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 at the base of the inclined
surface near to the measuring tool. 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
upper end of the inclined surface at ➋. Ensure that the posi-
tion of the laser receiver on the measuring rod remains un-
changed.
Start centre line mode for the axis to which the inclined sur-
face is aligned. At the end of centre line mode, the inclina-
tion of the surface is shown on the rotary laser.
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.
Practical 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 height 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 a spirit level (21) to ensure that the holder (23)
is horizontally aligned along with the laser receiver. If a laser
receiver is mounted at an angle, it will give incorrect meas-
urements.
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 mag-
nets (10).
Corrective measure
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 contact
a Bosch customer service agent.
Read and observe the operating instructions for the
GRL 600 CHV.
Press any button to terminate the function. Check the posi-
tion of the rotary laser and laser receiver before restarting
the function.
