MAINTENANCE
STORE OIL AND FUEL
•
Keep oil and fuel indoors to prevent any water, dirt, or other impurities from getting in.
•
When keeping drum cans for a long period, lay the drums so that the filler ports of the drums are located in
the lower part of the side to prevent moisture from being sucked in. If drums have to be stored outside, cov-
er 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).
STORE DEF
•
Completely seal up its container for storage. Only open containers in a well-ventilated area.
•
When storing DEF, avoid direct sunlight. Always use the original container. Make sure that transfer equip-
ment and tank must meet DEF compatible material specification. If DEF is stored in an iron or aluminum
container, toxic gas may develop and a chemical reaction may corrode the container.
•
The relationship between the upper limit of storage temperature and the storage period of DEF is shown in
the table.
Temperature of storage area
Max.10 °C {50 °F}
Max.25 °C {77 °F}
Max.30 °C {86 °F}
Max.35 °C {95 °F}
*: Do not store DEF in the temperature of 35 °C {95 °F} or above.
FILTER
•
Filters are extremely important safety parts. They prevent impurities in the oil, fuel, and air circuits from en-
tering important equipment and causing problems. Replace all filters periodically. For details, see Operation
and Maintenance Manual.
However, when working in severe conditions, replace the filters at shorter intervals according to the oil and
fuel (sulfur content) being used.
•
Never try to clean and use again the filters (cartridge type). Always replace them with new filters.
•
When replacing oil filters, check if any metal particles are attached to the old filters.
If any metal particles are found, consult your Komatsu distributor.
•
Do not open packages of spare filters until just before they are to be used.
•
Komatsu recommends using Komatsu genuine filters.
Storage period
Up to 36 months
Up to 18 months
