Working Advice

Working with the Tape Measure

The zero point of the tape measure (10) is situated in the centre of the marking aid (20), it can be marked directly on the substrate.

Note: The zero point marking can be offset by up to ±1 mm compared to the laser line.

Pull the tape measure housing (11) away from the measuring tool and mark additional points at the required distances at the height of the laser line.

Do not pull the tape measure (10) out any further than up to the end of the imprinted scale. You can double the work area by placing the measuring tool in the middle of the work surface and measuring on two sides one after the other.

If the tape measure is not locked, it will roll itself up again automatically.

Note: Do not let go of the unrolled tape measure (10) (unless it's secured with the locking mechanism (12)). Uncontrolled retraction may damage the tape measure.

Locking the tape measure:
To lock the pulled-out tape measure (10), press the locking mechanism (12) of the tape measure down. To release the tape measure again, press the locking mechanism up.

Removing/inserting the tape measure:
To remove the tape measure (10) from the measuring tool, press the unlocking lever (3) and lift the end of the tape measure out of the measuring tool.
To insert the tape measure (10) into the measuring tool, press and hold the unlocking lever (3). Insert the end of the tape measure into the recess under the unlocking lever and let go of the unlocking lever.

Calibrating the Laser Line

Calibration should be carried out in the following cases:

• After the tool has been dropped or subjected to heavy impact
• Every 6 months

If necessary, check the levelling of the laser line on a known horizontal or vertical reference line.

Always perform a thorough and complete calibration to avoid incorrect measuring results.

• Attach the measuring tool to a vertical surface.
• While the measuring tool is either switched on or off, press the on/off button (1) for at least 3 s until the laser beam starts flashing and the light-up ring (2) is no longer lit.
• Slowly and evenly rotate the housing of the measuring tool once by more than 360°. The rotation should take at least 15 s.
• The calibration process is completed successfully once the light-up ring (2) lights up green.
• If the light-up ring (2) lights up red after calibration, the calibration has failed. Restart the calibration.
