Why does my Duratech Chipper make poor quality chips or not feed properly?
- A
  Adrian BairdAug 16, 2025
  Your Duratech Chipper might be producing poor quality chips or not feeding properly due to several reasons: * The knives may have lost their edge; file, grind, or replace them. * The knife anvil may be worn or need adjustment; rotate, repair, or replace it. * The knives may be at the wrong angle; use DuraTech knives and sharpen them to a 30-degree angle. * There may not be sufficient feedwheel down pressure; increase the spring tension. * The material being chipped may be small, dry, or rotting, which does not produce good quality chips.

What causes the Duratech Chipper knife to hit the anvil?
- S
  Sara AyersSep 1, 2025
  The chipper knife of your Duratech Chipper might be hitting the anvil because: * The anvil is not set properly; follow the anvil adjustment procedure. * The shaft is misaligned; the disc should have the same clearance side to side, so adjust the pillow block bearing. * The disc is not properly set on the shaft; the disc should have a minimum of 11/16” clearance to the housing on the feed side, so slide the disc on the shaft.

  There are several reasons why the feedwheel on your Duratech Chipper might be turning slowly or not at all: * The relief valve may be stuck open, in which case you should clean or replace it. * The hydraulic motor or pump may be worn and need replacement. * There might be a pinched hydraulic or damaged hydraulic hose that needs replacing. * The feedwheel valve might be worn and leaking internally, requiring replacement. * The hydraulic oil level may be low, so fill it to at least 7/8 full. * The oil screen may be plugged, so replace it. * There could be binding due to a worn bearing, which requires repair. * The hydraulic oil might be cold, but it should warm up while running. * The speed sensor could be out of adjustment, not working, or the program set points could be ...
