CASCO PF 112 EXTREME Mode D'emploi page 7

ADJUSTING THE CHIN STRAP
Fasten the strap with the buckle (Fig. 2/11) and regulate the length using the free end of the strap. The PF 112
EXTREME fulfils the requirements of the standard DIN EN 443:2008 in respect of the retention system provided
that the chin strap supplied by the manufacturer is worn and adjusted in accordance with the regulations.
Attention! The protective effect is only achieved when the helmet is ideally positioned, the head band
adapted to the head girth and the chin strap fastened. Only wear the helmet when it is fully assembled.

SERVICE LIFE
The helmets have a maximum service life with no binding expiry date. The service life of these helmets is
influenced by the environment and environmental conditions in which the helmet is used and stored, as
well as the materials used in its construction. This CASCO PF 112 firefighting helmet series is equipped
with an extremely temperature resistant coated shell of highly compressed fiberglass which offers out-
standing durability and is not affected by sunlight (UV rays).
The service life of these helmets is mainly limited by mechanical, thermal and chemical factors. The highly
compressed fibreglass is generally held to be extremely durable against such pressures. The helmets'
load capacity when faced with weather-related, chemical and thermal factors, shows a considerably
better performance than thermoplastic materials.
Warning: The CASCO PF 112 helmet series does not have a binding discard or expiry date, the maximum
service life is dependent on the above-mentioned factors.
In order to achieve a long service life, the instructions for use must be applied. This especially covers
cleaning and maintenance, care and repair measures and advice on how to carry out regular damage
checks. Please note: Every helmet equipped with interior construction and accessories must be checked
for possible damage before and after every use and these checks be documented. If these prerequisites
have been fulfilled and the helmet shows no indication of mechanical, thermal or chemical damage
and if all instructions for use have been followed, CASCO PF 112 series firefighting helmets can easily
be worn for longer than 15 years. Since the shock-absorption parts of the interior construction are not
overtly subject to external influences, we recommend preventative helmet replacement after the above-
mentioned time period.
CHECKING THE SERVICEABILITY
Please carry out an inspection of the helmet shell, internal fittings and chin strap at regular and also
deployment-dependent intervals. A damaged helmet may no longer be used! It must be rendered un-
usable and replaced. The helmet absorbs the energy of an impact accompanied by partial destruction
or damage. Any helmet which has been subjected to a heavy impact must be replaced as the resultant
damage is not always visible.

STORAGE
Protective helmets are to be stored away from sunlight in a cool, dry spot. Avoid direct exposure to sun-
light to prevent possible damage through UV rays to the luminescent paintwork, for example.
STORAGE; USE AND MAINTENANCE
Please carry out an inspection of the visor screen and linkages at regular and also deployment-dependent
intervals. A damaged /scratched visor may no longer be used. It must be rendered unusable and replaced.
INFORMATION IMPORTANT TO YOUR SAFETY
The protection provided by the helmet depends on the circumstances of the accident whereby the wearing
of a helmet cannot always prevent a fatal accident or extended invalidity. Always wear the helmet in the
correct position and bring to mind that no helmet can guard the neck area or the unprotected parts of the
head. This helmet is approved solely for use by the fire brigade, in rescue and disaster control. It is not
approved for sport and motorcycling.
Warning: Please note that helmet wearing safety can only then be ensured when it has been fully assem-
bled and correctly fitted, and that removable parts cannot be worn separately.
HELMET IDENTIFICATION
All safety helmets are provided with the date of manufacture, the type, the size, the standards specifi-
cation and mark for optional safety requirements. The identification is located at the back on the inside
of the helmet shell.
Size and weight of the helmet including visor: PF 112 EXTREME: 53–64 cm / ~ 1050 grams
