ENSURE GOOD VISIBILITY
This machine is equipped with mirrors to improve the visibility, but even with mirrors, there are places, which can-
not be seen from the operator's seat, so always be careful when operating.
When operating or traveling in places with poor visibility, if it is impossible to confirm the condition of the job side or
obstacle is in the area around the machine, there is danger that the machine may suffer damage or the operator
may suffer serious personal injury. When operating or traveling in places with poor visibility, always observe the
following items strictly.
q
If the visibility cannot be sufficiently assured, position a flagman if necessary. The operator should pay careful
attention to the signs and follow the instructions of the flagman.
q
The signals should be given only by one flagman.
q
When working in dark places, turn on the working lamps and front lamps of the machine, and if necessary, set
up additional lighting in the area.
q
Stop operations if there is poor visibility, such as in fog, snow, rain, or sand storms.
q
Check the mirrors on the machine before starting operations every day. Clean off any dirt and adjust the view
to ensure good visibility.
q
In areas where it is impossible to confirm the area behind the machine and observation cameras have been
set up, clean off any dirt from the lens and make sure that the camera gives a clear view of the rear.If there is
any problem with the camera and the rear view cannot be displayed, contact your Komatsu distributor immedi-
ately and ask for repairs to be carried out.
VENTILATION FOR ENCLOSED AREA
Exhaust fumes from the engine can kill.
q
If it is necessary to start the engine within an enclosed
area, or when handling fuel, flushing oil, or paint, open the
doors and windows to ensure that adequate ventilation is
provided to prevent gas poisoning.
SIGNALMAN'S SIGNAL AND SIGNS

Set up signs to inform of road shoulders and soft ground. If the visibility is not good, position a signalman if
necessary. Operators should pay careful attention to the signs and follow the instructions from the signalman.
q
Only one signalman should give signals.

Make sure that all workers understand the meaning of all signals and signs before starting work.
