DM5: Shooting Issue

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

    • Operating Pressure: Verify your HPR is supplying enough air to cycle your marker. Adjust if necessary. Turning the adjustment screw on the HPR clockwise will Decrease pressure to your marker while turning it counterclockwise will Increase pressure. When increasing pressure, do it 1/8th of a turn at a time. 

    • Eyes: Check the eyes on your marker and make sure they are clean and functional

    • On/Off: Verify the on/off valve is turned on (dimples will be facing left and right)

    • Bolt Stick: Remove the Fuse bolt and lube all o-rings with Dye Slick lube

    • Hold down the trigger for one second and your gun should fire. If it still does not fire, check/change the following:

      • Dwell: Check your dwell and try resetting back to the factory default setting of 18ms

      • Microswitch: Remove the right grip and verify the trigger is making contact with and engaging the microswitch.

      • Board: Verify all connectors (eyes and solenoid) are properly connected to the board and that there are no pinched or broken wires.

Marker Fires with low first shot:
  • Battery: Start with a new battery as an old one can cause issues with firing your marker.

  • Dwell: Dwell is set to low. Check your dwell and try resetting back to the factory default setting of 18ms

  • Bolt: Remove the Fuse bolt and lube all o-rings with Dye Slick lube

  • HPR: Verify that your High Pressure Regulator is supplying enough air pressure to your marker. If you’re unsure, degas your marker and turn the adjustment screw in (clockwise) until you feel some resistance. Now turn it to the stock setting of 3 1/2 turns out/counter-clockwise

  • LPR: Verify that your Low Pressure Regulator is set correctly. If you’re unsure, degas your marker and turn the adjustment screw in (clockwise) until you feel some resistance. Now turn it to the stock setting of 5 turns out/counter-clockwise

  • Maintenance: If the above does not solve your problem, disassemble both regulators and perform maintenance on them. This means disassemble them, wipe off any dirt and lube, inspect all o-rings for damage and replace them if needed. Then lube all o-rings with Dye Slick lube (or Dow33 based lube) and reassemble. Reference the Maintenance page for details

Marker Breaking Paint:
  • Eyes: Check the eyes and make sure they are on and functional. With the eyes on, sticking your finger into the feedneck should cause the light to change from a solid red light to a solid green. If not, make sure the eyes are clean and not blocked by dirt or old paint.

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

  • Breech: Inspect the breech to confirm there isn't any debris 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. Check out the video below on getting a good paint to barrel match.
