• Do not expose the product to rain or moisture. Penetrating moisture can cause short circuits, electrical shock, burns or explosions.
  
• Wipe the product dry before stowing it in the transport container.
  

• Stay alert, watch what you are doing and use common sense when operating the product. Do not use the product while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating the product can result in serious personal injury.
  
• Avoid unusual body positions. Keep proper footing and balance at all times.
  
• Wear personal protective equipment. Wearing personal protective equipment reduces the risk of injury.
  
• Do not render safety devices ineffective and do not remove information and warning notices.
  
• Avoid accidental starting. Make sure that the product is switched off before inserting batteries and before picking it up or carrying it.
  
• Use the product and accessories in accordance with these instructions and in the way specified for this special type of tool. Take the working conditions and the work to be performed into account. Use of products for applications different from those intended could result in hazardous situations.
  
• Do not allow yourself to be lulled into a false sense of security and do not flout the safety rules, even if you are familiar with the product after using it many times. Caress handling could cause serious injury within fractions of a second.
  
• Do not use the product in proximity to medical devices.
  

• Use the product and accessories only when they are in perfect working order.
  
• Store products out of reach of children when not in use. Do not allow persons who are not familiar with the product or these instructions to operate it. The product is dangerous if used by inexperienced persons.
  
• Maintain the product carefully. Check that moving parts operate satisfactorily and do not jam, and make sure that no parts are broken or damaged in such a way that the product might no longer function correctly. Have damaged parts repaired before using the product. Many accidents are caused by poorly maintained products.
  
• Do not under any circumstances modify or tamper with the product. Changes or modifications not expressly approved by Hilti may restrict the user’s authorization to operate the product.
  
• Check the accuracy of the product before using it for important measurements, and if it has been dropped or subjected to other mechanical stresses.
  
• Due to the measuring principle employed, the results of measurements can be negatively affected by certain ambient conditions. These include, for example, the proximity of devices that produce strong magnetic or electro-magnetic fields, vibrations and temperature changes.
  
• Rapidly changing measuring conditions can falsify the results.
  
• When the product is brought into a warm environment from very cold conditions, or vice-versa, allow it to become acclimatized before use. Big differences in temperature can lead to incorrect operation and incorrect results.
  
• When adapters or accessories are used, make sure they are mounted securely.
  
• The product is designed for the tough conditions of jobsite use, but as with other optical and electrical products (e.g. binoculars, spectacles, cameras) it must be handled with care.
  
• The specified operating and storage temperatures must be observed.

Using laser

1. Press the on/off button to switch the laser beam on.
   
   The laser shuts down automatically if 6 minutes pass without a fastener being driven.
   
2. Turn the selector knob to the desired distance.
   
3. Drive a fastener (see the operating instructions for the fastening tool).
   
4. To drive the next fastener, advance the fastening tool on the working surface to where the laser arc is over the exact center of the fastener driven beforehand.
   
   The correct radius is shown only when the fastening tool is not pressed against the working surface.
   
5. Drive the next fastener.
   
6. Continue repeating steps 3 to 5 until there are no more fasteners you want to drive.
   
7. Press the on/off button to switch the laser off.
   

Checking accuracy

1. Mark a point (with a cross) on a level surface.
   
2. Correctly install the laser on the fastening tool.
   
3. Position the fastening tool with the muzzle centered on the cross marked beforehand.
   
4. Switch the laser on and set it to a distance presetting of 300 mm.
   
5. Apply three more marks on the projected laser circle to the right, left and above the initial mark.
   
6. Switch the laser off and lay the fastening tool aside.
   
7. Now measure the distances between the initial mark and each of the three new marks.
   
   • The deviation of each point should not be more than -15 % to +5 % of 300 mm.
     
   • If deviation is outside this tolerance, consult Hilti Service.
     
8. Repeat steps 4 to 7 for all other radius settings (400 mm, 500 mm, 600 mm and 800 mm).
