Extraction system
To ensure proper fume extraction and vacuum in the cutting area, the extraction hoses need
free of dust and debris.
1.
Remove the vacuum hose from the extraction system (extraction fan, BOFA, or own system).
Illustration purely indicative
2.
Visually inspect the inside of the fan and extraction hose. Remove any debris and/or large
pieces of fabric.
3.
Refit the extraction pipe.
NOTE
: If the vacuum fails and the pump is spinning, there is a blockage in
the system. If there is a strong vacuum (but no airflow) between the pump
and the machine, the extraction pipe between the pump and the outside
world/factory vent network is blocked. If there is a loss of vacuum in the
chamber, there’s a blockage between the machine and the pump.
