- Check the light transmittance specifications of the filter in the specification sheet.
- People working in areas where there is a risk of exposure to laser radiation must wear laser protection device.
- The light transmittance of the lens is less than 20%, the light at the workplace must be increased when using this eyewear.
- The recognition of warning lights or warning signals can be impaired because of the color filters.
- Do not use this eye protection device while driving, engaging in recreation or sports activities or any other activities that they are not designed for.
- Keep these instructions with a protective device
- Please refer to the user manual for technical information and performance of the eye protection device you own.
- Filters shall not be interchangeable in the frame. They are only used for the laser welding helmet.
- Filters in the laser welding helmet against laser radiation shall not be exchanged by non-professionals.
Unauthorized modifications and replacement parts will void the warranty and expose the user to the risk of personal injury.
