Switching On/Off
To switch on the measuring tool, slide the on/off switch (4) to the ON position. Immedi-
ately after switching on, the measuring tool sends a laser line out of the outlet
aperture (5).
Do not direct the laser beam at persons or animals and do not stare into the laser
u
beam yourself (even from a distance).
To switch off the measuring tool, slide the on/off switch (4) 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
u
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 oper-
ating 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.
Deactivating the Automatic Shut-Off Function
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 (4) to the OFF position first and then switch the meas-
uring tool back on, or press one of the laser mode buttons (1).
To deactivate the automatic shut-off function, hold down one of the laser mode
buttons (1) 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.
Operating Modes
The measuring tool can generate one horizontal and two vertical laser lines.
Once the measuring tool is switched on, the horizontal laser line is switched on.
You can switch each of the laser lines on and off independently of one another. To do
this, press the laser operating mode button (1) that corresponds to the relevant laser
line.
All operating modes can be used with both automatic levelling and the incline function.
All operating modes are suitable for operation with the laser receiver (23).
