8. PRECAUTIONS FOR MAINTENANCE -I PRECAUTIONS WITH BATTERY l When repairing the electrical system or when carrying out electrical welding, remove the negative (-) terminal of the battery to stop the flow of current. HANDLING HIGH-PRESSURE HOSES 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 and equipment that contain fuel or oils. If heated, they can generate flammable fumes or mist and could cause a fire or explo- sion.
-I PRECAUTIONS WITH HIGH PRESSURE OIL 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 re- leasing the internal pressure. 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. If you are hit by a jet of high-pressure oil, consult a doctor immediately for medical at- tention. 1-19
