The engine works correctly from about 60-70 PSI. If there is no full nozzle cycle, you can increase the pressure on the regulator and reduce the nozzle cycle time. If this does not help, you can install a tappet plate spring with a smaller force.

How do I know the tappet plate spring is broken?

If you experience any of these, your tappet plate spring is broken:

  • unstable FPS

  • sudden scattering of BBs when previously everything was OK

  • muffled firing sound - significantly different from the regular one

  • no BB feed

  • nozzle does not return to the front position when it is depressed

How do I replace a tappet plate spring?

  1. Disassemble the replica and remove the gearbox

  2. Open the gearbox

  3. Remove the damaged tappet plate spring and make sure that no part of it is left in the gearbox – a part of the spring left behind may cause malfunction of the tappet plate

  4. Install a standard nozzle tappet plate spring from an AEG replica – we suggest using soft springs e.g. Retro Arms

  5. Reassemble the gearbox and the replica

Note

Caution
If the spring you have installed is stronger than the one from the factory, it may be necessary to set a higher operating pressure, which will result in a higher firing rate. You will then need to shorten the Main Valve Time (DP) to achieve lower FPS. Conduct the process according to the following steps:

  • increase the pressure on the regulator until the BBs are properly fed

  • decrease the Main Valve Time (DP) until the desired muzzle velocity is achieved
