GENERAL RULES
EN
The integrity of the outside fibers shell and of the inside polystyrene shell is essential to assure maximum performan-
ces in terms of safety.
JUST 1 Helmets
was designed to absorb crashes through a partial destruction of the shell or some of its parts that
could be damaged after a crash even if it is not readily visibly. If the helmet suffers further stress it might not be able
to offer the maximum level of protection.
Do not use a helmet that suffered severe blows even though the damage is not readily visible; if the helmet is
damaged it must be replaced.
It is extremely dangerous to modify the helmet by sticking or gluing anything on it.
Do not cut or punch the helmet’s shell, do not insert screws or paint it.
Do not change the internal lining of the helmet, particularly never cut or change the inside polystyrene padding:
chan-
ges to the shape of the internal polystyrene shell can affect the safety features of the helmet.
Only use original
JUST 1 Helmets
accessories and spare parts or those specifically indicated by JUST ONE s.r.l. for the
specific model: this is the only way to assure reliability, safety and compatibility with the helmet used.
The use of non original components and/or accessories makes the warranty void (see warranty conditions on page
30) and can affect the safety requirements.
