DM6: Leaking from Back

If your marker is leaking from the rear, check the items below. Reference the manual as needed.​

ID the Source:
  • Start by trying to verify where the leak is coming from, the bolt or LPR. Place your finger over the rear bolt hole. If the leak stops, or you feel air pressure start to build up, replace the o-rings in the Fuse Bolt section. Otherwise, replace the LPR o-rings shown below.

Fuse Bolt:
  • If it is, use a 1/4” allen key to remove the fuse bolt and replace the bolt Stem o-rings and the 2 large o-rings on the rear bolt cap (aka the outer sleeve). 

    • #3 & 4 - Bolt Stem: 009 (x2)

    • #8 - Outer Sleeve: 020 (Outer Sleeve - Red section)

Fuse Bolt - Exploded View:
  • Remove the LPR and replace the 3 body o-rings. While disassembled, inspect the reg seat (small black plug within the adjustment screw) for damage and replace if needed. Reference the exploded view & maintenance video below if needed.

    • #5 - LPR Body: 015
