NOTE: Do not drag the bag when emptying; it will cause

unnecessary wear.

BEFORE STARTING ENGINE

OIL (See Fig. 10)

Your lawn mower is shipped without oil in the engine.

Be sure mower is level and area around oil fill is clean.

Remove engine oit cap w/dipstick and fill to the full line

on the dipstick.

Use 20 ozs. of oil. For type and grade of oil to use, see

"ENGINE" in Customer Responsibilities section of this

manual.

•Pour oil 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.

• After the first two (2) hours of mowing, change the oil,

and every 25 hours thereafter. You may need to

change the oil more often under dusty, dirty conditions.

GAS (See Fig. 10)

•Fill gasoline tank with fresh, clean, unleaded gasoline.

DO NOT USE PREMIUM GASOLINE. BE CAREFUL

NOT TO OVER FILL TANK.

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 gf an engine while in storage. To avoid engine

problems, the fuel system should be emptied before stor-

age of 30 days or longer. Drain the fuel tank, start the

engine and let it run until fuel lines and carburetor are

empty. Use fresh fuel next season. See Storage Instruc-

tions for additional information. Never use engine or

carburetor cleaner products in fuel tank or permanent

damage may occur.

OPERATION

MOWING TIPS

Undercertain 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.

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 (,_) posi-

tion.

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 runthe lawn mower ove rthe area a seco ndtime.

If a trail 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 incloth 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 airflow

and extend engine life.

FIG. 11

MULCHING MOWING TIPS

IMPORTANT: FOR BEST PERFORMANCE, KEEP

MOWER HOUSING FREE OF BUILT-UP GRASS AND

TRASH. SEE =CLEANING" IN CUSTOMER

RESPONSIBILITIES SECTION OF THIS MANUAL.

The special mulching blade will recut the grass clip-

pings 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 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 tcp one-third

of the grass blades (See Fig. 11). 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 re-

quire that an area be mulched a second time to com-

pletely hide the clippings. When doing a second cut,

mow across or perpendicular to the first cut path.

• Changeyourcuttingpattemfromweektoweek. 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 ayear, 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 "LUBRICATION CHART").

CUSTOMER RESPONSIBILITIES

LAWN MOWER

Always observe safety rules when performing any mainte-

nance.

TIRES

•Keep tires free of gasoline, oil, or insectcontrol chemi-

cals which can harm rubber.

• Avoid stumps, stones, deep ruts, sharp objects and

other hazards that may cause tire damage.

BLADE CARE

For best results, mower blade must be kept sharp. Re-

place bent or damaged blades.

TO REMOVE BLADE (See Fig. 12)

• 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/orwrap blade with

heavy cloth.

• Remove blade bolt by turning counter-clockwise.

Remove blade and attaching hardware (bolt, lock

washer and i_ardened 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 (See Fig. 12)

• 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.

• B_ sure the trailing edge of blade (opposite sharp

edge) is up toward the engine.

• Install the blade bolt with the Iockwasher 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. Ibs.

IMPORTANT: BLADE BOLT IS GRADE 8 HEAT TREATED.

NOTE: We do not recommend sharpening blade - but if

you do, be sure the blade is balanced.

TO SHARPEN BLADE

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 g rinding

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 ex-

GEAR CASE

•To keep your drive system working properly, the gear

case and area around the drive should be kept clean

and free of trash build-up. Clean under the drive cover

twice a season.

• The gear case is filled with lubricant to the proper level

at the factory. The only time the lubricant needs

attention is if service has been performed on the gear

case.

• If lubricant is required, use only Texaco Starplex Pre-

mium Grease, part no. 750369. Do not substitute.

DRIVE WHEELS

Check front drive wheels each time before you mow to be

sure they move freely.

The wheels not turning freely means trash, grass cuttings,

etc. are in the drive wheel area and must be cleaned to free

drive wheels.

If necessary to clean the drive wheels, check both front

wheels.

•Remove hubcaps, hairpin cotters and washers.

• Remove wheels from wheel adjusters.

• Remove any trash or grass cuttings from inside the

dust cover, pinion and/or drive wheel gear teeth.

• Put wheels back in place.

• If after cleaning, the drive wheels do not tum freely,

contact your nearest authorized service center.

GRASS CATCHER

The grass catcher may be hosed with water, but must

be dry when used.

Check your grass catcher often for damage or deterio-

ration. Through normal use it will wear. If catcher

needs replacing, replace only with amanufacturer

approved replacement catcher. Give the lawn mower

model number when ordering•

CUSTOMER RESPONSIBILITIES

ENGINE

LUBRICATION

Use only high quality detergent oil rated with API service

classification SG. Select the oil's SAE viscosity grade

according to your expected operating temperature.

SAE VISCOSITY GRADES

-30" -20" -I0" 0" 10" 20" 30°

TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE

NOTE: Although multi-viscosity oils (5W30, 10W30 etc.)

improve starting in cold weather, these multi-viscosity oils

will result in increased oil consumption when used above

32°F. Check your engine oil level more frequently to avoid

possible engine damage from running low on oil.

Change the oil after the first two hours of operation and

every 25 hours thereafter or at least once a year if the lawn

mower is not used for 25 hours in one year.

Check the crankcase oil level before starting the engine

and after each five (5) hours of continuous use. Tighten oil

plug securely each time you check the oil level.

TO CHANGE ENGINE OIL (See Fig. 13)

NOTE: Before tipping lawn mower to drain oil, drain fuel

•tank by running engine until fuel tank is empty.

Disconnect spark plug wlm Imm sp_,rkplug _nd pllco

wire where it cannot come in contact with spark plug.

•Remove engine oil cap; lay aside on a clean surface,

• Tip lawn mower on its side and drain oil into a suitable

container. Rock lawn mower back and forth to remove

an}, oil trapped inside of engine,

• Wipe off any spilled oil on lawn mower and on side of

engine.

•Fill engine with oil. Fill only to the "FULL" line on the

dipstick. DO NOT OVER FILL.

• Replace engine oil cap.

• Reconnect spark plug wire to spark plug.

AIR FILTER

Your engine will not run properly and may be damaged by

using a dirty air filter.

Replace the air filter every year, more often if you mow in

very dusty, dirty conditions. Do not wash air filter.

TO CHANGE AIR FILTER (See Fig. 14)

• Remove the air filter cover by turning counterclockwise

to the stop and pull away from collar.

FUEL SYSTEM

IMPORTANT: IT IS IMPORTANT TO PREVENT GUM

DEPOSITS FROM FORMING IN ESSENTIAL FUEL

SYSTEM PARTS SUCH AS CARBURETOR, FUEL FILTER,

FUEL HOSE, OR TANK DURING STORAGE. ALSO,

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.

• Drain the fuel tank.

• Start the engine and let it run until the fuel lines and

carburetor are empty.

• Never use engine or carburetor cleaner products in the

fuel tank or permanent damage may occur.

• Use fresh fuel next season.

NOTE: Fuel stabilizer is an acceptable alternative in

minimizing the formation of fuel gum deposits during stor-

age. Add stabilizer to gasoline in fuel tank or storage

container. Always follow the mix ratio found on stabilizer

container. Run engine at least 10 minutes after adding

stabilizer to allow the stabilizer to reach the carburetor. Do

not drain the gas tank and carburetor if using fuel stabilizer.

ENGINE OIL

Drain oil (with engine warm) and replace with clean engine

oil. (See "ENGINE" in the Customer Responsibilities

section of this manual).

CYLINDER

• Remove spark plug.

• Pour one ounce (29 ml) of oil through spark plug hole

into cylinder.

• Pull starter handle slowly a few times to distribute oil.

Replace with new spark plug.

OTHER

• Do not store gasoline from one season to another.

• Replace your gasoline can if your can starts to rust.

Rust and/or dirt in your gasoline will cause problems.

• If possible, store your unit indoors and cover it to give

protection from dust and dirt.

• Cover your unit with a suitable protective cover that

does not retain moisture. Do not use plastic. Plastic

cannot breathe which allows condensation to form and

will cause your unit to rust.

IMPORTANT: NEVER COVER MOWER WHILE ENGINE

AND EXHAUST AREAS ARE STILL WARM.

CAUTION: Never store the lawn mower

with gasoline in the tank inside a build-

ing where fumes may reach an open

flame or spark. Allow the engine to cool

before storing in any enclosure.
