Rules for Refueling the Machine SAFETY Grease, fuel, oil, or coolant spills can pose a trip hazard if not mopped up immediately. Be sure you are adding the correct fluids to the proper location. Mixing fluids or adding fluids to the wrong tank can cause damage to internal components. When refueling or adding any fluids, be sure you are in a well- ventilated area. Never smoke or allow open flames near you while you are refueling the machine. Never mix gasoline with diesel fuel. Gasoline is extremely flammable and could cause an explosion. Do not fill the fuel tank completely; leave room for the fuel to expand. Always clean up any spills.
Cooling System Precautions Never add coolant to a hot or warm engine. Always allow the engine time to cool down completely before opening the radiator cap. Never dump used coolant on the ground, in a lake, stream, or in a sewer system. Komatsu requires these fluids to be captured and recycled properly. Welding Precautions Welding operations must always be carried out by a qualified welder and in a place equipped with proper equipment. There is a hazard of gas, fire, or electrocution when carrying out welding. Never allow any unqualified personnel to carry out welding.
Battery Precautions When working on the electrical system, disconnect the negative (-) battery cable first then the positive (+) battery cable last. On completion of work, reconnect the positive (+) cable first then the negative (-) cable last . WA380-6 1-39
