The maximum deviation at 20 m must not exceed ±6 mm. Consequently,
the highest and lowest markings can be 12 mm apart. This deviation results
from tolerances of the unit and application when checking the accuracy.
Should the unit be outside of these tolerances, please contact a Bosch
Service Centre.
Operation
Rotation operation
C
To select rotation operation, slide down the ring for the line function 3 and
press the mode selector switch 4. The laser starts with the highest rota-
tional speed. The rotational speed is adjustable in order to enhance the
visibility of the laser beam. Repeated pressing of the mode selector switch
4 reduces the speed in 3 steps to a standstill.
When working with the receiver 17, the highest rotational speed is recom-
mended.
When working without the receiver 17, the lowest rotational speed or line
operation is recommended.
Point operation
After switching on, the unit emits a laser beam which is split into two
beams at a right-angle at the laser exit.
In the horizontal position, this results in a continuous vertical plumb
beam and a variable horizontal beam which is deflected by 90°.
In the vertical position, a continuous plane beam and a variable vertical
beam are available.
By simply turning the prism cap 1, the variable beam is directed manually
to the desired position.
Point operation is particularly well suited for interior work.
Standard Line
D
To select line operation, slide up the ring for line function 3 and press the
mode selector switch 4. The laser starts with the longest line length which
is adjustable depending on the visibility and working area. Repeated
pressing of the mode selector switch 4 reduces the length L of the line in
3 steps to a standstill.
By simply turning the prism cap 1, the line can be moved manually.

Set the desired line length before measuring.
