I have a 2400 and just replaced the dump valve on startup

Customer Question

I have a 2400 and just replaced the dump valve on startup pressure is fine but after about two min the pressure dropped off, after restart pressure was good again but when I released the trigger then squeezed the trigger there was no pressure, tried cycling the trigger a bunch of times with no results. I did not lube the dump valve.

The unloader valve has to let pressure build and then release. I think you know what needs to be done, Remove it again and lube it up so it can shift. Us a light grease or vaseline.
