BEFORE STARTING
The operation of any lawn mower can result in
foreign objects thrown into the eyes, which can
result in severe eye damage. Always wear
safety glasses or eye shields while operating
your lawn mower or performing any adjustments or repairs. We recommend a wide
vision safety mask over spectacles or standard
safety glasses.
HOW TO USE YOUR LAWN MOWER
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 and fill to the full
line on the dipstick.
• Use 20 ozs. of oil. For type and grade
of oil to use, see "ENGINE" in Maintenance section of this manual.
ENGINE SPEED
The engine speed was sat at the factory for
optimum performance. Speed is not adjustable.
ENGINE
ZONE
CONTROL
• Pour oil slowly. Do not over fill.
• 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.
• 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.

:
ACAUTION:
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
= 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.
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 fuel tank, start the
engine and let it run until 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 fuel tank
or permanent damage may occur.

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 will not start. If you do
flood engine wait a few minutes before
attempting to start and DO NOT repeat
priming steps.
MOWING
TIPS
• Under certain conditions, such as very
tal} 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.

CLEANING
IMPORTANT: For best performance, keep
mower housing free of built-up grass and
trash. Clean the underside of your mower after
each use.
ACAUTION:
Disconnect spark plug wire from
spark plug and place wire where it cannot

• Turn lawn mower on its side. Make sure air
filter and carburetor are up. Clean the
underside of your lawn mower by scraping
to remove build-up of grass and trash.
• Clean engine often to keep trash from
accumulating. A clogged engine runs hotter
and shortens engine life.
• Keep finished surfaces and wheels free of
all gasoline, oil,etc.
• We do not recommend using a garden
hose to clean lawn mower unless the
electrical system, muffler, air filter and
carburetor are covered to keep water out.
Water in engine can result in shortened
engine life.
Change your spark plug each year to make
your engine start easier and run better. Set
spark plug gap at .030 inch.
ACAUTION:
BEFORE PERFORMINGANY
SERVICE OR ADJUSTMENTS:
• Release control bar and stop engine..
• Make sure the blade and all moving parts
have completely stopped.

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.
