o replace the FH Flyer focusing lens, perform the following steps:
1 If the focusing lens assembly has a dowel pin on its inside face, refer to Figure 7-2 and position
the
lens mount so that the dowel pin lines up with the non-threaded dowel pin hole in Flyer’s bottom
plate.

2 Insert the dowel pin into the dowel pin hole, then rotate the lens slightly as required so the screw
holes align with the threaded holes in Flyer’s bottom plate.
If the lens mount does not have a dowel pin, simply line up the screw holes in the lens mount with
the threaded holes in Flyer’s bottom plate.
3 Hold the lens in position, then insert and loosely fasten the three 8–32 × 3/8" Allen cap screws.
4 While carefully tightening the three cap screws, inspect the lens mount assembly around its circum-
ference and verify that the lens mount ts ush against the bottom plate.
Note: If the lens mount assembly does not t ush against the bottom plate, remove the lens and re-
check the alignment and t of the dowel pin.
