line in such a manner that its centre runs exactly through 
points 

I

 and 

II

.

– Mark the centre of the laser line at the upper edge of the 

door opening as point 

IV

.

– The difference 

d

 of both marked points 

III

 and 

IV

 results 

in the actual deviation of the measuring tool to the plumb 
line.

– Measure the height of the door opening.

Repeat the measuring procedure for the second vertical laser 
plane. For this, select an operating mode in which a vertical la-
ser plane is generated aside of the measuring tool, and turn 
the measuring tool by 90 ° before beginning with the measur-
ing procedure.

The maximum admissible deviation is calculated as follows:
Doubled height of the door opening x 0.2 mm/m
Example: For a door-opening height of 2 m, the maximum 
deviation may be 2 x 2 m x ± 0.2 mm/m = ± 0.8 mm. Conse-
quently, points 

III

 and 

IV

 may be no more than 0.8 mm 

(max.) apart from each other for each of both measurements.

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 Laser Target Plate

The laser target plate 

15

 increases the visibility of the laser 

beam under unfavourable conditions and at large distances.

The reflective part of the laser target plate 

15

 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.

Working with the Tripod (Accessory)

A tripod offers a stable, height-adjustable measuring support. 
Position the measuring tool with the 1/4" tripod mount 

9

 onto 

the thread of the tripod 

22

 or a commercially available cam-

era tripod. For fastening to a commercially available construc-
tion tripod, use the 5/8" tripod mount 

8

. Tighten the measur-

ing tool with the tripod mounting stud.

Fastening with the Universal Holder (Accessory) 
(see figure D)

With the universal holder 

19

, you can fasten the measuring 

tool, e. g., to vertical surfaces, pipes or magnetizable materi-
als. The universal holder is also suitable for use as a ground tri-
pod and makes the height adjustment of the measuring tool 
easier.

Working with the Measuring Plate (Accessory) 
(see figures A – B)

With the measuring plate 

16

, 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 re-
quired height can be measured and projected at another loca-
tion. This eliminates the necessity of precisely adjusting the 
measuring tool to the height to be projected.

The measuring plate 

16

 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 meas-
uring plate.

Working with the Laser Receiver (Accessory) 
(see figure D)

Under unfavourable light conditions (bright environment, di-
rect sunlight) and for larger distances, use the laser receiver 
for improved finding of the laser lines 

17

. 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.

Applicational examples for the measuring tool can be found 
on the graphics pages.

Maintenance and Service

Maintenance and Cleaning

Store and transport the measuring tool only in the protective 
pouch or in the case.

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.

In case of repairs, send in the measuring tool packed in its 
protective pouch 

18

.
