SafeHandling 0f Gas01ine:

To avoid personal injury or property damage use extreme care
in handling gasoline. Gasoline is extremely flammable and the
vapors are explosive. Serious personal injury can occur when

gasoline is spilled on yourself or your clothes which can ignite.
Wash your skin and change clothes immediately.

Thoroughly inspect the area where the equipment is to
be used. Remove all stones, sticks, wire, and other foreign
objects which could be tripped over and cause personal

a. Use only an approved gasoline container.
b. Never fill containers inside a vehicle or on a truck

or trailer bed with a plastic liner. Always place
containers on the ground away from your vehicle

before filling.

When practical, remove gas-powered equipment
from the truck or trailer and refuel it on the ground.
If this is not possible, then refuel such equipment on

a trailer with a portable container, rather than from a
gasoline dispenser nozzle.

d_

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.

e_

Extinguish all cigarettes, cigars, pipes and other
sources of ignition.

Never fuel machine indoors.

g.

Never remove gas cap or add fuel while the engine
is hot or running. Allow engine to cool at least two

minutes before refueling.
