OPERATION

ON/OFF. The button (1) is used to turn the device on and off. The LED (2) lights up red when the device
is turned on and will start flashing when the battery level is low - the batteries should be charged or
replaced.
Automatic self-leveling. After turning on the laser, it will automatically go into the self-leveling mode -
the laser beams will start blinking. Fast blinking of the LED (4) and the laser beams means that the
device is outside the self-leveling range of ±5°; you need to manually adjust the device. When the level
is reached, the rotation will start automatically.
Manual mode (for determining slopes). In order to turn off the self-leveling and switch to the manual
mode, press the button (5) until LED (4) lights up.
Rotation speed. After turning on the device, it will automatically start up at a speed of 600 rpm.
Pressing the button (6) will change the speed successively to 0-60-120-300-600-0 rpm.
Tilt alarm (TILT). It is a function that can be activated to prevent automatic return to level after losing it
from a predetermined position, where it would self-level with a possible change in the height of the
setting. To activate the tilt alarm function, press the button (7) - the diode (3) will start flashing slowly,
confirming operation with the tilt alarm. After the laser's position is interrupted, the beam will stop
rotating and start flashing quickly together with the diode (3). In such a case, the laser must be
switched on manually by pressing the button (7) or by switching the laser off and on again using the
button (1). After restarting, check fi the laser line's altitude is the same as before stopping.
