the harness, squeeze the fastener with your thumb and forefinger and pull out
the strap with the other hand.
2. Adjust the ear muffs to your ears and remove long hair from the cushion
surfaces or tie up long hair.

by any hard or sharp flying particles.

helmet and do not apply paint or similar on the helmet. Do not apply solvents
and labels on the surface. Do not stick other labels over the safety labels!
