• 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. 9). 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
‘Y’
nearest hole. (See adjustment “W” in fig. 9).

• Front and back bands will automatically self-adjust according to headform, and soft pads suit
forehead and back of head perfectly, which will bring more comfort (see fig. 10a). 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: Press down and hold the “LOCK” latch on both sides (see fig. 10b) and it can be
slide back and forth.
Step 2: Loosen the “LOCK” latch and keep it snap into slots. Please make sure the distance
between the lens to both eyes are equal, to avoid uneven darkness.
• ADJUSTING VIEW ANGLE POSITION
Tilt adjustment is located on right side of helmet. Loosen the right headgear tension knob and
adjust the lever forward or back to the proper position. Re-tighten the right headgear tension
knob (see fig. 10c).
