The difference
d between
point

and the
center of the laser line at the
upper edge of
the

actual
deviation of the tool from

The maximum
permitted
deviation dmax is
calculated as follows:
dmax
=
double height of the door opening
x

Example: With
a

opening
height
of 2
meters, the maximum
permitted
deviation is
dmax
=

Working Advice
.
Always
use the center of the laser line
for marking. The width of the laser line
changes
with
the distance.
beam at
greater
distances or in intense
sunlight.
The
brightness
intensification
can
be seen only
when viewing,
parallel
to the
Iaser beam, onto the measuring
plate.
Working with a Tripod
(Accessory)
A tripod offers a stable, height-adjustable
measuring
support.
Place the tool via
the
tripod mount 2 onto the 114" male thread of
the tripod and screw
the locking
screw of the
tripod tight.
Laser Viewing Glasses
(Accessory)
The laser viewing
glasses
17, filter out the
ambient
light. This makes the red light
of
the
Iaser appear brighter for the eyes"
.
Do not use the laser viewing
glasses
as
safety
goggles.
The laser viewing
glasses
are used
for improved visualization of the
laser beam, but
they
do
not
protect
against
laser radiation.
.
Do not
use
the laser viewing
glasses
as
sun
glasses
or in tralf ic. The laser
viewing
glasses
do
not
afford complete UV
protection
and
reduce
colour
perception.
Use
with
Attachments
Attaching with
the
Magnetic
Bracket
To fasten the tool on the magnetic
bracket 9,
screw the locking screw 10
of
the magnetic
bracket into the 1/4" lripod mount 2 on the tool
and tighten. To rotate the measuring tool on
the magnetic
bracket, slightly loosen the
screw 10.
With the magnetic bracket 9, the tool can be
attached as follows:
-
lVlount the magnetic bracket
9
to the tripod
19
or a commercially available camera
tripod via
lhe
114"
tripod mount 14. For
fastening to a commercially
available
construction tripod, use the 5/8" tripod
mount 1
5.
-
The magnetic
bracket 9 can be fastened to
steel
parts
via the magnets 13.
-
The magnetic
bracket 9 can be fastened to
drywalls or wood walls with
screws.
For
this, insert
screws
with
a minimum length of
2" into the screw holes 11
of
the magnetic
bracket.
-
The magnetic
bracket 9 can also be
fastened to
pipes
or similar beams using a
commercially available strap by threading it
through the opening 12 for
strap
attachment.
Working with
the Measuring Plate
(Accessory)
(see
figures
A
-
B)
With the laser target
plate
18, 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 required height
can be measured
and
projected
at another location. This
eliminates the necessity
of
precisely
adjusting
the tool to
the height to be
projected.
The laser target
plate
18 has a reflective
coating that enhances the visibility
of the laser
