Shark RS-JET CARBON Manual página 23

WARNING! No helmet can
fully protect the user from all
possible collisions at high or low speed.
However, for effective protection, the
helmet must be the right size and the
chin strap must be properly tightened
as indicated in the manual. It is
dangerous to use a helmet that does
not fit properly or to not tighten the
chin strap closure system correctly,
because the helmet could come off
your head in the event of an accident,
causing serious or fatal injuries.
CHOOSING YOUR SIZE
Each helmet from XS to XXL is designed
for a given head size. To measure your
head circumference, use a tape measure
by wrapping it horizontally 2.5 cm above
your eyebrows. If the measurement
is between two sizes, try the smallest
helmet first. However, due to the
different skull shapes, size references
are only to help you select the correct
size for your head.

For effective protection, it is necessary
to ensure that the helmet fits your head
well. When you choose a new helmet,
ensure that your head is firmly seated
in the helmet, with the top of the field of
vision positioned above the eyebrows.
Also ensure that the chin strap is
properly tightened as indicated on the
following page.
1. Your head must be fully encased by the
helmet and your cheeks must provide
good support. If this is not the case, the
chosen helmet is too big, try so a smaller
size.
See Figure A.
2. With the chin strap properly tightened,
make sure the helmet does not move too
much from left to right and from top to
bottom. You should feel your skin of your
head and face pulling when you move the
helmet. If this is not the case, the chosen
helmet is too big, so try a smaller size.
See Figure B.
