SECTION1: IMPORTANTSAFEOPERATIONPRACTICES
_ib ARNING: This symbol points out important safety instructions which, if not followed, could endangerthe 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 tocause 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 a thrown 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
onthemowerdeckorcontacttheengineexhaust
presentingapotentialfirehazard.
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 feel 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 slow 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.
• We do not recommend the use of pressure
washers or garden hose to clean your unit. They
may cause damage to electric components,
spindles, pulleys, bearings or the engine. The use
of water will result in shortened life and reduce
serviceability.
• Check the blade and engine mounting bolts at
frequent intervals for proper tightness. Also,
visuallyinspectbladefordamage(e.g.,excessive
wear,bent,cracked).Replacewithbladewhich
