CHANGING THE SHADE CARTRIDGE.
All components clip into the front of the helmet as shown
in fig.5 above.
5.1.1 To access the cartridge firstly remove the front cover ‘A’
by releasing the four clips accessible on the inside of the
helmet above and below the cartridge.
5.1.2
Release the top clips first (see ‘A’ in fig.4) by pressing
them downwards and forwards. Then release the bottom
clips (see ‘B’ in fig.4) by pressing them upwards and
forwards.
Lift off the front cover.
5.1.3 Pull the grey knob off the potentiometer shaft on the side
of the helmet. Unscrew the nut at the base of the shaft
and remove it. Push the shaft through into the inside of
the helmet so that the potentiometer is hanging free on
its lead.
5.1.4 Referring to fig.5, push downwards on the two clips ‘H’
whilst pushing the bottom edge of the cartridge outwards
from inside the helmet. When it is free from the lower
clips pull the cartridge downwards and forwards to free it
from the upper retainers. See ‘G’ in fig.5.

under the upper retainers ‘G’ ensuring that the
potentiometer has passed into the inside of the helmet.

turn the shaft anticlockwise until it clicks into the ‘off’
position. Push the knob back onto the shaft so that the
pointer points to the ‘Grind’ position.
5.2.2 Place the front cover ‘A’ onto the front of the helmet so
that the cover clips pass into the matching holes in the
helmet. Press firmly on the top of the cover to engage
the top clips then press firmly at the base of the cover
to engage the lower clips.

the retaining points until it is in position. Ensure that it
laps over the inside of the window opening on either
side.
