Maintenance And Cleaning - Nolan N21 VISOR Seguridad E Instrucciones

- 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 flapping 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 dam-
aged 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 visi-
ble. 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.
