OPERATOR CLEANING INSTRUCTIONS
1. The optical system and the window are coated with anti-reflection material. When cleaning
the glass surfaces, first blow away any dirt and dust. Fingerprints and lubricants can be wiped
off with lens tissue or a soft cotton cloth, moistened with lens cleaning fluid or glass cleaner sold
in any camera store. Never clean the glass surface with a dry cloth or paper towel; always
dampen the glass surfaces prior to cleaning.
2. No maintenance is needed on the sight’s surface, except to occasionally wipe off with a soft
cloth. Use only a water-based cleaner such as glass cleaner, ammonia, or soap and water.
Never use any solvent-type cleaner such as alcohol or acetone. Do not use gun cleaner to
clean or lubricate the Reflex Sight.
3. All moving parts of the sight are permanently lubricated. Do not try to lubricate them.
4. Never disassemble the sight’s optical assembly! The optical cavity is purged, nitrogen filled,
and sealed to achieve fog proof performance. Disassembly will void the warranty and
damage the sight.
