to improve detection of the laser beam (41). When working
with the laser receiver, select rotational operation with the
highest rotational speed.
Working outdoors (see figure E)
The laser receiver (41) should always be used when working
outdoors.
When working on unstable ground, mount the measuring
tool on the tripod (43). Always work with the shock-warning
function activated in order to avoid faulty measurements in
case of ground movements or shocks to the measuring tool.
Setting up formwork (see figure I)
Mount the measuring tool in the horizontal position on a
tripod (43) and set up the tripod outside the formwork area.
Select rotational operation.
Secure the laser receiver (41) to a measuring rod (42) with
the holder. Position the measuring rod on a reference point
for the formwork.
Align the height of the laser receiver on the measuring rod so
that the variable laser beam (8) of the measuring tool is in-
dicated as "centred" (see operating instructions for the laser
receiver).
Then position the measuring rod with the laser receiver, one
after the other, at different test locations on the formwork.

Overview of status indicators

Measuring tool Function
Green Red
◌ Horizontal position: X- or Y-axis levelling process
Vertical position: X-axis levelling process
◌ Sleep mode activated
● Horizontal position: Both axes are levelled.
Vertical position: X-axis is levelled.
◌ Automatic shut-down due to error message (e.g. empty rechargeable/non-rechargeable battery,
operating temperature exceeded)
◌ CenterFind mode or CenterLock mode started (see operating instructions for the laser re-
ceiver)
Position of the measuring tool changed without switching on/off
◌
◌ Self-levelling not possible, end of the self-levelling range
◌ Shock-warning function actuated
Calibration of the measuring tool is started.
◌
● Horizontal position: At least one axis is tilted or is in manual operating mode.
Vertical position: X-axis is tilted or in manual operating mode.
● lighting up continuously

Make sure that the laser receiver remains in the same posi-
tion on the measuring rod.
Correct the height of the formwork until the laser beam is in-
dicated as "centred" at all test locations.
Checking slopes (see figure J)
Mount the measuring tool in the horizontal position on a
tripod (43). Select rotational operation.
Set up the tripod with the measuring tool so that the X-axis is
aligned with the slope that is to be checked.
Set the target slope as the slope for the X-axis (see "Slope
operation in the horizontal position", page 45).
Secure the laser receiver (41) to a measuring rod (42) with
the holder. Place the measuring rod at the base of the slope
surface.
Align the height of the laser receiver on the measuring rod so
that the variable laser beam (8) of the measuring tool is in-
dicated as "centred" (see operating instructions for the laser
receiver).
Then position the measuring rod with the laser receiver, one
after the other, at different test locations on the slope sur-
face. Make sure that the laser receiver remains in the same
position on the measuring rod.
If the slope of the plane is correct, the laser beam will be in-
dicated as "centred" at all test locations.
