OPERATION
HOW TO USE YOUR LAWN MOWER
ENGINE SPEED (See Fig. 2)
The engine speed is controlled by a lever located on the
side ofthe engine. Fast (_) position is for starting engine,
normal cutting and better grass bagging. Slow (,a_)
position is for light cutting, trimming and fuel economy.
ENGINE ZONE CONTROL
CAUTION: Federal regulations require
an engine control to be installed on this
|awn mower in order to minimize the
risk of blade contact injury. Do not un-
der any circumstances attempt to de-
feat the function of the operator control.
The bJade turns when the engine is
running.
Your lawn mower is equipped with an operator pres-
ence control bar which requires the operator to be
positioned behind the lawn mower handle to start and
operate the lawn mower.
TO ADJUST CUTTING HEIGHT (See Fig. 3)
Raise wheels for low cut and lower wheels for high cut.
• Wheels are set in low cut for shipping. Adjust cutting
height to suit your requirements. Medium position is
best for most lawns.
To change cutting height, squeeze adjuster lever to-
ward wheel. Move wheel up or down to suit your
requirements. Be sure all wheels are in the same
setting.
BEFORE STARTING ENGINE
OHL (See Fig. 4)
Your lawn mower is shipped without oil in the engine.
Be sure mower is level and area around oil fill is clean.
Remove engine oil cap w/dipstick and fill to the full line
on the dipstick.
Use20ozs. of oil. Fortypeandgradeofoiltouse, see
"ENGINE" in Customer Responsibilities section of this
manual
oPour oil slowly. Do not over fill.
o 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.
o 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
changethe oil more often under dusty, dirty conditions.

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 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 engine or
carburetor cleaner products in fuel tank or permanent
damage may occur,

OPERATION
TO START ENGINE
o 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.
•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, tn warmer weather over priming may cause
flooding and engine will not start. If you de flood engine
wait a few minutes before attempting to start and DO NOT
repeat priming steps.
MOWING TiPS
•Under certain conditions, such as very tatl 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 h(gher than the front for better
discharge of grass.
-For better grass bagging and most cutting conditions,
the engine speed should be set inthe fast (_) position.
• For side discharge lawn mowers, cutting in a counter-
clockwise direction, starting at the outside of the area
to be cut, spreads grass clippings more evenly and
puts less load on the engine. To keep clippings off of
walkways, flower beds, etc., make the first cuts in a
clockwise direction,
• 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 air flow
and extend engine life.

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 ifthe 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
plug securely each time you check the oil level,

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: Fue! 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.
ENGUNE OiL
Drain oil (with engine warm) and replace with clean engine
oi!. (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,
o 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 itto give
protection from dust and dirt.
Cover your unit with a suitable protective cover that
does net 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.
