 Position the measuring tool only on a clean levelling
plate 10. The measuring tool cannot stand level on an
uneven, soiled levelling plate surface, which could lead
to faulty measuring results.
Working with the levelling plate (see figures D–E)
Using the levelling plate 10 you can position the measur-
ing tool flat on an uneven or unstable floor.
The levelling plate 10 can also be used as a wall bracket
for the measuring tool. Fix the levelling plate (securing it
against slipping) on a wall or an inclined surface using e.g.
standard screws. Use a level to fix the levelling plate flat
on the surface.
Positioning of the measuring tool on the levelling
plate: Position the measuring tool with the magnets 4 on
the underside on the levelling plate 10. The line grid on
the upper side of the levelling plate facilitates the precise
positioning of the measuring tool. In order to mark 90° or
45° angles, position the levelling plate at a reference edge
or a projection on a wall and position the measuring tool
as illustrated on the upper side of the levelling plate.
Working with the laser target plate/ceiling measure-
ment plate (see figure A)
The laser target plate 9 or the ceiling measurement plate
14 improves the visibility of the laser beam under unfa-
vourable conditions and at longer distances.
The reflective part of the laser target plate 9 improves the
visibility of the laser line. Thanks to the transparent part,
the laser line is also visible from the back side of the laser
target plate.
The ceiling measurement plate 14 (accessory) can also
be used for marking the laser lines. Like the laser target
plate, it has a reflective and a transparent part.
Laser Viewing Glasses (Accessory)
The laser viewing glasses filter out the ambient light. This
makes the red light of the laser appear brighter for the
eyes.
 Do not use the laser viewing glasses as safety gog-
gles. The laser viewing glasses are used for improved
visualisation of the laser beam, but they do not protect
against laser radiation.
Bosch Power Tools
 Do not use the laser viewing glasses as sun glasses
or in traffic. The laser viewing glasses do not afford
complete UV protection and reduce colour perception.

Work Examples

Checking right angles (see figure A)
Position the measuring tool in one corner of the room and
position it so that the 0° laser line runs parallel to the ref-
erence line (e.g. wall). Measure the distance between the
laser line and the reference line directly at the measuring
tool and at the longest possible distance from the measur-
ing tool. Align the measuring tool so that both distances
are identical.
Then measure at at least two different points the distanc-
es between the 90° laser line and the wall. If the distances
to the 90° laser line are identical, the walls are at the right
angle.
Laying of Square Tiles (see figure B)
Position the measuring tool in one corner so that the 0° la-
ser line runs parallel to one wall. Lay the first square tile at
the crossing point of the 0° and the 90° laser lines.
Laying with Diagonal Pattern (see figure C)
Position the measuring tool so that the 45° laser line
marks the diagonal tile joint.
Tile laying in Kitchenettes (see figure D)
Firstly determine the height at which the first tile row be-
gins. Fix the measuring tool with the levelling plate 10 ver-
tically on the wall so that the 90° laser line marks the low-
er edge of the first tile row.
Laying from Edges (see figure E)
Position the measuring tool on the levelling plate 10 at the
edge so that a lateral cut-out 11 of the levelling plate is di-
rectly at the edge. The 0° laser line should run parallel to
one edge. The 90° laser line now marks the lower tile row.

Maintenance and Service

Maintenance and Cleaning

Store and transport the measuring tool only in the sup-
plied protective pouch.
Keep the measuring tool clean at all times.
