SECTION 8 − MAINTENANCE
. Never use solvents or abrasive cleaning detergents. Do not immerse the lens assembly in water.
The helmet requires little maintenance. However, for best performance clean
after each use. Using a soft cloth dampened with a mild soap and water solution,
wipe the cover lenses clean. Allow to air dry. Occasionally, the filter lens and
sensors should be cleaned by gently wiping with a soft, dry cloth.
