SAFETY GENERAL PRECAUTIONS 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. Position a signalman if there are areas at the rear of the machine where the visibility is not good. 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. CHECKING SIGNALMAN'S SIGNALS AND SIGNS 0. 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. EMERGENCY EXIT FROM OPERATOR'S CAB 0. Machines equipped with a cab have doors on the left and right sides. If the door on the one side does not open, escape from the door on the other side. VENTILATION FOR ENCLOSED AREAS 0. Asbestos dust in the air can cause lung cancer if it is inhaled.
There is danger of inhaling asbestos when working on jobsites handling demolition work or work handling industrial waste. Always observe the following. Spray water to keep down the dust when cleaning. Do not use compressed air for cleaning. If there is danger that there may be asbestos dust in the air, always operate the machine from an upwind position. All workers should use an approved respirator. Do not allow other persons to approach during the opera- tion. Always observe the rules and regulations for the work site and environmental standards. This machine does not use asbestos, but there is a danger that imitation parts may contain asbestos, so always use genuine Komatsu parts. 2-13
