PRECAUTIONS FOR OPERATION
SAFETY
2-28
q
To make it easier to escape if there is any problem, set the
tracks at right angles to the road shoulder or cliff with the
sprocket at the rear when carrying out operations.
q
When carrying out demolition work, do not carry out demo-
lition work under the front of the machine. This makes the
ground unstable, and there is a hazard of the machine fall-
ing.
q
When carrying out demolition work, do not carry out demo-
lition work above your head. There is a hazard of broken
parts falling or of the building collapsing and causing seri-
ous injury or death.
q
When carrying out demolition work, do not use the impact
force of the work equipment for breaking work. There is a
hazard of damage to the work equipment and also a haz-
ard of serious personal injury or death being caused by fly-
ing pieces of broken materials, or of the machine tipping
over due to reaction from the impact.
q
The not pass the bucket over the heads of other workers or over the operator's seat of dump trucks or other
hauling equipment. There is danger that the load may spill or the bucket may hit the dump truck and cause
serious personal injury or death.
q
When working on or from the top of buildings or other structures, check the strength and the structure before
starting operations. There is a hazard of the building collapsing and causing serious injury or damage.
q
Generally speaking, the machine is more liable to overturn when the work equipment is at the side than when
it is at the front or rear.
q
When using a breaker or other heavy work equipment, there is a hazard of the machine losing its balance and
tipping over. When operating on flat ground as well as on slopes.
q
Do not suddenly lower, swing, or stop the work equipment.
q
Do not suddenly extend or retract the boom cylinder. There is a hazard that impact will cause the machine
to tip over.
