• To prepare for any possible emergencies, wear rubber shoes and gloves. Lay a rubber sheet on the opera-
tor's seat, and be careful not to touch the chassis with any exposed part of your body.
• Use a signalman to give warning if the machine approaches too close to the electric cables.
• When performing operations near high voltage cables, prohibit anyone other than related persons to come
close to the machine during operation.
• If the machine should come too close or touch the electric cable, to prevent electric shock, the operator
should not leave the operator's compartment until it has been confirmed that the electricity has been shut
off. Also, prohibit any other persons to come close to the machine.
ENSURE GOOD VISIBILITY
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.
• When cleaning the camera, wipe off any dirt with soft cloth. Make sure that a clear view is displayed on the
monitor.
When cleaning camera, if you stand on an unstable place, or take an unstable posture, you may fall and be
injured. Put proper stepladder or step on the level and firm ground, and clean the camera in secure posture.
CHECK SIGNS AND SIGNALMAN'S SIGNALS
If signals and labels are not clear, serious personal injury can result from downward slip, overturn or accidental
contact with nearby people or obstacles. Always observe the following.
• Set up labels to inform of road edges and soft ground. If the visibility is not good, position a conductor if
necessary. Operator should pay careful attention to the labels and follow the instructions from the conduc-
tor.
• Only one signalman should give signals.
• Make sure that all workers understand the meaning of all signals, signs, and labels before starting work.
