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 HWS®.
3. All moving parts of the sight are permanently lubricated with the exception of the quick release
lever. If audible sounds are generated when opening/closing lever, add a drop of lubricant to lever
assembly. Do not try to lubricate any other moving part.
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 dam-
age the sight.
