Operating Modes

Alignment of X and Y-axis

– Y
– X
(16)
The alignment of the X and Y axes is marked on the housing
above the rotation head. The markings are exactly above the
alignment notches (16) at the bottom edge of the housing
and on the lower handle. The measuring tool can be aligned
along the axes by using the alignment notches.

Operating modes overview

All three operating modes are possible with the measuring
tool in horizontal and vertical position.

Rotational operation

Rotational operation is especially recom-
mended when using the laser receiver. It
is possible to select between different ro-
tational speeds.
Line operation
In this operating mode, the variable laser
beam moves within a defined aperture
angle. This increases the visibility of the
laser beam in comparison to rotational
operation. You can select between differ-
ent aperture angles.
Point operation
In this operating mode, the best visibility
of the variable laser beam can be
reached. For example, it is used to easily
project heights or to check building lines.
Line and point operation are not suitable for use with the
laser receiver (42).
Rotational operation
Each time after switching on, the measuring tool is in rota-
tional operation mode with standard rotational speed (300
–1
min ).
Bosch Power Tools
To switch from line operation to rotational operation, press
the rotational operation button (6) or the rotational opera-
tion button (27) on the remote control.
+ X
The set speed can be seen on the rotational speed indic-
+ Y
ator (h) on the start screen.
When working with the laser receiver, the highest rotational
speed should be set. When not working with the laser re-
ceiver, reduce the rotational speed for improved visibility of
the laser beam and use the laser googles (52).

Line operation/point operation

(16)
To switch to line or point operation, press the line operation
button (5) or the line operation button (29) on the remote
control.
Note: Due to inertia, it is possible for the laser to slightly
move beyond the end point of the laser line.

Functions

Turning the line/point within the rotational plane

In line and point operation, the laser line or the laser point
can be positioned within the rotational plane of the laser. Ro-
tation is possible by 360°.
To rotate anticlockwise, press the button (4) on the
measuring tool or the button for anticlockwise rotation (30)
on the remote control.
To rotate clockwise, press the button (3) on the measur-
ing tool or the button for clockwise rotation (37) on the re-
mote control.

Turning the rotational plane when in the vertical position

When the measuring tool is in the vertical position, it is pos-
sible to rotate the laser point, laser line or rotational plane
around the X-axis for easy sighting out or parallel alignment
in a range of ±8.5%.

To change the rotational speed, press the ro-
tational operation button (6) or the rota-
tional operation button (27) on the remote
control until the required speed is indicated
on the display.
To change the aperture angle, press the line
operation button (5) or the line operation
button (29) on the remote control until the
required operating mode is indicated on the
display. The aperture angle is reduced in
stages each time a button is pressed until
point operation is achieved. Pressing the line
operation button again takes you back to line
operation via rotational operation at moder-
ate speed.
To start the function, press the slope but-
ton (14) on the measuring tool or the slope
button (32) on the remote control. The
menu for setting the slope of the Y‑axis will
appear and the symbol for the Y‑axis will
flash.
