Faults during Size Reduction
Fault
Cause and possible remedy
Sample material escapes
Check contents in bag (samples that are too hard,
e.g. shells, can damage the bag). Examine the bag
quality (e.g. for weak seams). If the fault occurs
repeatedly, please ask customer service.
Message
“Size reduction failed”
Take the bag out and check if the sample is not too
large.
If the reason for the message is not apparent, please
read through the “Fault diagnosis” section.
Note: When technical faults occur, please refer to the error messages section.
