Working Advice
 Always place the measuring tool level on the floor or fasten it plane
against the wall. When placing down or fastening unevenly, the angle will not
be precisely 90°.
 When laying floor tiles, do not use spirit levels 3 and 5 for levelling of the
measuring tool. Spirit levels 3 and 5 are used only for alignment against
walls. When laying floor tiles, the bubbles of the spirit levels can be within the
marks, without the measuring tool being level.
 Always use the centre of the laser line for marking. The width of the laser
line changes with the distance.
 Never use the laser lines that the measuring tool standing on the floor
projects on the wall for alignment. The measuring tool is not self-levelling.
Therefore, the line on the wall is distorted.
 The reference point for alignment of tiles is the intersecting point P of
the laser lines, directly in front of the measuring tool. To project an an-
gle, the measuring tool must be rotated at this intersecting point, see
figure E.
 Position the measuring tool only on a clean wall holder 13. The measuring
tool cannot stand level on an uneven, soiled wall holder surface, which could
lead to faulty measuring results.
Positioning the Measuring Tool
When working on the floor, place down the measuring tool with the bottom
plate 10 facing the floor. Place the T-edge 7 of the tool against a wall so that the
0° laser line runs parallel to the reference line (e.g. a wall), see figure A. Meas-
ure the clearance between laser line and reference line directly at the measuring
tool and as far away as possible from the measuring tool. Align the measuring
tool in such a manner that both clearances are equal.
When working on a wall, firstly fasten the wall holder 13 to the wall, e.g. by
placing the wall holder via an opening onto a screw that lightly projects out of
the wall. Then tighten the screw to secure the wall holder, see figure D. Fasten
the measuring tool with the magnets 8 via the bottom plate 10 against the wall
holder 13.
Spirit levels 3 and 5 aid in precisely positioning the laser line against the wall.
– For horizontal alignment, the bubble must be within the marks of the spirit
level 3 which lays in the extension of the horizontal laser line, see figure A.
– For diagonal alignment, the bubble must be within the marks of spirit
level 5, see figure B.
Laser Viewing Glasses (Accessory)
The laser viewing glasses filter out the ambient light. This makes the red light of
the laser appear brighter for the eyes.
 Do not use the laser viewing glasses as safety goggles. The laser viewing
glasses are used for improved visualisation of the laser beam, but they do not
protect against laser radiation.
 Do not use the laser viewing glasses as sun glasses or in traffic. The laser
viewing glasses do not afford complete UV protection and reduce colour per-
ception.
Work Examples
Laying of Square Tiles (see figure A)
Position the measuring tool in a corner in such a manner that the 0° laser line
runs parallel to a wall and the T-edge 7 of the measuring tool faces against the
wall. Lay the first square tile in such a manner that any right-angled side of the tile
is seated flush on the 0° and the 90° laser line.
