PRECAUTIONS FOR USING
Keep the following precautions in your mind when long or heavy work equipment is installed. Before starting
operations, move the machine to a safe place and perform a test operation to make sure that you fully under-
stand the movement, center of gravity, and working range of the machine.
• Do not perform the swing operation if the machine is at an angle. If the swing is performed with the machine
at an angle, there is a danger that the machine may tip over.
• Always allow extra space to the position you want to stop swinging when performing the swing.
If long work equipment is installed, the working range becomes larger. So be more careful to maintain a
safe distance from the surroundings.
• If heavy work equipment is installed, pay attention to the following precautions.
• The swing overrun (the distance the work equipment moves before completely stopping after the swing
brake is applied) will be greater. It is dangerous if a lifted load hits any person or structure. Always
maintain a safe distance to the swing stop position when operating.
• 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 equip-
ment in air.
• Do not suddenly swing, lower, or stop the work equipment. It is dangerous that the machine may tip
over.
• Do not suddenly extend or retract the boom cylinder rod. The shocks may cause the machine to tip
over.
