11.9.6 Replacing the complete dispensing needle and centering nozzle
If the centering nozzle is defective, it can be replaced on its own. The dispensing needle is a com-
plete module, however. It may be necessary to change the complete dispensing needle if it or the
hose becomes clogged due to crystallization of the flux. In this case, the complete module must
be replaced. 11
