Gate Housing assembly
Source Four Zoom Assembly Guide
Tools required: Phillips head screwdriver.
1. Stand the top and bottom gate barrel castings (1 and 2) upright
with the shutter openings down.
Note: The top gate barrel casting contains the iris slot.
2. Slide in the bottom divider plate (4). The dimples on the divider
plate must point down.
Note: The notches on the divider plates must fit snugly against
the flanges in the casting so the plates do not move.
Warning: Divider plate edges are sharp. Handle with caution!
3. With the bottom barrel to your left, place one shutter blade (3)
on top of dimple plate (4), handle facing outward, up and down.
Note: Install shutter blades with the rounded side facing up
toward the front of the casting.
4. Place a divider plate (5) on top of the shutter blade.
5. Place another shutter blade on top of the divider plate. Then
place another divider plate on top.
6. 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.
7. Place the top divider plate (6) on top of the two shutter blades.
Note: Make sure no shutter assembly components are under
the pattern holder guides.
8. With both gate barrel castings still standing upright, join the two
halves, sliding the handle of the top shutter blade through the
slot in the top gate barrel casting (1).
9. Connect the halves of the gate assembly together using the two
PHMS screws (8).
Note: The tops of the two gate barrel castings must be even.
Adjust as necessary before completely tightening the nuts and
screws. Failure to do this could interfere with the barrel rotation.
10. Turn the gate barrel assembly over so that the narrower end is
on your work surface.
11. Install the four shutter springs (7) between the four dimples in
the shutter plate and the tabs in the lip of the casting.
Note: Install the springs at the joints in the castings on either of
the tabs at the joint.
Caution: During assembly, the shutter springs can pop out of
place. Always wear protective eyewear during this procedure.
12. Place iris slot cover (9) over the iris slot. Use two screws (10) to
secure the cover.
