Operation
Initial Operation
•Protect the tool against 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, push the On/Off switch 7 to the “ 
on” position (when working without automatic leveling) or to the “ 
on” position (when working with automatic leveling). Immediately after switching on, the tool sends laser beams out of the exit openings 1.
•Do not point the laser beam at persons or animals and do not look into the laser beam yourself, not even from a large distance.
To switch off the tool, push the On/Off switch 7 to the “off” position. When switching off, 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 switching on the tool. When the automatic switch-off is deactivated, the laser lines briefly flash after 3 s.
•Do not leave the switched on measuring tool unattended and switch the
tool off after use. Other persons could be blinded by the laser beam.
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 horizontal laser line,
–Vertical operation “l”: Produces a vertical laser line,
–Cross-line operation “+”: Produces a horizontal and vertical laser line.
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 GLL2-50 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 GLL2-50 does not work with other laser receivers.
In pulse function, the laser lines flash at very high frequency 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 pulsefunction indicator 2 is deactivated.
Automatic Leveling
Working with Automatic Leveling (see figure C)
Position the tool on a level and firm support or attach it to a commercially available photographic tripod.
When working with automatic leveling, push the On/Off switch 7 to the “ 
on” position.
After switching on, the leveling function automatically compensates irregularities within the self-leveling range of ±4°. The tool is levelled in as soon as the laser lines no longer flash.
-9-
If the automatic levelling function is not possible, e.g. because the surface on which the tool stands deviates by more than 4° from the horizontal plane, the laser beams flash. In this case, bring the tool to the level position and wait for the self-levelling to take place.
In case of ground vibrations or position changes during operation, the tool is automatically levelled in again. To avoid errors, check the position of the horizontal and vertical laser line with regard to the reference points upon re-levelling.
Lock Mode - Working without Automatic Levelling (see figure D)
For work without automatic levelling, push the On/Off switch 7 to the “ 
on” position. When the automatic levelling is switched off, the laser line flash continuously.
When the automatic levelling is switched off, the tool can be held by hand or placed on an inclined surface.
Working Advice
•Always use the center of the laser line for marking. The width of the laser line changes with the distance.
Leveling Accuracy
Influences on Accuracy
The ambient temperature has the greatest influence. Especially temperature differences occurring from the ground upward can divert the laser beam.
Because the largest difference in temperature layers is close to the ground, the tool should always be mounted on a tripod when measuring distances exceeding 65 ft. If possible, also set up the tool in the centre of the work area.
Apart from exterior influences, device specific influences (such as heavy impact or falling down) can lead to deviations. Therefore, check the accuracy of the tool each time before starting your work.
First, check both the height as well as the leveling accuracy of the horizontal laser line, then the leveling accuracy of the vertical laser line.
Should the tool exceed the maximum deviation during one of the tests, please have it repaired by a Bosch
after-sales service center.
Checking the Height Accuracy of the
Horizontal Line
For this check, a free measuring distance of approximately 26 feet on a firm surface between two walls A and B is required.
–Mount the tool onto a tripod or place it on a firm and level surface close to wall A. Switch on the tool. Select cross-line operation with automatic leveling.
A B
26 ft
–Direct the laser against the close wall A and allow the tool to level in. Mark the center of the point where the laser lines cross each other on the wall (point I).
A B 180˚
–Turn the tool by 180°, allow it to level in and mark the cross point of the laser lines on the opposite wall B (point II).
