– Turn the measuring tool around by 180°, allow it to level in
and mark the centre point of the laser beam on the oppo-
site wall B (point II).
– Without turning the measuring tool, position it close to wall
B. Switch the measuring tool on and allow it to level in.
A
– Align the height of the measuring tool (using the tripod or
by underlaying, if required) in such a manner that the cen-
tre point of the laser beam is projected exactly against the
previously marked point II on wall B.

d
– Rotate the measuring tool by 180° without changing the
height. Allow it to level in and mark the centre point of the
laser beam on wall A (point III). Take care that point III is
as vertical as possible above or below point I.
– The difference d of both marked points I and III on wall A
results in the actual height deviation of the measuring tool
alongside the longitudinal axis.
On the measuring distance of 2 x 20 m = 40 m, the maximum
allowable deviation is: 40 m x ±0,3 mm/m = ±12 mm.
Thus, the difference d between points I and III may not ex-
ceed 12 mm (max.).

Working Advice

 Always use the centre of the laser point for marking.
The size of the laser point changes with the distance.
Attaching with the Holder
To fasten the measuring tool on the holder 8, screw the lock-
ing screw 9 of the holder into the 1/4" tripod mount 6 on the
measuring tool and tighten. To rotate the measuring tool on
the holder, slightly loosen the screw 9.
– Rotate the measuring tool on the holder 8 sideward or
toward the rear to make the bottom plumb beam visible.
– Rotate the measuring tool on the holder 8 to project
heights with the horizontal laser beam.

With the holder 8, the measuring tool can be attached as
follows:
– Mount the holder 8 to the tripod 18 or a commercially
available camera tripod via the 1/4" tripod mount 13. For
fastening to a commercially available construction tripod,
use the 5/8" tripod mount 14.
– The holder 8 can be fastened to steel parts via the magnets
12.
– The holder 8 can be fastened to drywalls or wood walls
with screws. For this, insert screws with a minimum length
of 60 mm into the screw holes 10 of the holder.
– The holder 8 can also be fastened to pipes or similar beams
using a commercially available strap by threading it
through the opening 11 for strap attachment.
Working with the Tripod (Accessory)
A tripod 18 offers a stable, height-adjustable measuring sup-
port. Place the measuring tool via the tripod mount 6 onto the
1/4" male thread of the tripod and screw the locking screw of
the tripod tight.
Working with the Measuring Plate (Accessory)
With the measuring plate 15, it is possible to project the laser
mark onto the floor or the laser height onto a wall.
With the zero field and the scale, the offset or drop to the re-
quired height can be measured and projected at another loca-
tion. This eliminates the necessity of precisely adjusting the
measuring tool to the height to be projected.
The measuring plate 15 has a reflective coating that enhances
the visibility of the laser beam at greater distances or in
intense sunlight. The brightness intensification can be seen
only when viewing, parallel to the laser beam, onto the meas-
uring plate.
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 visualisa-
tion 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 perception.

Maintenance and Service

Maintenance and Cleaning

Store and transport the measuring tool only in the supplied
protective pouch.
Keep the measuring tool clean at all times.
Do not immerse the measuring tool in water or other fluids.
Wipe off debris using a moist and soft cloth. Do not use any
cleaning agents or solvents.
Regularly clean the surfaces at the exit opening of the laser in
particular, and pay attention to any fluff or fibres.
In all correspondence and spare parts orders, please always
include the 10-digit article number given on the type plate of
the measuring tool.
