Troubleshooting 

Which medium can I use for the power supply of the engine?

You can safely use high pressure air. Bear in mind the use of CO2 may cause permanent damage to the device, which is not covered by the warranty.

What thread for the power line?

M5 thread 0.8 mm pitch.

Are there IGL lines available for the engine?

Probably not, all engines on the market have inch threads. Our line is robust enough due to the fact that a bolt-on threaded end has been used in it, and there is no need to replace it with IGL, as with other engines.

Is the PULSAR D engine closed-bolt or open-bolt?

The PULSAR D is a dual solenoid valve engine and operates in a closed-bolt sytem, and optionally in an open-bolt system.

How much maximum pressure can I set with the PULSAR D engine

The engine is designed to operate with a maximum pressure of 140 PSI.

I have a problem with low FPS

The first thing to check is:

• the hop-up bucking

• the hop-up chamber

• the HPA engine settings in the GCS application
  

...

What regulators are compatible with PULSAR D?

PolarStar MRS

Redline SFR

Wolverine STORM

What to do if there is no nozzle cycle?

First, check if the wires are connected in the correct order to the solenoid valves. If the replica is firing correctly but the TP NM error appears in the application, it may be because shots were taken without connected pressure. In such a case, you can either ignore the error or clear it by cleaning the DTC.

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

There is no nozzle cycle

• If the replica is firing correctly but the TP NM error appears in the GCS application, it may be because shots were taken without connected pressure.

1. In such a case, you can either ignore the error or delete it by clearing the DTC.

2. If the problem persists, first check if the wires are connected in the correct order to the solenoid valves.

3. 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.

Unstable FPS

• The tappet plate spring is broken

Replace the 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

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:

1. .g. Retro Arms

2. Reassemble the gearbox and the replica

• Excessively low operating pressure

In some cases, (e.g. because of low outside temperature or replacing the tappet plate spring with a harder one), 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. Follow these steps:

1. increase the pressure on the regulator until the BBs are properly fed

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

Nozzle does not return to the front position when it is depressed
