Bosch LR 60 Professional Notice Originale page 19

To start the CenterFind mode for the Y-axis, press and hold
the CenterFind (17) mode button, together with the Y‑axis
button (15).
Should the laser beam be aligned to both axes at the same
time, CenterFind mode must be started separately on each
laser receiver.
Following the start of CenterFind mode, the rotary head on
the rotary laser moves up and down. During the search pro-
cess, CFX (X‑axis) or CFY (Y‑axis) appears in the text
display (e).
If the laser beam hits the reception area (1) at the height of
the centre line of the laser receiver, the centre line
indicator (h) will appear and XOK (X axis) and YOK (Y axis)
will appear in the text display (e). The value of the incline
that is found is displayed on the rotary laser. CenterFind
mode will be ended automatically.
Cancelling CenterFind mode:
To cancel the CenterFind mode, press and hold the
CenterFind mode button (17).
Troubleshooting:
If the laser beam was unable to find the centre line of the
laser receiver within the pivoting range, ERR appears in the
text display (e) and all LED direction indicators light up.
Press any button on the rotary laser and one on the laser re-
ceiver to close the error messages. Reposition the rotary
laser and laser receiver so that the laser receiver is situated
within the pivoting range of ±8.5 % of the rotary laser. En-
sure that the laser receiver is aligned to the X-axis or Y-axis
so that the laser beam can pass through the reception
area (1) horizontally. Then restart the CenterFind mode.
LR 65 G: If both axes of the rotary laser should be aligned to
a laser receiver, the same centre function must be set on
both laser receivers. A combination of CenterFind mode
and CenterLock mode is not possible.
If CenterLock mode is already set on one axis
and CenterFind mode is started on the other axis, ERR
and CL will appear alternately in the text display (e).
Select CenterFind mode on both laser receivers and re-start
the function.
Inclination determination with CenterFind mode (see
figure D)
Using CenterFind mode, the inclination of a surface can be
measured up to max. 8.5 %. To do this, set up the rotary
laser at one end of the inclined surface in a horizontal posi-
tion on a tripod. The X- or Y-axis of the rotary laser must be
aligned with the inclination to be determined. Switch on the
rotary laser and allow it to level in.
Secure the laser receiver to a measuring rod (25) with the
holder. Place the measuring rod near to the measuring tool
(at the same end of the inclined surface). Align the height of
the laser receiver on the measuring rod so that the laser
beam of the rotary laser is indicated as "centred" ➊.
Then place the measuring rod with the laser receiver at the
other end of the inclined surface at ➋. Ensure that the posi-
tion of the laser receiver on the measuring rod remains un-
changed.
Bosch Power Tools
Start CenterFind mode for the axis to which the inclined
surface is aligned. At the end of CenterFind mode, the in-
clination of the surface is shown on the rotary laser.
CenterLock mode (LR 65 G)
In CenterLock mode, the rotary laser automatically at-
tempts to align the laser beam to the centre line of the laser
receiver by moving the rotation head up and down. In con-
trast to the CenterFind mode, the position of the laser re-
ceiver is continually checked and the inclination of the rotary
laser automatically adjusted. No slope values appear on the
display of the rotary laser.
Alignment is possible for the X‑axis and Y‑axis both when the
rotary laser is in a horizontal position and when it is in a ver-
tical position.
Start CenterLock mode:
Position the rotary laser and laser receiver so that the laser
receiver is situated in the direction of the X-axis or the Y-axis
of the rotary laser. Align the laser receiver so that the re-
quired axis is at a right angle to the reception area (1).
If the laser beam is aligned to both axes, then place a laser
receiver connected to the rotary laser in the direction of the
X- and Y-axis respectively. Each laser receiver must be situ-
ated within the pivoting range of ±8.5 % of the rotary laser.
Switch on the rotary laser in rotational operation.
In the settings menu of the laser receiver, the centre function
must be put in CenterLock (CL) mode. When aligning to two
axes of the rotary laser, this applies to both laser receivers.
To start the CenterLock mode for the X‑axis, either press
and hold the CenterFind (17) mode button, or press and
hold the CenterFind (17) mode button, together with the
X‑axis button (16).
To start the CenterLock mode for the Y-axis, press and hold
the CenterFind (17) mode button, together with the Y‑axis
button (15).
Should the laser beam be aligned to both axes at the same
time, CenterLock mode must be started separately on each
laser receiver.
Following the start of CenterLock mode, the rotary head on
the rotary laser moves up and down. During the search pro-
cess, CLX (X‑axis) or CLY (Y‑axis) appears in the text
display (e).
