Chapter 5—Preventive Maintenance

5.1.2.Cleaning the Projector Lens

Under normal environmental circumstances, clean lenses only when accumulated dust makes the picture fuzzy. Clean the projection lenses with a camel hair brush to remove dust or use dry air to blow dust off. Dampen a lint free cloth with lens cleaning fluid (do not use window cleaner or alcohol) and wipe the lens clean in a continuous circular pattern from the center of the lens to the edge.

Only clean lens when absolutely necessary— too frequent cleaning can destroy the lens coating.

5.1.3.Air Filters

Periodically inspect the air filters at the bottom and rear of the HJT Model 100 Projector for heavy accumulation of dirt and debris that may inhibit proper air circulation. The air filters can be cleaned with air guns, or submerged into a mild soap bath, being careful to thoroughly dry the filter before use.
