equipment is to be used and remove all stones,
sticks, wires, bones, and other foreign objects
which may damage the equipment or cause personal
injury to operator or bystanders.

Do not operate without entire exhaust
system in place and in proper working
condition.

POTENTIAL HAZARD
 In certain conditions gasoline is

extremely flammable and highly
explosive.

WHAT CAN HAPPEN
 A static charge can ignite gasoline

vapors. A fire or explosion from
gasoline can burn you, others, and
cause property damage.

HOW TO AVOID THE HAZARD
 Purchase and store gasoline only in an

approved container.

 Always place gasoline containers on

the ground away from your vehicle
while filling.

 Do not fill gasoline containers inside a

vehicle or on a truck or trailer bed
because interior carpets or plastic truck
bed liners may insulate the container
and slow the loss of any static charge.

 When practical, remove gas-powered

equipment from the truck or trailer and
refuel the equipment with its wheels on
the ground.

 If this is not possible, then refuel such

equipment on a truck or trailer from a
portable container, rather than from a

gasoline dispenser nozzle.
If a gasoline dispenser nozzle must be used,
keep the nozzle in contact with rim of the
fuel tank or container opening at all times
until fueling is complete.

POTENTIAL HAZARD
 Gasoline vapor can collect inside

enclosed trailers and may be ignited by

electrical sparks or hot engine/exhaust

components.
WHAT CAN HAPPEN
 Explosion and fire may occur, resulting

in property damage, personal injury,

and/or death.
HOW TO AVOID THE HAZARD
 Provide adequate ventilation of any

enclosed trailer to prevent the build-up

of gasoline vapors, especially at floor

level.
 Refuel only outdoors, never inside an

enclosed trailer.
 Be sure all fuel tanks and gasoline

storage containers have proper caps

installed to prevent spillage and

minimize vapor escaping into the

trailer.
Do not place any equipment that is leaking
gasoline into an enclosed trailer.

POTENTAL HAZARD

 Operating engine parts, especially the

muffler, become extremely hot.
WHAT CAN HAPPEN

 Severe burns can occur on contact.
 Debris, such as leaves, grass, brush,

etc. can catch fire.

HOW TO AVOID THE HAZARD

 Do not operate the machine without

guards, shields, and safety devices in

place and working properly.
Keep hands, feet, hair, jewelry, or clothing
away from rotating parts.

1.4 OPERATION

Although hazard control and accident prevention
partially are dependent upon the design and
configuration of the equipment, these factors are also
dependent upon the awareness, concern, prudence,
and proper training of the personnel involved in the
operation, transport, maintenance, and the storage of
the equipment. It is essential that all Operator Safety
Mechanisms be connected and in operating condition
prior to use for mowing.

 Pay attention to any increase in incline.
 Always avoid sudden starting or stopping on a

slope. If tires lose traction, disengage the blades
and proceed slowly off the slope.

 Avoid sudden starts when mowing uphill. Mower

may tip backwards.

 Be aware that loss of traction may occur going

downhill. Weight transfer to the front wheels may
cause drive wheels to slip and cause loss of
braking and steering.

 Watch for ditches, holes, rocks, dips, and rises

that change the operating angle, as rough terrain
could overturn the machine.

 Use extreme care with grass catchers or

attachments. These can change the stability of the
machine and cause loss of control.

1.4.5 Stop the blades when transporting the mower
to and from the area to be mowed.
