Vice/Protege: Issues Firing

Marker will not fire or has a problem firing. Check the items below. Reference the manual as needed.

Issue:
Aired Up with no Leaks & Won't Fire:
  • Battery: Make sure you start with a brand new battery in your gun as an old one will cause issues. 

  • ASA: Check that the pin on your ASA is making contact with your air tank and air is pressurizing your gun.

  • Vertical Adaptor (HPR): If you recently serviced your High Pressure Regulator, disassemble and verify it was properly re-assembled, including the spring stack washers. These should be stacked as follows:   )()()()(  

  • Connectors: Check that all connectors going to the circuit board are properly seated (battery harness, eyes, solenoid and on/off button).

  • Micro-Switch: Turn on your gun with the eyes off, pull the trigger and confirm that the solenoid clicks. If it doesn't, check your micro switch. If the micro-switch is ok, check the solenoid as indicated below.

  • Pressures: Using a pressure tester, verify your LPR is set to 70-75psi and your HPR is sitting at 170psi. Adjust if necessary.

  • Dwell: Check your dwell and try resetting back to the factory default setting (6ms)

  • Solenoid: Remove your trigger frame and check that the hose going into the solenoid isn't being pinched. Next, press the red button on the solenoid to cycle your marker. If it doesn't cycle, your solenoid might be bad. If you suspect there is debris inside your solenoid, reference the Marker Leaking from Frame page for details on servicing your Humphrey solenoid.

  • Dwell: Check your dwell and try resetting back to the factory default setting (6ms)

  • Pressures: Using a pressure tester, verify your LPR is set to 70-75psi and your HPR is sitting at 170psi. Adjust if necessary. 

Marker Fires with low first shot:
Velocity/Regulator Pressure Issue:
  • Inconsistent Velocity

    • Battery: Make sure you start with a brand new battery in your gun as an old one will cause issues. 

    • Pressures: Using a pressure tester, verify your LPR is set to 70-75psi and your HPR is sitting at 170psi. Adjust if necessary. 

    • Dwell: Check your dwell and try resetting back to the factory default setting (6ms or 8ms)

    • Ram: Remove the ram and inspect the o-rings for damage and replace if needed. Remove any dirt or lube from the ram and apply a small amount of Dow55 to the o-rings.

      • Ram cap o-ring: 1mm x 12mm (Dura 70)

      • Front ram o-ring: 006 (Dura 70)

      • Rear ram o-ring: 011 (Dura 70)

    • HPR: Disassemble your reg and check the piston o-ring for damage and replace if needed. 

      • Piston o-ring: 016

  • LPR Spikes:

    • Remove your LPR and disassemble in order to clean and inspect your o-rings. Replace any damaged or nicked o-rings and lube with Dow55. Reference page 11 of the manual for step-by-step instructions for removing.

      • Tip for Removing the LPR Piston (Credit goes to Mike from Techpb): Take a standard nail, put a very small drop of superglue on the head of the nail then press the nail against the top of the piston. Set the LPR down so it's upright and let the superglue dry for 5 mins. After it's dry, pull out the piston and gently break off the nail and remove any dried superglue on the piston.

Marker Breaking Paint:
  • Pressures: Using a pressure tester, verify your LPR is set to 70-75psi and your HPR is sitting at 170psi. Adjust if necessary. 

  • Eyes: Check the eyes and make sure they are on and functional.

  • Detents: Check your detents for excessive wear/damage. Replace if needed.

  • Breach: Inspect the breach to confirm there isn't any debris inside the breach that would cause you to break paint.

  • Paint: Make sure you're using good quality paintballs and that you have a good paint to barrel match.
