BEFORE FIRST USE
1) The auto-darkening welding helmet needs to be charged prior to use and after extended
storage. Leave the solar panel on the helmet facing the sun or bulb light for at least one
hour before first use.
2) Remove the protective shipping film from both sides of the front lens (if not already done).
3) The helmet comes assembled, but before it can be used, the headgear must be adjusted
for proper fit.
• 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 headband. (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 "W"
in Fig. 1.)
