Starting Operation
- Protect the measuring tool from moisture and direct sunlight.
- Do not expose the measuring tool to any extreme temperatures or fluctuations in temperature. For example, do not leave it in a car for extended periods of time. If it has been subjected to significant fluctuations in temperature, first allow the measuring tool to adjust to the ambient temperature and then always carry out an accuracy check before continuing work see Accuracy Check of the Measuring Tool.
The precision of the measuring tool may be compromised if exposed to extreme temperatures or fluctuations in temperature.
- Avoid substantial knocks to the measuring tool and avoid dropping it. Always carry out an accuracy check before continuing work if the measuring tool has been subjected to severe external influences see Accuracy Check of the Measuring Tool.
- Switch the measuring tool off when transporting it. The pendulum unit is locked when the tool is switched off, as it can otherwise be damaged by big movements.
Switching On/Off
To switch on the measuring tool, slide the on/off switch (3) to the ON position. As soon as it is switched on, the measuring tool emits laser beams from the outlet apertures (4).
- Do not direct the laser beam at persons or animals and do not stare into the laser beam yourself (even from a distance).
To switch off the measuring tool, slide the on/off switch (3) to the OFF position. The pendulum unit is locked when the tool is switched off.
- Never leave the measuring tool unattended when switched on, and ensure the measuring tool is switched off after use. Others may be blinded by the laser beam.
If the temperature of the measuring tool is approaching the maximum permissible operating temperature, the laser lines will gradually become dimmer.
If the maximum permitted operating temperature is exceeded, the laser lines will flash rapidly before the measuring tool switches off. Once it has cooled down, the measuring tool is operational again and can be switched back on.
Automatic shut-off
If no button on the measuring tool is pressed for approx. 120 min, the measuring tool will automatically switch itself off to preserve battery life.
To switch the measuring tool back on after it has been automatically switched off, you can either slide the on/off switch (3) to the "OFF" position first and then switch the measuring tool back on, or press the laser operating mode button (2).
To deactivate the automatic shut-off function, hold down the laser mode button (2) for at least 3 s (with the measuring tool switched on). If the automatic shut-off function is deactivated, the laser beams will flash briefly as confirmation.
To activate the automatic shut-off function, switch the measuring tool off and on again.
