-- For vertical alignment with spirit level 3, the laser outlet
opening for line operation 5 must face upward and the
aluminium supporting surface 2 of the measuring tool
must face sideward.
Alignment with Laser Line (Line Operation)
Fasten the measuring tool to wall holder 12 (see "Fastening/
Aligning with the Wall Holder", page31), place it against a
wall via the three supporting points 6 or fasten it to an other
magnetic surface with the magnets 9.
Horizontal Alignment (see figures C–D): The laser outlet
opening for line operation 5 must be horizontal and the
aluminium supporting surface 2 of the measuring tool must
face downward. Horizontally align the measuring tool with
spirit level 4. As an example, you can align picture frames or
shelves alongside the horizontal laser line.
Note: Horizontal alignment with the laser line is only possible
on the surface, against which the measuring tool was
placed. Even when the measuring tool was aligned with
the spirit level, the laser line on a transverse wall does
not necessarily run horizontal, and is thus not suitable for
levelling.
Vertical Alignment (see figure D): The laser outlet opening
for line operation 5 must face upward and the aluminium
supporting surface 2 of the measuring tool must face
sideward. Vertically align the measuring tool with spirit
level 3. As an example, you can align top and base cabinets
alongside the vertical laser line.
Alignment off of Reference Points (see figure E): Turn the
measuring tool to any required angle in order to align the
laser line alongside your reference points. As an example,
this can be used to hang picture frames parallel to stairs or
to the incline of a roof.
