Safety Notes
Read and observe all instructions. SAVE THESE IN-
STRUCTIONS FOR FUTURE REFERENCE.
Keep the measuring tool away from cardiac pace-
makers. The magnet plate 4generates a field that
can impair the function of cardiac pacemakers.
fKeep the measuring tool away from magnetic data medium
and magnetically-sensitive equipment. The effect of the mag-
net plate 4can lead to irreversible data loss.
fHave the measuring tool repaired only through qualified spe-
cialists using original spare parts. This ensures that the safety
of the measuring tool is maintained.
fDo 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.
fRead and strictly observe the safety warnings in the operating
instructions of the rotational laser.

Assembly
Inserting/Replacing the Battery
Alkali-manganese batteries are recommended for the measuring tool.
Press the latch 9of the battery lid outward and open the battery
lid 11.
When inserting the battery, pay attention to the correct polarity ac-
cording to the representation on the inside of the battery compart-
ment.
When the battery indication cappears for the first time on the dis-
play 7, the measuring tool can still be operated for approx. 3 h.
fIf 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
fProtect the measuring tool against moisture and direct sun
light.
fDo not subject the measuring tool to extreme temperatures or
variations in temperature. As an example, do not leave it in ve-
hicles for longer periods. In case of large variations in tempera-
ture, allow the measuring tool to adjust to the ambient temper-
ature before putting it into operation. In case of extreme
temperatures or variations in temperature, the accuracy of the
measuring tool can be impaired.
Position the measuring tool at least 50 cm away from the rotational
laser level. Position the measuring tool in such a manner that the
laser beam can reach the reception area 6. Set the highest rotation-
al speed on the rotational laser level.

Switching On and Off
fA loud audio signal sounds when switching on the measuring
tool. “The A-weighted sound pressure level of the audio signal
at a distance of one meter is 95 dB(A).”
fDo not hold the measuring tool close to your ear! The loud au-
dio signal can cause hearing defects.
To switch on the measuring tool, press the On/Off button 1. Two
audio signals sound and all display indicators light up briefly.
To switch off the measuring tool, press the On/Off button 1again.
When no button is pressed on the measuring tool for approx.
10 minutes and when no laser beam reaches the reception area 6
for 10 minutes, the measuring tool automatically switches off in or-
der to save the battery. The switching off is indicated by an audio
signal.
Selecting the Setting of the Centre Indicator
With button 2, you can specify with which accuracy the position of
the laser beam is indicated as central on the reception area:
– “Fine” adjustment, (indication gon the display),
– “Medium” adjustment, (indication bon the display).
An audio signal sounds when the accuracy setting is changed.
Whenever switching on the measuring tool, the accuracy level “me-
dium” is set.

Direction Indicators
The bottom a, centre fand top dindicators (both on the front and
rear side of the measuring tool) indicate the position of the rotat-
ing laser beam in the reception area 6. Additionally, the position
can be indicated with an audio signal (see “Audio Signal for Indica-
tion of the Laser Beam”, page 27).
Measuring tool too low: When the laser beam runs through the top
half of the reception area 6, the bottom direction indicator aap-
pears on the display.
When the audio signal is switched on, a slow-beat signal sounds.
Move the measuring tool upward in the direction of the arrow.
When approaching the centre mark 5, only the tip of the direction
indicator ais indicated.
Measuring tool too high: When the laser beam runs through the
bottom half of the reception area 6, the top direction indicator d
appears on the display.
When the audio signal is switched on, a fast-beat signal sounds.
Move the measuring tool downward in the direction of the arrow.
When approaching the centre mark 5, only the tip of the direction
indicator dis indicated.
Measuring tool in centre position: When the laser beam runs
through the reception area 6at the centre mark 5, the centre indi-
cator flights up. When the audio signal is switched on, a continu-
ous signal sounds.

Bosch Power Tools 2 610 A12 917 | (19.1.10)
Audio Signal for Indication of the Laser Beam
The position of the laser beam on the reception area 6can be indi-
cated via an audio signal.
After the measuring tool has been switched on, the audio signal is
always switched off.
When switching on the audio signal, you can choose between two
volume levels.
To switch on the audio signal or change the volume level, push the
acoustic signal button 3until the requested volume level is indicat-
ed. At medium volume level, the audio signal indicator ein the dis-
play flashes; at high volume level, the indicator is continuously lit.
When the audio signal is set to off, the indicator goes out.
Working Advice
Marking
When the laser beam runs through the center of the reception area
6, its height can be marked at the centre mark 5right and left on
the measuring tool. The centre mark is located 45 mm away from
the top edge of the measuring tool.
Aligning with the Spirit Level
The measuring tool can be aligned vertically (plumb line) with the
spirit level 8. A measuring tool applied out-of-level leads to faulty
measurements.

Attaching with the Holder (see figure A)
With the holder 17, the measuring tool can be fastened to a con-
struction laser measuring rod 15 (accessory) as well as to other
auxiliary tools with a width of up to 65 mm.
Screw the holder 17 to the retainer opening 12 on the rear side of
the measuring tool with fastening screw 16.
Loosen the locking screw 13, slide the holder onto the construc-
tion laser measuring rod 15, for example, and retighten the locking
screw 13.
The upper edge 14 of the holder is located at the same height as
the centre mark 5and can be used for marking of 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 us-
ing the magnet plate 4.
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 clean-
ing agents or solvents.
If the measuring tool should fail despite the care taken in manufac-
turing 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 in-
clude the 10-digit article number given on the type plate of the
measuring tool.
