To install the size reducing pad:
1. Remove the standard S-953 comfort pad by gently pulling the pad off the attachment points.
2. Secure the S-954 Size Reducing Comfort Pad to the suspension according to Fig. 17a-d. The two

WARNING
The ‘in use’ life of these products will vary with frequency and conditions of use. Before and after each
use, inspect for signs of damage or wear.
Carefully:
• Examine the condition of the fabric, head suspension, visor, outer shroud, and as applicable, inner
shroud, collar, or elasticized faceseal. Check that there are no cracks, rips, dents, holes, tears, or
other damage.
• Look closely at the stitching. Ensure stitching is intact and there is no unraveling or gaps in the
seams. There should be no tears or holes that could permit contaminated air to enter the hood or
headcover.
• If using the S-800 series hood, closely inspect the sealed seams for rips, holes, tears, or other
damage. Ensure side ties are present and undamaged.
• Look for scratches or other visual distortions that could make it diffi cult to see through the visor.
• Examine the head suspension for cracks or other damage.
• Examine the entire breathing tube. Look for tears, holes or cracks. Bend the tube to verify that it is
fl exible. Ensure the gasket located in the QRS (i.e. the end connection to headgear) is present and
not damaged. If using a BT-Series breathing tube, inspect the gasket located on the bayonet end of
the breathing tube (i.e. the end that connects to the airsource) for signs of damage. The breathing
tube should fi t fi rmly into the airsource connection.
If you discover any signs of wear and/or damage, discard the component and replace it with
a new one. Failure to do so may affect respirator performance and reduce the degree of
protection provided.
