Degree of protection (excluding

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 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 ±10 mm per 40 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 measuring tool can be clearly identified with the serial number 17
on the type plate.
Assembly
Inserting/Replacing the Batteries (see figure A)
Use only alkali-manganese or rechargeable batteries.
Less measurements are possible when using 1.2 V recharge-
able batteries than with 1.5 V batteries.
To open the battery lid 16, press the latch 15 in the direction
of the arrow and remove the battery lid. Insert the batteries
provided. Pay attention to the correct polarity of the batteries
according to the representation in the battery compartment.
When the battery symbol appears in the display for the
first time, then at least 100 measurements are still possible.
The batteries must be replaced when the battery symbol
flashes; taking measurements is no longer possible.
Always replace all batteries at the same time. Only use batter-
ies from one brand and with the identical capacity.
 Remove the batteries from the measuring tool when
not using it for extended periods. When storing for ex-
tended periods, the batteries can corrode and self-dis-
charge.
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.
Bosch Power Tools
 Do not subject the measuring tool to extreme tempera-
DLE 40 Professional
tures or variations in temperature. As an example, do
not leave it in vehicles for longer periods. In case of large
20 s
variations in temperature, allow the measuring tool to ad-
just to the ambient temperature before putting it into oper-
5 min
ation.
 Avoid heavy impact to or falling down of the measuring
0.18 kg
tool. After severe exterior effects to the measuring tool, it
58 x 100 x 32 mm
is recommended to carry out an accuracy check (see "Ac-
IP 54 (dust and splash
curacy Check of the Measuring Tool", page 16) each time
water protected)
before continuing to work.
Switching On and Off
 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.
To switch on the measuring tool, briefly press the On/Off but-
ton 13 or measuring button 9. When switching on the measur-
ing tool, the laser beam is not switched on yet.
To switch off the measuring tool, press the On/Off button 13
for 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 auto-
matic switch-off mode. When switching on the measuring tool
again, "M" is indicated in the display.
Measuring Procedure
After switching on, the measuring tool is in the length meas-
urement mode. Other measuring modes can be switched to
by pressing the respective function/mode button (see "Meas-
uring Functions", page 14).
After switching on, the rear edge of the measuring tool is pre-
set as the reference level for the measurement. To change the
reference level, see "Selecting the Reference Level
(see figure B–C)", page 14.
Upon selection of the measuring function and the reference
level, all further steps are carried out by pushing the measur-
ing button 9.
With the reference level selected, place the measuring tool
against the desired measuring line (e.g. a wall).
Briefly press the measuring button 9 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 9 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 and latest af-
ter 4 seconds. The duration of the measurement depends on
the distance, the light conditions and the reflection proper-
ties of the target surface. The end of the measurement is indi-
cated by a signal tone. The laser beam is switched off auto-
matically upon completion of the measurement.
