B. EXA assembly.
1. Mechanism insertion.
As under disassembly of camera A.4, but in reverse order. Check for correct functioning.
2. Close left side.
As under disassembly of camera A.3, but in reverse order. Check for correct functioning.

4
3. Close right side.
As under disassembly of camera A.2, but in reverse order. Check for correct functioning.
4. Check and adjust the distance between the lens mount and the film plane.
Check along the film-path with a Meßuhr [means dial-gauge - should be depth-gauge, surely?].
The distance between the lens-mount and the film-guides must be 44.72 ± 0.01mm. The film-
path should be set accordingly [presumably by means of shims under the mount. There is no
way of setting the film-path itself].
5. Check and adjust the mirror position.
(Collimator is set to infinity).
a) Example 1:
The greatest sharpness lies before the infinity stop of the lens: hold the mirror retaining
spring 300.23 U 5 with the mirror hook (see diagram Fig. 1). Bend the chamfered rivet on
the mirror retaining spring downwards, until the greatest sharpness is obtained at the infinity
mark of the lens.
b) Example 2:
The greatest sharpness is not yet obtained at the infinity stop of the lens (i.e. the point of
sharpest focus would lie beyond the infinity stop): hook the mirror retaining spring (with a
screwdriver or knife) behind the chamfered rivet and bend it into the mirror chamber until
the greatest sharpness is obtained at the infinity mark on the lens.

BB. Assembly of camera EXA I/63.
1. Mechanism insertion.
As under disassembly of camera AA.3, but in reverse order. Check for correct functioning.
2. Top-plate 350.21 U 1 fitting.
As under disassembly of camera AA.2, but in reverse order. Check for correct functioning.
3. Check and adjust the distance between the lens mount and the film plane.
As under assembly of camera B.4.
4. Check and adjust the mirror position.
As under assembly of camera B.5.
C. Elimination of certain faults.
1. Shutter flap 350.04 U 5 falls back. [i.e. mirror is not caught by retaining spring]
a) Open right side (EXA) or remove top-plate 350.21 U 1 (EXA I/63).
As under camera disassembly A.2 or AA.2.
b) Bend apart the adjustable slot on the mirror cocking lever 350.04 U 2 (EXA), 350.04 U 7
(EXA I/63), see Fig. 2, until cocking stroke suffices and shutter flap goes past the retaining
spring 300.23 U 5 by about 0.5mm.
If the shutter flap falls back despite the adjustment of step b), then the mirror retaining spring
does not lie correctly in place in contact with the shutter release lever 350.04-8.
c) Remove the mechanism.
As under camera disassembly A.4 or AA.3.
d) Give the mirror retaining spring a bias [i.e. bend it down], being mindful of the mirror
setting.

2. Shutter does not engage (Shutter flap 350.04 U 5 runs closed) [i.e. second part of shutter
does not catch and runs with mirror]
Dismantle camera, as under Disassembly of Camera A.1 - A.4, or AA.1 - AA.3, and do as
described in Elimination of certain faults C.1 - Shutter flap falls back.
a) Verify the functioning of all the shutter levers together (i.e. levers must slide well and mirror
retaining spring must rest against the release lever 350.04-8). If Point a) is ensured, without
the fault being rectified, the shutter must be adjusted and/or readjusted.
b) Set the timing lever 350.04 U 3 (EXA) or 350.21 U 3 (EXAI/63) to B. Cock the shutter.
c) Restraining the first shutter flap with a finger, fire the shutter and let the first shutter flap run
slowly. Do not grasp the mirror. The release of the first shutter flap must occur about 2mm
before the shutter release lever stop. The release point is varied by the bend at the
adjustment slot in the shutter release lever.
d) Allowing the shutter release lever to move slowly outwards, the release of the second part of
the shutter flap must occur about 2mm before the edge of the plate [the plate above?]. The
release point is adjusted by bending the release nose of the shutter release lever [the lower
end].
e) Cock the shutter.
f) Release the shutter and pay attention to the second shutter flap. This must move in the
direction of the first shutter flap by about one millimetre before being stopped by release
lever 350.04-12 [the one at the bottom corner]. If this does not occur, the release lever must
be corrected [gerichtet] [i.e. bend the part turned inwards?].
g) Set the exposure time lever to 1/50 sec or 1/60 sec. Cock the shutter.
h) Holding the first shutter flap with a finger, fire the shutter and let the first shutter flap run
slowly, the release pin for the first shutter flap (see Fig.3) must now run towards the point
on the secondary lever on the exposure time lever. If this does not occur, the Anschlag
[?tab/stop?] on the secondary lever must be adjusted.

7
i) Set the exposure time lever to 1/150 sec or 1/175 sec. Cock the shutter.
j) Holding the first shutter flap with a finger, fire the shutter and let the first shutter flap run
slowly. The release pin for the shutter flap (see Fig.4), must now release the second shutter
flap in the indicated position. If this does not occur, the trip lever 350.04-13 [the long
vertical lever] must be bent at its lower end.
k) Control of the release at all shutter speeds.
The release of the second shutter flap must occur as described in Point j) at all shutter
speeds. If readjustment at the 1/50 sec (or 1/60 sec) or 1/25 sec (or 1/30 sec) should still be
necessary, then this is to be made at the curve of the trip lever over the half-round recess.
l) Check the shutter with a shutter time measuring device.
Example 1:
Shutter too light: Reduce the tension of the first shutter flap, or increase the tension of the
second shutter flap. [HOW?????????????????????????????????]
Example 2:
Shutter too dark: Increase the tension of the first shutter flap, or reduce the tension of the
second shutter flap. [HOW?????????????????????????????????]
The options of the shutter time adjustment stated under l) are used alternatively by the
camera mechanic.

3. Mirror 300.21-53 replacement.
a) Remove the back 350.02 (EXA) or 370.20 (EXA I/63).
b) Place the camera front uppermost.
c) Remove the four lens-mount fixing screws M1.7 x 6.5 DIN 91 (EXA) or M1.7 x 6 DIN 63
(EXA I/63). Remove the lens-mount (noting any shims 300.21-52/1).
d) Guide the front edge of the shutter flap to the level of the gap in the round opening in the
outer casing. Bend outwards both the retaining tabs (left and right) for the mirror.
e) Slide the mirror out.
f) Insert the new mirror and bend the retaining tabs back inwards.
g) Replace the lens mount.
h) Check/adjust the lens mount to film path distance.
See under assembly of camera B4.
i) Check/adjust the mirror position.
See under assembly of camera B5.
4. Frame-counter failure.
EXA
a) Open right side, described in Disassembly of Camera A.2.
b) Cock and fire the shutter, observing the spring for the ratchet-lever 350.07-17.
c) Bend the spring for the ratchet-lever, near the mounting of the frame-counter disc 350.07-
21, so it engages with the teeth.
d) Close the right side. As in Disassembly of Camera A.2, but in reverse order.
e) Check the operation.

9
5. Synchronisation failure.
Adjusting the flash synchronisation.
EXA
Dismantle the camera, as under Camera Disassembly A.1 - A.4.
a) Set the exposure time lever to the 1/25 sec position and cock the shutter.
b) Holding the leading edge of the shutter flap with a finger, fire the shutter and let the leading
edge of the shutter flap run slowly. The X-contact must fire near the position shown in Fig.
5, and the F-contact near the position shown in Fig. 6. If they do not do so, the contact
spring must be bent at the flash contact accordingly.
c) Reassemble the camera, see Assembly of Camera B.1 - B.5.
Adjusting the flash synchronisation.
EXA I/63
Note:
The setting of both flash contacts (X and F) depends on the linkage between the time setting
disc 350.21 U 3 and the contact disc 350.22-13 on insulating-part I 350.22 U 4. Because of
this, setting the shutter times causes at the same time a changeover of the contacts.
The X-synchronisation takes place at shutter speeds of 1/60 sec and B.
The F-synchronisation will operate at shutter speeds of 1/175 sec, 1/125 sec and 1/30 sec.

10
Adjusting the insulating-part I. [the insulating block under the time-setting disc]
Dismantle the camera, as under Disassembly of Camera AA.1 - AA.2.
aa) At the F-synchronisation the contact spring of insulating-part I must touch the contact pin
(where the connection for the coupling wire 350.22-11 is). If necessary bend the contact
spring accordingly.
bb) Replace the top-plate 350.21 U 1, as under assembly of camera BB.1 - BB.2.
Adjusting the insulating-part II. [the block with the flash contacts on the right below the
wind mechanism]
Dismantle the camera, as under Disassembly of Camera AA.1 - AA.3. Check the F-contact:
cc) Set the time setting disc to 1/30 sec and cock the shutter.
dd) Restrain the shutter flap, release the shutter and let the shutter flap run slowly; the F-
contact must fire as shown in Fig. 7. If this does not occur, the contact spring for insulating-
part II must be bent accordingly.

11
Checking the X-contact.
ee) Set the time setting disc to 1/60 sec and cock the shutter.
ff) Hold [restrain?] the shutter flap, release the shutter and let the shutter flap run slowly; the
X-contact must fire as shown in Fig. 8. If this does not occur, the contact spring for
insulating-part II must be bent accordingly.
gg) Reassemble the camera, see Assembly of Camera BB.1 - BB.4.
6. Checking the film transport.
NB. Only use a faultless cartridge! When spools for daylight loading are used, these may only
be inserted in cassette cases of the same manufacturer. With film transport from cassette to
cassette, special attention must be paid to the wind-on cassette. If necessary the sliding surface
of the spool may be lightly rubbed with paraffin. The spool must slide easily into the case and
must not be at an angle. All these points being in order, the checking of the camera can begin.
Checking the friction-bush 300.15 U 3 (EXA) or 370.03 U 11 (EXA I/63).
a) Remove the rear cover 350.02 (EXA) or 370.20 (EXA I/63) and the take-up spool 350.10
(EXA) or 370.09 (EXA I/63).
b) Hold the friction bush with the left hand, and at the same time slowly cock the shutter. The
friction bush must give uniform resistance and not scrape, catch or run very much out of
true.
c) A faulty friction bush is to be removed, cleaned and re-lubricated.
