setting gear assembly (figure 7). The shutter setting gear is keyed to the shutter setting gear shaft assembly (figure 1) , which extends through the mechanism plate. Underneath the mechanism plate the roller on the shaft makes contact with the shutter setting blade assembly and as the shaft is rotated , forces the shutter setting blade assembly over to the right and cocks the shutter.
on the left end of the safety lever assembly into the slot. The safety control driving shaft assembly will stop turning unless it is forced. With film in the camera, the top edge of the back makes contact with the safety latch, holding it in, and the safety control driving shaft is turned by the film as the film is drawn past by the winding key knob.
Remove the parallax frame assembly and the eyelet lens assembly (figure 5) by removing the two range finder eyelet frame screws. Remove the range finder plate screw (figure 6). Unhook the cam follower spring (figure 14) from the range finder cam assem~Remove the cam follower screw and carefully lift off the cam follower assembly. Remove the focus scale bracket by removing the two holding screws.
Figure 16 CAUTION: Make sure the focusing tube assembly is retracted. H it is extended beyond the infinity setting, the stud on the range finder actuating lever assembly will go on the camera on the wrong side of the range finder adjusting screw (figure 1). Turn the counter dial assembly (figure 5) to any number except "0" in order to move the end of the safety control stop pawl (figure 6) away from the safety control cam complete.
_ it on the new style cam follower assembly, the range finder may be moved out of adjustment. For adjustments to the range finder see page 16 . Set the range finder on infinity by looking at an object at least 200 feet away. Then replace the focusing dial on the pinion with the infinity indication facing toward the front of the camera. Secure the dial in position with the holding screw. Set the direct view finder cover on the range finder plate and fasten it with the four retaining screws.
which projects toward the trigger button end of the mechanism plate. If the shutter setting blade assembly cannot be straightened so that it works freely, replace it, fitting the pin on the top of the new assembly through the hole in the shutter setting lever light guard (figure 13). Replace the three shutter setting blade stud nuts, the range finder actuating lever link washer, and the range finder actuating lever link nut.
ADJUSTING SYNCHRONIZA TION WITH THE SPRING ON THE SAFETY LEVERASSEMBLY If it is not possible to obtain sufficient adjustment of the synchronization by moving the right shutter operating lever lug, it is necessary to adjust the black spring on the safety lever assembly. This adjustment can only be made with the range finder plate removed from the camera.
OPTICAL ADJUSTMENTS TO RANGE FINDER. NOTE: It is preferable to correct optical defects (figure 21) in the range finder system in the order named . ONE FIELD IS SMALlE R THAN THE OTHER. This condition is due to tilting of the erecting prism forward or backward, usually caused by a severe jar to the camera . The focus of one or both fields may also be affected. Remove the two range finder eyelet frame screws (figure 5) and the parallax frame assembly .
NOTE: After an adjustment has been made to correct tipped vertical lines, it will probably be necessary to correct the halving also . EITHER FIELD OUT OF FOCUS . The focus of each field is controlled by the position of its objective lens mountassembly . The lefthand lens mount assembly controls the lower (stationary) field, while the right- hand lens mount assembly controls the upper (movable) field. If it is necessary to adjust the right-hand lens mount, the focusingdialmut be removed.
BACK COMPLETE (See figure 12). Place the two hinge latches in position, one at each end of the back, and fasten them with the two hinge screws. Place the two hinge pin springs and the four hinge pins in position and hold them in place with the hinge latches at either end of the back. The hinge pins must be turned so that the holes are in position to receive th€ hinge grips. Using adhesive tape to protect the finish on the hinges, force the four hinge grips into place with a pair of blunt-nosed pliers .
FOCUSING TUBE ASSEMBLY. On each side of the opening into which the focusing tube assembly (figure 9) is to fit, the outside edge of the flange projects about 1/ 16 inch for a distance of about 1 1/ 2 inches . Coat the inside of the flange at these pOints with black wood lacquer dope. Remove the inside focusing tube from the outside focusing tube. Turn back the focusing tube insert until it fits tightly against the focusing tube flange with the stop stud on the bottom.
I the key complete with the flat side of the key cam toward the left end of the camera. Replace the safety control cam complete on the key post with the gear on the bottom meshed with the safety control idler gear (figure 7). Replace the safety lever assembly (figure 13) with the two prongs on the left end above and below the gear on the safety control cam complete.
the end of the lever a little where it comes in contact with the stud on the safety lever assembly. If the parallax frame assembly (figure 5) and the range finder eyelet lens assembly were removed from the range finder plate in disassembly, replace them and fasten with the two range finder eyelet frame screws. The eyelet lens assembly should go on first with the frame toward the rear; make sure that it is straight and that itis pushed as far toward the front of the camera as it will go.
lax frame assembly (figure 2) is operating properly without binding on the view finder cover. The par-allax frame assembly can be seen by aiming the view finder at a light and looking into it rather than through it. If the parallax frame assembly is functioning correctly, it will be seen to move smoothly downward as the focusing tube assembly is moved ou~ toward the 3 1/2-foot position.
CAUSE TROUBLE Camera is jammed. The safety control driving shaft assembly (figure 11) has been turned manually without first turning the winding key knob. (The camera usually jams on the third or fourth cycle.) See page 8. REMEDY Set the counter dial on "1." Rack the focusingtube assembly all the way in. Press the trigger button down as far as possible and hold it down while turning the winding key knob until a definite click is heard.
- TROUBLE CAUSE Winding key knob does not lock with counter dial on a number other than "0." The safety lever sring (figure 13) is weak or bro en. Disassemble the camera down to the mechanism plate and replace the safety lever spring. Shutter trips when shutter setting lever is released. Tension on the guide lug spring (figure 10) is too high . Stretch the guide lug spring slightly. Film winds too hard. The key complete (figure 4) is binding on the counter dial housing complete.
TROUBLE CAUSE Focusing tube works too freely. The upper guide rod (figure 1) has been turned. -- Turn the upper guide rod by means of the screwdriver slot at the back end of the rod until the focusing tube does not operate so easily. Refer to page 19. Spacing between exposures is too great or too small. The winding key knob has been forced and the prongs on the left end of the safety lever assembly (figure 13) are bent.
