OPERATION
DEF FILTER
DEF filter is an filter element to clean DEF sucked from the
DEF tank by DEF pump, and to supply it to DEF injector.
NOTICE
• The DEF filter element needs to be replaced every
2000 hours.
• If the machine is operated without DEF filter attached,
or with the filter other than Komatsu genuine parts,
foreign materials may enter into DEF pump and DEF
injector which will cause failure of the machine. Never
operate the machine without DEF filter attached, nor
use the filter other than Komatsu genuine parts.
• DEF filter cannot be flushed. Flushing or regenerating
of it will degrade the performance of DEF filter, and will
contaminate DEF pump and DEF injector which will
cause the failure of the machine. Never reuse the DEF
filter.
KOMTRAX
• Never disassemble, repair, modify, or move the wireless communication terminal, antenna, or ca-
bles. This may cause failure or fire on the wireless equipment or the machine itself.
• Near the blasting jobsite, there may be a danger of unexpected explosion due to use of the wireless
equipment and resulting serious personal injury or death.
If you have to operate the machine within 12 m from the remote-controlled blasting device, the pow-
er supply cable of the wireless communication device must be disconnected in advance.
KOMTRAX is a vehicle management system that remotely manages the machines equipped with the KOM-
TRAX device by using satellite communication or portable radio communication.
The GPS (Global Positioning System), receiver, and communication system are equipped in the vehicle man-
agement system.
The machine information such as the machine maintenance, maintenance management, operating situation
management, and machine location management is gathered from the inside network of the machine. It can be
useful for you to perform the machine management by yourself. Your Komatsu distributor uses the above ma-
chine information for supply of service to the customers, improvement of our products and service, etc.
The type of information which is sent from the machine may vary depending on the machine. For the radio sta-
tion establishment of KOMTRAX, consult your Komatsu distributor.
POWER SUPPLY FOR KOMTRAX
• Even when the key in the starting switch of the KOMTRAX system is at OFF position, a small amount of
electric power is consumed.
It is recommended to run the engine periodically to charge the battery.
• When using the battery disconnect switch, turn the starting switch to OFF position and, after checking that
the system operating lamp is not lit, set the battery disconnect switch key to OFF position and pull it out.
When the battery disconnect switch is turned to OFF position, it is possible to prevent power consumption
of the battery, but the functions of KOMTRAX stop at the same time.
• If the power supply cable of KOMTRAX system device has to be disconnected, contact your Komatsu dis-
tributor.
