an open flame.

• Fill fuel tank. Use fresh, dean, regular
unleaded gasoline with a minimum of 87
octane. (Useof leaded gasoline
wil
increase carbon and lead oxide deposits
and reduce valve rife). Do not mix on with
gasoline. Purchase fuel in quantities that
can be used within 30 days to assure fuel
freshness.
IMPORTANT: WHEN OPERATING IN
TEMPERATURES BELOW 32°F(0°C), use
fresh, clean winter grade gasoline to help
insure good cold weather starting.
WARNING: Experience indicates that alcohol
b/ended fueis (called gesohoi or using ethanol
or methanol) can attract moisture which leads
to separation and formation of acids during
storage. Acicfic 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.

TO START ENGINE
MOWING
• 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.
• 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 t° reduce
ground speed and/or run the lawn
mower over the area a second time.
TIPS
• 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.
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.
• 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.

(_ Engine oil
The warranty on this lawn mower does not
cover items that have been subjected to
operator abuse or negligence. To receive
full value from the warranty, operator must
maintain mower as instructed in this
manual.
Some adjustments will need to be made
periodically to properly maintain your unit.
All adjustments in the Service and
Adjustments section of this manual should
be checked at least once each season.
(_
• Once a year, replace the spark plug,
clean or replace air filter element and
check blade for wear. A new spark plug
and clean/new air filter element assures
proper air-fuel mixture and helps your
engine run better and last longer.
• Follow the maintenance schedule in this
manual.
BEFORE EACH USE
• Check engine oil level.
• Check for loose fasteners.

REAR DEFLECTOR
The rear deflector, attached between the rear
wheels of your mower, is provided to minimize
the possibilitythat objects will be thrown out of
the rear of the mower into the operator
mowing position. If the deflector becomes
damaged, it should be replaced.

CLEANING
IMPORTANT: For best performance, keep
mower housing free of built-up grass and
trash. Clean the underside of your mower after
each use.
CAUTION: Disconnect spark plug wire from

• 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 de 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.

inthe
Maintenance 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.
• Drain the fuel tank.
• Remove spark plug.
• Pour one ounce (29 ml) of oil through spark
plug hole into cylinder.
• Pull starter handle slowly a few times to
d'_ribute oil.
• Replace with new spark plug.
OTHER
• Do not store gasoline from one season to
another.
• 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.
• Replace your gasoline can if your can starts
to rust. Rust and/or dirt in your gasoline will
cause problems.
• If possible, store your unit indoors and cover
it to give protection from dust and dirt.
• Cover your unit with a suitable protective
