilafterovery 25 hoursof

operationor each season. You may need

to change the oil more often underdusty,

dirty conditions.

GAS

•RIIfuel tank. Use fresh, dean, regular

unleaded gasolinewith a minimum of 87

octane. (Use of leaded gasolinewill

increase carbon and lead oxide deposits

and raduce valve life). Do notmix oilwith

gasoline. Purchasefuel in quantitiesthat

can be usedwithin30 daysto assure fuel

frashnees.

_WARNING: Ex_'.ence indicatesthat

alcoholblended fu_;is(called gasohol or

usingethanolor methanol)can attract

moisture which leads to seperationand

formation ofacidsduringstorage. Acidicgas

can damage the fuel systemof 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, startthe engine and let it run until the

MOWING TIPS

• For mostcuttingconditionsand better

baggingperformance,the engine speed

shouldbe set inthe fast position.

•Undar certaincenditJorts,such as when

mowingverytall grass, raisethe mower

heighton the firstcutto reducepushing

effort,to avoid overheatingthe engine, and

to avoid leavingdumps of grassclippings.

Make the secondcuttothe desiredheight.

•For exb'emelyheavy cutting,reducethe

w_h of cut.

•Pores inclothgrasscatcherscan become

filledwithdirtand dustwithuseand the

catcherwillcollectlessgrass. To prevent

this, regularlyhose catcheroffwithwater

and letdrybeforeuse.

MULCHING MOWING TIPS

IMPORTANT: For bestperformance,keep

mower housingfree of built-upgrassand

bash. See "Cleaning" in MAINTENANCE

sectionof thismanual.

•The specialmulchingblade will recutthe

grass clippingsmany times and reduce

them insize sothat as theyfallontothe

lawn they will disperseintothe grassand

not be noticed, Also, the mulchedgrass

willbiodegradequicklyto providenubients

for the lawn. Always mulchwithyour

highestengine (blade)speed as this will

providethe bestrecuttingactionof the

blades.

• Avoid cutting your lawn when it is wet. Wet

grass tends to form dumps and interferes

with the mulching action. The best time to

mow your lawn is the early afternoon. At

this time the grass has driedand the newly

cutarea willnotbe exposedto the direct

SUn.

•For bestresults,adjustthe lawn mower

cuttingheight so that the lawn mower cuts

offonlythe topone-thirdof the grass

blades. If the lawn is overgrownitwillbe

necessaryto raisethe heightofcutto

reducepushingeffortand to keepfrom

overloadingthe engine and leaving

clumpsof mulchedgrass.For extremely

heavy mulching,reduceyour width of cut

by overlappingpreviouslycut pa_ _md

moo slowly.

•Certaintypesof grassand grass cond_ons

may requirethat an area be mulcheda

secondtime to completelyhidethe

clippings. When doing asecond cut,mow

acrossor perpendicularto the tirstcutpath.

•Change yourcuttingpattemfmmweekto

week. Mow northto southone weak than

change toeast to westthe nextweak. This

willhelp prevent matting and grainingof

the lawn.

All adjustments in the Service and Adjust-

ments sec_on of this manual should be

checked atleestonce e,ad_ season.

•Once a year, replace the spark plug,

replace air filter element and check blade for

wear. A new spark plug and dean/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.

any maintenance.

TIRES

• Keep tires free of gasoline, oil, or insect

control chemicals which can harm rubber.

• Avoid stumps, stones, deep ruts, sharp

objects and other hazards that may cause

tiredamage.

BLADE CARE

For best results, mower blade must be

kept sharp. Replace bent or damaged

blades.

TO REMOVE BLADE

•Disconnect spark plug wire from spark

plug and place wire where it cannot

come in contact with spark plug.

•Turn lawn mower on its side. Make sure

air filter and carburetor are up.

•Use a wood block between blade and

mower housing to prevent blade from

turning when removing blade bolt.

•Protect your hands with gloves and/or

wrap blade with heavy cloth.

•Remove blade bolt by turning counter-

clockwise.

•Remove blade and attaching hardware

(bolt, lock washer and hardened

washer).

NOTE: Remove the blade adapter and

check the key inside hub of blade adapter.

The key must be in good condition to work

properly. Replace adapter if damaged.

TO REPLACE BLADE

•Position the blade adapter on the engine

crankshaft. Be sure key in adapter and

crankshaft keyway are aligned.

•Position blade on the blade adapter

aligning the two (2) holes in the blade

with the raised lugs on the adapter.

• Be sure the trailing edge of blade

(opposite sharp edge) is up toward the

engine.

•Install the blade bolt with the lock

washer and hardened washer into blade

adapter and crankshaft.

•Use block of wood between blade and

lawn mower housing and tighten the

blade bolt, turning clockwise.

•The recommended tightening torque is

35-40 ft. tbs.

IMPORTANT: BLADE BOLT IS GRADE 8

HEAT TREATED.

TO SHARPEN BLADE

NOTE: We do not recommend sharpening

blade -but if you do, be sure the blade is

balanced.

Care should be taken to keep the blade

balanced. An unbalanced blade will cause

eventual damage to lawn mower or

engine.

• The blade can be sharpened with a file

or on a grinding wheel. Do not attempt

to sharpen while on the mower.

•To check blade balance, drive a nail into

a beam or wall. Leave about one inch of

the straight nail exposed. Place center

hole of blade over the head of the nail.

If blade is balanced, it should remain in

a horizontal position. If either end of the

blade moves downward, sharpen the

heavy end until the blade is balanced.

Blade Crank-

adapter shaft

keyway

• If you remove the drive pinions, wipe

clean with dry cloth. Reassemble dry.

Do not lubricate. Do not use oil or

grease.

•The pinion gear, on both sides of the

mower, are the same, however, they

must be installed correctly, If installed

incorrectly, the drive system will not

work.

•There are arrows embossed on both

sides of the pinion gear. With the arrow

at the top of the pinion, the arrow must

point towards front of mower. If the

arrow points to the rear, turn the pinion

around and assemble to mower.

•Place wheels back on adjuster axles.

•Replace Iocknuts and hubcaps.

GRASS CATCHER

•The grass catcher may be hosed with

water, but must be dry when used.

•Check your grass catcher often for

damage or deterioration. Through

normal use it will wear. If catcher needs

replacing, replace only with a manufac-

turer approved replacement catcher.

Give the lawn mower model number

when ordering.

DRIVE WHEELS

Check rear drive wheels each time you

mow to be sure they move freely. The

wheels not turning freely means trash,

grass cuttings, etc., may be inside the

drive wheel and dust cover area and must

be cleaned out to free drive wheels.

If necessary to clean the drive wheels, "

check both rear wheels.

• Remove hubcaps and Iocknuts.

•Remove wheels from wheel adjuster

axles.

•Remove any trash or grass cuttings from

inside the dust cover, pinion and/or drive

wheel gear teeth.

Check your engine oil level more frequently to

avoid possible engine damage from running

low on oil.

Change the oil after every 25 hours of

operalion or at least once a year if the lawn
