I. GENERAL OPERATION
• Read, understand, and follow all
instructions on the machine and in the
manual before starting.
• Do not put hands or feet near rotating
parts or under the machine. Keep clear
of the discharge opening at all times.
• Only allow responsible adults, who are
familiar with the instructions, to operate
the machine.
• Clear the area of objects such as
rocks, toys, wire, etc., which could be
picked up and thrown by the blades.
• Be sure the area is clear of bystand-
ers before operating. Stop machine if
anyone enters the area.
• Never carry passengers.
• Do not mow in reverse unless abso-
lutely necessary. Always look down
and behind before and while backing.
• Never direct discharged material
toward anyone. Avoid discharging
material against a wall or obstruction.
Material may ricochet back toward the
operator. Stop the blades when crossing gravel surfaces.
• Do not operate machine without the
entire grass catcher, discharge guard,
or other safety devices in place and
working.
• Slow down before turning.
• Never leave a running machine
unattended. Always turn off blades,
set parking brake, stop engine, and
remove keys before dismounting.
• Disengage blades when not mowing.
Shut off engine and wait for all parts to
come to a complete stop before cleaning the machine, removing the grass
catcher, or unclogging the discharge
guard.
• Operate machine only in daylight or
good artifi cial light.
• Do not operate the machine while
under the infl uence of alcohol or drugs.
• Watch for traffi c when operating near
or crossing roadways.
• Use extra care when loading or unloading the machine into a trailer or truck.
• Always wear eye protection when operating machine.
• Data indicates that operators, age 60
years and above, are involved in a
large percentage of riding mower-related injuries. These operators should
evaluate their ability to operate the
riding mower safely enough to protect
themselves and others from serious
injury.
• Follow the manufacturer’s recommendation for wheel weights or counterweights.
• Keep machine free of grass , leaves
or other debris build-up which can
touch hot exhaust / engine parts and
burn. Do not allow the mower to plow
leaves or other debris which can cause
build-up to occur. Clean any oil or fuel
spillage before operating or storing the
machine. Allow machine to cool before
storage.

SAFETY RULES
II. SLOPE OPERATION
Slopes are a major factor related to loss of
control and tip-over accidents, which can
result in severe injury or death. Operation on all slopes requires extra caution. If
you cannot back up the slope or if you feel
uneasy on it, do not mow it.
• Mow up and down slopes, not across.
• Watch for holes, ruts, bumps, rocks, or
other hidden objects. Uneven terrain
could overturn the machine. Tall grass
can hide obstacles.
• Choose a low ground speed so that
you will not have to stop or shift while
on the slope.
• Do not mow on wet grass. Tires may
lose traction.
Always keep the machine in gear when
going down slopes. Do not shift to
neutral and coast downhill.
• Avoid starting, stopping, or turning on
a slope. If the tires lose traction, disengage the blades and proceed slowly
straight down the slope.
• Keep all movement on the slopes slow
and gradual. Do not make sudden
changes in speed or direction, which
could cause the machine to roll over.
• Use extra care while operating machine with grass catchers or other attachments; they can affect the stability
of the machine. Do no use on steep
slopes.
• Do not try to stabilize the machine by
putting your foot on the ground.
• Do not mow near drop-offs, ditches,
or embankments. The machine could
suddenly roll over if a wheel is over the
edge or if the edge caves in.
III. 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 the watchful care of a responsible adult other than the operator.
• Be alert and turn machine off if a child
enters the area.
• Before and while backing, look behind
and down for small children.
• Never carry children, even with the
blades shut off. They may fall off and
be seriously injured or interfere with
safe machine operation. Children who
have been given rides in the past may
suddenly appear in the mowing area
for another ride and be run over or
backed over by the machine.
• Never allow children to operate the
machine.
• Use extra care when approaching blind
corners, shrubs, trees, or other objects
that may block your view of a child.
IV. TOWING
• Tow only with a machine that has a
hitch designed for towing. Do not attach towed equipment except at the
hitch point.
• Follow the manufacturer’s recommendation for weight limits for towed
equipment and towing on slopes.
• Never allow children or others in or on
towed equipment.
• On slopes, the weight of the towed
equipment may cause loss of traction
and loss of control.
• Travel slowly and allow extra distance
to stop.
V. SERVICE
SAFE HANDLING OF GASOLINE
To avoid personal injury or property
damage, use extreme care in handling
gasoline. Gasoline is extremely fl ammable
and the vapors are explosive.
• Extinguish all cigarettes, cigars, pipes,
and other sources of ignition.
• Use only approved gasoline container.
• Never remove gas cap or add fuel with
the engine running. Allow engine to
cool before refueling.
• Never fuel the machine indoors.
• Never store the machine or fuel container where there is an open fl ame,
spark, or pilot light such as on a water
heater or other appliances.
• Never fi ll containers inside a vehicle
or on a truck or trailer bed with plastic
liner. Always place containers on the
ground away from your vehicle when
fi lling.
3
SAFETY RULES
• Remove gas-powered equipment from
the truck or trailer and refuel it on the
ground. If this is not possible, then
refuel such equipment with a portable
container, rather than from a gasoline
dispenser nozzle.
• Keep the nozzle in contact with the rim
of the fuel tank or container opening at
all times until fueling is complete. Do
not use a nozzle lock-open device.
• If fuel is spilled on clothing, change
clothing immediately.
• Never overfi ll fuel tank. Replace gas
cap and tighten securely.
GENERAL SERVICE
• Never operate machine in a closed
area.
• Keep all nuts and bolts tight to be sure
the equipment is in safe working condition.
• Never tamper with safety devices.
Check their proper operation regularly.
• Keep machine free of grass, leaves, or
other debris build-up. Clean oil or fuel
spillage and remove any fuel-soaked
debris. Allow machine to cool before
storing.
• If you strike a foreign object, stop and
inspect the machine. Repair, if necessary, before restarting.
• Never make any adjustments or repairs
with the engine running.
• Check grass catcher components and
the discharge guard frequently and
replace with manufacturer’s recommended parts, when necessary.
• Mower blades are sharp. Wrap the
blade or wear gloves, and use extra
caution when servicing them.
• Check brake operation frequently. Adjust and service as required.
• Maintain or replace safety and instruction labels, as necessary.
• Be sure the area is clear of bystanders before operating. Stop machine if
anyone enters the area.
• Never carry passengers.
• Do not mow in reverse unless absolutely necessary. Always look down
and behind before and while backing.
• Never carry children, even with the
blades shut off. They may fall off and
be seriously injured or interfere with
safe machine operation. Children who
have been given rides in the past may
suddenly appear in the mowing area
for another ride and be run over or
backed over by the machine.
• Keep children out of the mowing area
and in the watchful care of a responsible adult other than the operator.
• Be alert and turn machine off if a child
enters the area.
• Before and while backing, look behind
and down for small children.
• Mow up and down slopes (15° Max),
not across.
• Choose a low ground speed so that
you will not have to stop or shift while
on the slope.
• Avoid starting, stopping, or turning on
a slope. If the tires lose traction, disengage the blades and proceed slowly
straight down the slope.
• If machine stops while going uphill,
disengage blades, shift into reverse
and back down slowly.
• Do not turn on slopes unless necessary, and then, turn slowly and gradually downhill, if possible.
