General Safety & Operation

A3-9

Truck Operation - General

  • Wear seat belts at all times. 

  • Only authorized persons are allowed to ride in

the truck. Passengers must be in the cab and

belted in the passenger seat.

  • DO NOT allow anyone to ride on the decks or on

the steps of the truck.

  • DO NOT allow anyone to get on or off the truck

while it is in motion.

  • DO NOT move the truck in or out of a building

without a signal person present.

  • Know and obey hand signal communications

between the operator and spotter. When other

machines and personnel are present, the

operator must move in and out of buildings,

loading areas, and through traffic, under the

direction of a signal person. Courtesy at all times

is a safety precaution!

  • Immediately report any adverse conditions on the

haul road, pit, or dump area that may cause an

operating hazard.

  • Check for flat tires periodically during a shift. If

the truck has been operating on a flat, DO NOT

park indoors until the tire cools. If the tire must be

changed, DO NOT stand in front of the rim and

locking ring when inflating a tire mounted on the

machine. Observers must not be permitted in the

area and must be kept away from the side of

such tires.

The tire and rim assembly may explode if sub-
jected to excessive heat. Personnel must move to
a remote or protected location if there is a fire near
the tire and wheel area, or if the smell of burning
rubber or excessively hot brakes is evident.

If the truck must be approached, such as to fight
a fire, those personnel must do so only while fac-
ing the tread area of the tire (front or back),
unless protected by the use of large heavy equip-
ment as a shield. Stay at least 15 m (50 ft) from
the tread of the tire.

In the event of fire in the tire and wheel area
(including brake fires), stay away from the truck
for at least eight hours, or until the tire and wheel
are cool.

  • Keep serviceable, fire fighting equipment nearby.

Report used extinguishers for replacement or

refilling.

  • Apply the parking brake when the truck is parked

and unattended. DO NOT leave the truck

unattended while the engine is on.

  • Park the truck a safe distance away from other

vehicles, as determined by the supervisor.

  • Stay alert at all times! In the event of an

emergency, be prepared to react quickly and

avoid accidents. If an emergency arises, know

where to get prompt assistance.

Traveling In The Truck

  • When traveling on rough ground, travel at low

speeds. When changing direction, avoid turning

suddenly.

  • Lower the dump body, and set the dump lever to

the FLOAT position before traveling.

  • If the engine stops while the truck is in motion,

the steering and brakes will continue to operate,

but only for a fixed amount of oil consumption.

Steer immediately to a safe spot, and stop the

truck. When the truck is completely stopped,

apply the parking brake.

Precautions When Traveling In Reverse

Before operating the
machine or work equip-
ment, do as follows:

  • Ensure the back-up alarm works properly.

  • Sound the horn to warn people in the area. 

  • Check for personnel near the machine. Do a

thorough check behind the machine.

  • When necessary, designate a person to watch

the area for the truck operator. This is particularly

necessary when traveling in reverse.

  • When operating in hazardous areas and areas

with poor visibility, designate a person to direct

work site traffic.

  • DO NOT allow anyone to enter the line of travel

of the machine. This rule must be strictly obeyed,

even with machines equipped with a back-up

alarm or rearview mirror.
