1.1 Basic precautions

The dump truck described here is a kind of mining

engineering machinery, which has quite different structure

and working properties compared to ordinary vehicles;

therefore, the safety precautions and operation instructions

involved herein this manual shall be followed prior to the

operation.

1) While working together with other operators or site traffic

commander, make sure that all personnel concerned

understand the hand signals.

2) Always do inspection before or after the operation, so as

to eliminate the potential dangers such as leakage of oil,

water and air, bolt looseness, unusual noise or other hazards

that could cause faults and serious accidents.

3) Never enter or stretch your hands between the moving

components, and avoid any rotating and moving parts. Do

not enter between the cargo body and the frame when the

cargo body is lowering.

4) Always park the truck on a level ground; if you have to

park the truck on a slope, wedge it with cushion blocks. In

this case, please stop the truck with foot brake, set the

transmission control lever to NEUTRAL or REVERSE

position, apply the hand brake, lower down the cargo body,

shut down the engine and remove the key.

5) Do not place the inflammables and explosives near the hot

parts like turbocharger, exhaust pipe, muffler and radiator in

case of fire or other accidents. Before touching the above

parts, make sure that those parts are cooled down to avoid

scald.

change of the truck’s center of gravity.

When driving downhill or uphill with full load:

●Do not make abrupt braking downhill;

●Never disengage the clutch or coast downhill;

●Do not make a sharp turning.

6) When the truck starts running, the cargo body is tiltable;

thus irrelevant personnel wandering around the truck is
