Cleaning And Disinfecting - Telwin TW3000 Handbuch

• The filter does not darken or is unstable when switching from light to dark and viceversa.
Possible solution.
- The external transparent protection of the filter is dirty or damaged (change the external transparent protection).
- The sensors are dirty (clean the sensor surface).
- The level of the welding current level is too low for the "shade 11" protection level of this mask (replace the mask with another one having a suitable
filter)
• Slow switching.
The operating temperature is too low (do not use at temperatures of below -5°C (+23°F).
• Poor visibility.
- The external or/and internal protection of the filter is/are dirty or damaged (clean the dirty components and replace the damaged ones).
- Not enough light in the surrounding area (add more light to the surrounding area)
- The welding current intensity is too low for the "shade 11" level of this mask (replace the mask with another one fitted with a suitable filter)
ATTENTION!
If the described malfunctions cannot be solved, stop using the mask immediately and contact the nearest distributor.

CLEANING AND DISINFECTING

• Only use soap and water or products that do not contain solvents to clean and disinfect the mask. Using chemical solvents ruins the aesthetics of the
mask and can dramatically reduce its integrity.
• Taking good general care of the mask reduces its obsolescence to a minimum, both from a use and a mask component point of view.
• Regularly clean the filter surface with a soft cloth and a non-aggressive cleaning solution, for example one for cleaning glass (do not pour the product
directly onto the filter).
• Get into the habit of making sure that the solar cells and the sensors have not darkened or are not covered in dirt. If they have or if they are, clean them
with a soft paper tissue, if necessary slightly dampened with a preparation for cleaning glass (do not pour the product directly onto the filter).
ASSEMBLY
