Driving Mode Switch (Zw180) - Hitachi ZW180 Operator's Manual

DRIVING MODE SWITCH (ZW180)

Shifts the transmission-driving mode. When driving mode
switch (1) is in the M position, the transmission is set in the
manual mode so that the transmission gears are shifted with
the transmission gear selector. When driving the machine in
the auto shift mode, select one of three auto shift points. Ac-
cording to the conditions encountered in drive/work opera-
tion, select the desired position. When operating driving mode
switch (1), stop the machine. Then, after returning forward/re-
verse lever (2) to the N position, set driving mode switch (1).
Position M: Manual shift (The transmission gears are shifted
with the shift switch.)
Position 1-4L: Shift change (up/down) is performed in the
earlier stage with the engine running at slow
speed. Start to drive the machine with the 2nd-
gears. When the travel load increases, the gears
are automatically shifted from the 2nd gear
stage to the first gear stage. (Auto DSS function)
This travel mode contributes to achieve energy-
saving traveling since driving the vehicle with
the accelerator pedal in the half stroke reduces
the fuel consumption. (Applicable to general
works such as excavation, and loading, long
distance movement, climbing slopes and snow
removal in the 2nd-gear stage)
Position 2-4N: Shift change (up/down) is performed with
the engine running at faster speed than the L
mode. Shift-up from the 2nd to 3rd gear stage
is performed at faster speed than the L mode.
(Applicable to loading works and snow removal
in the 3rd or 4th gear stage auto shift mode)
Position 1-4H: Start to drive the machine wit the 2nd-gears.
Shift change is performed at the same timing
as the N mode. Shift change (up/down) is per-
formed at faster engine speed than the L mode.
When the travel load increases, the gears are
automatically shifted from the 2nd gear stage
to the first gear stage. (Auto DSS function) (Ap-
plicable to excavation, and loading works and
climbing slopes in the 3rd or 4th gear stage
auto shift mode)
Refer to the DRIVING MACHINE section for more detailed infor-
mation.
NOTE: When the machine is operated in the auto transmission
mode, the travel speed is shifted up to the gear stage
set by the transmission gear selector. When the 4th
gear stage is selected, the travel speed is automatically
shifted from the 2nd in to the 4th gears. When the 3rd
gear stage is selected, the travel speed is automatically
shifted from the 2nd in to the 3rd gears.
