q
ing equipment. There is danger that the load may spill or the bucket may hit the dump truck and cause serious
personal injury or death.
Generally speaking, the machine is more liable to overturn when the work equipment is at the side than when it
q
is at the front or rear.
Be extremely careful when swinging the work equipment from the front or rear to the side of machine while it is
applied a load. There is danger that the machine may turn over.

q
turning over. When operating on flat ground as well as on slopes, observe the following.
• Do not suddenly lower, swing, or stop the work equipment.
• Do not suddenly extend or retract the boom cylinder. There is a hazard that impact will cause the machine to
turn over.
In the operation using the fork or grapple, do not attempt to pick
q
up an object with their tips. There is a danger of damage to the
