6.2 Joystick steering system
2. Press the (a) part of the joystick ON/OFF switch to turn it
ON.
3. Operate the joystick in direction (b) to turn the machine to
the right; operate it in direction (a) to turn the machine to the
left.
The greater the angle of operation, the faster the articulating
speed becomes.
4. It is possible to switch the articulating speed with the HI/
LOW selector switch.
Select the speed to match the operation.
5. When the machine has articulated to the desired angle,
return the joystick to the N position.
The joystick will return automatically to the N position.
6. To return the direction of travel of the machine so that it trav-
els in a straight line, operate the joystick in the opposite
direction from the N position (for example, when the
machine is articulated to the right, operate the joystick to the
left).
7. Use the FNR switch at the top of the joystick lever to set the
transmission to the direction of travel.
N position: NEUTRAL
F position: FORWARD
R position: REVERSE
If the position of the directional lever and the FNR switch are
different, the joystick pilot lamp flashes, the warning lamp
lights up, and the alarm buzzer sounds.
In this condition, the machine will travel in the direction set
by the directional lever, so set the directional lever to N.
