– Structured surfaces (e. g., roughcast, natural stone).
If required, use the laser target plate 20 (accessory) on these 
surfaces.
Furthermore, faulty measurements are also possible when 
sighting inclined target surfaces.
Also, air layers with varying temperatures or indirectly re-
ceived reflections can affect the measured value.
Accuracy Check of the Distance Measurement
The accuracy of the distance measurement can be checked as 
follows:
– Select a permanently unchangeable measuring 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 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 mm (max.). Log the measure-
ments, so that you can compare their accuracy at a later point 
of time.
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 14 onto 
the quick-change plate of the tripod 18 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 6 (the reference level is the 
thread).
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.
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 12 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 17.

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-

ciently (e. g. black fabric), or the 
ambient light is too bright.Work with the laser tar-

Wrong reference level set Select reference level 
that corresponds to 
measurement
Obstruction in path of laser beam Laser point must be
