During assembly, the shutter springs can pop out of place. Always wear
protective eyewear during this procedure.
See Figure 10. Stand the top and bottom front barrel castings (1 and 2) upright
with the shutter end of the castings toward the bottom.
The top front barrel casting (1) contains the iris slot.
Slide the bottom divider plate (4) into its place in the bottom casting (2). The
dimples on the divider plate must point down.
The bottom divider plate (4) has four dimples punched into the surface; the top
plate (6) has none. The middle divider plates (5) are noticeably thinner-gauge
metal than the other two.
The notches on the divider plates must fit against the flanges in the casting so the
plates do not move.
Divider plate edges are sharp. Handle with caution.
With the bottom barrel casting (2) to your left, place one shutter blade (3) on top
of dimpled divider plate (4) handle facing outward, up and down. (See
Install shutter blades with the rounded side facing up toward the front of the
casting.
Place the middle gate plate (5) on top of the shutter blade.
Place another shutter blade (3) on top of the divider plate and then place the
other divider plate on top.
Place the two shutter blades on top of the divider. Pull the blade and plate
assembly slightly forward to allow the handle to slip through the slot in the bottom
casting.
Place the top divider plate (6) on top of the two shutter blades.
Make sure no shutter assembly components are under the pattern holder guides.
With both front barrel castings still standing upright, join the two halves, sliding
the handle of the top shutter blade through the slot in the top front barrel casting
(1).
Connect the halves of the gate assembly using two PHMS screws (8). Hand
tighten only (25 inch pounds).
The tops of the two front barrel castings must be even. Adjust as necessary before
completely tightening the screws. Failure to do this could interfere with the barrel
rotation.
