When exceeding the maximum permitted operating temperature of 40 °C,
the laser tool switches off to protect the laser diode. After cooling down,
the laser tool is ready for operation and can be switched on again.
The laser tool switches off automatically after an operating duration of 30
minutes. To deactivate the automatic switch-off, keep the operating mode
button 4 pressed for 3 s while switching on the laser tool. When the
automatic switch-off is deactivated, the laser lines briefly flash after
3 s.
To activate the automatic shut-off, switch the laser tool off and then on
again (without the operating mode button 4 pushed).
The laser tool has four operating modes, between which you can switch
at any time:
– Horizontal operation (operating mode A): generates a horizontal laser
line.
– Cross-line operation (operating mode B): generates a horizontal and a
vertical laser line.
– Vertical operation (operating mode C): generates two vertical, orthogonal
laser lines,
– Horizontal operation combined with vertical operation (operating mode
D): generates a horizontal and two vertical laser lines..
In all operating modes, a plumb down point is projected onto the floor.
Once switched on, the laser tool is in operating mode "D". To change the
operating mode, press the operating mode button 4.
All four operating modes can be selected with or without self leveling.
In cross-line and vertical operation, the vertical lines can be aligned exactly
on a reference object using the fine adjustment knob 18.
When working with the laser receiver 26, the pulse function must be
activated, – independent of the selected operating mode.
In pulse function, the laser lines flash at very high frequency (invisible to
the human eye) and thus becomes detectable by the laser receiver 26.
