EMERGENCY CONTROL

ELECTRICAL SYSTEM BREAKDOWN
If a breakdown occurs in the electrical system or the solenoid valve solenoids, the clutches can be
engaged manually with a mechanical system. To operate this system, remove the cap [2] (Fig. 2),
press the button [3] (Fig. 3) and turn anti-clockwise.

To reset the electrical control valve, torque the cap [2] to 7 Nm.
Torque the solenoid valves to 27 Nm if they have been replaced or removed.
Never perform this operation on both valves at once, as both clutches will engage at the same
time and cause the transmission to lock up.
