FINGER TYPE

HOLD SWITCH

During transmission auto mode operation, when hold switch
(1) is pressed, the speed gear stage displayed on the monitor
is maintained. When deactivating the hold switch, press the
hold switch again, shift the speed gear stage, change the travel
mode, press the DSS switch, or press the USS switch.

DSS/USS (DOWN SHIFT/ UP SHIFT) SWITCH

When the DSS side on DSS/USS switch (2) is pressed, the drive
gear stage can be shifted down within the switch shifting
range. When the USS side on DSS/USS switch (2) is pressed, the
drive gear stage can be shifted up within the switch shifting
range.

DSS (DOWN SHIFT) SWITCH

When DSS switch (3) is operated, the drive speed range can
be shifted within the switch shifting range. When the machine
is engaged in a normal work, the 2nd drive gear stage is set.
Then, when switch (3) is pressed during forward drive excava-
tion, the drive speed is automatically reduced to the 1st gear
stage so that excavation force is increased. When forward/
reverse lever (5) is moved to the reverse position or when
forward/reverse switch (4) is turned to the R position, the ma-
chine drive speed is automatically increased to the 2nd gear
stage.
NOTE: When either the DSS or USS side is pressed on the DSS/
USS switch once a time, the machine travel speed is
changed by 1 stage within the switch speed shift range
irrespective of the selected transmission mode, auto or
manual. In case the auto transmission mode is selected,
when the DSS switch is continuously pressed, the travel
speed is shifted down from the 4th gear speed to the
2nd gear speed. In case the USS switch is concerned,
continuous up shift operation is not achieved.
