Disarming the system

Fit the pre-tensioner (1), checking that the reference pin (PS) is centered in the corresponding housing for the central pillar (2) mounting bracket, then tighten the bolt (3) to the recommended torque (4 daNm). NOTE When the bolt (3) is tightened, the system is automatically reinforced.

DO NOT USE PERCUSSION TOOLS.

Complete the refitting, suitably reversing the order of the operations carried out for the removal.

Disarming the system

After having carried out the preliminary dismantling operations, undo the bolt (3) and extract the pre-tensioner (1) from the centre pillar (2). NOTE When the bolt (3) is loosened, the system is automatically disarmed. This state can be checked by observing that the end of the spring (ME) is pressing the arm (B2) of the second safety device lever towards the inside of the sensor (see diagram on previous page).
