Caution (2):
2. Setting procedure (For dump truck)
Set them in accordance with the following procedures:
2.1
It is impossible to set smaller values than the present values for "Service
Meter", "Travel Distance Integrated Value", and "Reverse Travel Distance
Integrated Value (dump track only)".
Before replacing the machine monitor, record the "Service Meter", "Travel Distance
Integrated Value", and "Reverse Travel Distance Integrated Value (dump track only)"
on the machine monitor.
For the checking method of "Service Meter", "Travel Distance Integrated Value", and
"Reverse Travel Distance Integrated Value", refer to "Explanation of Each Device,
Machine Monitor in Part: Operation in the Operation and Maintenance Manual" of the
machine.
Though it is necessary to set the "Service Meter", "Travel Distance Integrated Value", and
"Reverse Travel Distance Integrated Value (dump track only)" which are displayed on the
machine monitor when the machine monitor is replaced, the setting procedures of these
important information are not detailed in the Shop Manual so that they are not set
incorrectly, and this Service News introduces the setting procedures.
Since the execution items at the replacement of the machine monitor are detailed in Part:
Inspection and Adjustment in the Shop Manual be sure to refer to the Shop Manual.
This Service News describes about "Service Meter", "Travel Distance Integrated Value",
and "Reverse Travel Distance Integrated Value (dump track only)" out of the execution
items when the machine monitor is replaced.
When VHMS and KOMTRAX are installed, their data cannot be obtained
correctly unless the service meter is set.

(Note)
Checking method of Service Meter by data from the KOMTRAX
1) Login from the KOMTRAX Operation Screen.
2) Select the machine check list.
3) Record the "Latest Service Meter (H)" of the relevant machine.
For anything unclear about the KOMTRAX Operation Screen, contact
KOMTRAX Service Hot Line
Toll-free Number: 81-120-649-300 or mail address: cs_kom@komatsu.co.jp.
When the machine monitor is out of order and these values cannot be checked,
check the Service Meter by the VHMS and KOMTRAX data.
Since "Travel Distance Integrated Value" and "Reverse Travel Distance Integrated
Value" cannot be checked by data from the VHMS and KOMTRAX, record the value
that was checked by asking the machine controller.
When Service Meter cannot be checked because the VHMS and KOMTRAX are not
installed, record the value checked by asking the machine controller.
