Initial Operation
An accuracy check should always be carried
out before use.
Protect the tool against
moisture and direct
sun light.
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 dropping 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 2
to the “on”. position. Immediately after switching
on, the tool sends laser beams out of the exit
opening 1.
Align arrow of ON-OFF
switch directly below
ON position. If ON -OFF switch is not fully
engaged, self-leveling feature is not activated
and laser line will be out of level.
To switch off the tool, slide the On/Off switch
2 to the “off” position. When switching off, the
leveling unit is locked.
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.
Do not leave the switched on tool
unattended and switch the tool off after use.
Operating Modes
The tool has two operating mode:
- Horizontal operation: generates a self-
leveled, horizontal plane that's pulsed. The
LR 3 laser receiver can be used.
- Slope operation: generates a sloped
plane for indoor work at an angle. Pulse
is deactivated and the LR 3 laser receiver
cannot be use
Pulse Function
To work with the laser receiver 10, the pulse
function is activated when using the tool in
horizontal operation.
With the pulse function, the laser lines flash
at very high frequency and thus become
detectable by the laser receiver 10.
Automatic Leveling
Working with Automatic Leveling
Position the tool on a level and firm support,
such as the BT 152 tripod 13.
Push the On/Off switch 2 to the “on” position.
After switching on, the leveling function
automatically compensates irregularities within
the self-leveling range of ±4°. The leveling is
finished as soon as the laser beams do not
move any more.
If automatic leveling is not possible, e.g.
because the surface on which the tool stands
deviates by more than 4° from the horizontal
plane, the laser lines begin to flash.
Set up the tool in level position and wait for the
self-leveling to take place. As soon as the tool
is within the self-leveling range of ±4°, the laser
beam lights up continuously.
In case of ground vibrations or position changes
during operation, the tool is automatically
re-leveled. To avoid errors, check the position
of the horizontal laser line with regard to the
reference point upon releveling.
Working without Automatic
Leveling
Tilt the unit so the line is projected at the angle
you need it. The laser will flash for the first 30 s
until it turns into a solid line.
Working Advice
Always use the center of
the laser beam for marking.
The thickness of the laser line changes with the
distance.

Working with the laser target plate
The laser target plate 9 increases the visibility
of the laser beam under unfavourable
conditions and at large distances.
The reflective part of the laser target plate 9
improves the visibility of the laser line. Due to
transparency, the laser line is also visible from
the back side of the laser target plate.
Working with the Tripod
A tripod offers a stable, height-adjustable
measuring support. Position the tool with either
the 1/4-20 tripod mount 4 onto the thread of
a commercially available camera tripod or the
preferred method is to mount to a construction
tripod, use the 5/8-11 tripod mount 3. Tighten
the tool with the tripod mounting stud.
Laser Viewing Glasses (Optional
Accessory)
The laser viewing glasses filter out the ambient
light. This makes the red light of the laser
appear brighter for the eyes.
Do not use the laser
viewing glasses as safety
goggles. The laser viewing glasses are used
for improved visualization of the laser beam, but
they do not protect against laser radiation.
Do not use the laser viewing glasses as sun
glasses or in traffic. The laser viewing glasses
do not afford complete UV protection and
reduce color perception.
Work Examples (see figures A–G)
Applicational examples for the tool can be
found on the graphics pages.
Use with Attachments
!
WARNING
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 working
at distances exceeding 65 ft (20 m). If possible,
also set up the tool in the center 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.
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 Horizontal Leveling Accuracy.
A free measuring distance of 16 ft (5 m)on a
firm surface in front of two walls A and B is
required for the check.
– Mount the tool onto a tripod, or place it on
a firm and level surface close to the wall A.
Switch the tool on.
– Direct the laser against the close wall A and
allow the tool to level in. Mark a point on
both walls where the laser indicates (point
y). Mark the center of the laser beam on the
wall (at point y and point z).
– Turn the tool around by 180°, allow it to level
in. The laser line should indicate the same
point within product specification tolerances.

Introduction
LR 3 Features
LR 3 Operation
!
WARNING
-13-
The design of the LR 3 detector is an innovation
to the market. The detector can be switched
between standard and long range modes
enabling extended distance capabilities for the
GLL 150 E and reducing the issue with “scatter”
associated with close in use of line lasers.
When used with the GLL 150 E exterior laser,
the LR 3 receiver enables the instrument to be
used in a work area up to 530 feet (160 m) in
diameter. In standard mode the GLL 150 E and
LR 3 combination will have the elliptical pattern
typical of cone lasers with a maximum range
radius of 196 feet (60 m) along the X-axis and
a minimum range raduis of 65 feet (20 m) along
the Y-axis. Long range mode enables a 265
feet (80 m) circular radius working area.
The area designated by the DASHED circle is
the work area in LONG RANGE MODE.
The area designated by the DOTTED ellipsoid
is the work area in STANDARD RANGE
MODE.
Extended Range Function
The LR 3 receiver defaults to and should be
used in its standard operating mode for most
leveling projects. If the operator is having
difficulty receiving a reading at extended
distances (greater than 65 ft or 20 meters),
indicated by difficulty in locating the center bar
then the extended range button (fig. 1 #10) on
the detector can be pressed and the LED will
be illuminated (fig. 1 #9).
Close Proximity Use
When using the LR 3 in close proximity to the
laser (3ft to 15ft) care must be taken due to the
high sensitivity of the LR 3 and the scatter from
the cone, glass, dust on glass, and surrounding
objects. Close proximity detection should be
validated against reflections and scatter by
ensuring that both the directional arrows are on
either side of the center bar (see fig 3 thru 5).
This can be done by moving the LR 3 up and
down relative to the center bar to locate the
arrows. Do not use the detector closer than 3 ft
from the laser.

If the detector is not struck by a laser beam
after 5 minutes, the detector will automatically
shut itself off to preserve battery life. Turn the
instrument back on using the power button.

Care of Your Laser Detector
LR 3 Special Features
The laser detectors have built in electronic
filtering for bright sunlight and electromagnetic
interference. Three distinct audio patterns
(high, on-grade, and low) assist targeting from
a distance.
The detector LR 3 has three speaker selections
(Off, Soft (~75 dB) and Loud (~85 dB)),
measured at 3 ft (1 meter).
Audio Volume Control
Pressing the volume button (fig. 1 #6) causes
the unit to cycle through volume off, soft
volume, loud volume. After each press, the
speaker will beep once to acknowledge the
button press and demonstrate the volume level.
When the volume is off or soft selected, there
will be one short beep. When the volume is
loud, there will be a loud beep.
