enter the threaded end of the handle through
the holes provided. Thread on the plastic nut

Always maintain the welding mask in good
condition. If the clear glass protection lens
becomes badly pitted, sufficient to interfere
with vision, or cracked, have it replaced
immediately. Replacement clear and dark
lenses are available from your Clarke dealer
- see Parts Lists for details. NEVER use any dark
filter lens other than that provided by CLARKE
International, or one with the same certified ‘Optical class’ (degree of protection).
The shield should always be cleaned with a clean soft cloth after use, ensuring the lenses
are clean. Remove any dust that may have accumulated and store it in a safe place
where it cannot be damaged. NEVER use a shield that is
not
in perfect condition.
The clear glass panel should be replaced when it becomes badly pitted.
