Message
"Size reduction failed"
Note: When technical faults occur, please refer to the error messages section.
The size reducer can run either in continuous operation or for a time which can be
adjusted from 10 - 180 sec.
Starting with the main screen, set a process run duration of XXXs
(flashes) with the ◄ or ► key.
When put into operation for the first time, the device's default setting is a
process run duration of 60 sec.
Use the ▲ or ▼ keys to scroll through the list of the size reduction times,
ending with continuous operation.
Tests have shown that a process run duration of 30 - 60 sec. is sufficient
for the size reduction of most samples.
Starting with the main screen, use the ◄ or ► keys to set a motor
speed (flashes).
Use the ▼ or ▲ keys to scroll through the list of speeds (normal, slow, fast).
When put into operation for the first time, the default setting is "normal"
speed.

Cause and possible remedy
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.
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.
