7-2 Adjusting the AC Solenoid
1.
Loosen the 3 socket cap screws (M4x12)
holding the spring bracket in place. (Only
loosen the screws sufficiently so that the
screw heads are in contact with the bracket,
but the bracket can move up and down.)
Adjust the spring tension so that the adjuster
rail drops fully. Retighten the 3 socket cap
screws (M4x12).
2.
Loosen the locking nut (M6) and slacken the pozi head screw (M6x40)
used for adjusting solenoid bracket (A).
3.
Loosen the 4 socket cap screws (M5x12) holding solenoid bracket (A) in
place. (Only loosen the screws sufficiently so that the screw heads are in
contact with the bracket, but the bracket can move up and down.)
4.
Turn the power to the machine ON.
5.
Select the rail test in Test Mode 
(see section 6-3)
 and press the service
switch once, activating the AC solenoid. (Adjuster rail connects with the
main rail.)
6.
Adjust the solenoid bracket (A) up and down with the pozi head screw
(M6x40) so that the adjuster rail and main rail are in solid contact but
without any buzzing from the solenoid. Re-tighten the 4 socket cap screws
(M5x12) that hold solenoid bracket (A) in place.
7.
Press the service button twice, reactivating the AC solenoid, and confirm
that there is no change in the contact condition of the adjuster rail and
main rail and the solenoid does not buzz. Tighten the locking nut (M6)
making sure that the adjustment screw does not move. Release and
energise the solenoid 2 - 3 times. If a change does occur, repeat from
step 6 and readjust the solenoid bracket (A).
9.
Slide the test switch OFF to return to game mode.
