4.2.1.5 STORING OIL AND FUEL
q Keep oil and fuel indoors to prevent any water, dirt, or other impurities from getting into them.
q When storing drums for a long period, position them on one side, so that the opening is lateral. This prevents
moisture from being sucked in through the drum filling opening.
If drums have to be stored outside, cover them with a waterproof sheet or take other measures to protect them.
q To prevent any change in quality during long-term storage, be sure to use the fluids following the first in - first out
(use the oldest oil or fuel first) method.
4.2.1.6 FILTERS
q Filters are very important components for safety. They prevent any impurities from getting into the oil, fuel, or in
the air circuits, thus avoiding problems to important components of the machine.
Periodically change all the filters. For further information, see the relevant Use and Maintenance manual.
However, when working in extreme conditions, it is necessary to change the filters more frequently, depending
on the type of oil and fuel used (sulphur content).
q Do not attempt to clean the filters (type with cartridge) and reuse them. Always change them with new filters.
q When changing the oil filters, check if metal particles are present. If you find large quantities of metal particles,
contact your Komatsu Dealer.
q Do not open the spare filter packages before using them.
q Always use Komatsu original spare parts.
