e) Sequentially move the screws of the bayonet locks with appropriate tools. In
doing so, slightly press the nozzle plate down.
ð In this way, the nozzle plate is fully lowered onto the pressure chamber.
f) Turn the rotary switch (D) on the control panel to the right.
ð In this way, the solder wave is enabled. Do not run the pump without ni-
trogen gassing for an unnecessarily long time. Otherwise, a lot of dross is
produced unnecessarily.
g) Wait about 10 minutes for the nozzle plate to heat up and the solder to reach
its target temperature again.
h) Remove any extraction tools.
i) Secure the nozzle plate with the socket spanner according to the diagram
shown.
j) Start by fixing the nozzle plate always at the zero point (C) and proceed accord-
ing to the illustrated numbering.
k) Clean all inlet bores with a round brush.
l) Solder wave height visual inspection:
ð Nozzles must be uniformly filled with solder and wave height be the same
for each nozzle.
ð The process has now been completed.

cleaning
This kind of maintenance work must be performed while the solder is liquid! There-
fore, the following safety instructions must be strictly followed:
DANGER
Severe or fatal injury from hot machine!
The entire machine is hot during operation and contains liquid metal!
a) Service on the hot machine may only be carried out by specially trained staff,
qualified for this type of work! For these types of work, a company internal oper-
ating procedure for protective clothing is to be issued!
b) You should always take into account the possibility for metal to spray out!
c) Special care is required when refilling the pot and working on the pot!
NOTE
Use suitable protective equipment!
When performing any work on a hot pot, protective clothing must be worn:
a) Safety shoes
b) Face protection
c) Heat resistant gloves
d) Heat resistant apron.
CAUTION
Risk of material damage!
All the parts of the soldering module coming into contact with liquid solder are
coated.
a) These parts may only be cleaned with a suitable brush.
b) Use a wooden scraper for residual solder which is hard to remove.
WARNING
Death or severe injuries are possible with rolled out soldering module!
ü If the soldering module stands on the solder pot trestle while it is hot:
a) Shut off the work area with a red and white safety chain and a warning sign.
b) Remove possible tripping areas!
