HELMET CARE AND MAINTENANCE
Replacing Front Cover 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 Cover 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. Hinge down the wire loop and ensure the front
edge of the loop (D) is properly retained under the retaining lugs (E) as
shown in (figure 3).
Position the shade potentiometer to the inside of the helmet with the shaft
protruding through the hole. Secure potentiometer to shell. On the outside of
the helmet, push the shade control knob onto the shaft.
Installing an Aftermarket Magnifying Lens: Unclip the wire loop (D) from
retaining lugs (E) and move hinge up. Place magnifing lens over ADF viewing
area and retain with wire loop.
Cleaning: Clean helmet by wiping with a soft cloth. Clean cartridge surfaces
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.

Test your shade cartridge prior to welding by directing the front of the car-
tridge toward a bright source of light, then using your fingers rapidly cover
and uncover the sensors. The cartridge should darken momentarily as the
sensor is exposed. A torch striker can also be used.
