      If the engine of your Ammann Power Tool stops during regular operation, it might be due to an interrupted fuel supply, a dry tank, a blocked fuel filter, or a defective feed pump. Other potential causes include lost oil pressure or mechanical defects. Try adding fuel, renewing the fuel filter, checking the engine oil level, or having the feed pump function checked. If these steps don't resolve the issue, contact an Ammann service station.

      If your Ammann Power Tool engine isn't starting, it could be due to several reasons: no fuel, a dry tank, a blocked fuel filter, a defective feed pump, lost oil pressure, or low compression. First, set the lever to the "START" position and add fuel. If that doesn't work, renew the fuel filter and check the engine oil level. Have the feed pump function checked. If the problem persists, contact an Ammann service station.

      Ashley PorterAug 19, 2025
      If your Ammann Power Tool isn't moving forward even when the engine is running, it could be due to insufficient V-belt tension, a broken V-belt, worn centrifugal clutch lining, too much oil in the exciter, or a fault in the hydraulic system. Try re-tensioning or replacing the V-belt, and replacing the linings and springs. Also, check the exciter oil level. If the issue continues, contact an Ammann service station.

    Why is the performance of my Ammann APR 4920 engine reduced?
    • K
      Kevin FranklinAug 27, 2025
      Reduced engine performance in your Ammann Power Tool can stem from an obstructed fuel supply (dry tank, blocked fuel filter), inadequate tank venting, leaks at pipe unions, a blocked air cleaner, incorrect valve clearance, too much oil in the engine or exciter, or a fault in the hydraulic system. Try adding fuel, renewing the fuel filter, ensuring adequate tank venting, checking threaded pipe unions, and removing dirt from the air cleaner. Also, adjust the valve clearance, drain engine oil to the upper mark on the dipstick, and check the exciter oil level. If problems persist, contact an Ammann service station.
