BEFORE STARTING ENGINE
OIL

Yourlawnmower isshippedwithoutoilinthe
engine.

• Be sure mower is leve] and area

around oil fill isclean.

• Remove engine oilcap and fill to the

full line on the dipstick.

NOTE: Allow oilto settledown into
engine for accurate dipstickreading.

• Engine holds 20 ozs. of oil. For type
and grade of oil to use, see "ENGINE"
in Maintenance section of this manual

• Pour oil slowly. Do not over fill

• Check oil level before each use. Add
oil if needed. Filltofull line on dipstick.

• To read proper level, tighten engine oil
cap each time.

• Reinstall engine oil cap and tighten.

• Change the oil after every 25 hoursof

operationor each season. You may
need to change the oil more often

under dusty, dirty conditions.

ADD GASOLINE

• 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 within30 days to assure fuel

freshness.

_.WARNING: Experience indicatesthat
alcohol blended fuels (called gasehol or

using ethanol or methanol) can attract
moisturewhich leads to separation and

formationof acids duringstorage. Acidic
gas can damage the fuel system of an
engine while in storage. To avoid engine

problems, the fuel system shoutd be
emptied before storage of 30 days or
longer. Drain the gastank, start the
engine and let it run untilthe fuel lines

and carburetorare empty. Use fresh fuel
nextseason. See Storage Instructions for
additional information. Never use engine

or carburetorcleaner productsin the fuel
tank or permanent damage may occur.

ACAUTION: Fill to bottomof gas tank

filler neck. Do not overfill. Wipe off any

spilled oil or fuel. Do not store, spillor use
gasoline near an open flame.

TO START ENGINE
NOTE: Due to protective coatingson the

engine, a small amount of smoke may be
present duringthe initialuse of the

normal.

• To start a coldengine, push primer

three (3) times before fryingto start. Use

a firm push. This step is not usually
necessary when starting an engine
whichhas already runfor a few

minutes.

• Hold operator presence controlbar

handle quickly. Do not allow starter
rope to snap back.

• To stop engine, release operator

presence control bar.

NOTE: In coolerweather it may be
necessary to repeat primingsteps. In

MOWINGTIPS

• Under certain conditions,such as very
tall grass, it may be necessary to raise

the height of cut to reduce pushing
effortand to keep from ovedoading the

engine and leaving clumps of grass
clippings. It may also be necessary to

reduce ground speed and/or run the
lawn mower over the area a second

time.

• Forextremely heavy cutting,reduce the

width of cut by overlapping previously
cut path and mow slowly.

• For better grass baggingand most

cuttingconditions, the engine speed
shouldbe 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

(pushingspeed) and/or run the lawn
mowerover the area a secondtime.

• If a trailofclippingsisleft on the right
side of a rear discharge mower, mow in

a clockwisedirectionwith a small
ovedap to collect the clippingson the

next pass.

• Pores in cloth grass catcherscan
become filled with dirtand dust with use

and catchers witlcollactless grass. To
prevent this, regularly hose catcher off

with water and let dry before using.

• Keep top of enginearound starterclear

and clean of grass clippingsand chaff.
This will help engine air flow and

extend engine lite.

MULCHINGMOWINGTtPS
IMPORTANT: For best performance,keep

mower housingfree of built-upgrass and
trash. Clean UNDERSIDE OF MOWER

wrap blade with heavy cloth.

• Remove blade bolt by turning counter-

clockwise.

• Remove blade and attaching hardware

(bolt,lock washer and hardened
washer).

NOTE: Remove the blade adapter and
check the key inside hub of blade adapter.
The key mustbe in good conditionto work
prepedy. Replace adapter if damaged.

TO REPLACE BLADE

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.

• Be sure the trailing edge of blade

(opposite sharp edge) is up toward the
engine.

• Install the blade bolt with the lock

washer and hardened washer into
blade adapter and crankshaft.

TO SHARPEN BLADE

NOTE: We do not recommend
sharpeningblade - but if you do, be sure

the blade is balanced.
Care shouldbe 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 grindingwheel. Do notattempt
to sharpen while on the mower.

• To check blade balance, ddve a nail
intoa beam or wall. Leave about one

inch of the straight nail exposed. Place
center hole of blade over the head of

the nail. Ifblade isbalanced, it should

remain in a horizontalposition. If either

end of the blade moves downward,
sharpen the heavy end untilthe blade

is balanced.

possible engine damage from running

tow on oil.
Change the oil after every 25 hoursof

operationor at least once a year if the

lawn mower is not used for 25 hours in

one year.

Check the crankcase oil level before

FUEL SYSTEM
IMPORTANT: Itis importantto prevent

gum depositsfrom 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 gasohof or using
ethanol or methanol) can attract moisture
which leads to separation and formation

of acids duringstorage. Acidicgas can
damage the fuel system of an engine

while in storage.

• Drain the fuel tank.

• Start the engineand let it run untilthe
fuel lines and carburetorere empty.

• Never use engine or carburetorcleaner

productsin the fuel tank or permanent
damage may occur.

• Use fresh fuel nextseason.
NOTE: Fuel stabilizeris an acceptable

alternative in minimizing the formation of
fuel gum deposits during storage. Add

stabilizerto gasolinein fuel tank or
storage container. Alwaysfollow the mix

ratiofound on stabilizer container. Run

ep_jineat least 1(} minutesafter adding

stabilizerto aflow the stabilizerto reach
the carburetor. Do notdrain the gas tank

and carburetorif using fuel stabilizer.
