The opening of the deflection unit must be done in a dust-protected environment. If dust deposits on
the optics, it burns in during operation by the laser radiation so that the optics will be destroyed.
1. Remove the four retaining screws (1) of the protective window (3).
2. Carefully lift the retaining frame (2) off the protective window.
3. Remove the protective window.
4. Check the compensating ring (5) for correct fitting in the output plate (4).
Install the new protective window in reverse order. Make sure that the compensation/sealing ring(s)
are in the correct position. Be careful not to touch the optically relevant surfaces of the protective
window and remove dust particles on the optical surfaces.
Tighten the four screws (1) with a torque of 0.8 Nm. First lightly tighten all four screws and then
tighten them crosswise with a torque of 0.8 Nm.
