8.11.9.5 Removing the cooled DIP solder pot from the machine
NOTE
Let the solder cool off before replacing the DIP solder pot
Let the solder cool off before replacing the DIP solder pot. To do so, it must be solidi-
fied. A safety switch prevents the extraction of the DIP solder pot in case the solder is
still too fluid or too hot.
NOTE
To move the DIP solder pot out of the service position, acknowledge the service
message
To be able to move the DIP solder pot out of the service position, acknowledge the
corresponding service message. Afterwards, you will have five minutes to move the
DIP solder pot out of the service position. During this time, a corresponding notice will
be displayed. If the DIP solder pot has not been moved after this time, a timeout mes-
sage appears. After acknowledging the timeout message, you will have another five
minutes to move the DIP solder pot out of the service position.
ü To remove the cooled solder pot from the machine:
ü You have donned the required protective clothing.
ü The DIP solder pot is in the [Service] position.
ü The bar spacer and the height of the replacement rack have been adjusted ac-
cording to the machine configuration.
ü The traction aid is mounted on the machine.
ü The DIP solder pot has cooled off.
a) Open the doors and hoods in the area of the soldering module.
b) Open the cover of the gassing hood.
c) Lift the empty replacement rack with the lifting cart.

f) Position the replacement rack in such a way that the forklift forks (5) of the lift-
ing cart slide along the traction aid (6) both on the right and on the left.
ð The second worker should give you instructions on how to position the re-
placement rack, since the traction aid is barely visible from the position of
the lifting cart driver.
g) Push the replacement rack towards the machine until the bar spacer hits the
machine frame.
ð The second worker should visually check whether the replacement rack
has been brought completely to the machine.
h) Turn the bar of the lifting cart by 90° (7), so that it cannot roll away.
