7. PRECAUTIONS DURING OPERATION WARNING: For reasons of safety, always follow these safety precautions. 1-14 DO NOT GO CLOSE TO HIGH-VOLTAGE CABLES ‡ Do not let the machine touch overhead electric cables. Even going close to high-voltage cables can cause electric shock. Always maintain the safe distance given below between the machine and the electric cable. ‡ To prevent accidents, always do as follows. • On jobsites where there is danger that the machine may touch the electric cables, consult the electricity company before starting operations to check that the actions determined by the relevant laws and regulations have been taken. • Wear rubber shoes and gloves.
Lay a rubber sheet on top of the operator’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. • If the work equipment should touch the electric cable, the operator should not leave the operator’s compartment. • 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.

‡ Stop operations if the visibility is poor, such as in mist, snow, or rain, and wait for the weather to improve to a condition that allows the operation to be carried out safely. DO NOT HIT WORK EQUIPMENT ‡ When working in places where there are height limits, such as in tunnels, under bridges, under electric cables, or in garages, be extremely careful not to hit the work equipment.
