OPERATION
GEARSHIFTING USING SHIFT MODE SELECTION
Shift mode selection means that the selected speed range is displayed in N position before starting.
When the joystick (steering, directional and gear shift lever) is in
N position, if UP switch (a) or DOWN switch (b) is pressed, the
shift mode selection can be performed.
The selected shift mode is displayed on display panel B
(multi-information) of the monitor panel.
Shift operation when [F1-R2] mode is set
When the joystick is in N position, if the up switch is pressed once, the mode is set to [F1-R2] mode. After that,
if the joystick is operated forward (forward travel operation), the transmission is shifted to F1. If it is moved back
(reverse travel operation), the transmission is shifted to R2.
Shift operation when [F2-R2] mode is set
When the joystick is in N position, if the up switch is pressed twice, the mode is set to [F2-R2] mode. After that,
if the joystick is operated forward (forward travel operation), the transmission is shifted to F2. If it is moved back
(reverse travel operation), the transmission is shifted to R2.
