  • Mount belt, check position of cape and close belt with ratchet.

 

8.5  Replacement of Collar

The inner collar plays an important role in controlling air escape from the helmet and preventing ingress of dust. To replace or wash the collar it has to be detached with the zip from the cape (see point 9 for service maintenance and cleaning).
The cape must be replaced when the collar is stretched to the point where it no longer fits snugly around the neck.

8.6  Replacement of Lens Frame

The lens frame must be replaced if a seal is not maintained any more or if the rubber latch doesn’t stay closed. When changing the lens frame the acoustic pads in the inner part of the helmet should be changed also.

The chinstrap must be replaced at the first sign of wear.
To get the chinstrap off the holder push it up into the helmet till it snaps out, then take it off the holders. When replacing the new chinstrap, check that the bevelled side faces the centre of the helmet.
