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 unrecognisable. 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.
8 | English
▶ Do not make any modifications to the laser equipment.
▶ 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 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.

A) When measuring from the back edge of the measuring tool, this applies for high reflectivity of the target (e.g. a wall painted white), weak background lighting and a 20 °C operating temperature; a distance-dependent deviation of ±0.05 mm/m must additionally be factored in.
B) When measuring from the back edge of the measuring tool, this applies for high reflectivity of the target (e.g. a wall painted white), strong background lighting, 20 °C operating temperature and high elevation. In addition, a deviation of ±0.15 mm/m must be taken into account, depending on the distance.
C) Only non-conductive deposits occur, whereby occasional temporary conductivity caused by condensation is expected.
The serial number (8) on the type plate is used to clearly identify your measuring tool.
Inserting/Changing the Battery
Always replace all the batteries/rechargeable batteries at the same time. Only use batteries/rechargeable batteries from the same manufacturer and which have the same capacity.
When inserting the batteries, ensure that the polarity is correct according to the illustration on the inside of the battery compartment.
▶ Take the batteries out of the measuring tool when you are not using it for a prolonged period of time. The batteries can corrode and self-discharge during prolonged storage.

Operation
Starting Operation
▶ Never leave the measuring tool unattended when switched on, and ensure the measuring tool is switched off after use. Others may be dazzled by the laser beam.
▶ Protect the measuring tool from moisture and direct sunlight.
Do not expose the measuring tool to any extreme temperatures or variations in temperature. For example, do not leave it in a car for extended periods of time. In case of large variations in temperature, allow the measuring tool to adjust to the ambient temperature before putting it into operation. The precision of the measuring tool may be compromised if exposed to extreme temperatures or variations in temperature.
- Avoid substantial knocks to the measuring tool and avoid dropping it. After strong external influences on the measuring tool, you should always carry out an accuracy check (see "Accuracy Check", page 14) before further work.
Switching On and Off
» Press the button to switch on the measuring tool.
» Press and hold the ▲ button to switch off the measuring tool.
If no button on the measuring tool is pressed for approx. 5 min, the measuring tool will switch off automatically to preserve the non-rechargeable batteries.
Measuring Process
When switching on for the first time, the measuring tool will be in the length measurement function. When switching on every subsequent time, the measuring tool will be in the measuring function that was last used.
The rear edge of the measuring tool is always the reference level for the measurement.
» Apply the measuring tool to the point at which you want to start the measurement (e.g. wall).
» Press the ▲ button to switch on the laser beam.
» Target the target surface with the laser beam.
» Briefly press the button again to start the measurement.

The measuring tool must not be moved during a measurement. Therefore, place the measuring tool, as far as this is possible, against or on a firm stop or supporting surface.
The reception lens (10) and the laser beam output (11) must not be covered during the measuring process.
Basic settings
The measuring tool offers the following basic settings:
- Changing the unit of measurement
- Information on the measuring tool
– QR code for the online operating manual - Reset to factory settings
– Licence Texts and Legal Notes
