Assembly
Inserting/Replacing the Batteries
Alkali-manganese batteries are recommended for the meas-
uring tool.
To open the battery lid 3, press on the latch 2and remove the
battery lid. Insert the batteries. When inserting, pay attention
to the correct polarity according to the representation on the
inside of the battery compartment.
If the battery warning 15 flashes, the batteries have to be
replaced.
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 extended
periods, the batteries can corrode and self-discharge.
Using the Rotating Platform (see figure A)
Place the measuring tool on the tool mount of the rotating
platform 12 so that the locking grooves 13 of the rotating
platform fit between the corresponding grooves 6on the bot-
tom of the measuring tool. Turn the measuring tool clockwise
to lock it on the rotating platform.
Extend the legs of the rotating platform using the height ad-
justment screws 10. Roughly align the rotating platform using
the vial 8.
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
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 7to
the “On”position (for working without automatic levelling)
or to the “On”position (for working with automatic level-
ling). The power indicator 15 lights up and the measuring tool
immediately sends a horizontal laser line out of the front exit
opening 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 7to
the “Off” position. The power indicator 15 goes out. The pen-
dulum unit is locked when the tool is switched off.
When exceeding the maximum permitted operating tempera-
ture of 45 °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.
Deactivating the Automatic Shut-off
The measuring tool automatically switches itself off after
30 minutes of operation. To deactivate the automatic shut-
off, hold down either the vertical mode button 16 or the hori-
zontal mode button 17 for 3 seconds when switching on the
measuring tool. The laser lines will flash briefly after 3 sec-
onds if the automatic shut-off is deactivated.
Do not leave the switched-on measuring tool unattend-
ed and switch the measuring tool off after use. Other
persons could be blinded by the laser beam.
To activate the automatic shut-off, switch the measuring tool
off and on again (without holding down a button).
Operation Modes (see figures B–D)
The horizontal and vertical modes can be switched on and off
independently of each other. All operation modes can be used
both with and without automatic levelling.
