1. Air Cylinder Replacement
(1) Close hand valve at the lower right of main body.
(2) Remove the 2 M6 SEMS cap screws to separate support angle from main body.
(3) Remove ATC and M3 SEMS cap screw and remove air cylinder (Detach φ4 air tube).
(4) Attach ATC OPN & CLS sensor assemblies straight onto the new air cylinder.

When slide plate is pressed together as shown above, set distance from ATC base to ATC angle
at 6.7±0.5mm by adjusting ATC joint with cylinder accessory nut. At this time coat the threads
with Locktite 242.

Note 1: Be sure there is rubber in the tip of the sensor fastening screw.
Note 2: Tighten fastening screw to torque 1~2kgf•cm.

(6) Connect φ4 air cylinder. Open hand valve bit by bit until air comes out and connect at location (B) in
Fig. 7 - 1 - 1. Connect another at location (A).
(7) Follow (2) in reverse sequence to connect (only tighten screw provisionally).
(8) Set ATC offset boss assy (jig) in the 2 holes as shown below.
While looking at the live image of the OCC camera, move head with HOD until one of the ATC is
nearly centered in the CRT.

Next, move HOD along X-axis (Do not move in Y-axis) until the other offset boss can be seen.
Loosen screws (a) & (b) and move ATC with ATC support angle until the boss is nearly centered in
the CRT.
Repeat this procedure with the 2 bosses until Y-axis displacement is to within 0.1mm at both ends
and then tighten screws (a) & (b).
Since camera aperture is 6.3mm and boss diameter is 2.5mm, a visual judgement must be made.
(9) Reenter MS parameters of ATC offset.
