Safety Notes
Read and observe all instructions. SAVE THESE INSTRUCTIONS FOR
FUTURE REFERENCE.
Have the measuring tool repaired only through qualified specialists using
original spare parts. This ensures that the safety of the measuring tool is main-
tained.
Do not operate the measuring tool in explosive environments, such as in the
presence of flammable liquids, gases or dusts. Sparks can be created in the
measuring tool which may ignite the dust or fumes.
Keep the measuring tool away from cardiac pacemakers. The
magnet plate 5 generates a field that can impair the function of car-
diac pacemakers.
Keep the measuring tool away from magnetic data medium and magnetically-
sensitive equipment. The effect of the magnet plate 5 can lead to irreversible da-
ta loss.

Noise Information
The A-weighted sound pressure level of the audio signal at one meter distance
is 80 dB(A).
Do not hold the measuring tool close to your ear!
Assembly
Inserting/Replacing the Battery
Alkali-manganese batteries are recommended for the measuring tool.
Pull the latch 11 of battery lid outward and open the battery lid 13.
When inserting the battery, pay attention to the correct polarity according to the rep-
resentation on the inside of the battery compartment.
When the battery low indicator e appears for the first time on the display 4, the meas-
uring tool can still be operated for approx. 2 h.
If the measuring tool is not used for a long period of time, the battery must be
removed. The battery can corrode or discharge itself over long periods.

Operation
Initial Operation
Protect the measuring tool against moisture and direct sun light.
Do not subject the measuring tool to extreme temperatures or variations in
temperature. As an example, do not leave it in vehicles for long time. In case of
large variations in temperature, allow the measuring 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 measuring tool can be impaired.
Setting Up the Measuring Tool (see figure A)
Position the measuring tool at least 5 m away from the cross-line laser. Switch on the
pulsating function on the cross-line laser, and select horizontal or vertical operation.
Note: Do not select cross-line operation, as otherwise faulty indications on the height
of the laser beam can occur.
Position the measuring tool in such a manner that the laser beam can reach the recep-
tion area 10. Align the measuring tool in such a manner that the laser beam runs lat-
erally through the reception area (as shown in the figure).
Switching On and Off
A loud audio signal sounds when switching on the measuring tool. Therefore,
keep the measuring tool away from your ear or other persons when switching
on. The loud audio signal can cause hearing defects.
To switch on the measuring tool, press the On/Off button 2. All display indicators as
well as all LEDs light up briefly and an audio signal sounds.
To switch off the measuring tool, press the On/Off button 2 again. Before switching
off, all LEDs briefly light up.
When no button is pressed on the measuring tool for approx. 20 minutes and when no
laser beam reaches the reception area 10 for 20 minutes, the measuring tool auto-
matically switches off in order to save the battery. The switching off is indicated by
brief lighting up of all LEDs.
Selecting the Setting of the Centre Indicator
With button 1, you can specify with which accuracy the position of the laser beam is
indicated as central on the reception area:
– “Fine” adjustment (indication g on the display),
– “Coarse” adjustment (indication f on the display).
Whenever switching on the measuring tool, the accuracy level “coarse” is set.

Direction Indicators
The position of the laser beam on the reception area 10 is indicated:
– via the direction indicators “move downward” d, “move upward” b or the centre in-
dicator c on the display 4 on the front and back side of the measuring tool,
– via the LEDs “move downward” 6, “move upward” 9 or the centre-indication LED 7
on the front side of the measuring tool,
– optionally via the audio signal (see “Audio Signal for Indication of the Laser Beam”,
page 17).
Measuring tool too low: When the laser beam runs through the top half of the recep-
tion area 10, the direction indicator b on the display and the corresponding direction
LED 9 light up.
When the audio signal is switched on, a slow-beat signal sounds.
Move the measuring tool upward in the direction of the arrow.
Measuring tool too high: When the laser beam runs through the bottom half of the
reception area 10, the direction indicator d on the display and the corresponding di-
rection LED 6 light up.
When the audio signal is switched on, a fast-beat signal sounds.
Move the measuring tool downward in the direction of the arrow.
Measuring tool in centre position: When the laser beam runs through the reception
area 10 at the centre mark 8, the centre indicator c on the display and the corre-
sponding centre-indication LED 7 light up. When the audio signal is switched on, a
continuous signal sounds.
Audio Signal for Indication of the Laser Beam
The position of the laser beam on the reception area 10 can be indicated via an audio
signal.
After the measuring tool has been switched on, the audio signal is always set to the
low volume level.
The volume level can be increased or switched off.
To change the volume level or switch off the audio signal, push the acoustic signal but-
ton 3 until the requested volume level is indicated on the display. At low volume level,
the audio signal indicator a appears on the display with one bar; at high volume level,
the indicator appears with three bars. When the audio signal is set to off, the indicator
goes out.
Independent of the audio signal setting, a short beep sounds at low volume level each
time a button is pressed on the measuring tool.

Working Advice
Marking
When the laser beam runs through the center of the reception area 10, its height can
be marked at the centre mark 8 right and left on the measuring tool.
When marking, take care to align the measuring tool exactly vertical (for horizontal
laser beam), or horizontal (for vertical laser beam), as otherwise the marks are offset
with respect to the laser beam.
Attaching with the Magnet (see figure B)
When a positive-lock attachment is not absolutely required, the measuring tool can be
attached to steel parts via the face side using the magnet plate 5.
Maintenance and Service
Maintenance and Cleaning
Keep the measuring tool clean at all times.
Do not immerse the measuring tool in water or other fluids.
Wipe off debris using a moist and soft cloth. Do not use any cleaning agents or sol-
vents.
If the measuring tool should fail despite the care taken in manufacturing and testing
procedures, repair should be carried out by an authorised after-sales service centre
for Bosch power tools. Do not open the measuring tool yourself.
In all correspondence and spare parts orders, please always include the 10-digit
article number given on the type plate of the measuring tool.
