(c) Open the door.
(d) On the upper part and corners of the door, if necessary, apply one, two, or three shims (1) of Adhesive Film Tape-- Film PTFE - (Material No.05RAJ9) with a maximum thickness of 2 mm (0.0787 in.). Keep a distance of 10 mm (0.3937 in.) from the first shim edge before you apply the second shim.

NOTE: The same distance is also applicable before you apply the third shim.
(2) Check of the screws and nuts installation: (a) Make sure that the screws (18) are flush with the nuts (2).
NOTE: Out-of-flush tolerance J2 is:
- 0 +0 mm or -0.5 mm (0.0000 +0.0000 in. or -0.0197 in.) for the round section seals
- 0 +0 mm or -1 mm (0.0000 +0.0000 in. or -0.0394 in.) for the square section seals.
NOTE: The negative value of out-of-flush tolerance J2 is related to the fastener intrusion in the nut.
