OPERATION

SHIFTING GEAR

Since gear can be shifted during machine travel, the machine need
not to be stopped to shift gears.
1. Move joystick (steering, directional and gear shift lever) (1) to
the desired gear position to shift gears.
GEAR SHIFTING
When the joystick is at FORWARD or REVERSE position and
switch (a) or switch (b) is pushed, the transmission speed will
change.
UP switch (a): Each time the switch is pressed, the transmission
will shift up one speed.
DOWN switch (b): Each time the switch is pressed, the
transmission will shift down one speed.
When the lever is moved to the forward (to set to FORWARD) from N position, the transmission shifts to F1.
If the UP switch is pressed once when the transmission is in F1, the transmission shifts to F2.
If the UP switch is pressed once when the transmission is in F2, the transmission shifts to F3.
If the DOWN switch is pressed once when the transmission is in F3, the transmission shifts to F2.
If the DOWN switch is pressed once when the transmission is in F2, the transmission shifts to F1.
When the lever is moved to the rear (to set to REVERSE) from N position, the transmission shifts to R1.
If the UP switch is pressed once when the transmission is in R1, the transmission shifts to R2.
If the UP switch is pressed once when the transmission is in R2, the transmission shifts to R3.
If the DOWN switch is pressed once when the transmission is in R3, the transmission shifts to R2.
If the DOWN switch is pressed once when the transmission is in R2, the transmission shifts to R1,
For details of the maximum speed in each speed range, see "SPECIFICATIONS (PAGE 5-2)".
