POTENTIAL HAZARD
♦ In certain conditions gasoline is extremely flammable
and highly explosive.

HOW TO AVOID THE HAZARD
♦ Purchase and store gasoline only in an approved
container.

from your vehicle before f illing.
♦ Do not fill gasoline containers inside a vehicle or on a
truck or trailer bed because interior car pet s or plastic
truck bed liners may insulate the container and slow
the loss of any static charge.
♦ When practical, r emove gas-powered equipment from
the truck or trailer and r efuel 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 the rim of the fuel tank or
container opening at all times until fueling is complete.
DANGER
1.4 OPERATION
Although hazard control and accident prevention are partially dependent upon the
design and configuration of the equipment, t hese factors are also dependent upon
the awareness, concern, prudence, and proper training of t he personnel i nvol ved in
the operation, transport, maintenance, and st orage of t he equi pment . It is essential
that all Operator Safety Mechanisms be connect ed and i n operat i ng condi t ion prior
to use for mowing.
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 proper t y
damage, personal injury, and/or deat h.
HOW TO AVOID THE HAZARD
♦ Provide adequate ventilation of any enclosed trailer to
prevent build up of gasoline vapors, especially at floor
level.
♦ Refuel only outdoors, never inside an enclosed trailer.
♦ Be sure all fuel tanks and gasoline st or age containers
have proper caps installed to prevent spillage and
minimize vapor escaping into the trailer.
♦ Do not place any equipment that is leaking gasoline in
an enclosed trailer.
WARNING

• See inside the back cover to determine the approximate slope angle of the area
to be mowed.
• Progressively greater care is needed as the slope increases.
• Always avoid sudden starting or stopping on a slope. If tir es lose t r action,
disengage the blades and proceed slowly off the slope.
• 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.
• Remove or mark obstacles such as rocks, t ree limbs, etc. from the m owing area.
Tall grass can hide obstacles.
