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).

Bosch Power Tools
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).
