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

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.
NOTE: Allow oil to settle down into
engine for accurate reading.
• 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.
• To read proper level, tighten engine oil
plug each time.
• Reinstall engine oil plug and tighten.
• 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.
ADD GASOLINE
• Fill fuel tank. Use fresh, clean, regular
unleaded gasoline with a minimum of
87 octane. (Use of leaded gasoline
will increase carbon and lead oxide
deposits and reduce valve life). Do not
mix oil with gasoline. Purchase fuel in
quantities that can be used within 30
days to assure fuel freshness.
_I,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 storage of 30 days or
longer. Drain the gas tank, start the
engine and let it run until the fuel lines
and carburetor are empty. Use fresh fuel
next season. See Storage Instructions for
additional information. Never use engine
or carburetor cleaner products in the fuel
tank or permanent damage may occur.
_I,CAUTION: Fill to bottom of gas tank
filler neck. Do not overfill. Wipe off any
spilled oil or fuel. Do not store, spill or use
gasoline near an open flame.

TO START ENGINE
• 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.
• To stop engine, release operator presence
control bar.
NOTE: In cooler weather it may be
necessary to repeat priming steps. In
warmer weather over priming may cause
flooding and engine wilt not start. If you
do flood engine, wait a few minutes
before attempting to start and do not
repeat priming steps.
MOWlNGTIPS
• 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. It may also be necessary to
reduce ground speed and/or run the
lawn mower over the area a second
time.
• For extremely heavy cutting, reduce the
width of cut by overlapping previously
cut path and mow slowly.
• For better grass bagging and most
cutting conditions, 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.
•Keep top of engine around starter clear
and clean of grass clippings and chaff.
This will help engine air flow and
extend engine life.

FUELSYSTEM
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: Fuel stabilizer is an acceptable

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.
