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.

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

.
