out of the hole.

2. Adjust the strap length until the sweat band is positioned just above your eye brows.

3. Snap the bead into the closest hole in the strap.

Figure 1. Model H7787.

Shade Filter

The shade chart below shows recommended shade filters needed for various welding process es. We recommend that you start ANY welding

process at #13 and reduce the shade as needed for safety.

Angle

1. Looking at the back of the helmet, locate the

friction knob on the right hand side and loos en it 4 or 5 complete turns. It is not necessary to remove it completely.

2. On the side of the helmet and just below the friction knob are 3 holes. One of these holes will be occupied by a plastic pin. Push the pin in toward the inside of the helmet and posi tion it over the desired hole.

3. Insert the pin and tighten the friction knob.

Choosing the hole furthest from the front of the helmet will allow the helmet to tilt further forward. Choosing the hole closest to the front will allow the helmet to tilt less.

Flip-down Friction

1. Tighten or loosen the friction knobs located

on either side of the helmet to increase or decrease the amount of effort needed to raise and lower the helmet.
