Switching Off the Automatic Levelling
Press the manual button 9 to switch off the automatic
levelling and operate the tool in any inclined positi-
on (see Projecting Inclines). When the automatic le-
velling is switched off, the indicator 10 flashes once
per second.
Press the manual button 3 again to return to auto-
matic self-levelling operation.
Single-axis Inclination Operation
X
Y
Y-axis inclination mode
Press arrow button 8 and within 1 second also press
manual button 9 to activate the manual inclination
mode of the Y-axis.
Simultaneous flashing of the green and red
LED 3/ 10 once per second signals the manual
Y-axis inclination mode.
Incline the Y-axis using the Up
tons on the remote control; the X-axis remains le-
velled (e.g. when installing inclined drop ceilings or
driveways).
X-axis inclination mode
Press arrow button 20 and within 1 second also
press manual button 9 to activate the manual incli-
nation mode of the X-axis.
Simultaneous flashing of the green and red
LED 3/ 10 every 3 seconds signals the manual
X-axis inclination mode.
Incline the X-axis using the right
button of the remote control, while the Y-axis re-
mains levelled.
Press the manual button 3 again to return to auto-
matic self-levelling operation.
Levelling Accuracy
Influences on the Accuracy
The largest influence is exerted by the ambient tem-
perature. Especially temperature differences occur-
ring from the ground upwards can deflect the laser
beam.
From approx. 20 m on, the deviations are crucial
and can easily double or quadruple at 100 m.

Since the temperature gradient near the floor is the
greatest, a tripod should always be used when
working at distances over 20 m. In addition, the
unit should always be set up in the middle of the
working area.
Accuracy Check of the Unit
X- and Y-axis (see figure H)
In addition to external influences, specific unit influ-
ences can also lead to deviations. Therefore, check
the accuracy of the unit each time before beginning
work.
For this purpose, a unobstructed measuring path of
20 m on firm ground between two walls A and B is
necessary. A transit measurement in the horizontal
position over both X and Y axes (each positive and
negative) must be performed (four complete meas-
urement procedures).
Place the unit in the horizontal position on a firm,
level base or on a tripod (accessory) near the wall A
and switch on.

Repeat the measuring process for the other axis. For
this, turn the tool by 90° each time to begin the
measuring process.
For the measured distance of 2 x 20 m = 40 m, a
deviation of ±4 mm is acceptable. Therefore, the
highest and the lowest marks may be 8 mm apart.
When the maximum deviation is exceeded in the
course of an accuracy check, the laser must be sent
to a Würth after-sales service agent.
Z-axis
To determine measuring inaccuracies of the Z-axis,
the vertical calibration should be checked from time
to time.
After the levelling, aim the laser beam in point
operation at the near wall A. Mark the middle
point of the laser beam on the wall (I).
Turn the unit by 180°, let it level and mark the
middle point of the laser beam on the distant
wall B (II).
wall B, switch on and allow to level.
Adjust the unit in height (with the aid of the tripod
or by placing an object underneath) so that the
middle point of the laser beam is exactly at the
previously marked point II on the wall B.
Turn the unit by 180° without changing the
height, allow to level and mark the middle point
of the laser beam on the wall A (III).
and III on the wall A gives the actual unit devia-
tion for the measured axis.
