    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.

    Why is the feedwheel on my Duratech Chipper turning slowly or not at all?
    • B
      Brenda BarberNov 11, 2025
      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 ...
