Performance Chart
Integrated Air Supply
The drill has integrated air supply for flushing (Vane type compressor)
Inadequate air flushing will significantly reduce the drilling performance. If the air
flushing is lower than usual first check the air filter and if that is ok please ask your
HYCON dealer to check for worn out vanes.
The rock drill can be modified for external air. Please contact your HYCON dealer
