Rectifying Errors; Working Advice - Bosch LR 60 Professional Notice Originale

20 | English
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) and the text display (e) LOC will appear. The
CenterLock symbol is displayed on the rotary laser on the
start screen for the corresponding axis.
In the event of changes to the position of the laser receiver
or rotary laser, the inclination is automatically adjusted on
the rotary laser.
Take great care when working with the CenterLock
u
mode that rotary lasers and laser receivers are not
moved unintentionally. Incorrect measurements can
arise from the automatic adjustment of the inclination
with every change of position.
Cancelling CenterLock mode:
To cancel or end the CenterLock mode, press and hold the
CenterFind mode button (17). If the laser beam was already
successfully aligned with the centre line of the laser receiver
at this point, the set inclination remains on the rotary laser
even when CenterLock mode is cancelled.
Troubleshooting:
If the laser beam was unable to find the centre line of the
laser receiver within 2 min (no matter whether at the start of
the mode or after changes to position), 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 CenterLock mode.
If both axes of the rotary laser should be aligned to a laser re-
ceiver, the same centre function must be set on both laser
receivers. A combination of CenterLock mode
and CenterFind mode is not possible.
If CenterFind mode is already set on one axis
and CenterLock mode is started on the other axis, ERR
and CF will appear alternately in the text display (e). Select
CenterLock mode on both laser receivers and re-start the
function.

Anti-strobe protection filter
The laser receiver has electronic filters for strobe light. The
filters protect against, for example, interference from the
warning lights of construction machinery.

Working Advice

Aligning with the spirit level
The laser receiver can be aligned vertically (plumb line) with
the spirit level (7). If a laser receiver is mounted at an angle,
it will give incorrect measurements.
Marking
You can mark the position of the laser beam at the centre
mark (9) on the left and right of the laser receiver when the
beam hits the centre of the reception area (1).
When marking, take care to align the laser receiver so that it
is exactly vertical (with a horizontal laser beam) or horizontal
(with a vertical laser beam), as otherwise the marks are off-
set with respect to the laser beam.
Attaching using the holder (see figure E)
You can use the holder (23) to attach the laser receiver to a
measuring rod (25) (accessory) as well as to other auxiliary
tools with a width of up to 65 mm.
Screw the holder (23) to the mount (11) on the rear side of
the laser receiver with the fastening screw (26).
Loosen the rotary knob (24) on the holder, slide the holder
onto the measuring rod (25) and retighten the rotary
knob (24).
You can use the spirit level (21) to ensure that the
holder (23) is horizontally aligned along with the laser re-
ceiver. If the laser receiver is mounted at an angle, it will give
incorrect measurements.
The centre line reference (22) on the holder is situated at
the same height as the centre marking (9) and can be used
for marking the laser beam.
Attaching using a magnet (see figure F)
If an attachment is not required to be especially secure, the
laser receiver can be attached to steel parts using the
magnets (10).
Corrective measures
Briefly press the on/off button on the rotary laser to close
the error message. Restart the process for establishing
the connection.
If it is not possible to establish a connection, please con-
tact a Bosch customer service agent.
Read and observe the operating instructions for the
GRL 600 CHV or GRL 650 CHVG.
Press any button to close the error message. Check the
position of the rotary laser and laser receiver before re-
starting the function.
