MAINTENANCE OUTLINES OF SERVICE OUTLINES OF SERVICE HANDLING OIL, FUEL, COOLANT, AND PERFORMING OIL CLINIC OIL Oil is used in the engine and hydraulic equipment under extremely severe conditions (high temperature, high pressure), and deteriorates with use. Always use oil that matches the grade and maximum and minimum ambient temperatures recommended in the Operation and Maintenance Manual. Even if the oil is not dirty, always change the oil at the specified interval. Oil corresponds to blood in the human body, always be careful when handling it to prevent any impurities (water, metal particles, dirt, etc.) from getting in.
The majority of problems with the machine are caused by the entry of such impurities. Take particular care not to let any impurities get in when storing or adding oil. Never mix oils of different grades or brands. Always add the specified amount of oil. Having too much oil or too little oil are both causes of problems. If the oil in the work equipment is not clear, there is probably water or air getting into the circuit. In such cases, please contact your Komatsu distributor. When changing the oil, always replace the related filters at the same time. We recommend you have an analysis made of the oil periodically to check the condition of the machine.
