behind, looking toward the point of intersection of the
laser lines.
1. Place the tool on a smooth, horizontal surface at
the edge of a room with a length of at least 10 m
and width of at least 5 m (or with the same 2:1
size ratio).
NOTE The floor surface must be smooth and
level.
2. Switch on all laser beams.
3. Fix a target plate at a distance of at least 10 m
from the tool so that the point of intersection
of the laser lines strikes the center of the target
plate.
4. Using a second target plate, mark a reference
cross on the floor at a distance of 5 m (measure
the distance) from the first target plate.
The vertical line on the second target plate must
run exactly through the middle of the vertical
laser line.
5. Fix the second target plate at a distance of 5 m
from the reference point (marked at step 4) so
that the vertical line on the second target plate
lies exactly in the middle of the vertical laser line.
6. Now position the tool with the lower plumb beam
exactly on the center of the reference cross (from
step 4) so that the vertical line on the first target
plate (from step 3) runs exactly through the
middle of the vertical laser line.
7. Fix another target plate or a piece of stout paper
at a distance of 5 m from the perpendicular beam,
half-way, in the middle. Mark the mid point (d1)
of the right perpendicular beam.
8. Pivot the tool clockwise through 90° (as seen
from above). The lower plumb beam must remain
in the center of the reference cross and the center
of the right perpendicular beam must lie exactly
on the vertical line on the second target plate
(from step 5).
9. Mark the mid point (d2) of the right perpendicular
beam on the second target plate (from step 5).
10. Mark the mid point (d3) of the point of intersec-
tion of the laser lines on the target plate or paper
(from step 7).
NOTE The horizontal distance between d1 and
d3 must be no greater than 3 mm at a working
distance of 5 m.

11. Pivot the tool clockwise through 180° (as seen
from above). The lower plumb beam must remain
in the center of the reference cross and the center
of the right perpendicular beam must lie exactly
on the vertical line on the first target plate (from
step 3).
12. Then mark the mid point (d4) of the left perpen-
dicular beam on the second target plate (from
step 5).
NOTE The horizontal distance between d2 and
d4 must be no greater than 3 mm at a working
distance of 5 m.
NOTE If d3 is to the right of d1, the sum of the
horizontal distances d1-d3 and d2-d4 must be
no greater than 3 mm at a working distance of
5m.
NOTE If d3 is to the left of d1, the difference
between the horizontal distances d1-d3 and d2-
d4 must be no greater than 3 mm at a working
distance of 5m.
7.3.5 Checking the curvature of the horizontal
lines 15 16
1. Place the tool at the edge of a room with a length
of at least 10 m.
NOTE The floor surface must be smooth and
level.
2. Switch on all laser beams.
3. Set up a target plate at a distance of at least 10 m
from the tool, so that the point of intersection of
the laser lines lies in the center of the target plate
(d0) and the vertical line on the target plate runs
exactly through the middle of the vertical laser
line.
4. Mark the mid point of the lower plumb beam on
the floor (reference cross).
5. Pivot the tool clockwise through 45° (as seen
from above). The lower plumb beam must remain
on the center of the reference cross.
6. Then mark the point (d1) on the target plate
where the horizontal laser line strikes the vertical
line on the target plate.
7. Pivot the tool counterclockwise through 90°. The
lower plumb beam must remain on the center of
the reference cross.
