4-16: Replacing the deflection unit
X Fit the elastomeric spring (10) on the new
deflection unit (8).
X Fix the deflection unit (8) to the gantry, with the
two M6 x 10 hexagon socket-head screws (7).
X Align the brake "outside" (5) so that it is
parallel with the braking surface and fix it to the
deflection unit (8) with the two M3 x 8 hexagon
socket-head screws.
X Run the toothed belt (9) around the
synchronizing disk of the deflection unit (8).
