If the tolerance level was exceeded in the horizontal check,
the laser can be readjusted as follows. In each case the critical
element is the distance that results from the measurement
points taken from opposing positions, i.e. points 1+3 or 2+4.
Example: The distance between points 1 + 3 is greater than
the tolerance of ± 0.1 mm/m. Accordingly, the laser must be
readjusted in this axis.
When performing readjustments, ensure that the batteries
are fully charged.
Position the laser with this axis (the x-axis) towards the wall.
Switch the laser off. To enter calibration mode, first hold
down button (4) (> 5 seconds). Now, still holding button 4,
press the on/off button (3). Next, release button (4) and then
release button (3). The blue (8) and green (9) LEDs flash
rapidly. The laser levels itself and begins to rotate. The white
LED (5) TILT flashes rapidly.
Use the receiver to check the height. The laser is correctly
adjusted when the laser point is situated exactly halfway
between the points 2 and 4. Activate Shift (button 17).
Now hold down button (21) and simultaneously rotate the
remote control unit to move the laser line up or down until
it is in exactly the central position. Each time button (21) is
pressed, the height is altered by 1 unit.
Now rotate the laser through 90° so that the y-axis points to
the wall. If the centre of the laser line does not match the
centre point drawn from the x-axis calibration, the y-axis
should now also be calibrated.
Adjust the height of the laser line again using buttons (17)
and (22) of the remote control unit until the line is again
exactly at the height of the central mark of the x-axis.
Storing the calibration
The laser has now been recalibrated. Pressing button (4)
causes the settings to be stored. To exit calibration without
storing the settings, press button (3) on the laser unit to
exit calibration mode without saving. The old settings are
retained unchanged.
