1) To reassemble the L-163 Foam Liner:

a. With the foam liner positioned such that the model number is
oriented to the front of the headgear shell, insert the foam liner into
the headgear shell. If the liner is hard to install, you are probably
inserting it backwards.
b. Reinstall the complete suspension assembly to secure the liner.
NOTE: The cut-out pockets in the foam liner must align for the
head suspension to fit into the headgear.

2) To replace the L-115 Sweat Pad:

a. Wrap the sweat pad around the headband, in the area that comes
into contact with your forehead.
b. Secure the sweat pad by closing the three snaps.

3) To replace the L-116 Head Pad:

a. Orient the head pad such that the padded surface is facing you
(so that it will be in contact with your head when installed in the
headgear).
b. Slip the head pad tabs into the four slots in the hanger suspension.

4) To replace the L-117 Hanger Suspension:

a. Place the ladder tabs in the slots on the headband, then turn the
four ladder tabs a quarter-turn.

5) To replace the L-113 Head Suspension:

a. Place the 4 mounting clips back into the slots in the headgear.
