Fig.150: Disassemble the nozzle plate. Always hold bolted removing tools by the upper toggle (A)!
ü To disassemble the nozzle plate:
a) Remove any solder from the baffle frame (1). To do so, open the drain screw
(2) with a socket spanner (3).
b) Unlock all bayonet catches (5) with the socket spanner. Align the bayonet
catches so that the slots of the bolts (5) are parallel to the edges (6) of the
nozzle plate.
c) If necessary, convey any soiling (oxides, dross) into the solder bath using a silic-
one brush (4).
ð As soon as the solder has run out of the baffle frame:
d) Close the drain screw (2) and remove the socket spanner (3).
e) Place the two removing tools (8) on the nozzle plate and lock them.

Fig.151: Clean the nozzle plate. In this figure, only one nozzle (2) is present. Your nozzle plate may have several nozzles of different
shapes.
ü To clean the nozzle plate:
ü Please note: The parts coming into contact with solder can be cleaned more
easily as long as they are still hot!
a) Thoroughly clean all bayonet catches (3) and disc springs (4).
ð Bayonet catches and disc springs must be easy to move.
b) Clean the underside (5) of the nozzle plate.
c) Carefully clean sealing surfaces (6)!
ð In the case of soiled nozzles (2).
d) Clean all nozzles (2) inside and outside.
e) Visually inspect the top of the nozzle plate.
