4.3) Micrometric adjustment buc-
1 2
kle retention system
With the micrometric adjustment re-
tention system, the strap must be
adjusted before being fastened.
Following the indications of the figu-
re 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 serra-
ted 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
enable further, more precise "cali-
bration" of comfort and fit thanks to
the possibility to use the preferred
number 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 "Choo-
sing 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 fi-
gure below.
N.B. BUTTONS/VELCRO POSI-
TIONED ON THE RETENTION
SYSTEM ARE NOT FASTE-
NINGS BUT ARE ONLY TO
PREVENT FLAPPING: THEY
MUST NOT BE USED AS AN
ALTERNATIVE TO FASTENING
THE STRAP.
