ü To assemble the nozzle plate:
ü Both removing tools are mounted on the nozzle plate and locked.
ü The top edge of the pressure chamber is completely covered with solder and
free from oxides and solder dross.
ü The bayonet catches were aligned in such a way that the slots of the screws
run parallel to the edges of the nozzle plate.
a) Risk of accident! Check the locks for tightness again!
b) Lift the nozzle plate holding it with both hands by the upper toggles (A).
ð Risk of accident! Always hold bolted removing tools by the upper toggle
(A)!
c) Place the nozzle plate very slowly on the solder surface and position it carefully
using the coding keys (X).
