GENERAL PRECAUTIONS FOR SAFETY ATTACHMENTS AND OPTIONS
6-6
PRECAUTIONS WHEN USING 6
When long or heavy work equipment is installed, remember the following precautions. Before starting operations,
move the machine to a safe place and carry out a test operation to make sure that you fully understand the move-
ment, center of gravity, and working range of the machine.
q Do not swing the work equipment if the machine is at an angle. If the work equipment is swung with the
machine at an angle, there is danger that the machine will tip over.
q Always maintain a safe distance from obstacles in the surrounding area when operating. If long work equip-
ment is installed, the working range becomes larger.
q If heavy work equipment is installed, pay careful attention to the following precautions.
q The swing overrun (the distance the work equipment moves before completely stopping after the swing
brake is applied) will be greater. There is danger of hitting objects if the swing overrun is miscalculated, so
allow extra space to the swing position when swinging.
q The hydraulic drift of the work equipment (the amount of the work equipment moves down under its own
weight when it is stopped in a raised position) also becomes greater. Do not stop the work equipment in a
raised position; always lower it to the ground.
q Do not swing, lower, or stop the work equipment suddenly. There is danger that the machine may tip over.
q Do not suddenly extend or retract the boom cylinder. The shock may cause the machine to tip over.
