•Do not put hands or feet near or under
rotating parts. Keep clear of the
discharge opening at all times.
• Only allow responsible individuals, who
are familiar with the instructions, to
operate the machine.
• Clear the area of objects such as rocks,
toys, wire, bones, sticks, etc., which
could be picked up and thrown by the
blade.
• Be sure the area is clear of other
people before mowing. Stop machine if
anyone enters the area.
• Do not operate the mower when
barefoot or wearing open sandals.
Always wear substantial foot wear.
• Do not pull mower backwards unless
absolutely necessary. Always look
down and behind before and while
moving backwards.
• Do not operate the mower without
proper guards, plates, grass catcher or
other safety protective devices in place.
• See manufacturer's instructions for
proper operation and installation of
accessories. Only use accessories
approved by the manufacturer.

nism or drive clutch on mowers so
equipped before starting the engine
(motor).
• If the equipment should start to vibrate
abnormally, stop the engine (motor)
and check immediately for the cause.
Vibration is generally awarning of
trouble.
•Always wear safety goggles or safety
glasses with side shields when operat-
ing mower.
II. SLOPE OPERATION
Slopes are a major factor related to slip
and fall accidents which can result in
severe injury.All slopes require extra
caution. If you feel uneasy on a slope, do
not mow it.
DO:
• Mow across the face of slopes: never
up and down. Exercise extreme caution
when changing direction on slopes,
• Remove obstacles such as rocks, tree
limbs, etc.
• Watch for holes, ruts, or bumps. Tall
grass can hide obstacles.
DO NOT:
•Do not trim near drop-offs, ditches or
embankments. The operator could lose
footing or balance.
• Do not trim excessively steep slopes.
•Do not mow on wet grass. Reduced
footing could cause slipping.
II1. CHILDREN
Tragic accidents can occur if the operator
is not alert to the presence of children.
Children are often attracted to the
machine and the mowing activity. Never
assume that children will remain where
you last saw them.
• Keep children out of the trimming area
and under the watchful care of another
responsible adult.
• Be alert and turn machine off if children
enter the area.
• Before and while walking backwards,
look behind and down for small
children.
• Never allow children to operate the
machine.
• Use extra care when approaching blind
corners, shrubs, trees, or other objects
that may obscure vision.

- Never store the machine or fuel
container inside where there is an
open flame, such as awater heater.
• Never run a machine inside a closed
area.
• Never make adjustments or repairs with
the engine (motor) running. Disconnect
the spark plug wire, and keep the wire
away from the plug to prevent acciden-
tal starting.
• Keep nuts and bolts, especially blade
attachment bolts, tight and keep
equipment in good condition.

strike an object. Repair, if necessary,
before restarting.
• Never attempt to make wheel height
adjustments while the engine (motor) is
running.
• Grass catcher components are subject
to wear, damage, and deterioration,
which could expose moving parts or
allow objects to be thrown. Frequently
check components and replace with
manufacturer's recommended parts,
when necessary.
• Mower blades are sharp and can cut.
Wrap the blade(s) or wear gloves, and
use extra caution when servicing them.
• Do not change the engine governor
setting or overspeed the engine.

MOWINGTIPS
•Under certain condttlons, such as very tall
grass, it may be necessary to raise the
height of cut to reduce pushing effed 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, reducethe
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.
• Pores in cloth grass catchers can become
filled with dirt and dust with use and
catchers wilt cotlecl less grass. To prevent
this, regulady 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 wil_help engine air flow end extend
engine life.

with API service classification SF, SH or
SG. Select the oil's SAE viscosity grade
according to your expected operating
.t
NOTE: Although multi-viscosity oils
(5W30, lOW30 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 every 25 hours of
operation 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.

FUELSYSTEM
IMPORTANT:Itisimportanttoprevent
_uUmdeposits from forming in essential
el 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
alternative in minimizing the formation of
fuel gum deposits during storage. Add
stabilizer to gasoline in fuet 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.
ENGINE OIL
Drain oil (with engine warm) and replace
with clean engine oil. (See "ENGINE" in
the Maintenance section of this manual).
CYLINDER
Remove spark plug.
Pour one ounce (29 ml) of oil through
sparkplug holeintocylinder.
Pullstarterhandle slowlya few timesto
distribute oil.
• Replace with new spark plug.
OTHER
• Do not store gasoline from one season
to another.
• 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 protec-
tive cover that does not retain moisture.
Do not use plastic. Plastic cannot
breathe which allows condensation to
form and will cause your unit to rust.
IMPORTANT: Never cover mower while
engine and exhaust areas are still warm,
ACAUTION: Never store the lawn mower
with gasoline in the tank inside a building
where fumes may reach an open flame or
spark. Allow the engine to cool before
storing in any enclosure.
