. SAFETY PRECAUTIONS FOR OPERATION 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 ensure good visibility, but even then there are places that cannot be seen from the operator's seat, so be careful when operating.
When traveling or carrying out operations in places with poor visibility, it is impossible to check for obstacles in the area around the machine and to check the condition of the jobsite. This leads to danger of serious personal injury or death. When traveling or carrying out operations in places with poor visibility, always observe the following. Position a signalman if there are areas where the visibility is not good. Only one signalman should give signals. 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. When checking the mirrors installed to the machine, remove all dirt and adjust the angle of the mirror to ensure good visibility. CHECKING SIGNS AND SIGNALMAN'S SIGNALS 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. Only one signalman should give signals. Make sure that all workers understand the meaning of all signals and signs before starting work.
