2.
Press (a) on the joystick ON/OFF switch to turn ON.
3.
The machine turns to the right when you tilt the joystick
steering lever toward (b) and to the left when you tilt it to-
ward (a).
The larger the joystick steering lever tilts, the faster the ar-
ticulation speed becomes.

When the articulation angle reaches the desired level, re-
turn the joystick steering lever to NEUTRAL position (N).
The joystick steering lever returns automatically to NEU-
TRAL position (N).
5.
In order to return the machine to the straight travel, tilt the
joystick steering lever from NEUTRAL position (N) in the
opposite direction to which the machine has been turned (i.e. to the left when it has been turned to the
right).
6.
Switch the forward and reverse travel of transmission by
using the directional selector switch on the top of the joy-
stick steering lever.
Position F: FORWARD
Position N: NEUTRAL
Position R: REVERSE
When the position of the directional lever is different from
that of the directional selector switch on the joystick steer-
ing lever, the centralized warning lamp lights up, and alarm
buzzer sounds.
In this condition, the machine travels forward and reverse in accordance with the directional lever position.
Set the directional lever to NEUTRAL position (N).
