Bostitch CAP1512-OF leaks when pressure reduced with regulator
(Mechanicsburg OH USA)
I have a Bostitch CAP1512-OF that had been working fine.
Now, it leaks when pressure regulator is turned counter-clockwise to reduce the outlet pressure.
So now the compressor continuously cycles on as the pressure continuously drops due to the leakage.
I can hear that the leakage is directly under the regulator knob but I don't know how the knob is attached and I don't want to break it.
Can you tell me how to remove the knob and once removed will I be able to make repairs?
