E. BEFORE EVERY JOURNEY
For your safety, check the following points before every journey:
1. CHECKING THE HELMET
Check the helmet regularly for damage. Small superficial scratches will not
impair the protective function of your helmet. In the case of more serious
damage (cracks, dents, flaking and cracking paint, etc.), the helmet should no
longer be used.
2. CHECKING THE CHINSTRAP
(WITH HELMET ON AND FASTENED)
1. Check that the chinstrap passes under your chin.
2. Slip your index finger under the chinstrap and pull.
If the chinstrap is loose under the chin, it is too long and needs to be
tightened.
If the chinstrap loosens when you pull it, it is not properly fastened. Undo
the chinstrap completely and try fastening it again. Repeat the test.
3. If you are unable to fasten the chinstrap so that it fits snugly against the
chin, check that your helmet is still the right size for you.
Note:
Repeat the test after each adjustment.
Caution:
Never ride with the chinstrap unfastened or incorrectly adjusted. The
chinstrap should fit correctly and should not become loose when pulled.
The fastener is not correctly closed if the chinstrap becomes loose when
pulled.
