7.3 Checking
7.3.1 Checking the leveling of the horizontal laser
beam 8
1. Place the tool on an even, level surface approx. 20
cm from the wall (A) with the laser beam directed
toward the wall (A).
2. Mark the point of intersection of the laser lines on
the wall (A) with a cross (1).
3. Turn the tool through 180° and mark the point of
intersection of the laser lines on the opposite wall
(B) with a cross (2).
4. Place the tool on an even, level surface approx. 20
cm from the wall (B) with the laser beam directed
toward the wall (B).
5. Mark the point of intersection of the laser lines on
the wall (B) with a cross (3).
6. Turn the tool through 180° and mark the point of
intersection of the laser lines on the opposite wall
(A) with a cross (4).
7. Measure the distances d1 between (1) and (4) and
d2 between (2) and (3).
