Switching On and Off
To switch on the measuring tool, slide the On/Off switch 2 to
the "On" position. Immediately after switching on, the meas-
uring tool sends laser beams out of the exit openings 1.
 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.
To switch off the measuring tool, slide the On/Off switch 2 to
the "Off" position. When switching off, the levelling unit is
locked.
 Do not leave the switched-on measuring tool unattend-
ed and switch the measuring tool off after use. Other
persons could be blinded by the laser beam.

Operating Modes

After switching on, the measuring tool is in cross-line operat-
ing mode with automatic levelling.
To change the operating mode, press the "Mode" button 8
until the requested operating mode is indicated by the corre-
sponding illuminated operating-mode indication 10.
The following operating modes are available:
Indication Operating Mode
Cross-line operation (see figures A, B and E):
The measuring tool generates a horizontal
laser plane (360° rotating laser line) and a
vertical laser line.
Horizontal operation (see figure C): The
measuring tool generates a horizontal laser
plane.
Vertical operation (see figure D): The meas-
uring tool generates a vertical laser line.
All three operating modes can be selected either with or with-
out automatic levelling.

Automatic Levelling

Working with Automatic Levelling (see figure F–G)
When working with automatic levelling, the indicator for
working without automatic levelling 11 must not be lit. If re-
quired, switch the automatic levelling on again by pressing
the "Lock" button 7 so that the indicator 11 goes out.
Position the measuring tool on a level and firm support, attach
it to the holder 12 or to the tripod 17.
After switching on, the levelling function automatically com-
pensates irregularities within the self-levelling range of ±4°.
The levelling is finished as soon as the laser beams do not
move any more.
If the automatic levelling function is not possible, e.g. be-
cause the surface on which the measuring tool stands devi-
ates by more than 4° from the horizontal plane, the levelling
warning indicator 9 lights up red and the laser is automatically
switched off. In this case, bring the measuring tool to the level
position and wait for the self-levelling to take place. As soon
as the measuring tool is within the self-levelling range of ±4°,
the levelling warning indicator 9 goes out and the laser is
switched on.
Bosch Power Tools
When not within the self-levelling range of ±4°, working with
automatic levelling is not possible, because it cannot be as-
sured that the laser lines run at a right angle to each other.
In case of ground vibrations or position changes during oper-
ation, the measuring tool is automatically levelled in again.
To avoid errors, check the position of the horizontal and ver-
tical laser line with regard to the reference points upon re-
levelling.
Working without Automatic Levelling (see figure E)
When working without automatic levelling, press the "Lock"
button 7. When the automatic levelling is switched off, indica-
tor 11 lights up red.
When the automatic levelling is switched off, the measuring
tool can be held by hand or placed on an inclined surface. In
cross-line operation, the two laser lines do not necessarily run
at a right angle to each other.

Working Advice

 Always use the centre of the laser line for marking. The
width of the laser line changes with the distance.
Working with the Tripod
A tripod 17 offers a stable, height-adjustable measuring sup-
port. Place the measuring tool via the tripod mount 3 onto the
1/4" male thread of the tripod 17 or a commercially available
camera tripod and screw the locking screw of the tripod tight.
Adjust the tripod roughly before switching on the measuring
tool.
Fastening with the Universal Holder (Accessory)
(see figures H–K)
With the universal holder 12, you can fasten the measuring
tool, e.g., to vertical surfaces. The universal holder is also
suitable for use as a ground tripod and makes the height ad-
justment of the measuring tool easier.
Fold the holding plate 14 of the universal holder 12 upward
(a) as shown in the figure, so that it engages in this position.
Lower the holding plate with adjustment knob 13 to the de-
sired height (b).
When using as a wall mount, fasten the universal holder 12 as
vertical as possible to a wall with the holding plate folded up.
Secure it safely against slipping off, e.g., with a fastening
screw (commercially available).
To use the universal holder as a table tripod, fold out the base
plate 15 until parallel to the holding plate (c).
Screw the 1/4" screw 16 of the wall mount into the tripod
mount 3 of the measuring tool.
Adjust the universal holder roughly before 12 switching on
the measuring tool.
To fold the universal holder 12 together, push the base plate
15 back against the corpus of the holder. Raise the holding
plate 14 with adjustment knob 13 to the highest position.
Then push the holding plate downward against the corpus.
