Inserting/Replacing the Batteries

Alkali-manganese batteries are recommended for the meas-
uring tool.
To open the battery lid 7, press the latch of the battery lid 8 in
the direction of the arrow and remove the battery lid. Insert
the supplied batteries. When inserting, pay attention to the
correct polarity according to the representation on the inside
of the battery compartment.
When the battery indication 4 flashes, the batteries are weak.
When the battery indication flashes for the first time, the
measuring tool can still be operated for approx. 1 h.
Always replace all batteries at the same time. Only use batter-
ies from one brand and with the identical capacity.
 Remove the batteries from the measuring tool when
not using it for extended periods. When storing for ex-
tended periods, the batteries can corrode and self-dis-
charge.
Working with the Rotating Mount RM 1
(see figures J1–J2)
You can use the rotating mount 18 to rotate the measuring
tool 360° around a central, always visible plumb point. This
enables you to set up the laser lines precisely, without having
to change the position of the measuring tool.
– Place the measuring tool with the guide groove 21 on the
guide rail 22 of the rotating mount 18 and slide the meas-
uring tool to the stop onto the platform.
To disconnect, pull the measuring tool in the opposite di-
rection from the rotating mount.
Positioning possibilities of the rotating mount:
– standing on a flat surface,
– screwed to a vertical surface,
– on metallic surfaces using the magnets 24,
– on metallic ceiling strips using the ceiling clip 19.
Operation

Initial Operation

 Protect the measuring tool against moisture and direct
sun light.
 Do not subject the measuring tool to extreme tempera-
tures or variations in temperature. As an example, do
not leave it in vehicles for a long time. In case of large vari-
ations in temperature, allow the measuring tool to adjust to
1 609 92A 2K0 | (13.4.16)
the ambient temperature before putting it into operation.
In case of extreme temperatures or variations in tempera-
ture, the accuracy of the measuring tool can be impaired.
 Avoid heavy impact or falling of the measuring tool. Af-
ter heavy exterior impact on the measuring tool, an accura-
cy check should always be carried out before continuing to
work (see "Levelling Accuracy").
 Switch the measuring tool off during transport. When
switching off, the levelling unit, which can be damaged in
case of intense movement, is locked.
Switching On and Off
To switch on the measuring tool, slide the On/Off switch 2 to
the " on" position (when working without automatic level-
ling) or to the " on" position (when working with automat-
ic levelling). Immediately after switching on, the measuring
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 measuring tool, slide the On/Off switch 2 to
the "Off" position. When switching off, the levelling unit is
locked.
When exceeding the maximum permitted operating tempera-
ture of 50 °C, the measuring tool switches off to protect the
laser diode. After cooling down, the measuring tool is ready
for operation and can be switched on again.
Automatic Shut-off
When no button on the measuring tool is pressed for approx.
120 minutes, the measuring tool automatically switches off
to save the batteries.
– To switch the measuring tool back on after automatic shut-
off, you can either slide the On/Off switch 2 to position
" " first and then switch the measuring tool back on, or
press either button 5 or button 6.
Deactivating the Automatic Shut-off:
– To deactivate automatic shut-off, hold down button 5 for at
least 3 s with the measuring tool switched on. If automatic
shut-off is deactivated, the laser lines will flash briefly as
confirmation.
Note: If the operating temperature exceeds 45°C, automatic
shut-off can no longer be deactivated.
Activating the Automatic Shut-off:
– To activate the automatic shut-off, switch the measuring
tool off and then on again.
Operation Modes (see figures A – C)
The measuring tool has three operating modes, between
which you can switch at any time:
– Horizontal operation "–": generates a horizontal laser line,
– Vertical operation "l": generates a vertical laser line,
– Cross line operation "–" and "l": generates a horizontal
and a vertical laser line.
Once the measuring tool has been switched on, it is in cross-
line operation. To change the operating mode, switch the hor-
izontal or vertical laser line using button 5 or 6.
All three operating modes can be selected either with or with-
out automatic levelling.
