11.7.5 Replacing the Entire Dispensing Needle with Centering Nozzle
If the centering nozzle is defective, it can be replaced on its own. The dispensing needle is a complete assem-
bly.
It may be necessary to replace the entire dispensing needle if it or the hose is clogged by the formation of
crystals in the flux and thus has to be replaced. In this case, the entire assembly is replaced.

Loosen the centering nozzle.
Pull the cylinder cover and the dispensing needle away from the cylinder and pull out the entire dispensing
needle from the cylinder.
Disconnect the end of the hose of the dispensing needle from the valve of the metering pump.
Thread the new dispensing needle through the cylinder cover and through the cylinder and into the center-
ing nozzle. The tip of the dispensing needle must protrude approximately 3 mm from the centering nozzle.
Tighten the centering nozzle once more.
Push the cylinder cover onto the cylinder.
Check the distance between the dispensing needle and the PCB. Push the piston down as you do so. The
distance must be approximately 1 mm.
If this distance is not correct, it must be reset.
