. SAFETY SAFETY INFORMATION 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 come close to 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 come close to the machine.

Always do as follows. When working in dark places, turn on the working lamp and front lamps installed to the machine, and set up additional lighting in the work area if necessary. Stop operations if the visibility is poor, such as in mist, snow, rain, or dust.
