BEFORE ,STARTING ENGINE

OIL (See Fig, 9)
Your lawn mower _sshipped without oil in the engine,

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

- Remove engine oil cap w/dipstickand fill to the full line
on the dipstick.

, Use 27 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 fit!.

• Check oil leve 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. 9)

- Fii fuel tank. Use fresh, clean, regular unleaded

gasoline with a minimum of 87 octane. Do'not mix oil
with gasoline. Purchase fuel in quantities that can be

used w_thin 30 days to assure fuel freshness.

IMPORTANT: WHEN OPERATING IN TEMPERATURES
BELOW 32°F(0°C), USE FRESH, CLEAN WINTER GRADE

GASOLINE TO HELP INSURE GOOD COLD WEATHER
STARTtNG

WARNING: Experience indicates that alcohol blended
fuels (calfed gasohof 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. 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 engrne or

carburetor cleaner products in fuel tank or permanent
damage may occur.

TO START ENGINE

To start acold engine, push primer five (5) times before
[rying to start. Use a firm push. This step is not usually
necessary when starting an eng_ne which has already

run for a few minutes.

- Move engine speed control lever to fast (,t_) position.

- Hold operator presence control bar down to the handle
and pull starter handle quickly. Do not allow starter

rope to snap back.

- To stop engine, release operator presence control 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

o Under certain conditions, such as very tall 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 ofcut

and raise the rear of the lawn mower housing one (1)
wheel adjuster setting higher than the front for better

discharge of grass.

= For better grass bagging and most cutting conditions.

Lheengine 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 (pushing speed)
and/or run the lawn mower over the area a second time.

• Ifa trail of grass clippings is lefton the rignt side ofa rear

discharge lawn mower, mow in a clockwise direction
with a small overlap to collect the clippings on the next

pass.

• Keep top of engine around starter clear and clean of

grass clippings and chaff. This will help engine airflow
and extend engine life.

, Pores in cloth grass catchers can become filled with dirt

and dust with use and catchers will collect tess grass,
To prevent this, regularly hose catchers off with water
and let dry before using.

OPERATION

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 andreduce 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 wii
biodegrade quickly to provide nutrients for the lawn,
Always mulch with your highest engine (blade) speea

as this wil provide the best recutting action of the
blades.

- Avoid cuttin gyour lawn when itis wet. Wet grass tends
to form clumps and interferes with the mulching action.
The best time to mow your lawn isthe earty afternoon.
At this time the grass has dried and the newly cut area
will nor be exposed to the direct sun.

, For best results, adjust the lawn mower cutting height

so that the !awn mower cuts off only the top one-third
of the grass blades (See Fig. 10). 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 ot 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 yourcutting 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.

GRASS CATCHER

(If pureqased as an accessory)

- 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 norma use it will wear. If catcher
needs replacing, replace only with a manufacturer

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

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 inthe 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.

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 lulcricant 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 1 Grease. Part No. 750355. Do not substitute.

TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE

NOTE: Although multi-viscosity oils (5W30, 10W30 etc.)
improve starting in cold weather, these multi-viscosity oils

wil! result in increased oi! 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

p!ug securely each time you check the oil level.
TO CHANGE ENGINE OiL (See Fig, 12)

NOTE: Before tippmg lawn mower to drain oil, drain fuel
tank by running engine until fuel tank is empty.

Disconnect spark plug wire from spark plug and place
w_rewhere t cannot come in contact with spark plug.
