SECTION1: IMPORTANTSAFEOPERATIONPRACTICES
WARNING: This symbol points out important safety instructions which, if not followed, could
endanger the personal safety and/or property of yourself and others, read and follow all
instructions in this manual before attempting to operate your lawn mower, failure to comply with
these instructions may result in personal injury. When you see this symbol, heed its warning.
WARNING: The Engine Exhaust from this product contains chemicals known to the State of
California to cause cancer, birth defects or other reproductive harm.
DANGER: Your lawn mower was built to be operated according to the rules for safe operation in this
manual. As with any type of power equipment, carelessness or error on the part of the operator can
result in serious injury. This lawn mower is capable of amputating hands and feet and throwing objects.
Failure to observe the following safety instructions could result in serious injury or death.
GENERALOPERATION
• Read, understand, and follow all instructions in the
operator's manual and on the machine before
starting. Keep this manual in a safe place for future
and regular reference and for ordering replacement
parts.
• Only allow responsible individuals familiar with the
instructions to operate the machine. Know controls
and how to stop the machine quickly.
• Do not put hands or feet under cutting deck or near
rotating parts.
• Clear the area of objects such as rocks, toys, wire,
etc., which could be picked up and thrown by the
blade. A small object may have been overlooked
and could be accidentally thrown by the mower in
any direction and cause injury to you or a
bystander. To help avoid athrown objects injury,
keep children, bystanders and helpers at least 75
feet from the mower while it is in operation. Always
wear safety glasses or safety goggles during
operation or while performing an adjustment or
repair, to protect eyes from foreign objects. Stop
the blade(s) when crossing gravel drives, walks or
roads.
• Be sure the area is clear of other people before
mowing. Stop machine if anyone enters the area.
• Never carry passengers.
• Disengage blade(s) before shifting into reverse and
backing up. Always look down and behind before
and while backing.
• Be aware of the mower and attachment discharge
direction and do not point it at anyone. Do not
operate the mower without either the entire grass
catcher or the chute guard in place.
• Slow down before turning. Operate the machine
smoothly. Avoid erratic operation and excessive
speed.
• Never leave a running machine unattended.
Always turn off blade(s), place transmission in
neutral, set park brake, stop engine and remove
key before dismounting.
• Turn off blade(s) when not mowing.
• Stop engine and wait until blade(s) comes to a
complete stop before (a) removing grass catcher or
unclogging chute, or (b) making any repairs,
adjusting or removing any grass or debris.
• Mow only in daylight or good artificial light.
• Do not operate the machine while under the
influence of alcohol or drugs.
• Watch for traffic when operating near or crossing
roadways.
• Use extra care when loading or unloading the
machine into a trailer or truck. This unit should not
be driven up or down a ramp onto a trailer or truck
under power, because the unit could tip over,
causing serious personal injury. The unit must be
pushed manually on a ramp to load or unload
properly.
• Never make a cutting height adjustment while
engine is running if operator must dismount to do
so.
• Wear sturdy, rough-soled work shoes and close-
fitting slacks and shirts. Do not wear loose fitting
clothes or jewelry. They can be caught in moving
parts. Never operate a unit in bare feet, sandals, or
sneakers.
• Check overhead clearance carefully before driving
under power lines, wires, bridges or low hanging
tree branches, before entering or leaving buildings,
or in any other situation where the operator may be
struck or pulled from the unit, which could result in
serious injury.
• Disengage all attachment clutches, thoroughly
depress the brake pedal, and shift into neutral
before attempting to start engine.
• Your mower is designed to cut normal residential
grass of a height no more than 10". Do not attempt
to mow through unusually tall, dry grass (e.g.,
pasture) or piles of dry leaves. Debris may build up
on the mower deck or contact the engine exhaust
presenting a potential fire hazard.
SLOPEOPERATION
Slopes are a major factor related to loss of control and
tip-over accidents which can result in severe injury or
death. All slopes require extra caution. If you cannot
back up the slope or ifyou feet uneasy on it, do not mow
it.
For your safety, use the slope gauge included as part of
this manual to measure slopes before operating this
unit on a sloped or hilly area. If the slope is greater than
15° as shown on the slope gauge, do not operate this
unit on that area or serious injury could result.
DO:
• Mow up and down slopes, not across.
• Remove obstacles such as rocks, limbs, etc.
• Watch for holes, ruts or bumps. Uneven terrain
could overturn the machine. Tall grass can hide
obstacles.
• Use stow speed. Choose a low enough gear so that
you will not have to stop or shift while on the slope.
Always keep machine in gear when going down
slopes to take advantage of engine braking action.
• Follow the manufacturer's recommendations for
wheel weights or counterweights to improve
stability.
• Use extra care with grass catchers or other
attachments. These can change the stability of the
machine.
• Keep all movement on the slopes slow and gradual.
Do not make sudden changes in speed or direction.
Rapid engagement or braking could cause the front
of the machine to lift and rapidly flip over backwards
which could cause serious injury.
• Avoid starting or stopping on a slope. If tires lose
traction, disengage the blade(s) and proceed slowly
straight down the slope.
DONOT:
• Do not turn on slopes unless necessary; then, turn
slowly and gradually downhill, if possible.
• Do not mow near drop-offs, ditches or
embankments. The mower could suddenly turn
over if a wheel is over the edge of a cliff or ditch, or
if an edge caves in.
• Do not mow on wet grass. Reduced traction could
cause sliding.
• Do not try to stabilize the machine by putting your
foot on the ground.
• Do not use grass catcher on steep slopes.
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 mowing area and in
watchful care of an adult other than the operator.
• Be alert and turn machine off if children enter the
area.
• Before and when backing, look behind and down
for small children.
• Never carry children, even with the blades off. They
may fall off and be seriously injured or interfere with
the safe machine operation.
• Never allow children under 14 years old to operate
the machine. Children 14 years and over should
only operate machine under close parental
supervision and proper instruction.
• Use extra care when approaching blind corners,
shrubs, trees or other objects that may obscure
your vision of a child or other hazard.
• Remove key when machine is unattended to
prevent unauthorized operation.
SERVICE
• Use extreme care in handling gasoline and other
fuels. They are extremely flammable and the
vapors are explosive.
• Use only an approved container.
• Never remove fuel cap or add fuel with the engine
running. Allow engine to cool at least two minutes
before refueling.
• Replace fuel cap securely and wipe off any spilled
fuel before starting the engine as it may cause a fire
or explosion.
• Extinguish all cigarettes, cigars, pipes and other
sources of ignition.
• Never refuel the machine indoors because fuel
vapors will accumulate in the area.
• Never store the fuel container or machine inside
where there is an open flame or spark, such as a
gas hot water heater, space heater or furnace.
• Never run a machine inside a closed area.
• To reduce fire hazard, keep the machine free of
grass, leaves or other debris build-up. Clean up oil
or fuel spillage. Allow machine to cool at least 5
minutes before storing.
• Before cleaning, repairing or inspecting, make
certain the blade and all moving parts have
stopped. Disconnect the spark plug wire, and keep
the wire away from the spark plug to prevent
accidental starting.

SECTION11:OFF-SEASONSTORAGE
If the machine is to be inoperative for a period longer
than 30 days, prepare for storage as follows.
• Clean the engine and the entire unit thoroughly.
• Lubricate all lubrication points. Wipe the entire
machine with an oiled rag to protect the surfaces.
• Refer to the engine manual for correct engine
storage instructions. The engine must be
completely drained of fuel and a fuel stabilizer used
to prevent gum deposits from forming on essential
carburetor parts, fuel lines and fuel tanks.
• Charge battery fully. The battery loses some of its
charge each day when the unit is not used. NEVER
store battery without a full charge. Recharge
battery before returning to service or every two
months, whichever occurs first.
• When storing unit for extended periods, disconnect
battery cables. Removing battery from unit is
recommended.
• Store unit in a clean, dry area. Do not store next to
corrosive materials, such as fertilizer.
NOTE: When storing any type of power equipment in
an unventilated or metal storage shed, care should be
taken to rustproof the equipment. Using a light oil or
silicone, coat the equipment, especially any chains,
springs, bearings and cables.

There are two switches in the starting circuit of your unit: the clutch pedal switch and
the deck lift lever switch. Make certain the actuator is fully depressing the buttons on
each switch.
The battery must be installed with negative terminal attached to black ground wire.
Negative terminal is identified at the post by "NEG', "N" or "-". The positive terminal,
identified by "POS', "P" or "+", must be attached to the big red wire which goes to the
solenoid. All batteries are to be fully charged before installing. Refer to "Quick Start"
battery guide that came with the operator's manual.
Check fluid level in battery. If fluid is low, fill to just below split rings with water. Charge
with 6 AMP charger until fully charged.
Refer to operator's manual for fuse box location. Replace fuse with automotive type
fuse. Fuses seldom fail without a reason. The problem must be corrected. Check for
loose connections in the fuse holder. Replace fuse holder if necessary. A dead short
may be in the cranking or charging circuit where the insulation may have rubbed
through and exposed the bare wire. Replace the wire or repair with electrician's tape if
the wire strands have not been damaged.
Note: Look for a wire pinched between body panels, burned by the exhaust pipe or
muffler or rubbed against a moving part.
Engine should have a black ground wire running from engine to frame or mounting
bolt.
Check operator's manual for correct position for throttle control and choke for starting.
Gasoline tank empty. Fill tank.
Fuel line or in-line fuel filter plugged. Remove and clean fuel line. Replace filter if
necessary.
Spark plug lead disconnected. Connect lead. Hold spark plug lead away from engine
block about 1/8". Crank engine. There should be a spark. If not, have engine repaired
at authorized engine service dealer.
Faulty spark plug. To test, remove spark plug. Attach spark plug lead to spark plug.
Ground the spark plug body against the engine block. Crank the engine. The spark
plug should fire at the electrode. Replace if it does not.
If the air cleaner is dirty, the engine may not start. Refer to the engine manual packed
with your unit.
Check oil level.
Dipstick not seated or broken. Replace defective part.
Engine breather defective. Replace.
Stop engine immediately. Check all pulleys, blade adapters, keys and bolts for
tightness and spindle damage. Tighten or replace any damaged parts.
Stop engine immediately. Replace damaged blade. Only use original equipment
blades.
Throttle must be set at full throttle.
Use lower ground speed. The slower your ground speed, the better the quality of cut.
Raise deck.
Sharpen or replace blades (uncut strip problem only).
