your measuring tool.
Assembly
Measuring Tool Power Supply
The measuring tool can be operated either with commer-
cially available batteries or with a commercially available
power supply with an output voltage of 6 V (direct current).
If batteries are inserted while a power supply is also connec-
ted, the measuring tool is supplied with power by the power
supply.
Operation with Non-Rechargeable Batteries
It is recommended that you use alkaline manganese batter-
ies to operate the measuring tool.
Turn the locking mechanism
(13)
(e.g. using a coin) to open
the battery compartment cover
(14)
. Remove the battery
compartment cover. Insert the batteries.
When inserting the batteries, ensure that the polarity is cor-
rect according to the illustration on the inside of the battery
compartment.
If the batteries become weak, the status indicator
(20)
will
flash. It is still possible to work with the measuring tool.
Once the batteries are drained, the measuring tool will no
longer react if a button is pressed. The status indicator
(20)
will flash for another 40 s, then the measuring tool will auto-
matically switch itself off.
Always replace all the batteries at the same time. Only use
batteries from the same manufacturer and which have the
same capacity.
u
Take the batteries out of the measuring tool when you
are not using it for a prolonged period of time.
The bat-
teries can corrode and self-discharge during prolonged
storage in the measuring tool.
Operation with power supply
Open the cover
(12)
of the 6 V charging socket
(11)
. Plug
the charging connector of a commercially available 6 V
power supply into the charging socket
(11)
. Connect the
power supply to the mains supply.
After removing the charging connector, close the cover
(12)
again to protect against dirt.
Working with the rotating platform
Unscrew the legs of the rotating platform
(8)
with the height
adjustment screws
(17)
.
Roughly align the rotating platform using the spirit
level
(10)
.
You can use the fine adjustment screw
(9)
to align vertical
laser lines precisely with reference points.
Contact an authorised
Bosch
after-sales service centre if you
want to use the measuring tool without the rotating platform.
The precision of the measuring tool may be compromised if
the calibration is not adapted for operation without the rotat-
ing platform.
