4.2 Outlines of service Handling oil, fuel, coolant, grease and carrying out KOWA (KOMATSU Oil Wear Analysis) Maintenance Oil sampling z Sampling interval 250 hours: Engine 500 hours: Other components z Precautions when sampling Ѓ Make sure that the oil is well mixed before sampling. Ѓ Carry out sampling regularly at fixed intervals. Ѓ Do not carry out sampling on rainy or windy days when water or dust can get into the oil. For further details of KOWA, please contact your KOMATSU dis- tributor. Storing oil and fuel z Keep indoors to prevent any water, dirt, or other impurities from getting in.
z When keeping drum cans for a long period, put the drum on its side so that the filler port of the drum can is at the side to prevent moisture from being sucked in. If drum cans have to be stored outside, cover them with a waterproof sheet or take other measures to protect them. z To prevent any change in quality during long-term storage, be sure to use in the order of first in - first out (use the oldest oil or fuel first). Filters z Filters are extremely important safety parts. They prevent impurities in the fuel and air circuits from entering important equipment and causing problems. Replace all filters periodically. For details, see the Operation and Maintenance Manual.
However, when working in severe conditions, replace the fil- ters at shorter intervals according to the oil and fuel (sulfur content) being used. z Never try to clean the filters (cartridge type) and use them again. Always replace with new filters. z When replacing oil filters, check if any metal particles are affixed to the old filter. If any metal particles are found, please contact your KOMATSU distributor. z Do not open packs of spare filters until just before they are to be used. z Always use KOMATSU genuine filters. 4-8 WA150-5H – VEAM934100
