• 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 (machines equipped with cameras) to ensure good
visibility, there are places that cannot 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 head lamps 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.
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 industrial waste is handled. Always observe the follow-
ing.
• 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 an approved respirator.
