8.14 Head Cushion and Chin Cushion

8.14.1 Head Cushion Foam

The head cushion (40) foam must be replaced when

the foam begins to crumble. Order Replacement

Foam Kit (Part #510-672). A loose head cushion

will create a sloppy fit to the helmet and cause dis-

comfort to the diver.

8.14.2 Chin Cushion Foam

Like the head cushion, the foam in the chin cushion

must be replaced when the foam begins to crumble.

The foam for the chin cushion is included when the

kit for the head cushion is ordered.

The head cushion foam is easily replaceable.

The chin cushion.

Note: If the head moves, the helmet should follow.

A loose fitting head cushion will cause

poor oral nasal mask fit resulting in CO

buildup in the helmet. This condition

could lead to a build up in CO

(Hyper-

capnia), possibly resulting in uncon-

sciousness, serious injury or death.
