Maintenance work to be performed weekly
9.3.1 Cleaning the control of the pick-and-place nozzle
The control of the pick-and-place nozzle needs to be cleaned at least once a week.
With intensive use of the HR 600/2 unit, daily.
The pick-and-place nozzle is exposed to flux smoke. Depending on the intensity of
smoke exposure, the pick-and-place nozzle requires regular cleaning. Use a smoke
evacuator to reduce smoke build-up.
CAUTION
Risk of burning due to heated machine parts and PCB!
All heated machine parts as well as the surrounding housing parts and product sup-
port frame, the circuit board and the components become hot even during warm-up
to the process temperature [Tinit]!
Parts are particularly hot during the soldering process! After the soldering process,
wait until the device and the PCB have cooled down and reached non-hazardous tem-
peratures!
ü To clean the control:
a) Activate the tab [Placement] in the menu bar.
