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
instructionscould result in serious injuryor death.
GeneralOperation
• Read, understand, and fol]ow all instructionsinthe
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
instructionsto 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 g]asses or safety goggles during
operation or while performing an adjustment or
repair, to protect eyes from foreign obiects. 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 whi]e 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 whi]e 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 manual]y on a ramp to load or unload
properly.
• Never make a cutting height adjustment whi]e
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 but]dings=
or inany other situation where the operator may be
struck or pulled from the unit=which could result tn
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 tal], dry grass (e.g.,
pasture) or piles of dry leaves. Debris may build up
on the mower deck or centact the engine exhaust
presenting a potential fire hazard.
SlopeOperation
Slopes are a major factor related te less ef centrel and
tip-over accidents which can result in severe injury er
death. All slepes require extra cautien. If yeu cannot
back up the slepe er if yeu feel uneasy en it, de not mow
it.
For yeur safety, use the slepe gauge included as part of
this manual to measure slepes before eperating this
unit ona sloped or hilly area. If the slope isgreater than
"15° as shewn en the slope gauge, de not operate this
unit en that area er serieus injuryceuld result.
Do:
• Mow up and down slopes, net across.
• Remove ebstacles such as recks, limbs, etc.
• Watch for holes, ruts er bumps. Uneven terrain
could overturn the machine. Tall grass can hide
obstacles.
• Use slew speed. Choose a low enough gear so that
you will net 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 countem/eights 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.
De net 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 iniury.
• Avoid starting or stopping on a slope. If tires lose
traction, disengage the blade(s) and proceed slowly
straight down the slope.
DoNet:
• Do not turn on slopes unless necessary; then, turn
slowly and gradually downhill, if possible.
• Do not mow near drop-ells, 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 ifthe operator isnot alert to
the presence of children. Children are often attracted to
the machine and the mowing activity. Never assume
that children will remain where yeu last saw them.
• Keep children out ef the mewing area and in
watchful care of an adult otherthan the eperator.
• Be alert and turn machine eft if children enter the
area.
• Before and when backing, leek behind and dewn
for small children.
• Never carry children, even with the blades eft. They
may fall offand be seriously injured er interfere with
the safe machine operatien.
• Never allow children under 14 years old to operate
the machine. Children 14 years and over should
onlyoperate machine under close parental
supervision and preper instructien.
• Use extra care when appreaching blind cerners,
shrubs, trees or other obiectsthat may obscure
your visien efa child or ether hazard.
• Remove key when machine is unattended te
prevent unauthorized eperation.

• 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 te prevent
accidental starting.
• We do not recemmend the use of pressure
washers er garden hese te clean your unit. They
may cause damage te electric cempenents,
spind]es, pulleys, bearings er the engine. The use
ofwater wt]]result in shertened life and reduce
serviceability.
