Adjustment of the Headgear for Maximum Comfort
There are four adjustments on Hobart headgear that can be adjusted for
maximum comfort:
1. Headgear Top – Adjusts headgear for proper depth on the head to en-
sure correct balance and stability.
2. Headgear tightness – To adjust, turn knob located on the back of the
headgear left or right to desired tightness.
3. Stop angle adjustment – Five pins on the right side of the headband top
provide adjustment for the forward tilt of the helmet. To adjust, loosen the
right outside tension adjustment knob and lift on the control arm tab to
move it to the desired position. Retighten tension adjustment knob.
4. Distance adjustment – Adjusts the distance between the face and the
lens. To adjust, loosen both outside tension knobs and slide forward or
back to desired position and retighten. (Both sides must be equally posi-
tioned for proper vision.)

the retaining clips located on the outside of the auto-darkening lens
assembly.
