CAUTION: Be sure to set the helmet to the proper shade setting before welding again.

Adjust the Headband width by turning the Ratcheting Headband Knob to make sure the Front Cover Lens is aligned with your eyes.

Adjust the Headband height by tightening or loosening the top strap until the Helmet fits snug on your head.

Once the Headband is properly adjusted, lower the Helmet over your face until the proper angle is found. Then turn the Tension Adjustment Knobs on either side of the helmet, locking the helmet’s angle in place. See Figure 3.
