Initial Operation
Protect the tool against

WARNING
moisture and direct sun
irradiation.
• Do not subject the tool to extreme
temperatures 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 tool to
adjust to the ambient temperature before
putting it into operation. In case of extreme
temperatures or variations in temperature,
the accuracy of the tool can be impaired.
• Avoid heavy impact or falling of the
tool. After heavy exterior impact on the
tool, an accuracy check should always be
carried out before continuing to work (see
"Leveling Accuracy").
• Switch the tool off during transport.
When switching off, the leveling unit,
which can be damaged in case of intense
movement, is locked.
Switching On and Off
To switch on the tool, slide the On/Off switch 7
to the "

leveling unit is locked.
Deactivating the Automatic Shut-off: The 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

Operation
To activate the automatic shut-off, switch the
tool off and then on again (without the
operating mode button 4 pushed).
Operating Modes (see figures A–D)
The tool has three operating modes between
which you can switch at any time:
– Horizontal operation "–": Produces a
– Vertical operation "l": Produces a vertical
– Cross-line operation "+": Produces a
All three operating modes can be selected in
the automatic leveling mode. In the locked
mode, either the horizontal operation or the
vertical operation mode can be selected.
After switching on, the tool is in cross-line
operating mode. To change the operating
mode, press the operating mode button 4.
Pulse Function
The LR2 laser receiver allows the GLL2-45 to
be used in situations in which the lines cannot
be seen. The pulse function is activated
separately from the selection of the operating
mode. The GLL2-45 does not work with other
laser receivers.

In pulse function, the laser lines flash at very
high frequency (invisible to naked eye) and
thus become detectable for the laser
receiver 16.
To switch on the pulse function, press button
3. When the pulse function is switched on, the
pulse-function indicator 2 lights up green.
When the pulse function is switched on, the
visibility of the laser lines is reduced for the
human eye. Therefore, shut off the pulse
function by pushing button 3 again when
working without laser receiver. When the pulse
function is switched off, the pulse-function
indicator 2 is deactivated.
Automatic Leveling

Position the tool on a level and firm support or
attach it to a 1/4" thread tripod.
