Filters 0.
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.
Biodegradable hydraulic oil and lubricants 0.
The use of biodegradable hydraulic oils and lubricants - on the basis of synthetic esters - for Komatsu machines is
permitted. For information on the products cleared for use and best suited for your application contact our autho-
rized service workshops.
Outline of electric system 0.
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 com-
ponents.
Service relating to the electric system is checking fan belt tension, checking damage or wear in the fan belt and
checking 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 install-
ing 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.
The optional power source must never be connected to the fuse, starting switch, or battery relay.
