Step 1: Remove the beam focus knob along with retainer bolt and collar from the barrel (see
Figure 1). Remove the lens tube from the barrel.

Cleaning 5° and 10° polymer lenses

To quickly clean the lenses, remove dust with a blast of oil-free air. If this is not sufficient, follow
these steps.
WARNING:
Do not use ammonia-based or other harsh commercial cleaners. Clean
lenses and reflector 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.
Note:
To clean the inside of lenses, it is necessary to remove the lenses from the lens
tube for cleaning. Instruction for removing the lens can be found in the Source
Four Assembly Guide available for download at our website:

CAUTION:
Handle polymer lenses by their edges only. Never rub anything dry on a polymer
lens.
