WARNING

•Carefully inspect the complete Speedglas 9100 welding shield assembly before each use. Check for cracks in the shield and look for light leaks. Cracked, pitted or scratched filter glass or protection plates reduce vision and can seriously impair protection. All damaged components should be replaced immediately.

•To avoid damage to the product do not use solvents for cleaning. Clean the welding filter and protection plates with a lint-free tissue or cloth. Clean the welding shield with a mild detergent and lukewarm water. Do not immerse in water or spray directly with liquids.

•The welding shield is heat resistant and approved against standard requirements for flammability but can catch fire or melt in contact with open flames or very hot surfaces. Keep the shield clean to minimize this risk.

•Materials that come into contact with skin may cause allergic reactions to susceptible persons.
