Operation
Starting Operation of the Rotational Laser Level
Protect the measuring tool against moisture and direct
sun light.
Do not subject the measuring tool to extreme tempera-
tures or variations in temperature. As an example, do
not leave it in vehicles for longer periods. In case of large
variations in temperature, allow the measuring tool to ad-
just to the ambient temperature before putting it into oper-
ation. In case of extreme temperatures or variations in
temperature, the accuracy of the measuring tool can be im-
paired.
Avoid heavy impact to or dropping down of the measur-
ing tool. After severe exterior effects to the measuring
tool, it is recommended to carry out an accuracy check
(see "Levelling Accuracy of the Rotational Laser Level",
page 25) each time before continuing to work.
Setting Up the Measuring Tool
Horizontal position
Vertical position
Set up the measuring tool on a sturdy surface in the horizontal
or vertical position; mount it on a tripod 37 or to the wall
mount with alignment unit 39.
Due to the high levelling accuracy, the measuring tool reacts
sensitively to ground vibrations and position changes. There-
fore, pay attention that the position of the measuring tool is
stable in order to avoid operational interruptions due to re-
levelling.
Switching On and Off
Do not direct the laser beam at persons or animals (es-
pecially not at their eye level), and do not stare into the
laser beam yourself (not even from a distance). Imme-
diately after switching on, the measuring tool sends out the
vertical plumb beam 9 and the variable laser beam 6.
For switching on the measuring tool, press the On/Off button
4. The indicators 1, 3 and 12 light up briefly. The measuring
tool immediately starts the automatic levelling. During the lev-
elling, the levelling indicator 3 lights up green and the laser
flashes in point operation.
The measuring tool is levelled in as soon as levelling indicator
3 lights up green continuously and the laser beam is steady.
After the levelling is completed, the measuring tool automati-
cally starts in rotational operation.
With the operating mode buttons 5 and 11, the operating
modes can already be specified during levelling in (see "Oper-
ating Modes of the Rotational Laser Level", page 23). In this
case, the measuring tool starts in the set operating mode up-
on completion of levelling in.
To switch off the measuring tool, press the On/Off button 4
again.
Bosch Power Tools
Do not leave the switched on measuring tool unattend-
ed and switch the measuring tool off after use. Other
persons could be blinded by the laser beam.
To save the batteries, the measuring tool is automatically
switched off when not within the self-levelling range for more
than 2 h or when the shock warning is actuated for more than
2 h (see "Automatic Levelling of the Rotational Laser Level",
page 24). Reposition the measuring tool and switch it on again.
Starting Operation of the Remote Control
Protect the remote control against moisture and direct
sunlight.
Do not subject the remote control to extreme tempera-
tures or variations in temperature. As an example, do
not leave it in vehicles for longer periods. In case of large
variations in temperature, allow the remote control to ad-
just to the ambient temperature before putting it into oper-
ation.
The remote control remains ready for operation as long as a
battery with sufficient voltage is inserted.
Set up the measuring tool in such a manner that the signals of
the remote control can directly reach one of the reception
lenses 7. When the remote control cannot be pointed directly
against a reception lens, the working range is reduced. By re-
flecting the signal (e.g. against walls), the working range can
be improved, even for indirect signals.
After pressing a button on the remote control, the illuminated
operation indicator 30 indicates that a signal was sent out.
Switching the measuring tool on/off with the remote control is
not possible.
Operating Modes of the Rotational Laser Level
Overview
All three operating modes are possible with the measuring
tool in horizontal and vertical position.
Rotational Operation
Rotational operation is especially recom-
mended when using the laser receiver.
You can select between different rota-
tional speeds.
Line Operation
In this operation mode, the variable laser
beam moves within a limited aperture an-
gle. This increases the visibility of the la-
ser beam in comparison to rotational op-
eration. You can select between different
aperture angles.
Point Operation
This operation mode enables the best vis-
ibility of the variable laser beam. As an ex-
ample, it is used for easy projecting of
heights or checking building lines.
