PRECAUTIONS TO BE TAKEN DURING MAINTENANCE Disconnet both the battery and the alternator before performing any welding on the machine. D00353 7.11 PRECAUTIONS REGARDING HIGH PRESSURE HOSES Do not bend or scratch high pressure hoses with sharp or abrasive objects. Do not use bent or cracked pipes or hoses which have been previously rejected because of leaks or other defects. Faulty hoses can burst during operation. Repair or replace immediately any loose or faulty fuel or hydraulic lines. Fuel or oil leaks can cause fires. 7.12 PRECAUTIONS TO BE TAKEN WHEN WORKING ON HIGH PRESSURE SYSTEMS Remember that working hydraulic circuits are always under pressure.
If you have to add or drain hydraulic fluid, or service or inspect the hydraulic circuit, lower the equipment to the ground and release circuit pressure and resid- ual tank pressure before starting work. Leaks from pressurised hydraulic lines are extremely dangerous since the spray from them can penetrate the skin and enter the blood- stream, or enter the eyes. Always wear thick gloves and protective gog- gles when working on the hydraulic circuit. Use a sheet of cardboard or plywood to search for leaks. If you are struck by a jet of hydraulic fluid under pressure, or if you are injured even slightly, con- sult a doctor immediately for medication and appropriate treatment. DANGEROUS!
