Note:
19°, 26° and 50° aspheric lenses have painted dots to orient the lens in the tube.
Install the lens with the painted dot facing the front of the tube. Seat the lens in the
support pads so the dot remains visible.
Step 7:Invert the right lens casting (2) and hold it above the left lens casting (1).Fit the
clip (9) and spring (10) into the right lens casting. Gently place the right lens
casting onto the left lens casting, making sure that the 1/4-20 hex nut and
retaining clip assembly stay properly seated. Make sure the lens stays straight
by looking into the lens holder. The top edge of the lens should seat properly in
the support pads.
Step 8:Install the PHMS screws (11) in four locations with Ny-lok nuts (12). The PHMS
screw location on the bottom of the colorframe holder is threaded and does not
require a Ny-lok nut. Hold the nuts tight against the casting and torque the screws
to 25 inch pounds.
Step 9:Install the eight bushing guides (3). Point the narrow tab on the bottom toward
the back of the casting; point the square tab toward the front. Squeeze the guides
slightly so they bend in the middle then snap into place. Make sure the rounded
side of the guide faces outward from the tube.

Cleaning 19°, 26°, 36°, and 50° glass lenses
Step 1:Dampen a clean, lint-free cloth with vinegar or household ammonia. You may
use water, but it leave spots. You can remove the spots by polishing the lens
gently with a clean, dry cloth.
WARNING:
Step 2:Starting from the center, gently wipe the lens.
Never use glass and window cleaner or any abrasive material to clean the
lens. Glass and window cleaners will stain the lens surface. Abrasive
materials (such as steel wool) will damage the surface of the lens.
