Before checking the adjustment of the wastegate valve, it should be possible to move the wastegate arm able to its outer positions.

1. Set the pressure to max according to the table by turning clockwise.
2. Note the movement of the wastegate arm.
3. Release the pressure completely by turning counter clockwise.

The arm should move relatively smoothly. Some rubbing may occur. Repeat instructions 1-3 at least twice so that the arm moves smoothly.
