The helmet and ADF must be checked regularly. Defective equipment should not
be used. Parts that are broken, missing, worn, distorted or contaminated, should be
replaced immediately.
a. Inspect lenses frequently. Immediately replace any scratched, cracked, or pitted
lenses as they may impair visibility and reduce protection.
b. Inspect Helmet Shell and Harness Assembly frequently. Replace any damaged or
worn components immediately.
c. Keep the Sensors and the Solar Panel clean at all times. When cleaning the Welding
Helmet or Filter Lens do not use solvents or abrasive cleaning agents. Clean with a
soft cloth after use.
