Assembly
Inserting/Replacing the Battery
Usingalkali-manganeseorrechargeablebatteriesis recommended foroperation
of the measuring tool.
Less measurements are possible when using 1.2 V rechargeable batteries than
with 1.5 V batteries.
To open the battery lid 15, press the latch 14 in the direction of the arrow and
remove the battery lid. Insert the batteries/rechargeable batteries. When insert-
ing, pay attention 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 measurements are still possible. When the battery symbol flashes, the bat-
teries/rechargeable 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 batteries/rechargeable batteries together.
fRemove the batteries/rechargeable batteries from the measuring tool
when not using it for longer periods. When storing for longer periods, the
batteries/rechargeable batteries can corrode and discharge themselves.
Operation
Initial Operation
fDo not leave the switched on measuring tool unattended and switch the
measuring tool off after use.Other persons could be blinded by the laser
beam.
fProtect the measuring tool against moisture and direct sun light.
fDonotsubjectthe measuring tool to extreme temperatures orvariations
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 adjust
to the ambient temperature before putting it into operation. In case of ex-
tremetemperaturesor variations in temperature, the accuracy of the measur-
ing tool can be impaired.

Dimensions 58 x 104 x 36 mm
Degree of protection (excluding battery com-
partment) IP 44 (splash water protected)
A) The working range increases depending on how well the laser light is reflected from the sur-
face of the target (scattered, not reflective) and with increased brightness of the laser point to
the ambient light intensity (interior spaces, twilight). In unfavourable conditions (e.g. when
measuring outdoors at intense sunlight), it may be necessary to use the target plate.
B) In unfavourable conditions (e.g. at intense sunlight or an insufficiently reflecting surface),
the maximum deviation is ±7 mm per 25 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.
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 18 on the type plate.

fAvoid 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 accu-
racy check (see “Accuracy Check of the Measuring Tool”, page 22) each time
before continuing to work.
Switching On and Off
To switch on the measuring tool, briefly press the On/Off button 1or measuring
button 9. When switching on the measuring tool, the laser beam is not switched
on yet.
To switch off the measuring tool, press the On/Off button 1for a few seconds.
If none of the measuring tool buttons are pressed for approx. 5 minutes, the
measuring tool switches off automatically in order to extend the service life of
the battery.
When a measured value has been stored, it is retained in automatic switch-off
mode. When switching on the measuring tool again, “M” is indicated in the dis-
play.
Measuring Procedure
Afterswitchingon, themeasuringtool isinthelength measurementmode.Other
measuring modes can be switched to by pressing the respective function/mode
button (see “Measuring Functions”, page 18).
After switching on, the rear edge of the measuring tool is preset as the reference
level for the measurement. To change the reference level, see “Selecting the Ref-
erence Level”, page 18.
Upon selection of the measuring function and the reference level, all further
steps are carried out by pushing the measuring button 9.
With the reference level selected, place the measuring tool against the desired
measuring line (e.g. a wall).
Push the measuring button 9to switch on the laser beam.
fDonotpointthelaserbeam at persons oranimalsanddonot look into the
laser beam yourself, not even from a large distance.
Aim the laser beam at the target surface. Push the measuring button 9again to
initiate the measurement.
In the tracking function, the measurement already starts upon first actuation of
the measuring button 9.
Typically, the measured value appears after 0.5 and latest after 4 seconds. The
duration of the measurement depends on the distance, the light conditions and
the reflection properties of the target surface. The end of the measurement is in-
dicated by a signal tone. The laser beam is switched off automatically upon com-
pletion 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 figures A–B)
Two different reference levels are available for measuring:
– The rear edge of the measuring tool (e.g. when placing against a wall),
– The front measuring-tool edge (e.g. when measuring onward from a table
edge).
To change the reference level, press button 2until the requested reference level
is indicated on the display. Each time after switching on the measuring tool, the
rear end of the measuring tool is preset as the reference level.
Measuring Functions

display.
Area Measurement
For area measurements, push button 5. The indicator for area measurement ap-
pears in the display .
Afterwards, measure the length and the width, one after another, in the same
manner as a length measurement. The laser beam remains switched on between
both measurements.
After taking the second measurement, the area/sur-
face is automatically calculated and displayed. The
last individual measured value is indicated at the bot-
tom in the display, while the final result is shown at
the top.
Volume Measurement
For volume measurements, push button 10. The indicator for volume measure-
ment appears in the display .
Afterwards, measure the length, width and the height, one after another, in the
same manner as for a length measurement. The laser beam remains switched on
between all three measurements.
After taking the third measurement, the volume is au-
tomatically calculated and displayed. The last individ-
ual measured value is indicated at the bottom in the
display, while the final result is shown at the top.
Continuous Measurement (Tracking) (see figure C)
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 example, you can move a certain distance away from a wall,
while the actual distance can always be read.
For continuous measurements, push button 12. The indicator for continuous
measurement (tracking) appears in the display .
Press the measuring button 9to initiate the measur-
ing procedure. Move the measuring tool until the re-
quireddistancevalueis indicatedatthe bottomofthe
display.
Pushingthemeasuringbutton9interrupts the contin-
uous measurement. The current measured value is in-
dicated in the display. Repeated pushing of the measuring button 9starts the
continuous measuring again.
The continuous measurement automatically switches off after 5 minutes. The
lastmeasuredvalue remains indicated on thedisplay.The continuousmeasuring
can also be ended by pushing the buttons 6, 5or 10 which changes the measur-
ing function.

Deleting Measured Values
Briefly pressing button 1deletes the last individual measuring value determined
in all measuring functions. Briefly pressing the button repeatedly deletes the in-
dividual measured values in reverse order.
Memory Functions
When switching off the measuring tool, the value in the memory is retained.
Storing/Adding Measured Values
Push the memory add button 4in order to store the
current measured value – a length, area or volume
value, depending on the current measuring function.
As soon as a value has been stored, “M” is indicated
in the display and the “+” behind it briefly flashes.
If a value is already stored in the memory, the new val-
ue is added tothe memory contents, however, only
when the measures of unit correspond.
As an example, when an area value is in the memory and the current measured
value is a volume value, the addition cannot take place. “Error” briefly flashes in
the display.
Subtracting Measured Values
Pushthememorysubtractionbutton 3in ordertosubtractthe current measured
value from the memory value. As soon as a value has been subtracted, “M” is in-
dicated in the display and the “–” behind it briefly flashes.
If a value is already stored in the memory, the new measured value can be sub-
tracted only when the measures of unit correspond (see “Storing/Adding Meas-
ured Values”).
Displaying the Stored Value
Push the memory retrieve button 11 in order to dis-
play the value stored in the memory. “M=” is indicat-
edinthe display.Whenthe memorycontents“M=”is
indicated in the display, it can be doubled by pushing
the memory add button 4or set to zero by pushing
the memory subtract button 3.
Deleting the Memory
To delete the memory contents, first push the memory retrieve button 11, so
that “M=” is indicated in the display. Then briefly press button 1; “M” is no long-
er indicated in the display.
Working Advice
General Information
The reception lens 17 and the laser beam outlet 16 must not be covered when
taking a measurement.
The measuring tool must not be moved while taking a measurement (with the ex-
ception of the continuous measurement function). Therefore, place the measur-
ing tool, as far as this is possible, against or on the measuring points.
Measurement takes place at the centre of the laser beam, even when target sur-
faces are sighted at an incline.
Influence Effects on the Measuring Range
The measuring range depends upon the light conditions and the reflection prop-
erties of the target surface. For improved visibility of the laser beam when work-
ing outdoors and when the sunlight is intense, use the laser viewing glasses 19
(accessory) and the laser target plate 20 (accessory),orshadeoff thetargetsur-
face.

Bosch Power Tools 2 609 140 620 | (14.7.11)
Influence Effects on the Measuring Result
Due to physical effects, faulty measurements cannot be excluded when measur-
ing 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),
– Structured surfaces (e.g., roughcast, natural stone).
If required, use the laser target plate 20 (accessory) on these surfaces.
Also, air layers with varying temperatures or indirectly received reflections can
affect the measured value.
Sighting with the Alingment Aid (see figure D)
With the alignment aid 8, sighting over larger distances is a lot easier. For this,
look alongside the aligning aid on the top side of the measuring tool. The laser
beam runs parallel to this line of sight.
Troubleshooting –Causes and Corrective Measures

The measuring tool monitors the correct function for each
measurement. When a defect is determined, only the symbol
shown aside flashes in the display. In this case, or when the
above mentioned corrective measures cannot correct an er-
ror, have the measuring tool checked by an after-sales service
agent for Bosch power tools.
Accuracy Check of the Measuring Tool
The accuracy of the measuring tool can be checked as follows:
– Select a permanently unchangeable measuring section with a length of ap-
prox. 3 to 10 metres; its length must be precisely known (e.g. the width of a
room or a door opening). 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 ex-
ceed ±3 mm (max.). Log the measurements, so that you can compare their ac-
curacy at a later point of time.
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 17 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 manufacturing and test-
ing procedures, repair shouldbe carried out by an authorised after-sales service
centre for Bosch power tools. Do not open the measuring tool yourself.
