Sighting with the Alingment Aid (see figure E)
With the alignment aid 7, sighting over larger distances is a lot
easier. For this, look alongside the aligning aid on the top side
of the measuring tool. The laser beam runs parallel to this line
of sight.
Working with the Tripod (see figure C)
The use of a tripod is particularly necessary for larger distanc-
es. Position the measuring tool with the 1/4" thread 14 onto
the quick-change plate of the tripod 20 or a commercially
available camera tripod. Tighten the measuring tool with the
locking screw of the quick-change plate.
When positioning the tripod, observe that the measurement
will take place beginning from the rear or front edge of the
measuring tool, depending on the selected reference level.
Troubleshooting Causes and Corrective Meas-
ures
The measuring tool monitors the correct
function for each measurement. When a de-
fect is determined, 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 measuring section
with a length of approx. 3 to 10 metres; its length must be
precisely known (e.g. the width of a room or a door open-
ing). 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 ±2.0 mm (max.). Log the measure-
ments, 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 19 in particular, with the same
care as required for eye glasses or the lens of a camera.
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 24.
Cause Corrective Measure
Temperature warning indicator (b) flashing; measure-
ment not possible
The measuring tool is outside the
operating temperature range from
10 °C to + 50 °C (in the function
continuous measurement up to
+40 °C).
Wait until the measuring
tool has reached the op-
erating temperature
Battery low indicator (a) appears
Battery voltage decreasing (meas-
urement still possible)
Replace batteries
Battery low indicator (a) flashing; measurement not pos-
sible
Battery voltage too low Replace batteries
Error and––––” indication in display
The angle between the laser beam
and the target is too acute.
Enlarge the angle be-
tween the laser beam
and the target
The target surface reflects too in-
tensely (e.g. a mirror) or insuffi-
ciently (e.g. black fabric), or the
ambient light is too bright.
Work with the laser tar-
get plate 22 (accessory)
The laser beam outlet 18 or the re-
ception lens 19 are misted up
(e.g. due to a rapid temperature
change).
Wipe the laser beam out-
let 18 and/or the recep-
tion lens 19 dry using a
soft cloth

Divide calculation into
intermediate steps
“Error” indication flashes at in display (top)
Addition/Subtraction of measured
values with different units of meas-
ure
Only add/subtract
measured values with
the same units of meas-
ure
Unreliable measuring result
The target surface does not reflect
correctly (e.g. water, glass).
Cover off the target sur-
face
The laser beam outlet 18 or the re-
ception lens 19 are covered.
Make sure that the laser
beam outlet 18 or the re-
ception lens 19 are un-
obstructed
Measuring result not plausible
Wrong reference level set Select reference level
that corresponds to
measurement
Obstruction in path of laser beam Laser point must be
completely on target
surface.
