• Precautions must be taken to ensure that persons do not stare directly into the beam.
  
• The laser beam must not be allowed to project beyond the controlled area.
  
• Switch the laser tool off when it is not in use.
  
• Store laser tools, when not in use, in places to which unauthorized persons have no access.
  

Proper arrangement of the workplace

• Avoid unusual postures when working on ladders. Maintain firm footing and balance at all times.
  
• Secure the site where you are taking measurements and when using the product do not direct the laser beam toward other persons or toward yourself.
  
• When the product is brought into a warm environment from very cold conditions, or vice-versa, allow it to become acclimatized before use.
  
• Use the product only within its specified limits.
  
• Keep the laser aperture clean to avoid measurement errors.
  
• Comply with the national accident prevention regulations.
  

Electromagnetic compatibility

Although the product complies with the strict requirements of the applicable directives, Hilti cannot entirely rule out the possibility of interference to the product caused by powerful electromagnetic radiation, possibly leading to incorrect operation. Check the accuracy of the device by taking measurements by other means when working under such conditions, or if you are unsure. Likewise, Hilti cannot rule out the possibility of interference with other devices (e.g. aircraft navigation equipment). The product complies with the requirements of class A; the possibility of interference in a residential environment cannot be excluded.
Only for Korea: This laser range meter is suitable for commercial and industrial use and for the electromagnetic radiation encountered in this field (Class A). The user must be aware of this and shall not use this laser range meter in residential environments.
