3.9. Joystick operation of the 3
d
brush (optional)
(fig. 1, no. 18)
This joystick operates the third brush. The third brush has two swivel points, each with a separate
swivel motor. The position of the joystick determines the rotation of the swivel motors in the
horizontal plane. Which of the two swivel motors is operated, depends on the direction in which the
joystick is moved:
•
press left to turn the first brush arm anti-
clockwise.
•
press right to turn the first brush arm
clockwise.
•
press forward to turn the second brush arm
anti-clockwise.
•
pull backward to turn the second brush arm
clockwise.
•
by pushing the joystick diagonally, both
swivels will turn simultaneously, making the
third extremely flexible.
The joystick has three function switches:
- Rotate 3
d
brush
- 3
d
brush up/down
- Angle adjustment of 3
d
brush
Good control of the third brush can only be realised through thorough training.
Inexpert operation could cause damage to the vehicle and/or the third brush system and
give rise to hazardous situations.
