BEFORE STARTING ENGINE
OIL (See Fig. 10)
Your lawn mower is shipped without oil in the engine.
Be sure mower islevel and area around oil fillis 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 asvery tall grass, itmay
be necessary to raise the height of cut to reduce
pushing effortand to keep from overloading the engine
and leaving clumps of grass clippings.
For extremely heavy cutting, reduce the width of cutby
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 groundspeed (pushing speed)
and/or runthe lawn mower overthe area a secondtime.
If a trail of clippings is left on the right side of a rear
discharge mower, mow ina clockwise direction with a
small overlap tocollect the clippings onthe next pass.
Pores inclothgrass 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 clippingsand 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 intothe 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 yourlawn when itis 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.

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 ISGRADE 8HEAT 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-
posed. Place center hole of blade over the head ofthe
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.

• 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 a manufacturer
approved replacement catcher. Give the lawn mower
model number when ordering•

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) hoursof continuous use. Tighten oil
plug securely each time you check the oillevel.

• 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.

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.

• 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.
