2) Use a signalman to give warning if the machine approaches too close to the electric cable.
• If the work equipment should touch the electric cable, the operator should not leave the operator’s compart-
ment.
• When carrying out operations near high voltage cables, do not let anyone come close to the machine.
• Check with the electricity company about the voltage of the cables before starting operations.
