General Safety & Operation

A03048

Traveling On Slopes

  • Traveling on slopes could result in the machine

tipping over or slipping.

  • DO NOT change direction on the slopes. To

ensure safety, drive to level ground before

turning.

  • DO NOT travel up and down on grass, fallen

leaves, or wet steel plates. These materials may

cause the machine to slip on even the slightest

slope. Avoid traveling sideways, and keep travel

speed low.

  • When  traveling  downhill, use the retarder to

reduce speed. DO NOT turn the steering wheel

suddenly. DO NOT use the foot brake, except in

an emergency.

  • If the engine stops on a slope, apply the service

brakes fully and stop the machine. Apply the

parking brake after the machine has stopped.

Ensuring Good Visibility

  • When working in dark places, install work lamps

and headlamps.

  • Safely stop the truck if visibility is poor, such as in

mist, snow, or rain. Wait for the weather to

improve to allow safe travel.

Operating On Snow

  • When working on snowy or icy roads, there is

danger that the machine may slip on even the

slightest slope. Travel slowly and avoid sudden

starting, turning, or stopping in these conditions.

  • Use caution when clearing snow. The road

shoulder and other objects may be buried in the

snow and cannot be seen.

Avoid Damage To The Dump Body

  • When working in tunnels, on bridges, under

electric cables, or when entering an enclosed

area where there are height limits, use extreme

caution. The dump body must be completely

lowered before driving.

Driving with a raised dump body, or raising the
dump body in an enclosed area, may result in
serious damage and bodily injury or death. Drive
with the dump body resting on the frame.

Driving Near High-Voltage Cables

  • Driving near high-voltage cables can cause

electric shock. Maintain the safe distances

between the machine and the electric cable, as

listed below.        

The following actions are effective in preventing acci-
dents while working near high voltages:

  • Wear shoes with rubber or leather soles.

  • Use a signalman to give warning if the machine

approaches an electric cable.

  • If the work equipment must touch an electric

cable, the operator must remain in the cab.

  • When working near high-voltage cables, DO

NOT allow anyone to approach the machine.

• Check with the electrical maintenance

department about the voltage of the cables

before operating the truck.

When Loading The Truck

  • Ensure the surrounding area is safe. If so, stop

the machine in the correct loading position and

evenly load the body.

  • DO NOT leave the operator's seat during loading.

When Dumping

  • Before starting, check that there is no person or

objects behind the machine.

  • Stop the machine in the desired location. Check

again for persons or objects behind the machine.

Give the determined signal, then slowly operate

the dump body. If necessary, use blocks for the

wheels or position a flagman.

  • When dumping on slopes, machine stability is

poor and there is danger of tip over. Avoid

dumping on slopes whenever possible.

  • DO NOT travel with the dump body raised.
