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 con- firmed that the electricity has been shut off. Also, do not let anyone come close to the machine. Ensure Good Visibility 0. Check for any persons or obstacles in the area around the machine and check the conditions of the jobsite to ensure that operations and travel can be carried out safely. Always do as follows.
When working in dark places, turn on the working lamp and front lamps installed on 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. Ventilation for Enclosed Area 0. Exhaust fumes from the engine can kill. If it is necessary to start the engine within an enclosed area, or when handling fuel, flushing oil, or paint, open the doors and windows to ensure that adequate ventilation is provided to prevent gas poisoning. Signalman's Signal and Signs 0. Set up signs to inform of road shoulders and soft ground. If the visibility is not good, position a signalman if nec- essary.
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. Emergency Exit from Operator's Cab 0. If for any reason it becomes impossible to open the cab door, use the hammer supplied to break the window and use it as an emergency escape. For details, see "EMERGENCY ESCAPE HAMMER ( 3-24 )" in this manual. When escaping, remove all the pieces of glass from the window frame first and be careful not to cut yourself on the glass. Be careful also not to slip on the broken pieces of glass on the ground.
