DEF FILTER
The DEF filter is a filter element to clean the DEF sucked from
the DEF tank by DEF pump, and to supply it to the DEF injec-
tor.
NOTICE
• The DEF filter element needs to be replaced every
2000 hours.
• If the machine is operated without the DEF filter at-
tached, or with the filter other than Komatsu genuine
parts, foreign materials may enter the DEF pump and
DEF injector which will cause failure of the machine.
Never operate the machine without the DEF filter at-
tached, nor use the filter other than Komatsu genuine
parts.
• The DEF filter cannot be flushed. Flushing or regener-
ating of it will degrade the performance of the DEF fil-
ter, and will contaminate the DEF pump and the DEF
injector which will cause the failure of the machine.
Never reuse the DEF filter.

WARNING
• 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 starting switch key is in OFF position, KOMTRAX system consumes a small amount of elec-
tric power.
It is recommended to start 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 prevents the battery power from being con-
sumed, 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.
