Bosch GLL 150 E Operating/Safety Instructions Manual page 12

The Bosch Electronic Laser Line Detector aids in locating and targeting a visible or invisible beam
emitted by a Pulsed Line laser; perfect for use in outdoor conditions, where sunlight and distance
may make locating the beam more difficult. The laser detector includes a rod clamp which allows to
mount the detector onto square, round or oval leveling rods.
The numbering of the product features shown
refers to the illustration of the tool on the graphic
page 11 (Fig. 1).

– To attach the rod clamp (fig. 6 #1) to the
detector, align projections on the rod clamp
with corresponding recess on the back of
the detector, and tighten the knob (fig. 6
#2). To detach rod clamp (fig. 6 #1) from
the detector, unscrew the knob (fig. 6 #2)
completely.
– To attach the rod clamp (fig. 6 #1) to
leveling rod 14, loosen the knob (fig. 6 #3)
on the rod clamp (fig. 6 #1), slide the rod
clamp on the leveling rod 14 to the desired
location, and tighten the knob (fig. 6 #3).
The spirit level (fig. 6 #4) can be used to
approximately level the leveling rod. Adjust
the position of the leveling rod until the
bubble in the spirit level (fig. 6 #4) is within
the circle.
Wear eye protection. If the

spirit level leaks, soak up
with appropriate absorbent material and
dispose of safely. The spirit level contains
flammable liquid that may cause respiratory
tract, eye and skin irritation.
Introduction
LR 3 Features
15 Level Beam
16 Low Battery Indicator
Power
Two AA batteries will provide up to 30 hours of
continuous use. When the instrument is turned
on and the low battery symbol remains lit, the
battery should be replaced.
Installing and Removing Batteries
To replace batteries, detach the rod clamp (fig.
6 #1) from the detector by turning the knob (fig.
6 #2) on the rod clamp. Open the battery door
(fig. 1 #8) by pulling latch.
Install batteries with correct polarity as indicated
in the battery compartment. Close the battery
door and engage the latch.
LR 3 Operation
– Turn on the instrument by pressing the
ON/OFF button on the keypad. The LCD
symbols will momentarily be lit and the
unit will beep once. The Coarse bandwidth
indicator and soft volume indicator will
remain lit.
– Expose the beam capture window of the
laser detector towards the direction of the
pulsed laser line.
– Slowly move the laser detector in an upward
and downward direction until the LCD beam
indicator arrows appear and/or a pulsing
audio signal is heard. Use the Bandwidth
Resolution Selection feature to choose
between the Fine/Coarse setting. Coarse
resolution setting is for approximating level
or for initial locating of the center level point.
Fine resolution setting is used for most
accurate pin pointing of level.
– Move the detector upward when the bottom
arrow icon is lit (fig. 5) (with volume on, a
slow pulsing audio tone is heard). Move the
detector downward when the top arrow icon
