DM12: Velocity Issue

Marker has inconsistent velocity or you're not able to adjust the pressure. Check the items below. Reference the manual as needed.

Issue:
Inconsistent Velocity:
  • Battery: Start with a new battery as an old one can cause issues with firing your marker

  • Dwell: Check your dwell and try resetting back to the factory default setting of 18ms. If it's already set at 18ms, try raising the setting a little at a time. Reference page 7 - 10  of the manual for details on changing this 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.

  • 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

    • #5 - Front Wall Internal (Beer Can): 017

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

  • Maintenance: If the above does not solve your problem, disassemble both regulators and perform maintenance on them. This means disassembling, wiping off any dirt and lube, inspect all o-rings for damage and replace if needed. Pay special attention to the piston o-rings (small & large) on both regs & the reg seat in each. Lube all o-rings with Dye Slick lube (or Dow33 based lube) before reassembling. Check out the Maintenance page if needed.
