at its lower edge with the thumb. When replacing, take care it lays evenly on
the lips provided.
CLEANING & STORAGE

headshield should be stored in it’s box or similar place.
Clean all lenses with a soft tissue and suitable lens cleaning fluid. Do not use
solvents. Never use tools or other sharp objects to remove material from the
filter or helmet. This may cause damage which may cause incorrect function
and invalidate the warranty.
