8. PRECAUTIONS FOR MAINTENANCE A WARNING: For reasons of safety, always follow these safety precautions. Do not bend high-pressure hoses or hit them with hard objects. Do not use any bent or cracked piping, tubes or hoses. They may burst during use. Always repair any loose or broken fuel hoses or oil hoses. If fuel or oil leaks, it may cause a fire. Avoid torching, soldering or welding on pipes, tubes or equipment that contain fuel or oils. If heated they can generate flammable fumes or mist and could cause a fire or explosion. + When repairing the electrical system or when carrying out electrical welding, remove the negative (-) terminal of the battery to stop the flow of current.
Do not forget that the work equipment circuits are always under pressure. Do not add oil, drain oil, or carry out maintenance or inspection before completely releasing the internal pressure. If you are hit by a jet of high pressure oil, consult a doctor immediately for medical attention. If oil is leaking under high pressure from small holes, it is dangerous if the jet of high pressure oil hits your skin or enters your eyes. Always wear safety glasses and thick gloves, and use a piece of cardboard or a sheet of wood to check for oil leakage. Immediately after stopping machine operations, the engine coolant and oil at all parts are at high temperatures and under high pressure.
In this condition, if the radiator cap is removed, or the oil or coolant are drained, or the filters are replaced, this may result in burns or other injury. Wait for the temperature to go down, then carry out the inspection and maintenance in accordance with the procedures given in this manual. . . Cleaning inside of cooling system + see 24.
