align the laser beam to the reference points. In this manner, as
an example, picture frames can be hung parallel to a stairway or
ceiling pitch.
Checking Horizontal/Vertical Lines with the Spirit Levels
(see figure E)
The tool can be used as a contractors level for checking
horizontal or vertical lines, e.g., for the level set-up of a washer
or a refrigerator. Position the tool with the aluminium supporting
surface 8 facing against the surface to be checked. When
positioning against horizontal surfaces, the aluminium
supporting surface 8 must face downward. When positioning
against vertical surfaces, the exit opening for the laser beam 9
must face upward.
Working Advice
• Keep the adhesive tape strips 4 out of the reach of
small children. Children could mistake the strips with
chewing gum.
Mounting to a Wall
Four fastening methods are available for fastening the wall holder to
different surfaces:
• Fastening with Adhesive Tape Strips (see figure F): With the
removable adhesive tape strips 4, the wall holder can be
fastened to sensitive or delicate sturctural materials without
causing damage to them. The structural surface must be
straight, firm, dry, grease-free and have a temperature of at least
15 °C . Pull off one of the protective foils from an adhesive tape
strip ( ) and position the adhesive tape strip onto the back
side of the wall holder ( ) in such a manner that its end
projects out. Pull off the second protective foil ( ) and firmly
press the wall holder with the adhesive tape strip against the
structural surface ( ) for at least five seconds. To remove the
wall holder, pull out the adhesive tape strip by the projecting end
slowly and as parallel as possible to the structural surface ( ).
• Fastening with Pins (see figure G): With the pins 2 provided,
the wall holder can be fastened to drywall or wooden walls.
Insert the pins through the openings in the wall holder as shown
in the figure.
• Fastening with a Screw: Place the wall holder 1 via the
opening on the back side onto a screw that projects lightly out of
the wall.
• Fastening with Adhesive Tape (see figure H): The wall holder
can also be fastened with commercially available adhesive tape
(not included in the delivery scope) as shown in the figure.
