testo= """6.2_ KNIFE CHANGE     When the software indicates a knife change (see figure 63), follow these steps:   1. Press the emergency button to turn off the motors.   2. Press the cover lift button on the cutting head (figure 63b).   3. Rotate the plate to access the two screws comfortably that secure the knife to the knife holder.   4. Use a 2.5 mm hex key to remove the 2 screws from the knife holder (fig. 64) by turning counterclock‐ wise.  Figure 63—knife change notice    Figure 63b —buttons that raise and lower the cover  Cutting head cover  opening button   6 —  63      NOTICE  The knife must pass through all its guides. Repeat the insertion process into the guide sleeve if  the knife appears to be forced or is not aligned correctly.  5. Detach the knife from the knife holder (fig. 65) by moving the knife downward.   6. Rotate the plate to a position that makes it easy to remove the knife: place the cutting edge towards  the beam.   7. Pull the knife upwards from the guide sleeve, being careful not to cut yourself (fig. 66). The knife is  sharp!  WARNING   The knife is sharp: exercise extreme caution and avoid touching the sharp edge. It is recom‐ mended to use specialized gloves for maintenance operations.   NOTICE  The knife cannot be secured if inserted the wrong way, as the screw holes would not align. Pay  attention to the insertion direction of the knife: the noncutting edge must face towards the  plate support.   8. Insert the new knife from the top to the bottom, ensuring that you align the guides located inside the  guide sleeve and on the plate support.   9. Position the knife so that the holes on its upper part align with the holes on the knife holder.   10. Tighten the two securing screws using the 2.5 mm hex key.

Lower the cutting head cover by using the dedicated button on the operator panel and release the pre‐ viously pressed emergency button.   12. Start the machine's motors using the appropriate switch on the computer console (see  4.2).   13. Open the VCUT program and navigate to the PARAMETERSKNIFE section. Click on the "NEW KNIFE"  button to restore the values related to the knife size and consumption (figure 67).   NOTICE  Failure to confirm the knife change in the VCUT program can lead to inaccuracies in cutting. The  knife dimensions entered in the VCUT program must always match the actual knife dimensions.
