lnitial
Operation
.
Protect
the tool
against moisture
and
direct sun irradiation.
.
Do not
subject the tool
to extreme
temperatures
or variations
in
temperature.
As
an example, do not leave
it in vehicles for
longer
periods.
ln case of
large
variations in
temperature,
allow
the
tool to adjust
to the ambient
temperature
before
putting
it into
operation.
ln
case of extreme
temperatures
or
variations
in temperature,
the accuracy
of
the tool
can be impaired.
.
Avoid heavy impact
or falling
of the tool.
After heavy
exterior impact
on the tool,
an
accuracy
check should
always be carried
out before
continuing to work
(see
"Leveling
Accuracy").
.
Switch the tool off
during transport.
When
switching off, the leveling
unit,
which
can be damaged in
case of intense
movement, is
locked.
Switching On and Off
To
switch on the tool,
slide
the
On/Off switch 3
to the "On"
position.
lmmediately
after
switching
on,
the
tool sends laser
beams out
of the exit openings 1.
.
Do not
point
the
laser
beam at
persons
or animals and do not look into the laser
beam
yourself,
not
even
from
a large
distance.
To
switch off the
tool, slide the On/Off switch
3
to the
"off'
position.
When
switching otf, the
leveling
unit
is locked.
.
Do not leave the
switched on measuring
tool
unattended and switch the tool off
after use. Other
persons
could be blinded
by the
laser
beam.
The tool
switches off automaically
after an
operating duration of
30
minutes.
Operatinq
Modes
The tool has total
of six operation modes
that
can be switched through in
sequence
ln any
of the first three operation modes
(Automatic
Self-Leveling), if the tool is tilted
more than 4' in
any direction, the laser lines
will
blink slowly
(Out-Of-Level
error) to
indicate
the tool is currently not
self-leveling.
Bring
the tool to
a
more
level
position
before
continuing work.
Operation
-
Horizontal
operation
"-":
Produces
a
horizontal laser
line,
-
Vertical
operation
"1":
Produces
a vertical
laser line,
-
Cross-line
operation "+": Produces
a
horizontal
and vertical laser line.
The
tool
has
three Slope modes
that can be
switched through in sequence.
The operating
mode
button
4 will
illuminate while
Slope
modes are selected. The
tool will not indicate
Out-Of-Level
(OOL)
in
Slope mode.
-
Horizontal operation
"-" produces
a
horizontal
laser Iine.
-
Vertical operation
"1" produces
a vertical
laser
line.
-
Cross-Line operation
"+" produces
vertical
and horizontal laser lines.
After
switching on, the tool
is
in
cross-line
operating mode. To change the
operating
mode,
press
the
operating mode button 4.
Automatic Levelinq
Working with Automatic Leveling
Position the tool on a ievel
and
firm
support,
attach it to
the magnetic
bracket 9 or to a
tripod.
After switching on, the leveling f
unction
automatically compensates irregularities
within the
self-leveling
range
of
+4'.
The
leveling is f inished
as soon as the laser
beams do not move anymore.
lf
the automatic
leveiing f
unction is not
possible,
e.g. because the sudace
on
which
the measuring tool stands deviates by more
than 4" from the horizontal
plane,
the laser
beams flash slowly. ln this case, bring the tool
to the
level
position
and
r,vait
for the self-
leveling to take
place.
As soon
as the tool
is
within the seltleveling range of
+4',
the laser
lines light
up continuously again.
ln case of
ground
vibrations
or
position
changes
during opei'ation, the tool is
automatically
leveled
in again. To
avoid
errors, check
the
position
of the horizontal and
vertical laser line with regard to the reference
points
upon
re-leveling.
