Safety Instructions

All instructions must be read and observed in order for the measuring tool to function safely. The safeguards integrated into the measuring tool may be compromised if the measuring tool is not used in accordance with these instructions.  Never make warning signs on the measuring tool unrecognizable. SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCE AND INCLUDE THEM WITH THE MEASURING TOOL WHEN TRANSFERRING IT TO ATHIRD PARTY.

• Warning! If operating or adjustment devices other than those specified here are used or other procedures are carried out, this can lead to dangerous exposure to radiation.
• The measuring tool is delivered with a laser warning sign (marked in the illustration of the measuring tool on the graphics page).
• If the text of the laser warning label is not in your national language, stick the provided warning label in your national language over it before operating for the first time.
  Do not direct the laser beam at persons or animals and do not stare into the direct or reflected laser beam yourself. You could blind somebody, cause accidents or damage your eyes.
• If laser radiation hits your eye, you must close your eyes and immediately turn your head away from the beam.
• Do not make any modifications to the laser equipment.
• Do not use the laser goggles (accessory) as protective goggles. The laser goggles make the laser beam easier to see; they do not protect you against laser radiation.
• Do not use the laser goggles (accessory) as sunglasses or while driving. The laser goggles do not provide full UV protection and impair your ability to see colours.
• Have the measuring tool serviced only by a qualified specialist using only original replacement parts. This will ensure that the safety of the measuring tool is maintained.
• Do not let children use the laser measuring tool unsupervised. They could unintentionally blind themselves or other persons.
• Do not use the measuring tool in explosive atmospheres which contain flammable liquids, gases or dust. Sparks may be produced inside the measuring tool, which can ignite dust or fumes.
• If used incorrectly or if the battery is damaged, flammable liquid may be ejected from the battery. Contact with this liquid should be avoided. If contact accidentally occurs, rinse off with water. If the liquid comes into contact with  your eyes, seek additional medical attention. Liquid ejected from the battery may cause irritation or burns.
• Only charge the batteries using chargers recommended by the manufacturer. A charger that is suitable for one type of battery may pose a fire risk when used with a different battery.
  Protect the measuring tool against heat, e.g. including prolonged sun exposure, fire, water, and moisture.
  Danger of explosion.
• The measuring tool is equipped with a wireless interface. Local operating restrictions, e.g. in aero planes or hospitals, must be
  observed.
