Assembly

Inserting/Replacing the Battery

Alkali-manganese batteries are recommended
for the measuring tool.
To open the battery lid 12, slide the latch 11 in
the direction of the arrow and fold the battery
lid up. Insert the batteries. When inserting, pay
attention to the correct polarity according to the
representation on the inside of the battery lid.
When the batteries become weak, a single 5 s
audio signal will sound. The battery low indica-
tor 2 continuously flashes red. The measuring
tool can be operated for less then 2 h.
Bosch Power Tools
When the batteries are weak when switching on
the measuring tool, the 5 s audio signal will
sound directly after switching on the measuring
tool.
Always replace all batteries at the same time.
Only use batteries 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 extended periods, the bat-
teries can corrode and discharge them-
selves.
Operation

Initial Operation

Loud audio signals will sound under certain
conditions while operating the measuring
tool. Therefore, keep the measuring tool
away from your ear or other persons. The
loud audio signal can cause hearing damage.
Protect the measuring tool against mois-
ture and direct sun light.
Do not subject the measuring tool to ex-
treme temperatures or variations in tem-
perature. As an example, do not leave it in
vehicles for longer periods. In case of large
variations in temperature, allow the measur-
ing tool to adjust to the ambient temperature
before putting it into operation. In case of ex-
treme temperatures or variations in tempera-
ture, the accuracy of the measuring tool can
be impaired.
Avoid heavy impact or falling of the measur-
ing tool. After heavy exterior impact on the
measuring tool, an accuracy check should al-
ways be carried out before continuing to
work (see "Levelling Accuracy").
Switch the measuring tool off during trans-
port. When switching off, the levelling unit,
which can be damaged in case of intense
movement, is locked.
