WARNING: For reasons of safety, always follow these safety precautions. SAFETY 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. HANDLING HIGH-PRESSURE HOSES Always repair any loose or broken fuel hoses or oil hoses. If fuel or oil leaks, it may cause a fire. 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. Oil leaking under high pressure, even from small holes, is dangerous.
A jet of high-pressure oil that hits the skin or enters the eye can cause serious injury. Always wear safety glasses and thick gloves, and use a piece of cardboard or a sheet of wood to check for oil leakage. Obtain medical attention immediately for anyone struck by a jet of high-pressure oil. Immediately after stopping machine operations, the engine cooling water and oil at all parts remain at high temperatures and under high pressure. The hot fluids will cause burns and/or other injury if the radiator cap is removed, or the oil or water are drained, or the filters are replaced.
Wait for the temperature to go down, then carry out the inspection and maintenance in accordance with the procedures given in this manual.
