Initial Operation

Protect the measuring tool against mois-
ture and direct sun light.
Do not subject the measuring tool to ex-
treme temperatures or variations in tem-
perature. As an example, do not leave it in
vehicles for longer periods. In case of large
variations in temperature, allow the measur-
ing tool to adjust to the ambient temperature
before putting it into operation. In case of ex-
treme temperatures or variations in tempera-
ture, the accuracy of the measuring tool can
be impaired.
Avoid heavy impact to or falling down of the
measuring tool. After severe exterior effects
to the measuring tool, it is recommended to
carry out an accuracy check (see "Accuracy
Check of the Measuring Tool", page 27) each
time before continuing to work.
Switching On and Off
To switch on the measuring tool, briefly press
the On/Off button 14 or measuring button 10.
When switching on the measuring tool, the laser
beam is not switched on yet.
To switch off the measuring tool, press the
On/Off button 14 for a few seconds.
When no button on the measuring tool is
pressed for approx. 5 minutes, the measuring
tool automatically switches off to save the bat-
teries.
When a measured value has been stored, it is
retained in automatic switch-off mode. When
switching on the measuring tool again, "M" is
indicated in the display.
Measuring Procedure
After switching on, the measuring tool is in the
length measurement mode. Other measuring
modes can be switched to by pressing the re-
spective function/mode button (see "Measuring
Functions", page 22).
After switching on, the rear edge of the measur-
ing tool is preset as the reference level for the
measurement. By pressing the reference level
button 1, the reference level can be changed
(see "Selecting the Reference Level", page 21).
Bosch Power Tools
Upon selection of the measuring function and
the reference level, all further steps are carried
out by pushing the measuring button 10.
With the reference level selected, place the
measuring tool against the desired measuring
line (e.g. a wall).
Push the measuring button 10 to switch on the
laser beam.
Do not point the laser beam at persons or
animals and do not look into the laser beam
yourself, not even from a large distance.
Aim the laser beam at the target surface. Push
the measuring button 10 again to initiate the
measurement.
When the laser beam is switched on permanent-
ly and in the minimum and maximum measure-
ment modes, the measurement already starts
upon first actuation of the measuring button 10.
Typically, the measured value appears after 0.5
and latest after 4 seconds. The duration of the
measurement depends on the distance, the light
conditions and the reflection properties of the
target surface. The end of the measurement is
indicated by a signal tone. The laser beam is
switched off automatically upon completion of
the measurement.
When no measurement has taken place approx.
20 seconds after sighting, the laser beam is
switched off automatically to save the batteries.
Selecting the Reference Level
(see figures B–E)
For measuring, it is possible to select from four
different reference levels:
– the rear edge of the measuring tool (e.g.,
when placing the measuring tool flush
against a wall),
– the rear edge of the positioning pin 15 (e.g.,
for measurements out of corners).
– the front edge of the measuring tool (e.g., as
when measuring from the edge of a table on-
ward),
– the thread 17 (e.g., for measuring with the
tripod).
To select the reference level, press button 1 un-
til the requested reference level is indicated on
the display. Each time after switching on the
measuring tool, the rear end of the measuring
tool is preset as the reference level.
