f. PINION COUPLER LEVER (E10) AND COUPLER LEVER (C15).
After fixing the mirror housing assembly (0B02) and (E10) to the body proper, the following adjustment
has to be performed:
(1) Adjustment of (E10)
The "A" part of (E10), before shutter rocking, is supposed to be in parallel with the groove of the
body proper checked by the coupler gear stud (E46) of the coupler gear (E18) as shown in Diagram
17-A; and the position of (E46) is to be determined by the half-moon shaped slow speed lever
actuator stud (E45). (Refer to Diagram 19.) When the shutter is cocked, the "B" part of (E10) should
be so positioned as to slightly pass the brink of the groove of the body proper. In the event this
position is found unattainable, bend the "C" part of (E10) with pliers for necessary adjustment.

(2) Adjustment of (C15)
Before the shutter is wound, the tip of the mirror actuator lever, bottom (B19), is located close to (E18).
In the course of winding the shutter, it slides along the groove of the body proper, forced by the tip of
(C15). When (B19) is positioned closest to the back of the body proper, the gap between (B19) and
(E10) should be adjusted to be within 0.3-0.5 mm. This adjustment is to be performed by bending the
"D" part of (C15) with a pair of flat-nose pliers.
(Diagram l7-B)
NOTE: In case (C15) is bent too much, (B19) will collide, during the course of winding, against the back
of the body proper, resulting in heavy winding or failure in cocking.

2. Adjustment of Shutter Exposure Timing.
After installing the speed dial (E23), the shutter exposure time is to be adjusted in the following order.
However, covers such as (A03). (A04) and (A05) should be left unassembled.
