• Never ride with the chinstrap unfastened or incorrectly adjusted. The chinstrap must be
correctly
positioned and must not come loose when pulled. The fastener is not correctly closed if the
chinstrap becomes loose when pulled.
• The full protective function of a helmet can no longer be guaranteed after an accident or
impact. Like the crumple zone of a car, the impact energy of a collision is absorbed by
complete or partial destruction of the structure of the outer and/or inner shell of the helmet.
Because of the way helmets are designed, this damage is rarely visible from the outside.
The safety helmet is designed to absorb only one impact. It is therefore essential to replace
the helmet after a fall, accident or other violent impact. For safety reasons, the old helmet
should be rendered unusable.
• The helmet safety mechanism described above can also cause small cracks in the shell
when the helmet is dropped from a small height (less than 1 meter).
• Any helmet that has been subjected to a violent impact should be replaced.
• No helmet provides absolute protection from all conceivable impacts. This helmet has been
specially developed for motorcycle riding and is unsuitable for other purposes.
• Examine the helmet for damage at regular intervals. Small scratches will not impair the
protective function of your helmet.
