Maintenance
MINOR AND ROUTINE MAINTENANCE
1. Use only at temperatures: -10 °C ~ +55 °C
(14 °F ~ 131 °F).
2. Storing temperature: -20 °C ~ +70 °C (- 4 °F
~ 158 °F). The helmet should be stored in
a dry, cool and dark area with the battery
removed when not in use.
3. Protect filter from contacting with liquid
and dirt.
4. Clean the filter surface regularly; do not use
strong cleaning solutions. Always keep the
sensors and solar cells clean using a clean,
lint-free tissue.
5. Replace the front lens cover if it becomes
cracked, scratched or pitted.
MAJOR MAINTENANCE, SERVICE, AND
PART REPLACEMENT
1. REPLACING FRONT COVER LENS.
Replace the front cover lens if it is
damaged (cracked or pitted). Place your
finger or thumb into the recess at the
bottom edge of the window and flex the
window upwards until it releases from one
edge (see Fig.6).
2. REPLACING THE INSIDE COVER LENS.

Replace the inner cover lens if it is
damaged (cracked or pitted). Place your
finger or thumb into the recess at the upper
edge of the window and flex the window
upwards until it releases from one edge.
3. CHANGING THE SHADE CARTRIDGE.
Loosen the holding spring (see Fig.6a-D),
move out the shade cartridge and put new
shade cartridge into the filter frame; affix
the cartridge by using the spring (see
Fig.6a-E).
4. FITTING NEW CARTRIDGE.
Take the new shade cartridge and pass
the potentiometer cable under the wire
loop before dropping the cartridge into its
retaining frame inside the helmet. Hinge
down the wire loop clip and ensure that
the front edge of the loop is properly
retained under the retaining lugs as shown
in Fig. 6b.
5. Fasten the potentiometer to the inside of
the helmet with the shaft protruding
through the hole. Push the shade control
knob onto the shaft.
