– by switching the measuring tool on and off via the on/off
button (11)
– or by pressing the ▲/ (4) and ▼/ (3) buttons on the
measuring tool at the same time.

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 recommen-
ded when using the laser receiver. It is possible
to select between different rotational speeds.
Line operation
In this operating mode, the variable laser beam
moves within a defined aperture angle. This in-
creases the visibility of the laser beam in com-
parison to rotational operation. You can select
between different aperture angles.
Point operation
In this operating mode, the best visibility of the
variable laser beam can be reached. For ex-
ample, 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 (41).
Rotational operation
Each time after switching on, the measuring tool is in rota-
tional operation mode with standard rotational speed
−1
(600 min ).
Bosch Power Tools
To switch from line operation to rotational operation, press
the rotational operation button (6) or the rotational opera-
tion button (26) on the remote control.
+ X
The set speed can be seen on the rotational speed
indicator (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-
+ Y
ceiver, reduce the rotational speed for improved visibility of
the laser beam and use the laser googles (50).

Line operation/point operation

To switch to line or point operation, press the line operation
button (5) or the line operation button (28) on the remote
control.
(16)
At 360°, the measuring tool is again in rotational operation.
The rotational speed is the last set speed.
Note: Due to inertia, it is possible for the laser to slightly
move beyond the end point of the laser line.

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 (29)
on the remote control.
To rotate clockwise, press the button (3) on the measur-
ing tool or the button for clockwise rotation (36) 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 rotate the rotational plane, press the ▲ button (4) or the
▼ button (3) on the measuring tool or the up (30) or
English | 43
To change the rotational speed, press
the rotational operation button (6) or
the rotational operation button (26)
on the remote control as many times
as needed 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 (28) on the re-
mote control until the required operat-
ing mode is indicated on the display.
The aperture angle is reduced in
stages each time a button is pressed
until point operation is achieved.
To start the function, press the slope
button (14) on the measuring tool or
the slope button (31) 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.
