Secure the laser receiver (42) to a measuring
rod (43) with the holder. Place the measuring
rod at the base of the slope surface.
Align the height of the laser receiver on the
measuring rod so that the variable laser beam
(8) of the laser level is indicated as “cen-
tered” (see operating instructions for the la-
ser receiver).
Then position the measuring rod with the la-
ser receiver, one after the other, at different
test locations on the slope surface. Make sure
that the laser receiver remains in the same po-
sition on the measuring rod.
If the slope of the plane is correct, the laser
beam will be indicated as “centered” at all
test locations.
