Subsequently, the two screws (hexagonal socket) on the
lateral chinstrap fixing are to be loosened (B).
Following the opening of both short neck straps (C), the
chinstrap can be slipped out and then washed in a wa-
shing machine at low temperature (use a mild detergent
only).
During reassembly, it is recommended that the head
strap be inserted first and the over head strap Velcro
fixing securely fastened. The two neck straps should
then be fixed and the lateral screws mounted.
After reassembly of the chin strap make sure that all
straps and screws are securely fixed to the helmet.
Inspection
Inspect each element of the helmet assembly after EACH use
carefully for function, cleanliness, tears, cracks, holes and any
physical, impact, thermal and use damage. Disassemble and ca-
refully inspect helmets that have been exposed to excessive
heat ore have taken an impact. Replace ANY part showing wear
or damage.
Helmets absorb the energy of a blow by partial destruction of,
or damage to, the helmet. Even though such damage may not be
readily apparent, any helmet subjected to a severe impact
should be replaced immediately.
If there is a damage, remove the helmet from service immedia-
tely and repair or replace the damaged part before using the
helmet again.

Retirement criteria
Your fire department or employer must determine whether or
not your protective helmet assembly is ready for retirement and
replacement.
The service life of this protective helmet will vary depending
upon how much it has been used and how well it has been clea-
ned and maintained.
If you are unsure whether your protective helmet should be reti-
red, do NOT use it.
Unless the responsible authority determines that your protecti-
ve helmet is ready for retirement earlier, the over all service life
of this protective helmet shall not
exceed a total period of 10 years.
