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 A THIRD 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 colors.
  • 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.
  • Do not open the battery. There is a risk of short-circuiting.
  • In case of damage and improper use of the battery, vapors may be emitted. The battery can set alight or explode. Ensure the area is well ventilated and seek medical attention should you experience any adverse effects. The vapors may irritate the respiratory system.
  • 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 accident-ally 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.
  • The battery can be damaged by pointed objects such as nails or screwdrivers or by force applied externally. An internal short circuit may occur, causing the battery to burn, smoke, explode or overheat.
  • When the battery is not in use, keep it away from paper clips, coins, keys, nails, screws or other small metal objects that could make a connection from one terminal to another. A short circuit between the battery terminals may cause burns or a fire.
  • Only use the battery with products from the manufacturer. This is the only way in which you can protect the battery against dangerous overload.
  • 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.
  • The measuring tool is equipped with a wireless interface. Local operating restrictions, e.g. in aero planes or hospitals, must be observed.

The Bluetooth® word mark and logos are registered trademarks owned by Bluetooth SIG, Inc. and any use of such marks by Robert Bosch Power Tools GmbH is under license.

  • Caution! When using the measuring tool with Bluetooth®, a fault may occur in other devices and systems, aero planes and medical devices (e.g. pacemakers, hearing aids). Also, damage to people and animals in the immediate vicinity can-not be completely excluded. Do not use the measuring tool with Bluetooth® in the vicinity of medical devices, petrol stations, chemical plants, areas with a potentially explosive atmosphere and in blasting areas. Do not use the measuring tool with Bluetooth® on aero planes. Avoid using the product near your body for extended periods.
