HELMET CARE AND MAINTENANCE
Replacing Front Clear Lens: Replace the front cover lens if it is damaged –
cracked, soiled or pitted. Place your finger or thumb into recess (C) at the
bottom edge of the cover lens and flex the lens upwards until it releases from
the edges marked A and B. (Refer to figure 1). Use only the replacement
front cover lenses specified in this manual.
Replace the Inside Clear Lens: If it is damaged (cracked, soiled or pitted).
Place your fingernail in recess above cartridge view window and flex lens
upwards until it releases from edges of cartridge view window.
Change the Shade Cartridge (See figure 2)
Fitting New Cartridge: Take the new shade cartridge and pass the poten-
tiometer cable under the wire loop before placing the cartridge into its retain-
ing frame inside the helmet. Lower the wire loop and ensure the front edge of
the loop (D) is properly retained under the retaining lugs (E) as shown in (fig-
ure 3).
Position the shade potentiometer inside of the helmet with the shaft protrud-
ing through the hole. From outside of the helmet, position dial panel onto the
potentiometer shaft and secure potentiometer to shell, rotate shaft counter-
clockwise until an audible click is heard and install shade control knob with
pointer positioned at Grind location on dial panel.
Cleaning: Clean the helmet by wiping with a soft cloth. Clean cartridge sur-
faces regularly. Do not use strong cleaning solutions. Clean sensors and
solar cells with soapy water solution and a clean cloth and wipe dry with a
lint-free cloth. Do NOT submerge shade cartridge in water or other solution.
Storage: Store in a clean, dry location.
