Operation
Application
Check the front cover to make sure it is clean and that
the sensors on the front of the filter cartridge are not
dirty. Also check the front/rear cover lens and the front
lens holder snap connection to make sure they are faste-
ned.
Check the helmet and viewing window for signs of wear
or damage before each use. Scratched, cracked or scar-
red parts should be replaced immediately before re-use
to avoid serious injury.
Adjust the headband so that the helmet sits as low as
possible on your head and close to your face. Adjust the
angle of the helmet in the lowered position by pressing
the side adjustment knob.
Do not make any modifications to the welding lens or
helmet other than those specified in this manual.
Failure to observe these warnings and / or to follow all
operating instructions may result in serious injury.
