1.124   Pawl Tension 
Check tension of 084 pawl.  It must have enough tension to 
engage the 082 latch every time (Min. 7 grams, Max. 15 grams).  
If tension is weak, movement must be removed and tension 
adjusted by turning 089-090 stud and spring with pliers, then 
restaking stud to hold it in new position.  If spring is 
damaged beyond repair, remove 089-090 stud and spring and 
replace with new one, stake in lightly, adjust to proper 
tension, and stake or rivet in place.  This requires removing 
movement from camera.  (See section 23.100 and 24.100) 
 
1.200   Shutter sticks open when release in bulb. 
Remove bottom and back. 
1.210   Sticky Shutter Blade 
It is very seldom that you will find a sticky shutter blade above 
camera #1200.  However, this should be checked for first by 
pulling shutters back and forth with wooden or plastic stick.  If 
shutters are sticky, remove front, change shutter blades, and 
reassemble and install front according to instruction.  (see 
section 22.000) 
1.220   Weak Release Lever Spring 
The 212 release lever sprint may be weak and there may be a 
little extra friction in movement.  Tighten spring by cutting off 
three or so loops from the lever end, and lubricate in the 
following places: 083 latch and 506 floating lever where they 
engage, and edge of 109, which is beneath 519 plate assembly, 506 
floating lever and 096 movement plate. 
1.230   Ratchet 
(See section 1.110) 
 
1.300   Shutter will not open 
This will cause blank (black) spaces on film.  Remove bottom and 
back according to instructions. 
1.310   Ratchet 
Make test and repair as described in section 1.110 
1.320   Pawl Engagement 
The shutter blade must pick up the 083 secondary pawl.  If ear is 
not correctly adjusted, bend to insure pick up.  If ear is 
broken, remove front, replace, reassemble, and reinstall front.  
(See section 22.200) 
1.330   Tight Latch 
Check to be sure the 082 latch is free.  If it is tight, press 
down very carefully on 082 latch to give end play between 096 
movement plate and 082 latch, then apply “DAG” to 082 latch.  If 
this does not free 082 latch, the tightness may be between the 
082 latch and 088 latch stud, in which case the movement must be 
removed and the 088 stud, in which case the movement must be 
removed and the 088 stud replaced, then place the movement in 
camera according to instructions.  (See sections 23.100 and 
23.200)
