BEFORE STARTING ENGINE
OIL (See Fig. 10)
Your lav_nmower is shipped without oil in the engine.
• Be sure mower islevel and area around oil fill is clean.
Remove engine oil cap w/dipstick and ffi! to the full !ine
on the dipstick.
Use20 o_z,,s,of oil. Fortype and grade ofoilto use, see
ENGINE in Customer Responsibilities section of this
manual.
Pouroil slowly. Do not over fill.
• Che_:koil level before each use. Add oi! if needed. Fill
to ful/ line on dipstick.
To read proper level, tighten engine oi! 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. Yeu 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 du_ing 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 stor-
age of 30 days or longer. Drain the fuel tank, start the
engine and let it run until fue! lines and carburetor are
empty. _se fresh fuel next season. See Storage Instruc-
tions for additional information. Never use engine or

OPERATION
MOWING TIPS
Under certain conditions, such asverytall grass, itmay
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 run the lawn mower over the area a second time.
if a trail of clippings is left on the right side of a rear
discharge mower, mow in a clockwise 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.
• Avoidcuttingyouriawnwhenitiswet. Wetgrasstends
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 top 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 wLdthof 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.
Change your cutting pattern 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.

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 cove r
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 turn 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.

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 toallow the stabilizer to reaeh the carburetor. Do
notdrain thegas tank and carburetor ifusingfuel 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 eng ine to cool
before storing in any enclosure.
