Lens Tube: 14° 23
Lens Markings and Positions: 14°
The lenses are colour-coded for identification. The rear lens has two brown dots and the front
lens has one brown dot. The lens positions are colour-coded within the lens casting to match
the coloured dots on the lenses (see
Figure 22
).
Assembling the Lens Tube: 14°
Tools Required:
• #2 Phillips head screwdriver
1: Place lens tube assembly faceup on your work surface.
2: Install the eight bushing guides (7). Point the narrow tab on the bottom toward the back of
housing; point the square tab toward the front. Squeeze the guides slightly so that they end in
the middle, and then snap them into place. Make sure that the rounded side of the guide faces
outward from the tube.
3: Install the front lens (10) in the tube using required bumpers (9), screws (12), nuts (11), and
washers (13) as shown in
Figure 21
. The coloured dot on the lens should face towards the front.
Cleaning the Glass Lenses: 14°
1: Remove dust with a blast of oil-free air or wipe with a clean, lint-free cloth. Isopropyl alcohol,
distilled water, or a 50%-50% mixture of each can be used to clean the glass surface.
2: If necessary, remove the front lens to access the front surface of the rear lens for cleaning.
Remove the four screws (12), nuts (11), washers (13), and bumpers (9), and gently lift out the
front lens as shown in
Figure 21
. Reassemble in reverse order.
WARNING:
Do not use ammonia-based or other harsh commercial cleaners. Clean lens
only as directed.
Commercially available glass cleaning agents should be avoided as they may
contain ammonia, other harsh chemical detergents or abrasive agents. These
cleaners may damage the glass surface and the Anti-Reflective coatings. Do
not immerse or soak the glass in any cleaning solution.
