1. Chinstrap:
Tools: Philips screwdriver.
Dismantling duration: 15 seconds.
Mounting duration: 30 seconds.
The chinstrap is secured to the helmet by means of two screws on the left chinstrap
bracket.
To remove the chinstrap, unscrew the screws on the left side, then take out the
chinstrap levers by holding them by the ends.
To reinstall, engage each lever, making sure the chin cup is the right way round (the
return part of the strap should be uppermost) and so are the levers. Lock by pressing in
the middle of the lever. Tighten the 2 screws. You do not have to remove the chinstrap in
order to take off the chin cup.
Important: when reinstalling, the screws should be tightened 1/8 of a turn from when
the tightening stress increases (screwing into plastic).
