Sicherheitshinweise

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

24 | English

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.
▶ Do not make any modifications to the laser equipment.
▶ Have the measuring tool repaired 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 modify or open the battery. There is a risk of short-circuiting.
In case of damage and improper use of the battery, vapours 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 vapours 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 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.
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.

Protect the rechargeable battery against heat, e.g. including prolonged sun exposure, fire, water,

26 | English

and moisture. There is a risk of explosion and short circuit.

▶ 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.

» Press and hold the button to switch off the measuring tool.
→ The measured values and device settings in the memory are retained.

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.

Two settings are available for the reference level of the measurement. (see "Reference level", page 34)

» 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.

34 | English

» 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.

The measuring tool must not be moved during a measurement (with the exception of the Min/Max,

Continuous meas. and Tape functions). Therefore, place the measuring tool, as far as this is possible, against or on a firm stop or supporting surface.

The reception lens (14) and the laser beam output (13) must not be covered during the measuring process.

Reference level

For the measurement, you can select from various reference levels:

The rear edge of the measuring tool (e.g. when placing against walls)

The front edge of the measuring tool (e.g. when measuring from a table edge)
