push the neck dam/ring up into the neck ring on the
base of the helmet. The neck dam ring fits very snugly

Push the locking collar/neck pad assembly up into
position until it locks with the sealed pull pins.
If you have not positioned the sealed pull pins into
the locking position, do it now with the locking
collar/neck pad assembly in place.
