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 Alignment Plate
With the alignment plate 12, the measuring tool can be
aligned by a reference line or the vertical laser line can be in-
dicated at an angle of 45° or 90° to a reference line.
Position the measuring tool via the tripod mount 6 onto the
pin 16 of the alignment plate. Position it in such a manner on
the alignment plate that the vertical laser line (depending on
the requested angle) runs centrally through the alignment aid
13, 14 or 15.
Align the alignment plate 12 with the corresponding align-
ment aids 13, 14 or 15 to the desired reference line.
Working with the Measuring Plate (Accessory)
(see figures E–F)
With the measuring plate 20, it is possible to project the laser
mark onto the floor or the laser height onto a wall.
With the zero field and the scale, the offset or drop to the
required height can be measured and projected at another
location. This eliminates the necessity of precisely adjusting
the measuring tool to the height to be projected.
The measuring plate 20 has a reflective coating that enhances
the visibility of the laser beam at greater distances or in
intense sunlight. The brightness intensification can be seen
only when viewing, parallel to the laser beam, onto the mea-
suring plate.
Working with the Tripod (Accessory)
A tripod offers a stable, height-adjustable measuring support.
Place the measuring tool via the tripod mount 6 onto the 1/4"
male thread of the tripod and screw the locking screw of the
tripod tight.
Working with the Laser Receiver (Accessory)
(see figure G)
Under unfavourable light conditions (bright environment,
direct sunlight) and for larger distances, use the laser receiver
for improved finding of the laser lines 21. When working with
the laser receiver, switch the pulse function on (see "Pulse
Function", page 14).
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 goggles.
The laser viewing glasses are used for improved visualisa-
tion of the laser beam, but they do not protect against laser
radiation.
 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.
Bosch Power Tools
Work Examples (see figures H–K)
Laying Flooring Plates at a 45° Angle (see figure J)
Position the measuring tool via the tripod mount 6 onto the
pin 16 of the alignment plate. Position it in such a manner on
the centred protrusion of the alignment plate 12 that the ver-
tical laser line runs centrally through the alignment aid 15.
Then, align the alignment plate with the alignment aids 13 or
14 with regard to the reference line.
For cross line or in vertical operation, the vertical laser line on
the floor indicates a 45° angle to the reference line. Align the
flooring plates with regard to this line.
Projecting Plumb Points to the Ceiling (see figure K)
Draw two lines crossed at a right angle through the point that
you want to project to the ceiling. Place the alignment plate
12 onto the crossed lines and align it with the alignment aids
13 and 14 on the cross.
Position the measuring tool via the tripod mount 6 onto the
pin 16 of the alignment plate. Position it in such a manner on
one of the two outer protrusions on the alignment plate that
the vertical laser line runs centrally through the correspond-
ing alignment aid 13 or 14. Select vertical operation and draw
the centre of the line running across the measuring tool to the
ceiling.
Turn the measuring tool on the alignment plate by 90°. Pay at-
tention not to move the position of the alignment plate. After
levelling in, draw the cross point of the vertical laser line to the
already drawn line. The cross point of both lines is the projected
plumb point.

Maintenance and Service

Maintenance and Cleaning

Store and transport the measuring tool only in the protective
pouch 17 or in the case 18.
Keep the measuring tool clean at all times.
Do not immerse the measuring tool in water or other fluids.
Wipe off debris using a moist and soft cloth. Do not use any
cleaning agents or solvents.
Regularly clean the surfaces at the exit opening of the laser in
particular, and pay attention to any fluff or fibres.
If the measuring tool should fail despite the care taken in man-
ufacturing and testing procedures, repair should be carried
out by an authorised after-sales service centre for Bosch pow-
er tools. Do not open the measuring tool yourself.
In all correspondence and spare parts orders, please always
include the 10-digit article number given on the type plate of
the measuring tool.
For repairs, only send in the measuring tool in the protective
pouch 17 or in the case 18.
