Overview- system principle
This system is controlled by the roller integrated
on the pilot lever and a lock switch is provided on
the right upright of cab to control the application
of third linkage to avoid mis-operation.
For the machine with the pilot third linkage acting
as electronic control valve, the action of third
linkage is controlled via lock switch, in which
when the switch is under lock state, the
attachment controlled by pilot third linkage can
not work, the quick coupler cylinder is under lock
state, at which the working attachment can not
be installed and removed.
