8.1 General Operating Instructions
All instructions for using the unit, whether in verbal or written form, are based on our own
experience and experimentation and can only be regarded as guidelines.
Use heat-resistant gloves or holding tools for the parts to be cleaned.
If the unit is not used for a longer period of time, the mains plug should be pulled
out.
The filter inserts should be changed at suitable intervals in order to achieve
optimal suction performance.
Since the capacity of the collecting tray is limited, depending on the intensity of
work, you should let the collected water run off via the ball valve (drain).
