A) For measurements from the front edge of the measuring tool,
this applies for high reflectivity of the target (e.g. a white-
painted wall), weak backlighting and 25 °C operating temperat-
ure. In addition, a deviation of ±0.05 mm/m must be taken into
account.
B) For measurements from the front edge of the measuring tool,
this applies for high reflectivity of the target (e.g. a white-
painted wall), and strong backlighting. In addition, a deviation
of ±0.15 mm/m must be taken into account.
C) After calibration at 0° and 90°. Additional pitch error of max.
±0.01°/degrees up to 45°. The measurement accuracy refers to
the three orientations of the inclination measurement calibra-
tion, see figure H
D) At an operating temperature of 25 °C. Charging time with 1 A
USB charger. Faster charging with the measuring tool switched
off.
E) The left-hand side of the measuring tool serves as the reference
level for grade measurement.
F) In continuous measurement mode, the max. operating temper-
ature is +40 °C.
G) non-conductive soiling only, whereby occasional temporary
conductivity caused by condensation is expected
H) The automatic switch-off time can be adjusted (to two, five, ten
minutes or never).
I) When using Bluetooth® Low Energy devices, it may not be pos-
sible to establish a connection depending on the model and op-
erating system. Bluetooth® tools must support the GATT profile.
A long battery runtime is achieved by means of energy-saving meas-
ures, such as deactivating the Bluetooth® function when not required,
reducing the display brightness, etc.
The serial number (15) on the type plate is used to clearly identify
your measuring tool.

Initial start-up

Charging the battery

Use only the chargers listed in the technical data. Only
u
these chargers are matched to the lithium-ion battery of
your measuring tool.
The use of chargers from other manufacturers can
u
lead to defects on the measuring tool; a higher voltage
(e.g. 12 V) from a vehicle charger is not suitable for
charging this measuring tool. The warranty is
rendered void if these instructions are not followed.
Bosch Power Tools
Pay attention to the mains voltage. The voltage of the
u
power source must match the voltage specified on the
USB 2.0
rating plate of the charger.
5.0 V
Note: The battery is supplied partially charged. To ensure
1000 mA
full capacity of the battery, completely charge the battery
before the first use.
Li-ion
Note: The micro USB port (16) for connecting the micro
3.6 V
USB cable (22) is located under the cover of the measuring
3120 mAh
pin (8). Press the release button (7) to open the cover.

The lithium-ion battery can be charged at any time without
reducing its service life. Interrupting the charging process
does not damage the battery.

5.0 V
Charge the battery.
1000 mA
If the frame around the segments of the battery charge indic-
ator (g) flashes, no more measurements are possible. The
/ II
measuring tool can only be used for a short time (e.g. to
check entries in the measured value list). Charge the bat-
tery.
Connect the measuring tool to the charger (23) using the mi-
cro USB cable (22) provided. Plug the charger (23) into the
socket. The charging process will begin.
The battery charge indicator (g) indicates the charging pro-
gress. The segments flash successively during charging.
When all segments of the battery charge indicator (g) are
displayed, the battery is fully charged.
If you are not planning to use the power tool again soon, dis-
connect the charger from the mains.
The battery can also be charged at a USB port. To do so, con-
nect the measuring tool to a USB port using the micro USB
cable. In USB mode (charging mode, data transfer), the
charging time can be noticeably longer.
The measuring tool cannot be used on its own during the
charging process.
Bluetooth® switches itself off during the charging process.
Existing connections to other devices are interrupted. Data
can be lost in the process.
Recommendations for optimal handling of the battery in
the measuring tool
Only charge the measuring tool in the permissible temperat-
ure range, (see "Technical data", page 24). As an example,
do not leave the measuring tool in a vehicle during the sum-
mer.
A significantly reduced operating time after charging indic-
ates that the battery has deteriorated and must be replaced
by the Bosch after-sales service.
Follow the instructions on correct disposal.
Operation
Start-Up
Never leave the measuring tool unattended when
u
switched on, and ensure the measuring tool is
switched off after use. Others may be dazzled by the
laser beam.
