Dimensions
Degree of protection
1) The working range can be decreased by unfavourable environmental conditions (e.g. direct sun irradiation).
2) The angular accuracy between the 45° laser line and the 90° laser line is max. ±0.4 mm/m.
The measuring tool can be clearly identified with the serial number 5 on the type plate.
Assembly

Inserting/Replacing the Batteries

Alkali-manganese batteries are recommended for the
measuring tool.
To open the battery lid 6, press on the latch 7 and fold the
battery lid up. Insert the batteries. When inserting, pay
attention to the correct polarity according to the repre-
sentation on the inside of the battery compartment.
When the battery indication 8 flashes, the batteries are
weak. When the battery indication flashes for the first time,
the measuring tool can still be operated for approx. 2 h.
When the battery indication 8 lights up constantly, meas-
uring is no longer possible. The measuring tool automati-
cally switches off after a short time.
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 stor-
ing for extended periods, the batteries can corrode
and self-discharge.
Operation

Initial Operation

 Protect the measuring tool against moisture and
direct sun light.
 Do not subject the measuring tool to extreme tem-
peratures or variations in temperature. As an exam-
ple, do not leave it in vehicles for a long time. In case of
large variations in temperature, allow the measuring
tool to adjust to the ambient temperature before put-
ting it into operation. In case of extreme temperatures
Bosch Power Tools
IP 54 (dust and splash water protected)
or variations in temperature, the accuracy of the meas-
uring tool can be impaired.
 Avoid hard knocks to the measuring tool or drop-
ping it. Damaging the measuring tool can cause accu-
racy to be compromised. Following a hard knock or
fall, carry out a check by comparing the laser lines or
plumb beams with a known horizontal or vertical refer-
ence line or verified perpendicular points.
Switching On and Off
To switch on the measuring tool, press the On/Off button
3 once briefly. Immediately after the switching on, the
measuring tool projects the three laser lines 0°, 45° and
90° from the exit openings 1. Furthermore, the battery
indication 8 lights up for 3 s.
 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.
When the On/Off button 3 is pressed a second time, the
measuring tool switches over from 3-line operation to
2-line operation: Only the 0° and the 90° laser lines are
projected.
To switch off the measuring tool, press the On/Off button
3 a third time.
Deactivating the Automatic Shut-off
The measuring tool switches off automatically after an
operating duration of 30 minutes.
To deactivate the automatic switch-off, press the On/Off
button 3 for 3 s when you switch on the measuring tool.
When the automatic switch-off is deactivated, the laser
lines flash briefly to confirm after the switching on.
 Do not leave the switched-on measuring tool unat-
tended and switch the measuring tool off after use.
Other persons could be blinded by the laser beam.
