ent temperature before putting it into operation. The precision of the measuring tool
may be compromised if exposed to extreme temperatures or variations in temperat-
ure.
Avoid substantial knocks to the measuring tool and avoid dropping it. Damaging
u
the measuring tool can cause accuracy to be compromised. If the laser line is subjec-
ted to a substantial knock or is dropped, check it by comparing it to a known hori-
zontal or vertical reference line.
Switch the measuring tool off when transporting it. The pendulum unit is locked
u
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 (4) to the ON position. Immedi-
ately after switching on, the measuring tool sends laser lines out of the front and upper
outlet aperture (6).
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.
Operating Modes
The measuring tool has several operating modes, which you can switch between at any
time:
– Cross-line operation (see figure A): The measuring tool generates a horizontal laser
plane (360° circumferential laser line) and a vertical laser line pointing forwards,
– Cross-line and plumb point mode (see figure B): Generates a horizontal laser plane
(360° circumferential laser line), two vertical, orthogonal laser lines as well as a
plumb point below,
– Horizontal mode (see figure C): Generates a horizontal laser plane (360° circumferen-
tial laser line).
Once the measuring tool has been switched on, it is in cross-line operation with auto-
matic levelling. To change the operating mode, press the laser mode button Mode (1).
All operating modes can be used with both automatic levelling and the incline function.
