Safety Notes: The measuring tool produces laser class 2 laser radiation according to IEC 60825-1.This can lead to persons being blinded,do not direct the laser beam at persons or animals and do not stare into the direct or reflected laser beam yourself. Do not allow children to use the KT 3D6 laser measuring tool without supervision. Do not operate the measuring tool in explosive environments,such as in the presence of flammable liquids or gases or duxts. Operation: The 12lines green beam laser level is a precision instrument and should be treated with care.Avoid heavy impact or falling of the measuring tool. After heavy exterior impact on the measuring tool,an accuracy check should alawys be carried out before continuing to work. Switch the measuring tool off during transport. When switching off,the leveling unit,which can be damaged in case of intense movement, is locked.
