Focus Lens Inspection and Cleaning (as necessary)
1.
Remove the Thumbscrew from the side of the Focus Lens Holder. Hold the Focus
Lens Holder while removing the Thumbscrew so the Focus Lens Holder does not
fall.

2. Inspect the Focus Lens while it remains in the Focus Lens Holder by holding it up
to a light and looking through it. If the Focus Lens looks visibly clean, do not clean
it, simply re-install it to the Focus Carriage by proceeding to Step 8.
3. To clean the Focus Lens while it is still in the Holder, hold it on a 45 degree angle
and flood it with a few squirts from the Lens Cleaner bottle and let it drip off. With
a cotton swab, gently dry off any remaining solution by rolling the cotton swab
across the Focus Lens.
DO NOT press down hard on the Focus Lens or slide the
cotton swab across the Focus Lens as this may scratch it. Only roll the cotton
swab across it to dry it off. If the inside of the Focus Lens is dirty, clean it the
same way. If the Focus Lens does not clean easily or needs to be replaced, it will
need to be removed from the Lens Holder so proceed to the next step. If the
Focus Lens is clean proceed to Step 8.
4. Place a soft cloth on a table to prevent the Focus Lens from breaking in the event
that you drop it. Place a piece of Lens Tissue on top of a soft cloth. Sit down in
front of a table and remove the Focus Lens from the Focus Lens Holder by holding
it in one hand and a unscrewing the Retainer with the other hand. Carefully turn
the Focus Lens Holder upside down onto a piece Lens Tissue so that Focus Lens
and Nylon Spacers drop out onto the Lens Tissue.
5. Inspect the Nylon Spacers and clean them if necessary with a swab or paper towel
and Lens Cleaner. Re-install the bottom Nylon Spacer into the Focus Lens Holder.
6. Flood the Focus Lens with Lens Cleaner on one side, flip it over and flood the
other side. By using a fresh sheet of Lens Tissue, pick up the Focus Lens and
gently dry both sides. Keep your hands close to the soft cloth in case you drop the
Focus Lens.
DO NOT touch the Focus Lens with your bare hands.
