LECTING WORKING MODE (3-195)
NOTICE
When this tool control system is fitted the factory flow set-
ting on the machine will be set to minimum, do not adjust
this value as doing so will have no effect on the attach-
ment performance.
NOTICE
When operating in P, E or L mode select ATTACHMENT 16
OFF as the attachment pre-set, this will deactivate the at-
tachment controls for standard digging or lifting opera-
tions.
SYSTEM ERRORS
The system automatically monitors for system abnormalities, in the event of an error the monitor display screen
(7) will display ERR and an audible intermittent buzzer will sound. In the event of a system error, stop work im-
mediately, move the machine to a safe place and contact your Komatsu distributor for support.
TRACK SHOES SELECTION
Select the appropriate track shoe to match the operating conditions.
Track shoes selection
Confirm the category from the list of uses in Table 1, then use Table 2 to select the shoe.
• Categories B and C are wide shoes, so there are limitations on their use. When using these shoes, check
the precautions, then investigate and study fully the conditions of use to confirm that these shoes are suita-
ble.
• When selecting the shoe width, select the narrowest shoe possible that will give the required flotation and
ground pressure. If a wider shoe than necessary is used, the load on the track will increase, and this will
cause shoes to bend, links to crack, pins to break, shoe bolts to come loose and various other problems.
