MULTI-FUNCTION TYPE

HOLD SWITCH

When hold switch (1) is pressed in the auto transmission mode,
the drive speed gear stage displayed on the monitor is main-
tained. To deactivate the switch function, press hold switch (1)
again, change the drive speed range, change the drive mode,
or press either of the DSS or USS switch.

DSS (DOWN SHIFT) SWITCH

When DSS switch (2) 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 travel gear stage is set.
Then, when switch (2) 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 the forward/
reverse lever (5) is moved to the reverse position or when the
forward/reverse switch (4) is turned to the R position, the ma-
chine drive speed is automatically increased to the 2nd gear
stage.

USS (UP SHIFT) SWITCH

When USS switch (3) is pressed, the drive gear stage is up shift-
ed within the switch shifting range.
NOTE: When USS switch (3) is pressed once at a time, the
machine drive 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 drive speed is shifted down
from the 4th gear to the 2nd gear. Continuous up shift
operation with USS switch (3) is not achieved.
