. SAFETY GENERAL PRECAUTIONS may cause serious injury or necessary action. 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. Wear rubber-soled shoes and rubber gloves for fear of an electric shock and be careful that any unprotected body part will never touch the machine. 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. Should the machine have got too close to an electric wire or come to contact with it, the operator must not leave the machine, but stay in the operator's platform, in order to avoid a risk of electric shock, until the electricity is switched off. Likewise do not allow anyone to come close to the machine.

Chec k the terrain and condition of t he ground at the worksite, and determin e the safest meth od of operati on. Do not ca rry out operations at places where there is a hazard of landslides or falling rocks. If wat er lines, gas lines, or high-volt age electrical lines may be buried under the worksite, con tact each util ity and identif y their locations. Be careful n ot to sever or damage any of these line Take action to prevent unauthorize d people from approaching the jobsite. When When traveling or operating in shall ow water or on soft ground, check the sh ape and condition of the bedroc k, and the de pth and speed of flow of the water before starting operations.
WORKING ON LOOSE GROUND Avoid traveling or operating your machine too close to the edge of cliffs, overhangs, and deep ditches. The Avoid groun d may be weak in such areas . If the ground should collapse under th e weight or vibra tion of the ma chine, there is a hazard that the machine may fall or tip over. Remember that the s oil after heavy rai n or blasting or after earthquakes is weak in these area s. When working on embankments or near excavated ditches, there is a haza rd that the weight and vibration of the machine will cause the soil to colla pse. Before starting operations, take st eps to ensure tha t the ground is safe and to prevent the machine from r olling over or falling.
