Measuring with the Positioning Pin
(see figures C, F and G)
The positioning pin 15 is suitable for measuring out of corners
(diagonal within a space) or from hard to reach areas, such as
from roller-shutter rails.
Slide the latch 16 of the positioning pin sideward in order to
swivel out the pin.
Set the corresponding reference level for measurements with
the positioning pin by pushing button 1.
The positioning pin 15 swivels back in again by pushing it to-
ward the housing to the stop. The pin automatically locks in
place.
Aligning with the Spirit Level
The spirit level 6 allows for simple levelling of the measuring
tool. This allows for easier sighting of target surfaces, espe-
cially over longer distances.
In combination with the laser beam, the spirit level 6 is not
suitable for levelling.
Sighting with the Alingment Aid (see figure K)
With the alignment aid 8, 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 (Accessory)
The use of a tripod is particularly necessary for larger distanc-
es. Position the measuring tool with the 1/4" thread 17 onto
the quick-change plate of the tripod 23 or a commercially
available camera tripod. Tighten the measuring tool with the
locking screw of the quick-change plate.
Set the corresponding reference level for measurement with
a tripod by pushing button 1 (the reference level is the
thread).
Troubleshooting
Measures
Cause
Temperature warning indicator (c) flashing; measure-
ment not possible
The measuring tool is not within
the operating temperature range
of –10 °C to +50°C; for continu-
ous measurements (functions
minimum/maximum measure-
ment) to +40 °C.
Battery low indicator (b) appears
Battery voltage decreasing
(measurement still possible).
Battery low indicator (b) flashing; measurement not possible
Battery voltage too low
"Error" and "––––" indication in display
The angle between the laser beam
and the target is too acute.

Cause
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.
The laser beam outlet 21 or the
reception lens 22 are misted up
(e.g. due to a rapid temperature
change).

Measuring result not plausible
The target surface does not reflect
correctly (e.g. water, glass).
The laser beam outlet 21 or the re-
ception lens 22 are covered.
Wrong reference level set
Obstruction in path of laser beam Laser point must be
The measuring tool monitors the correct
function for each measurement. When a
defect is determined, only the symbol
shown aside flashes in the display. In this
case, or when the above mentioned correc-
tive 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.
Corrective Measure
Work with the laser tar-
get plate 25 (accessory)
Wipe the laser beam out-
let 21 and/or the recep-
tion lens 22 dry using a
soft cloth
Divide calculation into
intermediate steps
Only add/subtract meas-
ured values with the
same units of measure
Cover off the target
surface
Make sure that the laser
beam outlet 21 or the
reception lens 22 are
unobstructed
Select reference level
that corresponds to
measurement

surface.
