D. THE HELMET
If the anti-fog lens is not air-tight and the face shield mists up, either the
visor is not correctly in place or the pressure on the seal is inadequate.
You can regulate the pressure on the seal by adjusting the eccentric
locking-pins. To remove the anti-fog shield, use a rubber spanner to turn the
retaining pins 180°, and then reinsert. Fit the anti-fog lens and check the seal.
Removal
1. Before starting to remove the anti-
fog lens, first lay the face shield on a
soft, clean cloth so that its top edge is
facing you.
2. To reduce the pretensioning of the anti-
fog lens slightly if necessary, use the
balls of your thumbs to carefully bend
the face shield sufficiently apart while
applying pressure with your thumbs to
release the anti-fog lens and move it
approx. 2–3 mm forward.
3. Now grip the back of the anti-fog lens
with your index and middle fingers and
lift it off the face shield. In this position
you can easily remove the anti-fog lens
from the locking pin with your thumb.
4. You can now remove the anti-fog lens
from the face shield.
Note:
To avoid scratching the face schield, never remove or fit the anti-fog
lens unless the visor unit is clean and dry.
When fitting the anti-fog lens, check that neither dust nor moisture are
able to get between the two surfaces.
When removing or fitting the anti-fog lens, it is always best to lay the
face schield unit on a clean, dry cloth.
