Product Information
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.
- 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. Product Description and Specifications

- 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) In continuous measurement mode, the max. operating temperature is +40 °C.
- D) Only non-conductive deposits occur, whereby occasional temporary conductivity caused by condensation is expected.
The serial number (9) 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 19) before further work.
Switching On and Off
- Press the button to switch the measuring tool and the laser on.
- You can also switch on the measuring tool without the laser by pressing the button.
- Press and hold the button to switch off the measuring tool.
The measured values and device settings in the memory are retained. All stored values are retained when the tool is switched off.
Measuring Process
Once switched on, the measuring tool is in the length measurement function.
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).
- If you have switched on the measuring tool with the button then briefly press the button to switch on the laser.
- Press the button to start the measurement.
- Once the measurement process is complete, the laser beam will switch off. For a further measurement, repeat this process.
- Measured values or end results can be added or subtracted.
- In the continuous measurement function, the measurement begins immediately upon switching on the function.
- For more information, you can access the online operating instructions at
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 (11) and the laser beam output (12) must not be covered during the measuring process.
Basic settings
The measuring tool offers the following basic settings:
- Changing the unit of measurement
- Switching audio signals on and off

Error Message
- If a measurement cannot be performed correctly, the error message will appear in the display.
- Try to perform the measuring process again.
- If the error message appears again, switch the measuring tool off and back on, and start the measurement again.
The measuring tool monitors correct operation in every measurement. If a defect is detected, all indicators on the display will flash. In this case, or if you are unable to rectify an error using the corrective measures, send the measuring tool to the Bosch after-sales service via your dealer.
Maintenance and Service
Maintenance and Cleaning
Keep the measuring tool clean at all times. Never immerse the measuring tool in water or other liquids. Wipe off any dirt using a damp, soft cloth. Do not use any detergents or solvents. Take particular care of the reception lens (11), which must be handled with the same level of care you would give to a pair of glasses or a camera lens.
