• 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 traveling 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 traveling
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 equipment 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 before
starting the work 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.
• The rear view monitor is provided to secure the rear side visibility. If, however, an obstacle is detected on
the monitor, you must confirm it with your eyes.
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.
BEWARE OF ASBESTOS DUST
Asbestos dust in the air can cause lung cancer if it is inhaled.
There is danger of inhaling asbestos when working on jobsite
where demolition work is performed or industrial waste is han-
dled. Always observe the following.
• Spray water to keep down the dust.
• Do not use compressed air.
• If there is danger that there may be asbestos dust in the
air, always operate the machine from an upwind position,
and make sure that all workers operate on the upwind
side.
• All workers should use anti-dust masks.
• Prohibit other personnel from coming close to the machine during operation.
• Always observe the regulations for jobsite and environmental standards.
This machine does not contain asbestos, but any part which is not the genuine part, it has risk of containing
asbestos. Always use Komatsu genuine parts.
