4. With the strap adjuster in the proper position, adjust the chinstrap
tension at the buckle. Adjust the tension so the chinstrap is tight and
comfortable by pulling the chinstrap end through the buckle to either
tighten or loosen as needed. Use the "O-Ring" to secure the excess
strap. Always wear the helmet with the chinstrap buckle fastened and
the chinstrap pulled tight and positioned back against the throat.
With the strap buckled and the helmet positioned, you should feel
the chinstrap pull firmly against your chin as you open your mouth.
When properly adjusted the helmet will wrap around your head and
cradle it with firm, but comfortable pressure.
