BEFORE STARTING ENGINE

OIL (See Fig. 7)

Your lawn mower 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 fill to the full line

on the dipstick.

° Use20ezs of oil. Fortypeandgradeofoiltouse, see

"ENGINE" in Customer Responsibilities section of this
manual.

° Pour oil stowly 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. 7)

° Fill 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 within 30 days to assure fuel freshness.

WARNING: Experience indicates that alcohol blended
fuels (called gasohel 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 flesh fue_ next season See Storage _nstruc-
tions for additional information. Never use engine or
carburetor cleaner products in fuel tank or permanent

damage may occur.

OPERATION

TO START ENGINE

To start a cold engine, push primer five (5) times before
trying to start. Use a firm push. This step is not usually

necessary when starting an engine which has already
run for a few minutes.

. Hold operator presence control bar down to the handle

and pul! 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 maycause
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

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

o 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 asecond time.

= If a trail ofgrass clippings is left onthe rightside of a 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 less grass.
To prevent this, regularly hose catchers off with water

and let dry before using.

MULCHING MOWING TiPS

IMPORTANT: FOR BEST PERFORMANCE, KEEP

MOWER HOUSING FREE OF BUILT-UP GRASS AND
TRASH CLEAN UNDERSIDE OF MOWER HOUSING
AFTER EACH USE. 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 recurring action of the

blades_

o Avoid cutting your lawn when it is weL 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 top one-third
of the grass blades (See Fig. 8)_ If the lawn is over-
grown 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,
mow slowly and raise the rear of the lawn mower one

wheel adjuster setting higher than the frenL

° 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.

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 agrinding
wheel Do not attempt to sharpen while on the mower.

o To check blade balance, ddve a nailinto a beam orwallo

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_

GRASS CATCHER

o

The grass catcher may be hosed with water, but must
be dry when used.

o

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

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

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 ayear if the lawn

mower is net used for 25 hours in one year.

Check the crankcase oil level before starting the engine

plug securely each time you check the oil level
TO CHANGE ENGINE OIL (See Fig. 10)

NOTE: Before tipping 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

KET

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

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

carburetor are empty.

• Never use engine orcarburetor cleaner products in the
fuel tank or permanent damage may occur,

o 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

o Remove spark plug.
o 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_

with gasoline in the tank inside abuild-
ing where fumes may reach an open

flame or spark. Allow the engine to
