SOURCE: lack of pressure
the pressure switch needs adjusting - need service book for that one - but I do not think the pressure switch is servicable- I think you have to have switch replaced at service centre.good luck

SOURCE: air compressor not filling tank
Most compressors with the problem that you are having suffer from leaking valves. As in a gasoline engine, leaking valves will lower efficiency. Valves in a compressor are in the form of reeds that seal against valve plate. Leaking reed valves or gaskets will increase the discharge air temperture. Inspect these parts with a magnifying lense. Look for evidense of wear or leaks. Also look for signs of air leaking from one cylinder to the other thru gaskets. Replace valve plate as necessary. Simple test, as your compressor is filling, check the intake for strong suction; as it neers the 92 psi mark suction will probably deminish if you have leaking valves. If suction remains strong at 92psi then you have a leak at the discharge side. Check with soapy water on all parts. Good luck
