holder 13 with the measuring tool, and not the measuring tool on the wall holder.
When turning, pay attention not to touch the measuring tool, otherwise its position
could be changed. After turning the upper part of the wall holder 13, check if the spirit
level for horizontal alignment 4 is still centred. If this is not the case, correct the align-
ment of the wall holder 13 with adjusting screw 16 until spirit level 4 is centred again.
Working with tripod (recommended): Align the laser beam to the requested height.
Project or check the height at the target location.
Working without tripod: Determine the height difference between the laser beam and
the height at the reference point. Project or check the measured height difference at
the target location.

Checking Horizontal/Vertical Lines with the Spirit Levels (see figure G)

The measuring tool can also be used as a carpenter's spirit level for checking vertical
and horizontal lines, for example to align a washing machine or a refrigerator. Position
the measuring tool with the aluminium supporting surface 2 on the surface to be
checked. When placing on horizontal surfaces, the aluminium supporting surface 2
must face downward, when placing against vertical surfaces, the laser outlet opening
for line operation 5 must face upward.

Working Advice

 For marking, always use only the centre of the laser point or the laser line. The
size of the laser point as well as the width of the laser line change with distance.

Fastening/Aligning with the Wall Holder

With the wall holder 13, the measuring tool can be fastened as follows:
– Line operation: Place the wall holder via its recess on the backside onto a screw
head slightly projecting out of a wall. Fasten the measuring tool with the magnets
8 to the metal surface for line operation 14 of the wall holder. Turn the upper part
of the wall holder to align the measuring tool as required.
– Point operation: Place the wall holder via the tripod mount 17 onto the 1/4" male
thread of the tripod and screw the locking screw of the tripod tight. Align the tripod
roughly. When working without tripod, place the wall holder on a surface that is as
horizontal as possible.
Position the measuring tool with the aluminium supporting surface 2 facing down
on the wall holder. Attach it via the left magnet 8 (viewed from the front side of the
measuring tool) to the metal surface for point operation 15 of the wall holder.
Horizontally align the upper part of the wall holder with adjusting screw 16 of the
wall holder and spirit level 4 of the measuring tool. Turn the upper part of the wall
holder by 90° and repeat the alignment.
