ENGINE SPEED
The engine speed was set at the factory
for optimum performance, Speed is not
adjustable.
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 control° The blade
turns when the engine is running,
° Your lawn mower is equipped with an
operator presence 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
° Raise wheels for low cut and lower
wheels for high cut.
° Adjust cutting height to suit your
requirements.
Medium position is best
for most lawns.
• To change cutting height, squeeze
adjuster lever toward wheel. Move
wheel up or down to suit your requirements. Be sure all wheels are in the
same setting.
CAUTION:
Do not run your lawn mower
without discharge guard, approved grass
catcher in place.
BEFORE STARTING ENGINE
OIL
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 plug and fill to the
top of slot in filler hole.
° Use 20 ozs. of oil. For type and grade
of oil to use, see "ENGINE" in Customer
Responsibilities section of this manual.
o Pour oil slowly. Do not over fill.
o Check oil level before each use. Add oil
if needed.
o Reinstall engine oil plug and tighten.
o Change the oil after every 25 hours of
operation or each season. You may
need to change the oil more often under
dusty, dirty conditions.
GAS
°
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.
Gasoline filler cap

NOTE: Adjuster is properly positioned
when plate tab inserts between tabs in

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_
Hold operator presence control bar
down to the handle and pull starter
handle quickly. DO NOT allow starter
rope to snap back.
o To STOP engine, release operator
presence control bar.

NOTE: Incoolerweatherit may
be
necessary to repeat priming steps_ In
warmer weather over priming may cause
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
o 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.
• 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.
7
o For better grass bagging and most
cutting conditions, the engine speed
should be set in the fast position
o 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,
° Keep top of engine around starter clear
and clean of grass clippings and chaff,
This will help engine air flow and extend
engine life.

FUEL SYSTEM
Drain oil (with engine warm) and replace with
clean engine oil (See "ENGINE" in the
Customer Responsibilities section of this
manual).
CYLINDER
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
o Drain the fuel tank.
o Start the engine and let it run until the fuel
lines and carburetor are empty.
o Never use engine or carburetor cleaner
products in the fuel tank or permanent
damage may occur
,, Use fresh fuel next season
NOTE: Fuel stabilizer is an acceptable
alternative in minimizing the formation of fuel
gum deposits during storage. 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,
