important to activate the emergency stop button!
Disassembling the degassing sleeves
Remove the filter housing by loosening the 8 screws [5] and pull the filter housing [1], rubber
gasket [2], filter [3] and filter gasket [4] out wards. Replace the gaskets [2, 4] and the filter
[3], and assemble the filter housing on the extruder cylinder. The screws [5] are to be
tightening equally, and not so tight that rubber gasket is broken.
Notice!
The screws [5] have different lengths. It’s important that the screws are not switched
as they will block and damage the extruder.
