Default Qb78 deluxe PCP

Hello to all,
I have a question regarding my qb78. I believe the the valve is locked. I have a bulk fill adapter and pressurized to about 1400 psi and the hammer is hitting with pull of trigger just not releasing air. Any ideas of how to depressurize? Itís holding pressure really good. Thanks for any ideas.

MAC1 Airguns in Signal Hill should be able to help you out. Tim actually designed the QB78.
