When the procedure has been carried out carefully,
the horizontal distance between the two points (B)
and (C) marked at a height of 10 meters should be
less than 1 mm (at 10 m).

tool to Hilti Service for calibration.
Possible cause
Inclination angle too high
The tool is not correctly
positioned – is already too
steeply inclined.
The rotating laser has
been subjected to shock
– accuracy can no longer
be guaranteed.
The receiver has received
no laser beam for more
than 2 minutes.
The receiver's battery is
almost empty.
The rotating laser's bat-
tery is almost empty.
The tripod's battery is al-
most empty.
The receiver could find
no laser beam within 2
minutes.
The receiver is outside the
Auto E-targeting range.
Autoalignment is not pos-
sible while certain menu
items are being executed.
Remedy
Reposition the tool so
that the inclination value
you have entered can be
achieved.
The tool must be reposi-
tioned in order to bring it
within the leveling range.
Restart the system and
take a reference measure-
ment before continuing
your work.
The tool must be restar-
ted and alignment of the
vertical laser beam then
carried out again.
Charge the battery soon.
Charge the battery soon.
Charge the battery soon.
The process must be re-
