LUBRICANTS, COOLANT AND FILTERS
Keep indoors to prevent any water, dirt, or other impurities from getting in.
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.
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 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.
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 affixed 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 Komatsu genuine filters.
ELECTRIC SYSTEM MAINTENANCE
It is extremely dangerous if the electrical equipment becomes wet or the covering of the wiring is damaged. This
will cause electrical leakage 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.
Service relating to the electric system is check of fan belt tension, check of damage or wear in the fan belt and
check of battery fluid level.
Never install any electric components other than those specified by Komatsu.
External electro-magnetic interference may cause malfunction of the control system controller, so before
installing a radio receiver or other wireless equipment, please contact your Komatsu distributor.
When working at the seashore, carefully clean the electric system to prevent corrosion.
When installing electrical equipment, connect it to the special power source connector.
Do not connect the optional power source to the fuse, starting switch, or battery relay.
