Komatsu PW98MR-10 Operation & Maintenance Manual page 191

OPERATION
Komatsu Closed Crankcase Ventilation (KCCV)
KCCV is a device to clean the gas discharged from the engine
crankcase with the filter element and return it to the engine air
intake system.
NOTICE
• The KCCV filter element needs to be replaced every
2,000 hours. For details of the replacement procedure,
see "METHOD FOR REPLACING KCCV FILTER ELE-
MENT (4-75)".
• If the engine is operated without KCCV filter element
or if a filter element other than the Komatsu genuine
one is used, the engine sucks oil and foreign material
which can cause a failure. Always install Komatsu
genuine KCCV filter element.
• The filter element cannot be flushed. Never reuse the
filter element since it can cause a performance decre-
ment of engine, and it result in a failure even if it is
cleaned.
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 {within 39 ft 4 in} from the remote-controlled blasting
device, the power supply cable of the wireless communication device must be disconnected in ad-
vance.
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.
PRECAUTIONS FOR USING 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 storing the machine for a long
period, see "PRECAUTIONS FOR LONG-TERM STORAGE (3-223)".
• When using the battery disconnect switch, turn the starting switch to OFF position and turn the battery dis-
connect switch key to OFF position. Then, remove the key.
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.
For operation of the battery disconnect switch, see "BATTERY DISCONNECT SWITCH (3-121)".
• When using the satelite communication terminal, contact your Komatsu distributor before installing a top
guard or other attachment that covers the cab roof.
