the guide and snapping the pins into the holes to lock securely in place.
TILT: Tilt adjustment is located on the right side of the helmet. Loosen the
right headgear tension knob and push the top end of the adjustment lever
outward until the lever's Stop Tab clears the notches. Then rotate the lever

engage again when released locking the helmet into position.

and lens. To adjust, slide and hold the spring loaded caps upward while mov-
ing the headgear into one of four slotted locations. Once the desired distance
has been achieved let go of the cap and it will return to its resting position
