Before and after each use, inspect entire headgear for signs of damage or wear including dents, rips, cracks,
color changes, chalking, fading, flaking and penetration. Carefully inspect all headgear components including the
following:
• Clear grinding visor and visor frame: Look for scratches or other visual distortions that could make it
difficult to see through the clear grinding visor. Look for signs that the clear grinding visor or the visor frame
has warped or cracked and is installed correctly and replace as necessary. Ensure the inner shield holding
the clear grinding visor stays firmly in the up (open) and down (closed) positions.
• Head suspension: Look for cracks, rips, fading, or other damage. Ensure head suspension ratchet operates
properly. Inspect the web straps for rips, tears, fraying, or fading. Look for worn stitching. Ensure straps are
properly attached.
• Faceseal: Look for tears, holes, gaps in sewn seams, damage to stitching or other damage. Ensure faceseal
is securely and properly attached.
• Headgear shell: Look for visible damage including dents, cracks, color change, chalking or fading. Any 3M™
Speedglas™ Welding Helmet 9100 MP subjected to severe impact should be removed from service and
replaced even if damage is not readily apparent.
• Breathing tubes: Look for tears, holes or cracks. Bend the tube to verify that it is flexible. Ensure the gasket
located in the QRS is present and not damaged. Inspect the gasket located on the bayonet end of the
breathing tube (i.e., end that connects to the airsource) for signs of damage. The breathing tube should fit
firmly into the airsource connection.
• PAPR blower assembly: Inspect according to the User Instructions for your specific airsource.
• 9100 ADF: Carefully inspect the complete 3M™ Speedglas™ ADF 9100 before each use. Cracked, pitted
or scratched filter glass or protection plates reduce vision and can seriously impair protection. All damaged
components should be replaced immediately.
Inspect date codes on helmet shells, and other plastic components and ensure parts have not exceeded their
maximum life. See Expected Life section of these User Instructions for additional information.
If you discover any signs of wear and/or damage, remove headgear from use and service or replace as
appropriate. Failure to do so may affect respirator performance and reduce the degree of protection
provided.
