SUOMY Rumble Instructions D'utilisation page 23

Only the correct assembly of the cheek pad and the correct
positioning of the strap will assure the proper operation of the
retention system.
If this doesn't happen and the removable cheek pads don't work
correctly, do not use the helmet and contact Suomy authorized
personnel only.
Internal central padding : fitting and removal
Removal – see fig. 5A
The internal padding is fixed to the helmet through 2 back stud
buttons and in the front part through a click-in tongue. There are
also two side tongues that fix the internal padding to the
polystyrene.
Remove the removable cheek pads (refer to paragraph CHEEK
PADS). Release the back stud buttons and release in the front
part of the polystyrene, the click-in tongue from its seats. Slide
out the two side tongues that fix the internal padding to the
polystyrene. Remove the internal padding.
Caution: to avoid damaging the internal lining, before removing
the padding, make sure the tow back stud buttons were
released.
