SPECIFIC SAFETY PRECAUTIONS
WARNING! DO NOT let comfort or familiarity with product (gained
from repeated use) replace strict adherence to the tool safety rules.
If you use this tool unsafely or incorrectly, you can suffer serious
personal injury.
WARNING! The welding mask does not protect against severe
impact hazards, explosions or corrosive liquids. Machine guards
or eye splash protection must be used when these hazards are
present.
WARNING! Using filter forms from any other manufacturer’s welding
mask can seriously impaired the protection provided and may result
in serious personal injury.
1. Use the correct tool for the job. This welding mask was designed for a
specific function. Do not modify or alter this welding mask or use it for
an unintended purpose.
2. Do not use the tool if any parts are damaged, broken or misplaced.
Repair or replace the parts.
3. This welding mask is not recommended for overhead welding
applications, laser welding or laser cutting applications.
4. In the event of electronic failure, the filter remains dark at Shade 15
to protect against UV and IR radiation.
5. Use the auto-darkening welding filter with inner and outer cover
lenses. Never open or tamper with the filter cartridge.
6. Ensure the front cover lens is mounted before use. Remove the
protective film.
7. Ensure that the lens is clean and there is no dirt or spatter covering
the four sensors at the front of the filter cartridge.
8. Inspect all parts for signs of wear or damage. Any scratched or
cracked parts should be replaced prior to use.
9. Never place the welding mask on a hot surface.
10. Arc rays can burn both eyes and skin. Arc welding produces
intense visible and invisible (ultraviolet and infrared) rays. Wear a
welding mask fitted with the proper shade to protect your face and
eyes when welding or watching.
11. Check whether welding or grinding mode is chosen before use.
