WARNING!Before using the helmet for welding, ensure that you have
• The helmet comes ready assembled, but before it can be used it must be adjusted to fit the user properly and set up for
delay time, sensitivity and shade level.
ADJUSTING THE FIT OF THE HELMET
The overall circumference of the headband can be made larger or smaller by rotating the knob on the back of the head-
band (See adjustment "Y" in fig.1). This can be done while wearing the helmet and allows just the right tension to be set
to keep the helmet firmly on the head without it being too tight.
• If the headband is riding too high or too low on your head, adjust the strap which passes over the top of your head.
To do this release the end of the band by pushing the locking pin out of the hole in the band. Slide the two portions of
the band to a greater or lesser width as required and push the locking pin through the nearest hole (See adjustment
"\N" in fig.1).
• Test the fit of the headband by lifting up and closing down the helmet a few times while wearing it. If the headband
moves while tilting, re-adjust it until it is stable.
• ADJUSTING THE DISTANCE BETWEEN THE HELMET AND THE FACE
Step 1: Undo the block nut (See "T" in fig.1) to adjust the distance between the helmet and your face in the down
position.
Step 2: Loosen the block nut on either side of the helmet and slide it nearer or further from your face (See adjustment
"Z" in fig.1). It is important that your eyes are each the same distance from the lens. Otherwise the darkening effect may
appear uneven.
Step 3: Re-tighten the block nut when adjustment is complete.
• ADJUSTING VIEW ANGLE POSITION
TILT: Tilt adjustment is located on right side of helmet. Loosen the right side 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 forward or back
to the desired tilt position. The Stop will automatically engage again when released locking the helmet into position
(See fig.2)..
