See Auger Brazing section in this manual Elbows wear out. Auger is stretched too tight; horizontal L.H. turn; auger has been running dry. Lengthen auger; Install an Extension Hopper. Excessive auger vibration and noise. System has been operated too often without feed (auger has scored the auger tubes). Replace damaged auger tubes; be sure auger has proper amount of stretch. Tubes inadequately supported. Support the tubes every 5’ (1.5 m) or closer. Horizontal L.H. turn. No outlet drops on or just before an elbow; lengthen the auger; install an Extension Hopper ahead of elbows. Fill system short cycles.
