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

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-

Replace batteries

Battery low indicator (a) flashing; measurement not pos-

“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.
