4.3) Micrometric adjustment
1
2
buckle retention system
With the micrometric adjustment re-
tention system, the strap must be
adjusted before being fastened.
Following the indications of the fig-
ure below, adjust the length of the
strap, lengthening or shortening the
portion of tape that passes through
the metal ring (1) until the helmet fits
snugly when the strap is fastened.
To fasten the helmet, slot the serrat-
ed tab into the metal buckle (2) and
3
push it as far as possible (3) until the
strap presses against the jaw. The
micrometric adjustment system en-
able further, more precise "calibra-
tion" of comfort and fit thanks to the
possibility to use the preferred num-
ber of positions on the serrated tab
(It is best to insert the tab as far as
possible into the buckle).
Check that the helmet fits snugly
(see the paragraph entitled "Choos-
ing the right helmet" in the "Safety
Warning" booklet).
To remove the helmet, lift the red
4
5
lever using the ribbon (4) and then
open the buckle (5) as shown in
figure below.
N.B. BUTTONS/VELCRO POSI-
TIONED ON THE RETENTION
SYSTEM ARE NOT FASTEN-
INGS BUT ARE ONLY TO PRE-
VENT FLAPPING: THEY MUST
NOT BE USED AS AN ALTER-
NATIVE TO FASTENING THE
STRAP.
