Out shooting yesterday, and the ... I believe the delayed action button??, that in the past I could push and move to open the shutter to focus, will not move. Any ideas...

hey peter
it would help to know what lens as there can be some differents
to shutter size & tips of flash pluge as to how its all set up

BUT you may just need a good cleaning

Ah ... didn't give all of it ..

Graflex Optar f~4.7 135mm

hey peter
there are two shutter #! fully synchronized #2 (X) BUT they work the same

For convenice in opening the shutter for ground glass focusing, the Press Focus Lever at the right side (just up from the flash pluge) of the shutter may be use. Cock the shutter in the normal way & depress the Press Focus Liver in until the shutteris opened. To close the blades agean, by moving the Press Focus Liver Outward & upward. DOIZ NOT TRIP IT TO CLOSE THE BLADES

if this don't its time to do some Cleaning
flush it out with liter flud & blowdry

OH PS you do need to take the lens off first!!

Lighter fluid destroys plastic and rubber parts used in some shutters.
The Graphex shutters use plastic and rubber insulators in the flash sync.

I, as well as many others CLA (clean, lube, adjust) these shutters.

If you want to try it yourself follow

Graphex X shutters will have a simpler flash sync than the one in the service manual.

Da... forgot, to cock shutter... works fine

thanks guys
