Retention System:
- The retention system (strap) is factory-adjusted at a standard length. Before use, check that it
is correctly pre-adjusted.
- Make sure the strap is properly fastened and tightened so as to keep the helmet firmly in place.
Anyway, before riding, make sure that the strap is well fastened underthe chin, as close as pos-
sible to the throat, but without being uncomfortable.
- The correct strap tension should allow normal breathing and swallowing, but with out leaving
the space of a finger between strap and throat.
- Attention: the button which may be present on the strap only prevents its end from flapping
once the strap has been fastened properly.
• VISOR:
- If the visor is damaged or deeply scratched causing reduced visibility, this means that the pro-
tective treatment is probably damaged so the visor is to be replaced.
- Do not paint nor apply stickers.
- The visor can be used only for the intended helmet model.

• MAINTENANCE AND CLEANING

- Damage resulting from accidental fall may not be visible; helmets, which receivedviolent
impacts, are to be replaced.

the damage being however visible. Use only lukewarm water and mild soap toclean helmet and
visor, and then let them dry at room temperature away from sunrays and/or heat sources.
