Cause
The indications "ERROR" and "–––––" are
indicated in the display
The angle between the
laser beam and the target
is too acute.
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.
The laser beam outlet 27
or the reception lens 26
are misted up (e.g. due to
a rapid temperature
change).
Calculated value is great-
er than 999999 m/m
The indication "ERROR" flashes at the top in
the display
Addition/Subtraction of
measured values with
different units of measure
Measuring result not plausible
The target surface does
not reflect correctly
(e.g. water, glass).
The laser beam outlet 27
or the reception lens 26
are covered.

Laser point must
be completely on
target surface.
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.
