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. i ii, ii ....
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.

control bar is released. To stop forward motion without
stopping engine, release the operator presence control
bar slightly untif 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,

BEFORE STARTING ENGINE OIL (See Fig, 6)
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 wtdipstick and fill to the full line on
the dipstick..
- Use 20 ozsoof oil. For type and grade of oil to use, see
ENGINE in Customer Responsibilities section of this
manual
FIG, 3 7

OPERATION
•Pour oil slowly Do not over fill.
•Check oil level before each use. Add oil ifneeded. Fili to
full line ot_dipstick
o To read proper _evel,tighten engine oil cap each time.
•Reinstall engine oil cap and tighten,
.After the first two (2) hours ofmowing, change the oil, and
every 25 hours thereafter You may need to change the
oil more often under dusty, dirty conditions
GAS (See Fig. 6)
•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 ionger_ 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
. To start a cold engine, push primerfive (5) times before
trying to start. Use a firm push This step isnot usually
necessary when starting an engine which has already
run for a few minutes.
• 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 cooker weather it may be necessary to repeat
priming steps. In warmer weather over priming maycause
flooding and engine wiil not start. If you do flood engine,
wait a few minutes before attempting to start and DO NOT
repeat priming steps.

= For extremely heavy cutting, reduce the width of cut by
overlapping previously cut path and mow slowly,,
• For better grass bagging and most cutting conditio#s,
the engine speed should be set in the 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 in cloth 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,
oKeep top of engine around starter clear and clean of
grass clippings and chaff. This will help engine airflow
and extend engine life.
MULCHING MOWING TBPS
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 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 recutting action of the
blades.
,Avoid cutting your lawn when it,is wet. Wet grass tends
to form clumps and interferes with the mulching action,
The best time to mow your tawnis the early afternoon,
At this time the grass has dried and the newly cut area
will not be exposed to the direct sun.
o For best results, adjust the lawn mower cutting height
so that the lawn mower cuts off only the top one4hird
of the grass blades (See Fig.. 7). 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 by
overlapping previously cut path and mow slowly.
o 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.
FIG. 6
MOWING TIPS
. Under certain 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.

wheel Do not attempt to sharpen while on the mower
• To check blade baiance, drive a nail into a beam orwall.
Leave about one inch of the straight nait 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.

The wheels not turning freely means trash, grass cuttings,
etc. are in the drive wheel area and must be cleaned to free
drive wheels_
tf necessary to clean the drive wheels, check both front
wheels.
o Remove hubcaps, hairpin cotters and washers,
, Remove wheels from wheel adiusters_
• Remove any trash or grass cuttings from inside the
dust cover, pinion andtor drive wheel gear teeth.

ENGINE
LUBRICATION
Use only high quality detergent oi] rated with API service
classification SF or SG. Select the oil sSAE viscosity grade
according to your expected operating temperature.
=F -20' 0' gO= 32" 40' 80° 60' 188°
°c .3o. -_o= -lo°o° _'o° 20= 30" 4o__L
TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
NOTE: Although multi-viscosity oits (5W30, t0W30 etc.)
improve starting in cold weather, these multi-viscosity oils
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,,
TO CHANGE ENGINE OIL (See Fig,,9)
NOTE: Before tipping lawn mower to drain oil, drain fuel
tank by running engine until fuel tank is empty.
•Disconnect spark p(ug wire from spark plug and place
wire where it cannot come in contact with spark plug.
. Remove engine oil cap; lay aside on a clean surface.
= Tip lawn mower on its side and drain oil into a suitable
container: Rock lawn mower back and forth to remove
any oil trapped inside of engine.
. Wipe off any spilled oit on lawn mower and on side of
engine.
° Fill engine with oil. Fili only to the "FULL" line on the
dipstick. DO NOT OVER FILLo
. Replace engine oil cap.

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
o Drain the fuel tank.
o Start the engine and tet 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.

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 ifusing fuel stabilizer.
