WHEN DUMPING
• Before starting the dumping operation, check that there is no person or object behind the machine.
• Stop the machine in the correct position, and check again that there is no person or object 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 carrying out dumping operations on slopes, the machine stability will become poor and there is danger
that it may tip over. Always carry out such operations extremely carefully.
• Do not travel with the dump body raised.
WORKING ON LOOSE GROUND
• Avoid operating the machine too close to the edge of cliffs, overhangs, and deep ditches. If these areas
collapse, the machine could fall or tip over and result in serious injury or death. Remember that the soil after
heavy rain or blasting is weakened in these areas.
• Earth laid on the ground and the soil near ditches is loose. It can collapse under the weight or vibration of the
machine. Avoid these areas, if possible.
WHEN LOADING
• Check that the surrounding area is safe, stop the machine in the correct loading position, then load the body
uniformly.
• Do not leave the operator's seat during the loading operation.
PARKING THE MACHINE
• Choose a horizontal road surface to park the machine. If the machine has to be parked on a slope, always put
blocks under all the wheels to prevent the machine from moving.
• When parking on public roads, provide fences and signs, such as flags or lights, on the machine to warn
pedestrians and other vehicles. Be sure that the machine, flags, or lights do not obstruct the traffic.
• Before leaving the machine, lower the dump body fully, set the parking lever to the PARKING position, stop the
engine, then lock everything. Always take the key with you.
TOWING
WHEN TOWING, FIX WIRE TO HOOK
• Towing in the wrong way may lead to serious personal injury or damage.
• When using another machine to tow this machine, use a towing device with ample strength for the weight of
this machine.
• Never tow a machine on a slope.
• Do not use any towing rope that has kinks or is twisted.
• Do not stand astride the towing cable or wire rope.
• When connecting a machine that is to be towed, do not let any one come between the towing machine and the
machine that is being towed.
• Set the coupling of the machine being towed in a straight line with the towing portion of the machine, and
secure it in position.
(For towing method, see Section A, "Operating Instructions, TOWING".)
