Maintenance And Cleaning - Nolan N90 Sicherheit Und Gebrauchsanleitung

- The helmet should not rotate nor move on the head and should not slide off. Should
the contrary happen, adjust strap length or change helmet size. Repeat test.
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 under
the chin, as close as possible to the throat, but without being uncomfortable.
- The correct strap tension should allow normal breathing and swallowing, but without
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 flap-
ping once the strap has been fastened properly.
• VISOR:
- If the visor is damaged or deeply scratched causing reduced visibility, this means that
the protective 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 received
violent impacts, are to be replaced.
- Attention: Helmet and visor may be seriously damaged by some common substances
without the damage being however visible. Use only lukewarm water and mild soap to
clean helmet and visor, and then let them dry at room temperature away from sunrays
and/or heat sources.
- Attention: Never use petrol, thinner, benzene, solvents nor other chemicals which may:
• Irreparably damage the helmet
• Modify optical properties, reduce mechanical ones and weaken the visor protective
treatment.
