Adjusting Headgear

�
There are four headgear adjustments:
headgear top, tightness, angle, and
distance.
1 Headgear Top
Adjusts headgear for proper depth on the
head to ensure correct balance and stability.
2 Headgear Tightness
To adjust tightness, push in adjustment knob
and turn left or right to desired tightness.
3 Angle Adjustment
Notches on the right side of the headband
provide adjustment for the backward or for-
ward tilt of the face shield. To adjust, loosen
the headgear tension knob and push the top
end of the control arm outward until the

arm's stop tab clears the notches. Rotate
the control arm backward or forward to the
desired angle position.
4 Distance Adjustment
Adjusts the distance between the face and
the lens. To adjust, loosen both tension
knobs and slide headgear forward or back-
ward to desired position. Tighten knobs.
�
5 Headgear Cushion
The cushion disperses the weight of the
headgear on the head and helps prevent the
face shield from slipping when the lens is
raised and lowered.
3
Both sides must be equally positioned
for proper operation.
