2. Headgear Suspension: Look for cracks, rips, fading, or other damage. Ensure headgear suspension ratchet operates properly. Inspect the
overhead plastic adjustment straps for cracks or damage. Look at sweatband to make sure it is in good working order. Ensure suspension is
properly attached and pivots easily. See "Welding Helmet Donning & Fitting" section for instruction regarding removal and replacement of the
head suspension. To replace the sweatband:
a. With the welding helmet in the "up" position, remove the old sweatband from the welding helmet. The headgear suspension may first be
removed to make replacement easier.
b. Place the new sweatband corners around its retainer (Fig. 18a).
c. Pull the sweatband holding loops over the hooks on the retainer for a secure fit (Fig. 18b and 18c).

3. 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. Make sure it is installed correctly and replace as
necessary. To replace the inner grinding visor and frame:
a. Lift on the tabs on either side of the frame to remove it from the inner grinding welding helmet (Fig. 19a).
b. While looking at the front of the welding helmet, push out on the grinding visor tabs located on the right side to remove the clear visor
(Fig. 19b).
c. To reinstall a new grinding visor, hook the four tabs (the 2 left first, and then the 2 right) into their slots on the welding helmet
(Fig. 19c and 19d).
