I assume turning up the pressure doesn't help. The regulator probably has a torn diaphragm. It will need replaced (i doubt you can get a rebuild kit).

SOURCE: Makita MAC5200 Compressor. Leaks
There are two types of regulators used. One has a rubber diaphram sealed at perimeter with body and a piston type. Most likely you have the piston type. Remove body containing piston/ spring mech. Examine piston lip seal. Lip will face toward body of reg. and must fit snugly into cylinder. Make sure cylinder is smooth and is well lubed.
If seal/piston fits loose remove seal and wrap some teflon tape in groove and re-install lip seal /test for snug fit. Notice small metal actuator extending from center of reg. , if it is circular (about 1/8 dia) then there should be an oring of the same size mated/fit into the piston. If this oring is missing it will leak as you describe. Lastly, there should be a gasket or oring sealing outer shell to body. If you have diaphragm type look for holes, tear or shrink too small. Parts are at www.toolpartsdirect.com or Lowes in the plumbing department good place for orings and silicone lube. Good luck

You could give it a try you don't have anything to loose and you might be able to clean it and thats what it sounds like. But you can redo bolth of the regulators with new ones get rid of the plastic cover and they thread on a pipe that comes out of the air system. You could get two new gauges and a manifold body for 50 dollars at a place that sells auto paint supplys or spray equipment. If the compresser still works good its worth it you just have to do a little retro fitting these parts tend to be vary standard its your call good luck

Testimonial: "Thanks. If I can't get it to work by my attempt at cleaning, I'll certainly follow your advice."
Here is the story. You do not need a receipt but tell them it is the older compressor. They are obligated by law to replace the part since it has been deemed defective unless they want a class action lawsuit in which case they would have to pay triple damages.
