substances (such as: acids, bases, flux for
welding, oils, detergents). Avoid exposure to
high temperatures, for instance by leaving the
helmet inside a vehicle exposed to sunlight.
Avoid contact with heat or sparks. Do not sit on
the helmet and do not compress the helmet in
a sack. Avoid contact with sharp objects. Avoid
letting the helmet fall.
Temperature of use
The product (dry state) may be used
permanently in the temperature range of -40°C
to +50°C.
Duration and replacement
The duration of the product depends on the
typology and frequency of use and well as on
external factors. Although not used, the helmet
is subject to ageing due to the intensity of UV
rays and weather conditions.
Normal use
Duration in case of normal and proper use,
without evident wear marks and under optimal
storage conditions: 10 years.
Maximum duration of the product under
optimal storage conditions and if not
used: 15 years.
Very frequent use
or under extreme conditions
If the product is used under extreme conditions,
very high or very low temperatures, sea water,
or if exposed to frequent blows and shocks
due to the fall of stones/ice and if it presents
many scratches, its safety features could be
reduced even after a brief period of use so that
the product should be replaced. This helmet is
designed to absorb the energy after an impact.
The absorption of the blow occurs through the
partial breaking or damaging of the shell or the
internal part of the helmet. After a strong impact
(blow, fall of stones or ice) the helmet must be
replaced even if it does not present visible
damages. The same applies in the case of deep
scratches or if the product gets into contact
with chemicals.
Storage and transportation

not exposed to sunlight, chemicals and at a
temperature between 5 and 35 °C. Store the

fatigue originating from crushing, pressure
or traction. During transportation protect the
product from direct sunlight, chemicals, dirt
and mechanical damages. Use a protective
bag or special containers for safe-keeping and
transportation.
