OPERATION
Forward/reverse switching operation
(A) FORWARD
(N) NEUTRAL
(B) REVERSE
Move to the front to travel forward; move to the rear to travel in
reverse.
Steering operation
(L) Turn LEFT
(N) NEUTRAL
(R) Turn RIGHT
When the lever is tilted halfway in the direction you are turning
while it is tilted in FORWARD or REVERSE, the machine turns.
If the lever is tilted rightward or leftward until operating effort
becomes large, turning radius decreases from the one at loose
turn.
REMARK
• When steering mode is NORMAL mode, if lever is tilted to
the position where the operating effort to right or left be-
comes large, the machine makes pivot turn. When steering
mode is FINE mode, even if lever is tilted to the position
where the operating effort to right or left becomes large,
the machine does not make pivot turn.
Tilt the lever further, and the machine makes pivot turn.
• If the lever is released during steering operation, it returns
to (A) or (B), and the machine travels straight.
• If you perform steering operation by supporting your hand
with lever guide (G), performance of steering operation im-
proves.
Counter-rotation turn operation
During steering operation, if lever is tilted further from the position where the operating effort becomes large,
right and left tracks turn contrary direction to each other, and the machine makes counter-rotation turn.
Gear shift operation
The speed range is shifted by pressing switches (U) or (D)
while the joystick (steering, directional and gear shift lever) is in
FORWARD or REVERSE position.
(U) UP switch: The speed range is shifted up by 1 step each
time this switch is pressed.
(D) DOWN switch: The speed range is shifted down by 1 step
each time this switch is pressed.
For the maximum travel speed in each speed range, see
"SPECIFICATIONS (5-2)".
When the starting switch is turned to ON position, the speed
range is automatically set to 1st.
