1. When starting the engine, check that the joystick lever is at the
N position, that the transmission directional lever is at the N
position, and that the surrounding area is safe.
REMARK
Under the following conditions, a warning may be given when the
engine is started.
If the directional selector switch on the joystick is at F or R, the
joystick pilot lamp flashes, the central warning lamp lights up,
and the alarm buzzer sounds.
In this condition, the engine will not start, so set the directional
selector switch to N.
If the joystick is not at the N position, the joystick pilot lamp
flashes, the central warning lamp lights up, and the alarm
buzzer sounds.
In this condition, the engine will not start, so set the joystick to
the N position.
2. When using the joystick, set the joystick ON/OFF switch to
position (a) to activate the joystick steering system.
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 travels
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).
