Control system:
The blocking clutch is moved by the clutch drive fork. The fork is driven mechanically, through a special cable. The drive is controlled by a lever mechanism from the driver's seat. The control unit has a mechanism for guaranteed locking on (off). After moving the control lever to the on or off position, a spring mechanism is cocked, which presses the clutch drive fork to the zero position points when starting to move.
Important: The lock must be turned on and off when the vehicle is stopped.
