1. Open the pressure plate holder by pushing

2. Hold the pressure plate between the thumb
and forefinger and lift it up as far as it will go.
3. Pull the pressure plate straight out toward
you. Wipe it gently with a soft cloth, and replace
it by reversing the above procedure.
Before cleaning the aperture plate, remove the
pressure plate as described above. Then inspect
the aperture closely to make sure that the film
pulling claws are recessed and out of the way.
The claws
are two tiny pins which
become
visible in the aperture as you turn the film thread-
ing knob. If they are visible, turn the knob until
they disappear; then clean the aperture gate.
Replace the pressure plate, and close the pres-
sure plate holder.
To clean the projection lens, first remove it by
pulling it forward out of its mount. Wipe both
