Operation with Non-Rechargeable Batteries
It is recommended that you use alkaline manganese batter-
ies to operate the measuring tool.
The batteries are inserted into the battery adapter.
The battery adapter is intended only for use in desig-

nated Bosch measuring tools and must not be used
with power tools.

inside the battery bay, reach into the cover and pull it out of
the measuring tool, applying light pressure to the side wall as
you do so.
Always replace all the batteries at the same time. Only use
batteries from the same manufacturer and which have the

has been subjected to significant fluctuations in temper-
ature, first allow the measuring tool to adjust to the ambi-
ent temperature and then always carry out an accuracy
check before continuing work (see "Accuracy Check of
the Measuring Tool", page 22).
The precision of the measuring tool may be compromised
if exposed to extreme temperatures or fluctuations in
temperature.
Avoid substantial knocks to the measuring tool and

avoid dropping it.
Always carry out an accuracy check
before continuing work if the measuring tool has been
subjected to severe external influences (see "Accuracy
Check of the Measuring Tool", page 22).
Switch the measuring tool off when transporting it.

The pendulum unit is locked when the tool is switched off,
as it can otherwise be damaged by big movements.
Switching On/ Off
switch on
To the measuring tool, slide the on/ off
( 16) On
switch to the " " position (for working with the pen-
On
dulum lock) or to the " " position (for working with
automatic levelling). As soon as it is switched on, the meas-
uring tool emits laser lines from the outlet apertures
Do not direct the laser beam at persons or animals and

do not stare into the laser beam yourself (even from a
distance) .
switch off
To the measuring tool, slide the on/ off switch
( 16) Off
to the position. The pendulum unit is locked when
the tool is switched off.
Never leave the measuring tool unattended when

switched on, and ensure the measuring tool is
switched off after use.
Others may be blinded by the
laser beam.
If the maximum permitted operating temperature of
exceeded, the tool shuts down to protect the laser diode.
Once it has cooled down, the measuring tool is operational
again and can be switched back on.
If the temperature of the measuring tool is approaching the
maximum permissible operating temperature, the laser lines
will gradually become dimmer.
Deactivating the Automatic Shut-Off Function
If no button on the measuring tool is pressed for approx.
120 min, the measuring tool will automatically switch itself
off to preserve battery life.
To switch the measuring tool back on after it has been auto-
matically switched off, you can either slide the on/ off switch
( 16) Off
to the " " position first and then switch the measur-
ing tool back on, or press either the laser mode button
( 5)
the receiver mode button once.
To deactivate the automatic shut-off function, hold down the
( 7)
laser mode button for at least 3 s (with the measuring
tool switched on). If the automatic shut-off function is deac-
tivated, the laser beams will flash briefly as confirmation.
To activate the automatic shut-off function, switch the meas-
uring tool off and on again.
