Assembly
Inserting/Replacing the Battery
Using alkali-manganese or rechargeable batteries is recom-
mended for operation of the measuring tool.
Less measurements are possible when using 1.2 V recharge-
able batteries than with 1.5 V batteries.
To open the battery lid 10, press the latch 16 and remove the
battery lid. Insert the batteries/rechargeable batteries. When
inserting, pay attention to the correct polarity according to
the representation on the inside of the battery compartment.
When inserting the batteries/rechargeable batteries, pay at-
tention to the correct polarity according to the representation
on the inside of the battery compartment.
When the battery symbol appears for the first time on the
display, at least 100 individual measurements are still possi-
ble. The continuous measurement mode is deactivated.
When the battery symbol flashes, the batteries/recharge-
able batteries must be replaced. Measurements are no longer
possible.
Always replace all batteries/rechargeable batteries at the
same time. Do not use different brands or types of batter-
ies/rechargeable batteries together.
Remove the batteries/rechargeable batteries from the
measuring tool when not using it for longer periods.
When storing for longer periods, the batteries/rechargea-
ble batteries can corrode and discharge themselves.
Operation
Initial Operation
Do not leave the switched on measuring tool unattend-
ed and switch the measuring tool off after use. Other
persons could be blinded by the laser beam.
Protect the measuring tool against moisture and direct
sun light.
Do not subject the measuring tool to extreme tempera-
tures 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 measuring tool to ad-
just to the ambient temperature before putting it into oper-
A) The working range increases depending on how well the laser light is reflected from the surface of the target (scattered, not reflective) and with in-
creased brightness of the laser point to the ambient light intensity (interior spaces, twilight). In unfavourable conditions (e.g. when measuring out-
doors at intense sunlight), it may be necessary to use the target plate.
B) For measurements from the rear measuring-tool edge. In unfavourable conditions (e. g. at intense sunlight or an insufficiently reflecting surface),
the maximum deviation is
±
10 mm per 50 m. In favourable conditions, a deviation influence of ± 0.05 mm/m must be taken into account.
C) In the continuous measurement function, the maximum operating temperature is +40 °C.
D) Less measurements are possible when using 1.2 V rechargeable batteries than with 1.5 V batteries. The battery life listed refers to measurements
without display illumination.
Please observe the article number on the type plate of your measuring tool. The trade names of the individual measuring tools may vary.
The measuring tool can be clearly identified with the serial number 13 on the type plate.

ation. In case of extreme temperatures or variations in
temperature, the accuracy of the measuring tool can be im-
paired.
Avoid heavy impact to or falling down of the measuring
tool. After severe exterior effects to the measuring tool, it
is recommended to carry out an accuracy check (see “Ac-
curacy Check of the Distance Measurement”, page 16)
each time before continuing to work.
Switching On and Off
For switching on the measuring tool, the following possibili-
ties are given:
– Pressing the On/Off button 4: The measuring tool is
switched on and is in length measurement mode. The laser
is not activated.
– Pressing the measuring button 2: Measuring tool and laser
are switched on. The measuring tool is in length measure-
ment mode.
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 measuring tool, press the On/Off button 4
for a few seconds.
When no button on the measuring tool is pressed for approx.
5 minutes, the measuring tool automatically switches off to
save the batteries.
Measuring Procedure
After switching on by pressing the measuring button 2, the
measuring tool is always in length measurement mode. Other
measuring modes can be switched to by pressing the respec-
tive function/mode button (see “Measuring Functions”,
page 14).
After switching on, the rear edge of the measuring tool is pre-
set as the reference level for the measurement. By pressing
the reference level button 6, the reference level can be
changed (see “Selecting the Reference Level”, page 14).
Place the measuring tool with the selected reference plane
against the desired starting point of the measurement (e.g. a
wall).
Briefly press the measuring button 2 to switch on the laser
beam.
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.
Aim the laser beam at the target surface. Briefly press the
measuring button 2 again to initate the measurement.
In the continuous measurement mode, the measurement be-
gins immediately upon switching on the function.
Typically, the measured value appears after 0.5 seconds and
latest after 4 seconds. The duration of the measurement de-
pends on the distance, the light conditions and the reflection
properties of the target surface. The laser beam is switched
off automatically upon completion of the measurement.
When no measurement has taken place approx. 20 seconds
after sighting, the laser beam is switched off automatically to
save the batteries.
Selecting the Reference Level (see figure A)
For the measurement, you can select between three different
reference planes:
– The rear measuring-tool edge (e.g. when measuring on-
ward from a wall),
– The front measuring-tool edge (e.g. when measuring on-
ward from a table edge),
– The centre of thread 14 (e.g. for tripod measurements).
To select the reference level, press button 6 until the request-
ed reference level is indicated on the display. Each time after
switching on the measuring tool, the rear end of the measur-
ing tool is preset as the reference level.
Display Illumination
The display illumination is automatically activated, depending
on the ambient brightness. When no button is pressed after
the display illumination switches on, it is dimmed to save the
batteries.
Measuring Functions
Simple Length Measurement (see figure B)
For length measurements, press button 9 until the “length
measurement” indication appears on the display.
To switch the laser on and for measuring,
briefly press the measuring button 2 once
each time.
The measured value is displayed in the re-
sult line b.
For several subsequent length measurements, the last meas-
ured results are displayed in the measured-value lines a.
Area Measurement (see figure C)
For area/surface measurements, press button 3 until the indi-
cator for area/surface measurement appears on the dis-
play.
Afterwards, measure the length and the width, one after an-
other, in the same manner as a length measurement. The laser
beam remains switched on between both measurements.
Upon completion of the second measure-
ment, the surface is automatically calcu-
lated and displayed in the result line b.
The individual measured values are dis-
played in the measured-value lines a.
Volume Measurement (see figure D)
For volume measurements, press button 3 until the indicator
for volume measurement appears on the display.
Afterwards, measure the length, width
and the height, one after another, in the
same manner as for a length measure-
ment. The laser beam remains switched
on between all three measurements.
Upon completion of the third measure-
ment, the volume is automatically calcu-
lated and displayed in the result line b.
The individual measured values are dis-
played in the measured-value lines a.

cannot be indicated; “ERROR” ap-
pears on the display. Divide the volume to be measured into
individual measurements; their values can then be calculated
separately and then summarized.
Continuous Measurement (Tracking) (see figure E)
For continuous measurements, the measuring tool can be
moved relative to the target, whereby the measuring value is
updated approx. every 0.5 seconds. In this manner, as an ex-
ample, you can move a certain distance away from a wall,
while the actual distance can always be read.
For continuous measurements, press button 9 until the indi-
cator for continuous measurement appears on the display.
To start the continuous measurement, press the measuring
button 2.
The current measured value is displayed
in the result line b.
Pressing the measuring button 2 ends the
continuous measurement. The last meas-
ured value is displayed in the result line b.
Pressing the measuring button 2 again re-
starts a continuous measuring run.
Continuous measurement automatically switches off after
5 min. The last measured value remains indicated in the result
line b.
Indirect height measurement / Simple Pythagoras Meas-
urement (see figure F)
The indirect height measurement is used to measure distanc-
es that cannot be measured directly because an obstacle
would obstruct the laser beam or no target surface is available
as a reflector. Correct results are achieved only when the right
angles required for the respective measurement are exactly
adhered to (Pythagorean Theorem).
Pay attention that the reference plane of the measurement
(e.g. the rear edge of the measuring tool) remains exactly at
the same location for all individual measurements within a
measuring sequence.
The laser beam remains switched on between the individual
measurements.
Press button 3 until the indication for simple Pythagoras
measurement appears on the display.
Measure distances “1” and “2” in this sequence as for a
length measurement. Pay attention that a right angle exists
between distance “1” and the sought distance “X”.
Upon completion of the last measure-
ment, the result for the sought distance
“X” is displayed in the result line b. The in-
dividual measured values are displayed in
the measured-value lines a.
Deleting Measured Values
Briefly pressing button 4 deletes the last individual measuring
value determined in all measuring functions. Briefly pressing
the button repeatedly deletes the individual measured values
in reverse order.
Adding Measured Values
To add measuring values, firstly carry out a measurement.
Then press the plus button 8. For confirmation, “+” appears
on the display.
To add volumes or areas/surfaces, press the plus button 8 af-
ter the first completed measuring process. For confirmation,
“+” appears on the display left of the volume/area symbol.
Then carry out a second measurement.
To call up the sum of both measurements,
press the plus button 8 again. The calcula-
tion is indicated in the measured-value
lines a, and the sum in the result line b.
After calculation of the sum, further
measured values can be added to this re-
sult when pressing the plus button 8 prior to each measure-
ment.
Notes on the addition:
– Mixed length, area/surface and volume values cannot be
added together. For example, when a length and area val-
ue are added, “ERROR” briefly appears on the display af-
ter pressing the plus button 8. Afterwards, the measuring
tool switches back to the last active measuring mode.
– For each calculation, the result of one measurement is
added (e.g. the volume value); for continuous measure-
ments, this would be the displayed measured value in re-
sult line b. The addition of individual measured values from
the measured-value lines a is not possible.
Subtracting Measured Values
To subtract measuring values, press mi-
nus button 5; For confirmation, “–” is in-
dicated on the display. The further proce-
dure is analog to “Adding Measured
Values”.
Working Advice
General Information
The reception lens 12 and the laser beam outlet 11 must not
be covered when taking a measurement.
The measuring tool must not be moved while taking a meas-
urement (with the exception of the continuous measurement
function). Therefore, place the measuring tool, as far as this is
possible, against or on a firm stop or supporting surface.
Influence Effects on the Measuring Range
The measuring range depends upon the light conditions and
the reflection properties of the target surface. For improved
visibility of the laser beam when working outdoors and when
the sunlight is intense, use the laser viewing glasses 19 (ac-
cessory) and the laser target plate 20 (accessory), or shade
off the target surface.
Influence Effects on the Measuring Result
Due to physical effects, faulty measurements cannot be ex-
cluded when measuring on different surfaces. Included here
are:
– Transparent surfaces (e.g., glass, water),
– Reflecting surfaces (e.g., polished metal, glass),
– Porous surfaces (e.g. insulation materials),

16 | English
2 609 140 773 | (19.10.11) Bosch Power Tools
– Structured surfaces (e.g., roughcast, natural stone).
If required, use the laser target plate 20 (accessory) on these
surfaces.
Furthermore, faulty measurements are also possible when
sighting inclined target surfaces.
Also, air layers with varying temperatures or indirectly re-
ceived reflections can affect the measured value.
Accuracy Check of the Distance Measurement
The accuracy of the distance measurement can be checked as
follows:
– Select a permanently unchangeable measuring section
with a length of approx. 1 to 10 metres; its length must be
precisely known (e.g. the width of a room or a door open-
ing). The measuring distance must be indoors; the target
surface for the measurement must be smooth and reflect
well.
– Measure the distance 10 times after another.
The deviation of the individual measurements from the mean
value must not exceed ± 2 mm (max.). Log the measure-
ments, so that you can compare their accuracy at a later point
of time.
Working with the Tripod (Accessory)
The use of a tripod is particularly necessary for larger distanc-
es. Position the measuring tool with the 1/4" thread 14 onto
the quick-change plate of the tripod 18 or a commercially
available camera tripod. Tighten the measuring tool with the
locking screw of the quick-change plate.
Set the corresponding reference level for measurement with
a tripod by pushing button 6 (the reference level is the
thread).
Troubleshooting
–
Causes and Corrective Meas-
ures
The measuring tool monitors the correct
function for each measurement. When a de-
fect is determined, only the symbol shown
aside flashes in the display. In this case, or
when the above mentioned corrective
measures cannot correct an error, have the
measuring tool checked by an after-sales service agent for
Bosch power tools.
Maintenance and Service
Maintenance and Cleaning
Store and transport the measuring tool only in the supplied
protective pouch.
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 solvents.
Maintain the reception lens 12 in particular, with the same
care as required for eye glasses or the lens of a camera.
If the measuring tool should fail despite the care taken in man-
ufacturing and testing procedures, repair should be carried
out by an authorised after-sales service centre for Bosch pow-
er 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.
In case of repairs, send in the measuring tool packed in its
protective pouch 17.

The angle between the laser beam
and the target is too acute.
Enlarge the angle be-
tween the laser beam
and the target
The target surface reflects too in-
tensely (e.g. a mirror) or insuffi-
ciently (e.g. black fabric), or the
ambient light is too bright.
