Distance To High Voltage Cables; Ensure Good Visibility - Komatsu GALEO PC1250-8 Operation & Maintenance Manual

SAFETY

DISTANCE TO HIGH VOLTAGE CABLES

Do not travel or operate the machine near electric cables. There is
a hazard of electric shock, which may cause serious personal
injury or death. On jobsites where the machine may go close to
electric cables, always do as follows.
Before starting work near electric cables, inform the local power
company of the work to be performed, and ask them to take the
necessary action.
Even going close to high-voltage cables can cause electric
shock, which may cause serious burns or even death. Always
maintain a safe distance (see the table on the right) between the
machine and the electric cable. Check with the local power
company about safe operating procedure before starting
operations.
To prepare for any possible emergencies, wear rubber shoes
and gloves. Lay a rubber sheet on top of the 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 carrying out operations near high voltage cables, do not
let anyone near the machine.
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, do not let anyone near the machine.

ENSURE GOOD VISIBILITY

This machine is equipped with mirrors to improve the visibility, but even with mirrors, there are places, which cannot
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.
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.
The signals should be given only by one flagman.
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.
Stop operations if there is poor visibility, such as in fog, snow, rain, or sand storms.
Check the mirrors on the machine before starting operations every day. Clean off any dirt and adjust the view
to ensure good visibility.
