HELMET PREPARATION
ADJUSTING RETENTION (CHIN STRAP)
BUCKLE THE CHIN STRAP.
With both hands, adjust the two rear slide adjustments simultaneously until the straps are snug.
With both hands, adjust the two front slide adjustments simultaneously until the straps are snug.
NOTE:
This technique works best if you only hold the slide adjustments and don’t touch the straps.
CHECK THE HELMET STABILITY.
Attempt to rock the helmet back and forth on the head. If the helmet rocks back and forth, it is not stable.
Adjust the straps further until the helmet is stable.
NOTE:
Release the buckle to remove the helmet.
Ensure that all helmet adjustment mechanisms are properly adjusted for a snug, secure fit at
all times when the helmet is worn. Failure to do so can result in an unstable helmet that will
not protect the wearer.
