MAINTENANCE
4-8
STORING OIL AND FUEL 4
q
Keep indoors to prevent any water, dirt, or other impurities from getting in.
q
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.
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 in the order of first in - first out (use
the oldest oil or fuel first).
FILTERS 4
q
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 filters at shorter intervals according to the oil and fuel
(sulfur content) being used.
q
Never try to clean the filters (cartridge type) and use them again. Always replace with new filters.
q
When replacing oil filters, check if any metal particles are attached to the old filter. If any metal particles are
found, contact your Komatsu distributor.
q
Do not open packs of spare filters until just before they are to be used.
q
Use of Komatsu genuine filter elements is strongly recommended.
OUTLINE OF ELECTRIC SYSTEM 4
q
It is extremely dangerous if the electrical equipment becomes wet or the covering of the wiring is damaged.
This will cause an electrical short circuit and may lead to malfunction of the machine. Do not wash the inside of
the operator's cab with water. When washing the machine, be careful not to let water get into the electrical
components.
q
Service relating to the electric system is checking fan belt tension, checking damage or wear to the fan belt
and checking battery fluid level.
q
Never install any electric components other than those specified by Komatsu.
q
External electro-magnetic interference may cause malfunction of the control system controller, so before
installing a radio receiver or other wireless equipment, contact your Komatsu distributor.
q
Be careful to keep the electric system free of water when washing the machine or when it rains.
q
When working at the seashore, carefully clean the electric system to prevent corrosion.
q
When installing an operator's cab cooler or any other electrical equipment, connect it to an independent power
source connector. The optional power source must never be connected to the fuse, starting switch, or battery
relay.
