4.1.1 Adjusting the helmet size:
Wearing the helmet
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.

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.

4.1.2 Adjusting the height:

The height is adjustable in ten positions by means
of 2 ratchet adjusters located on the headband on
the left and right rear side of the helmet liner. The
helmet should be adjusted so that the eyes are
aligned with the vertical center of the visor.
CAUTION: When adjusting the ratchet adjusters it is important to listen for the audible
snapping of the adjuster into position on both sides after the adjustment in order to
ensure a proper safety function of the helmet liner.
