Although this machine is equipped with mirrors and cameras to ensure good visibility, there are places that can-
not be seen from the operator's seat. Be careful when performing operation.
When driving the machine or performing operations in places with poor visibility, it is dangerous and may cause
serious personal injury or death because it is difficult to check for obstacles and condition of the jobsite. When
driving the machine or performing operations in places with poor visibility, always observe the following.
• Allocate a signalman for jobsite duty if there are areas where the visibility is poor.
• Only one signalman should give signals.
• When working in dark places, turn on the working lamp and headlamps installed to the machine, and set up
additional lighting in the work area if necessary.
• Stop operations if the visibility is poor because of mist, snow, rain, or dust.
• When checking the mirrors installed to the machine, remove all dirt and adjust the angle of the mirror to
ensure good visibility.
• Clean off any dirt from the lens of cameras installed to the machine, and make sure that the camera gives a
clear view.
