system and chin strap buckle work properly.
Changes to original components
The possible change or removal of original
components of the product can limit its safety
features. It is highly recommended that no
modifications or adjustments are made to the
equipment to add further components unless
explicitly advised so by the manufacturer in
writing. Apply colours, solvents, glue or sticky
labels only if they comply with the information
provided by the manufacturer.
Warning! The products must
not be exposed to dangerous
conditions and improper treatments.
Avoid contact with corrosive or aggressive
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.
Periodical checks
Apart from checks before use, the helmet must
undergo a thorough check when required and
needed, by the manufacturer, by an expert
