    HANDLING OIL, FUEL, COOLANT, AND PERFORMING OIL CLINIC

    OIL

    Oil is used for the engine and hydraulic equipment under extremely severe conditions (high temperature, high- pressure), so the oil deteriorates with use.

    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.

    Never mix oils of different grades or brands.

    When the machine is shipped from the factory,T010 (power train oil) is used for the hydraulic system.

    FUEL

    Always use fuel that matches the temperatures given in the Operation and Maintenance Manual.

    COOLANT AND WATER FOR DILUTION

    This machine is filled with Komatsu genuine super coolant (AF-NAC) at the factory. This super coolant has the important function of preventing corrosion in the cooling system as well as preventing freezing.

    The ratio of Supercoolant (AF-NAC) to water differs according to the ambient temperature.

    GREASE

    The nipples not included in the MAINTENANCE section are nipples used when overhauling, so they do not need grease.

    Always wipe off all of the old grease that is pushed out when greasing.

    KOWA ANALYSIS ITEMS

    Precautions when sampling

    STORING OIL AND FUEL

    When keeping drum cans for a long period, put the drum on its side so that the filler port of the drums is at the side to prevent moisture from being sucked in.

    FILTERS

    Filters are extremely important safety parts. They prevent impurities in the fuel and air circuits from entering important equipment and causing problems.

    OUTLINE OF ELECTRIC SYSTEM

    When installing electrical equipment, connect it to the special power source connector.
