5 Maintenance Storing oil and fuel Keep oil and fuel indoors to prevent any water, dirt or other impurities from penetrating. When keeping barrels for a long period, lay down the barrel on its side so that the filler port is at the side (to prevent moisture from being sucked in). If barrels have to be stored outside, cover them with a waterproof sheet or take other measures to protect them. 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 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 under severe conditions, it is necessary to consider replacing the filters at shorter intervals according to the oil and fuel (sulfur content) being used. Never try to clean the filters (cartridge type) and use them again. Always replace with new filters. When replacing oil filters, check if any metal particles are stuck to the old filter. If any metal particles are found, please contact your Komatsu distributor.
Do not open packs of spare filters until just before they are to be used. Always use original Komatsu filters. Biodegradable hydraulic oil and lubricants The use of biodegradable hydraulic oils and lubricants - on the basis of synthetic esters - for Komatsu machines is permitted.
