How to troubleshoot starting issues with Ammann APH 5020 Vibratory rammers & tampers?
- J
  Julie LawrenceAug 12, 2025
  If the Ammann Vibratory rammer & tamper engine doesn't start, several factors could be at play. First, ensure the speed control lever is in the 'START' position. If it is, check the fuel level; a dry tank or a blocked fuel filter can prevent fuel from reaching the injection pump. Also, verify the engine oil level, as low oil pressure can cause starting issues. If these steps don't resolve the problem, and low compression is suspected, contact a HATZ-service station.

Why is the Ammann Vibratory rammers & tampers engine performance reduced?

  Michelle WhiteAug 19, 2025
  Reduced engine performance in your Ammann Vibratory rammer & tamper can stem from several causes. Start by checking the fuel supply; a dry tank or blocked fuel filter can restrict fuel flow. Ensure the tank venting is adequate. Inspect pipe unions for leaks. Also, a blocked air cleaner can hinder performance, so remove any dirt. Other potential issues include incorrect valve clearance (adjust valve clearance), too much oil in the engine (drain off engine oil down to upper mark on dipstick), or too much oil in the exciter (check exciter oil level). If none of these resolves the issue, there might be a default in the hydraulic system, so contact an Ammann-service station.

  If your Ammann Vibratory rammer & tamper engine stops unexpectedly, it could be due to a few reasons. Check the fuel supply; a dry tank or a blocked fuel filter can interrupt the fuel flow. Also, verify the engine oil level, as low oil pressure can cause the engine to stop. If the issue persists, there might be mechanical defects, so contact a HATZ-service station.

Why Ammann Vibratory rammers & tampers does not move forward when the engine is running?
- J
  Julie ScottSep 4, 2025
  If the engine of your Ammann Vibratory rammer & tamper runs but the machine doesn't move forward, the centrifugal clutch lining may be worn, requiring replacement of the linings and springs. Additionally, check the exciter oil level, as too much oil can cause this issue. If these steps don't resolve the problem, there might be a default in the hydraulic system, so contact an Ammann-service station.
