The measuring tool monitors the 
correct function for each meas-
urement. When a defect is deter-
mined, only the symbol shown 
aside flashes in the display. In this 

case, or when the above mentioned corrective 
measures cannot correct an error, have the 
measuring tool checked by an after-sales service 
agent for Bosch power tools.

Accuracy Check of the Measuring Tool

The accuracy of the measuring tool can be 
checked as follows:
– Select a permanently unchangeable measur-

ing section with a length of approx. 1 to 10 
metres; its length must be precisely known 
(e. g. the width of a room or a door opening). 
The measuring distance must be indoors; the 
target surface for the measurement must be 
smooth and reflect well.

– Measure the distance 10 times after another.
The deviation of the individual measurements 
from the mean value must not exceed 

±

1.5 mm 

(max.). Log the measurements, so that you can 
compare their accuracy at a later point of time.

Maintenance and Service

Maintenance and Cleaning

Store and transport the measuring tool only in 
the supplied protective pouch.
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.
Maintain the reception lens 

26

 in particular, 

with the same care as required for eye glasses 
or the lens of a camera.

The indications “ERROR” and “– – – – – ” are 
indicated in the display

The angle between the 
laser beam and the target 
is too acute.

Enlargen the angle 
between the laser 
beam and the 
target

The target surface reflects 
too intensely (e. g. a mir-
ror) or insufficiently (e. g. 
black fabric), or the ambi-
ent light is too bright.

Work with the 
laser target plate

The laser beam outlet 

27

or the reception lens

are misted up (e. g. due to 
a rapid temperature 
change).

Wipe the laser 
beam outlet

and/or the recep-
tion lens

Addition/Subtraction of 
measured values with 
different units of measure

Only add/subtract 
measured values 
with the same 
units of measure

Measuring result not plausible

The target surface does 
not reflect correctly 
(e. g. water, glass).

Cover off the 
target surface

The laser beam outlet 

27

or the reception lens 

26

are covered.

Make sure that the 
laser beam outlet 

27

 or the recep-

tion lens 

26

 are 

unobstructed

Wrong reference level set Select reference 

level that corre-
sponds to meas-
urement

Obstruction in path of 
laser beam

Laser point must 
be completely on 
target surface.
