It is necessary to perform this adjustment separately on the left and right hydraulic cylinders for the trunk lid (1).

1. Slacken lock nut (5).
2. Completely push piston rod into hydraulic cylinder for trunk lid actuation (1) by hand.
3. Turn ball head (6) until the ball head (6) can be attached to the tubular frame (2).
4. Attach ball head (6) to tubular frame (2) for checking and then unclip.

   It must be possible to attach the ball head (6) without tension.

5. Turn ball head (6) one turn clockwise and tighten locknut (5).

   Ensure that the reach of the ball head (6) on the thread on the piston rod is not less than 8 mm. Otherwise, the thread on the piston rod can be damaged.
