OM2032 03/13 Safety - Section 20 Page 20-13 Precautions With The Battery When repairing the electrical system or when performing electrical welding, remove the negative (-) terminal of the battery to stop the flow of current. Precautions When Performing Maintenance Near High Temperature Or High Pressure Immediately after stopping operation, engine coolant and operating oils are at high temperature and under high pressure. In these conditions, if the cap is removed, the oil or water drained, or the filters are replaced, it may result in burns or other injury.
Wait for the temperature to cool and pressure to subside, before performing the inspection and/or maintenance as outlined in the service manual. Handling High Pressure Hoses DO NOT bend high-pressure hoses or hit with hard objects. DO NOT use any bent or cracked piping, tubes or hoses. They may burst during use. Rotating Fan And Belts Always repair any loose or broken hoses. Fuel or oil leaks may result in a fire. Stay away from rotating parts such as the radiator fan and fan belts. Serious bodily injury may result from direct or indirect contact with rotating parts and flying objects. Precautions With High Pressure Oil Work equipment circuits are always under pressure.
DO NOT add oil, drain oil, or perform maintenance or inspections before completely releasing the internal pressure. Small, high pressure pin-hole leaks are extremely dangerous. The jet of high-pressure oil can pierce the skin and eyes. Always wear safety glasses and thick gloves. Use a piece of cardboard or a sheet of wood to check for oil leakage. Waste Materials Never dump waste oil into a sewer system, river, etc. Always put used oil in appropriate containers. Never drain oil directly onto the ground. If you are hit by a jet of high-pressure oil, consult a doctor immediately for medical attention.
Obey appropriate laws and regulations when disposing of harmful objects such as oil, fuel, coolant, solvent, filters, batteries, etc.
