DM12: 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: Start with a new battery as an old one can cause issues with firing the marker.
  • Eyes: Check the eyes on your marker and make sure they are clean and functional.

  • LED: If the LED is red, there is no ball in the breech

  • 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. 

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

  • Wires: Remove your grips and confirm all connectors are firmly seated in the board

  • Trigger: 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

    • Micro-switch: 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. Reference page 8 & 9  of the manual for details on changing this setting

  • Bolt Stick: 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 2 1/2 turns out/counter-clockwise

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

Marker Breaking Paint:
  • Loader: Check the functionality and speed of your loader to make sure it's feeding at a rate that your marker can handle based on the current rate of fire setting

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

  • Eyes: Check the eyes on your marker and make sure they are on and functioning correctly. Also look into the feed neck and verify the eye sensors are not being blocked by paint or debris. 

  • Eye Pipe: Remove your eye pipe and check/test the 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. Check out the video below for details on getting a good paint to barrel match.

  • Bolt: Remove the Fuse bolt and replace any o-rings that appear to be worn or damaged. Pay special attention to the bolt tip and Internal Cylinder (aka beer can) o-rings as they may need to be replaced. Lube all o-rings with Dye Slick lube (or Dow33 based lube) before re-assembling. 

    • #1 - Bolt Tip: 014

    • #4 - Cylinder Internal (Beer Can): 017
