C. THE HELMET
Installing the face shield
1. Using both hands, guide the face shields
locking studs into the respective recesses in
the face shield mechanism.
2. The face shield will then audibly lock into place
when you press it gently towards the helmet
with a simultaneous closing movement.
3. Check the function of the visor mechanism
by closing the visor once and opening it as
far as possible.
Safety note
Check before each journey that the face shield and sun visor mechanism are
functioning correctly and that the face shield and sun visor will provide good
visibility. Any dirt should be removed before setting off. Check the face shield
and sun visor for physical damage and cracks. Severely scratched or scuffed
face shields will seriously impair visibility and should be replaced before setting
off on a journey.
