  1. Have ready the replica in which you will install the PULSAR H engine.

  2. Remove the gearbox shell from the replica.

  3. Remove all components from the gearbox.

  4. Thoroughly clean and degrease the gearbox shell.

  5. Prepare the parts that you will use again when assembling the motor:

    1. trigger together with the spring

    2. selector plate.

  6. Get familiar with the contents of the PULSAR H engine packaging and the contents of the manual.

  7. Prepare the items for installation:

    1. PULSAR H HPA engine

    2. Air hose

    3. TITAN II Bluetooth® V2 gearbox drop-in FCU mosfet HPA

    4. Installation kit.

  8. Install the bottom PCB of TITAN II Bluetooth®. The distance around the bearing should be symmetrical.

  9. Place the wires as shown in the picture. Make sure that the wires do not obstruct the pin hole, the trigger sensor, and will not interfere with the trigger.

  10. Screw the air hose connector into the engine body opposite the valve. You can use a wrench or pliers to tighten it a little more.

  12. In the case of the ASTER II, plug the motor connectors into the cable with the connector for the single-valve HPA engine (polarity does not matter in this case) and then connect it to the valve. Here you will find the full instructions for the ASTER II Bluetooth®: https://help.gatee.eu/space/GHC/3145891841/User+Manual+%25E2%2580%2593+ASTER+II+Bluetooth%25C2%25AE+EXPERT+for+V2+GB+%255BAEG+%2526+HPA%255D

  13. Place the engine in the place of the cylinder so that it is pushed against the front wall of the gearbox.

  14. Install the trigger and the top PCB of TITAN II Bluetooth®. You will find the full TITAN II Bluetooth® manual here: https://help.gatee.eu/space/GHC/2873360445/User+Manual+%25E2%2580%2593+TITAN+II+Bluetooth%25C2%25AE+EXPERT+for+V2+GB+%255BHPA%255D

Note

If you have a stock guide that screws into the spring guide, you will need to unscrew or shorten the spring guide so that it fits behind the engine. To stabilize the guide, we suggest using, for example, a bumper from an AEG cylinder head or enough electrical tape wrapped around the guide to stabilize the guide in the gearbox.

...

  1. Close the gearbox shell and check that it closes evenly (do not tighten the screws). A slight gap before you have tightened it is acceptable.

  2. If everything is in order (pay attention to the wires so as not to pinch them), secure the gearbox with the screws

  3. If you have an adjustable trigger, such as the Nova Trigger, you can now adjust its range of movement. This should be done before calibrating the trigger sensor.

  4. Have the selector plate properly prepared by sticking the sticker from the installation kit labeled Selector Plate Sticker on it. Precision and accurate placement of the sticker on the plate is very important - see photo below:

  5. Install the selector plate and other selector components if any.

  6. Place the shell in the body of the replica.

  7. Install the grip by previously putting the air hose through the hole where the motor gear was previously located.

    image-20240830-074320.png

  8. Remove the adjustment screw from the motor cover.

  9. Then put the air hose through the hole where the screw was and install the cover.

  10. Installing the buffer tube guide

    1. Gently tighten the guide screw so that the spring guide stays in place.

    2. Tighten the screw of the buffer tube guide until you feel resistance.

  11. At the end of the air hose, install the connector in the standard you will be using.

    image-20240830-074532.png

  12. Install the upper part of the replica body including the barrel and chamber.

  13. Connect the battery and perform trigger and selector calibration using the GCS app.

  14. Insert your magazine loaded with the BBs of the weight you’re going to be using.

  15. Carry out FPS measurements using a chronograph.

    1. If the results are stable, proceed with accuracy test - step 30.

    2. If you have encountered FPS spikes or results that are too low, then probably the gearbox has not been installed axially in the lower receiver. Go to point 31.

  16. Aim test - if the previous FPS measurements and now the accuracy test are satisfactory, then your replica is ready. If you have encountered problems at any of the previous stages, proceed to the next point.

...

  1. Have all the listed items ready.

  2. Remove the air hose.

  3. Unscrew the front of the engine.

  4. Remove the nozzle from the engine body.

    Image RemovedPULSAR-H-instrukcja_9.jpgImage Added

  5. Gently unscrew the valve (be careful of the very delicate O-rings on the valve).

    Image RemovedPULSAR-H-instrukcja_10.jpgImage Added

  6. Remove all the o-rings from the engine components except the valve (it is best to use plastic tools for this so as not to damage the aluminum surfaces of the engine - this is not covered by the warranty).

    1. If the o-rings are not damaged, you can reuse them after cleaning them with a paper towel (it is best to avoid washing the o-rings with detergents).

    2. If the o-rings are damaged or show signs of wear, replace them with new ones - included in the kit.

  7. Place the engine components in a dish with petroleum ether (NOTE - does not apply to the valve. Avoid immersing it in cleaning agents).

  8. Using a thicker brush and tweezers, thoroughly clean the engine components.

  9. Wipe the o-ring surfaces gently and remove visible dirt with a dry brush.

  10. Set the washed parts aside on a paper towel to dry completely (you can speed up the process by blowing the parts with compressed air).

  11. Prepare the kit for reassembly.

  12. Reinstall the O-rings (you can gently grease them before installation):

    1. 2 pieces of 7x1 mm in the front of the engine.

    2. 2 pieces of 8x1 mm on the nozzle.

    3. 1 piece 20x1 mm for the engine body.

  13. Prepare all parts with the o-rings installed, as well as grease and a smaller brush.

  14. Grease well the two o-rings in the front of the engine (you can remove the excess with a paper towel).

  15. In the rear of the engine body, grease two places:

    1. O-ring and thread.

    2. Then the vertical surfaces of the cylinder where the nozzle moves. Try not to lubricate the bottom of the cylinder. This can have a negative effect on the operation of the engine.

  16. We also lubricate two places in the nozzle:

    1. Both O-rings. As with the engine body, be careful not to leave grease on the flat rear surface of the nozzle.

    2. And the narrowed surface of the nozzle. There may be more grease here.

  17. Place the greased nozzle in the engine body.

  18. Then screw the engine front (excess grease may collect on the nozzle - remove it with a paper towel).

  19. With the flat surface of a brush, gently grease the threads and o-rings of the valve. Avoid getting grease into the moving parts of the valve.

  20. Gently, being careful of the valve's o-rings, screw the valve into the valve socket. It is enough to do this with your bare hand, do not use tools for this.

  21. Screw on the air hose.

  22. The engine is ready to be used again.
