. SAFETY GENERAL PRECAUTIONS 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 operatingor 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. In areas where it is impossible to confirm the area behind the machine and observation cameras have been set up, clean off any dirt from the lens and make sure that the camera gives a clear view of the rear. 2 - 19 DISTANCE TO HIGH VOLTAGE CABLES Do not tr avel or operate the machine nea r electric cables.
There is a hazar d of electric shock , which may cause s erious injury or property damage. On jobsites where the machine may go close to electric c able s, always do as follows . Befor e starting work nea r electric cables, inform the local power company o f the work to b e performed, and ask them to take t he necessary action.
