8.1 Check the rework system on a weekly basis for any dirt or damages.
Check the following machine parts on a weekly basis for any dirt or damages. If you
spot any dirt, remove it as indicated. During cleaning never scrub the machine and
never work with hard or sharp-edged objects!
Before performing any cleaning or maintenance operation, turn off the rework sys-
tem from the main switch!
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!
