OPERATmO
HOW TO USE YOUR LAWN MOWER
ENGINE SPEED CONTROL (See Fig. 5)
The engine speed is controlled by a lever located on the
side of the engine. Fast (_) position is for starting engine,
normal cutting and better grass bagging_ Slow (4_.)
position is for light cutting, trimming and fuel economy.
ENGINE ZONE CONTROL
CAUTION: Federal regulations require
an engine control to be installed on this
lawn mower in order to minimize the
risk of blade contact injury, Do not
under any circumstances attempt to
defeat the function of the operator con-
trol. The blade 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.

° Self-propelling is controlled by holding the operator
presence control bar' down to the handle and pushing
the drive control lever forward until it clicks; then
release the lever.
Forward motion will stop when the operator presence
control bar' is released To stop forward motion without
stopping engine, reieasethe operatorpresence control
bar slightly until the drive control disengages. Hold
operator' presence control bar down to handle to con-
tinue mowing without self-propelling.
•To keep drive control engaged when turning corners,
push down on handle and lift front wheels off ground
while turning lawn mower

oWheels are set in low cut for shipping_ Adjust cutting
height to suit your requiraments_ 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
OIL (See Fig. 9)
Your lawn mower is shipped without oil in the engine.
Be sure mower is level and area around oil fill is clean.
o Remove engine oil cap w/dipstick and fill to the full line
on the dipstick
• Use2Oozs.of oil. Fortypeandgradeofoiltouse,see
"ENGINE" in Customer Responsibilities section of this
manual
Pour 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.
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)
° 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 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.
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 usua y
necessary when starting an engine which has already
run for a few minutes.
o Push engine speed control lever to fast (_,) 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 warmerweather over priming maycause
flooding and engine will not start. Ifyou do flood engine wait
a few minutes before attempting to start and DO NOT
repeat priming steps_

MOWING TRPS
o
o
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.
For better grass bagging and most cutting conditions,
the engine speed should be set inthe 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.
o 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.
oPores incloth grass catchers can become filled with dirt
and dust with use and catchers will collect less grass.
Toprevent this, regularly hose catcher off with water
andlet 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

classification SG Select the oil's SAE viscosity grade
according to your expected operating temperature.
SAE VISCOSITY GRADES
NOTE: Although multi-viscosity oils (5W30, 10W30 etc.)
improve starting in cold weather, these multi-viscosity otis
will result in increased oil 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
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 fue! tank.
