2K5: Shooting Issue

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

Issue:
Gun is aired up and will not fire:
  • Shot Counter: With your gun on, pull the trigger and confirm the shot counter on the display is counting. If not, the micro switch is bad.

  • Eyes: Check the eyes on your marker and make sure they are on and functional. An * (asterisk) shown on the bottom left of your display means there is an eye sensor malfunction.

    • Notes: 1) Marker will not fire in Force mode unless there is a ball in the breech. 2) Delay mode will cause the marker to wait 1 second to fire after the trigger is pulled. 3) Dry Fire mode will allow you to fire your marker without the use of the eyes.

  • Dwell: Dwell is set to low. Check your dwell and try resetting back to the factory default setting of 8ms

  • LPR Pressure: Verify that your LPR is set between 70-80psi. Adjust if needed.

  • Pinched hose: Remove your trigger frame, check your hoses and re-position if needed.

  • Solenoid Connector: Remove the trigger frame and verify the electrical connectors are securely attached to your solenoid and to the board.

  • Debris in Solenoid: 

    • With your marker aired up, push the red reset button on your solenoid. If it does not fire, you might have debris lodged inside your solenoid. You can 1) use one of the following guides to service your Humphrey solenoid (at your own risk) or 2) contact Blast for assistance.

  • Dwell: Dwell is set to low. Check your dwell and try resetting back to the factory default setting of 8ms

  • HPR: Using a pressure tester, verify that your High Pressure Regulator is set to 180psi and adjust if needed. If you don't have a pressure tester, but you do have a chronograph, try adjusting the pressure on your HPR and chrono your gun to the desired fps. 

  • Maintenance: If the above does not solve your problem, inspect your rear Ram o-ring and replace if needed then disassemble and maintain both regulators (HPR and LPR). This means, wiping off any dirt and old lube and re-lubing all o-rings with Dow55.

Marker Fires with low first shot:
Marker Fires on Pull & Release:
  • Micro Switch: With your gun on, pull the trigger and confirm the shot counter on the display is counting. If not, the micro switch is bad.

Marker dies off w/ rapid fire:
  • HPA Tank: Check the depth of the pin valve on your air tank to confirm the pin is being depressed enough to pressurize your marker.

  • LPR Pressure: Verify that your LPR is set between 70-80psi. Adjust if needed.

Marker Breaking Paint:
  • Eyes: Check the eyes on your marker and make sure they are on and set to the correct setting (Force Mode=F or Delay=D). An * (asterisk) shown on the bottom left of your display means there is an eye sensor malfunction.

    • Notes: 1) Marker will not fire in Force mode unless there is a ball in the breech. 2) Delay mode will cause the marker to wait 1 second to fire after the trigger is pulled. 3) Dry Fire mode (S) will allow you to fire your marker without the use of the eyes. 

  • Detents: Check your detents for excessive wear or damage and replace if needed.

  • Paint: Check that you have a good paint to barrel match and that you are using quality paintballs.
