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.

from the pacemaker. The radio waves may have an adverse effect on the operation of the pacemak-
er.

sure to operate the machine away from the blasting jobsite.
If you have to operate the machine within 12 m from the blasting jobsite or the remote-controlled
blasting device, the power supply cable of KOMTRAX must be disconnected in advance. If you want
to do this, ask your Komatsu distributor for disconnecting power supply cable of KOMTRAX.
Also, if there are any requirements or regulations of the territory or country where the machine
equipped with the device is used, such requirements or regulations have a priority than this warn-
ing.

lite communications specifications.

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.
