injury, comply with these safety instructions
and always pay attention to the safety
alert symbol, which means CAUTION,

WARNING, or DANGER-"personal safety
instruction." Failure to comply with the
instruction may result in personal injury or

death.

Safe Operating Practices

The following instructions are from ANSI
standard B71.1-2003.

This product is capable of amputating hands and
feet and throwing objects. Always follow all safeUT
instructions to avoid serious injury or death.

General Operation

• Read, understand, and follow all instructions
in the operator's manual and on the machine

before starting.

• Do not place hands or feet near rotating parts
or under the machine. Keep dear of the

discharge opening at all times.

• Allow only 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 blade.

• Be sure the area is dear of other people before
mowing. Stop the machine if anyone enters

the area.

• Never carry passengers.

• Do not mow in reverse unless absolutely
necessar> Akvays look down and behind
before and while bac_ng up.

• Be aware of the mower discharge direction and
do not point it at anyone. Avoid discharging

material against a wall or obstruction. Material
may ricochet back toward the operator. Stop
the blade(s) when crossing gravel surfaces.

• Do not operate the mower without either the
entire grass catcher or the guard in place.

• Be alert, slow down and use caution when
ma_ng turns. Look behind and to the side

before changing directions.

• Never leave a running machine unattended.
Akvays turn off blades, set paring brake, stop
engine, and remove key before dismounting.

• Turn off blades when not mowing. Stop the
engine and wait for all parts to come to a
complete stop before cleaning the machine,
removing the grass catcher or unclogging the

discharge chute.

• Operate the machine 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

Always wear eye protection when operating
the mower.

• 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 abiliu _to operate the
riding mower safely enough to protect
themseDes and others from serious injur>

• Always follow the recommendations for wheel
weights or counterweights.

Slope Operation

Slopes are a major factor related to slip and
fall accidents, which can result in severe injur>
Operation on all slopes requires extra caution. If

you feel uneasy on a slope, do not mow it.

• Watch for ditches, holes, rocks, dips, and rises
that change the operating angle, as rough

terrain could overturn the machine.

• Choose a low ground speed so you will not
have to stop while operating on a slope.

• Do not mow slopes when grass is wet. Slippery
conditions reduce traction and could cause

sliding and loss of control.

• Always keep the machine in gear when going
down slopes. Do not shift to neutral and coast

downhill.

machine from the normal operating position.

Think Safety First

Please carefully read all of the safe_" instructions
and decals in the safety section. Knowing this
information could help you, your famil?; pets or

bystanders avoid injur?

Recommended Gasoline

Use UNLEADED Regular Gasoline suitable
for automotive use (87 pump octane minimum).

Leaded regular gasoline may be used if unleaded
regular is not available.

Important: Never use methanol, gasoline

containing methanol, or gasohol containing
more than 10% ethanol because the fuel

system could be damaged. Do not mix oil
with gasoline.

Mowing on wet grass or steep slopes can
cause sliding and loss of control.

Wheels dropping over edges can cause
rollovers, which may result in serious injury,

death or drowning.

To avoid loss of control and possibility of
rollover:

• Do not mow near drop-offs or near water.

• Do not mow slopes greater than

12.5 degrees.

• Reduce speed and use extreme caution
on slopes.

• Avoid sudden turns or rapid speed
changes.

1

In certain conditions, gasoline is extremely
flammable and highly explosive. A fire or

explosion from gasoline can burn you and
others and can damage property.

• Fill the fuel tank outdoors, in an open
area, when the engine is cold. Wipe up

any gasoline that spills.

• Never fill the fuel tank inside an enclosed
trailer.

Do not fill the fuel tank completely full.
Add gasoline to the fuel tank until the
level is 1/4 to 1/2 inch (6 to 13 mm)

below the bottom of the filler neck. This
empty space in the tank allows gasoline

to expand.
Never smoke when handling gasoline,

and stay away from an open flame or
where gasoline fumes may be ignited by

a spark.
Store gasoline in an approved container

and keep it out of the reach of children.
Never buy more than a 30-day supply of
gasoline.
