Rosenbauer – HEROS-matrix
3.5 Neck protector
The helmet is equipped with a neck protector. All the materials are flame
retardant and highly heat resistant. The neck protectors are attached with
a clamping strip to the helmet liner or to the helmet shell and can be easily
removed for cleaning. The neck protector amply covers the neck and ears while
still allowing for problem-free communication. Neck protectors are wear parts; a
sufficient number should be kept in stock.
WARNING: The neck protection is a protective guard, which is made of a soft flexible
material. These materials have a limited ruggedness and can only provide limited
protection. In operations in which a flashover or a similar event is to be expected, we
strongly recommend that all-round neck protection and a flame protection hood be
used.
4. USER'S INSTRUCTIONS
4.1 Adjustment before use
4.1.1 Adjusting the helmet size
The unique method of adjusting the headband to the individual head size from the
outside provides a basic adjustment means. The adjustment knob on the outside
of the helmet can be used to infinitely adjust the size from 51 to 65. If the hat size
is smaller, the basic width of the headband can also be adjusted (4.1.3). Open the
helmet band, put on the helmet, tighten the helmet band until there is a snug fit
without any uncomfortable pressure.
Wearing the helmet on
CAUTION: Do not forcibly continue to turn the knob when the stop has been reached.
Of course the helmet can be adjusted as needed to adapt to the given conditions
during an operation - under observance of all safety regulations.
