(b)
Disengage the roller (16) from the fork end (15).
(c)
Push the fork end (15) carefully into the switch housing with a suitable tool until you feel resistance and hold.
(d)
Turn the fork end (15) to 90 degrees and release it.
(e)
Put the roller (16) in the fork end (15) and install the bolt
(14) and the nut (17).
(f)
Tighten the nut (17) correctly.
(3)
Set the adjustment nut (7) in the correct position on the limit switch (6) as follows:
(a) Measure the distance between the end of the roller (16) and the contact surface of the adjustment nut (7).
NOTE : The necessary distance is 22.0 mm (0.8661 in.)
____

E. Adjustment of the Limit Switch 2508MJ or 2509MJ
(1)
Remove electrical connector (2) from the receptacle (1) and connect the probes of the continuity tester to the related pins of the connector (2).
(2)
Find the correct switch point of the limit switch (6) as follows:
(a)
Set the manual lever of the door sill latches in the forward direction until the continuity tester shows an open circuit.
(b)
