Do not allow children to use the laser measuring tool 

without supervision. 

They could unintentionally blind other 

persons or themselves.

Do not use the laser viewing glasses as safety goggles or 

in traffic. 

The laser viewing glasses are used for improved 

visualisation of the laser beam, but they do not protect against 

laser radiation.

Have the measuring tool repaired only through qualified 

specialists using original spare parts. 

This ensures that the 

safety of the measuring tool is maintained.

Do not make any modifications to the laser equipment.

Do not direct the laser beam at persons or animals 

and do not stare into the direct or reflected laser 

beam yourself, not even from a distance. You could 

blind somebody, cause accidents or damage your 

eyes.
