Guide :Air Tools & Compressors : Makita
Makita MAC2200 runs fine (with new Manifold Switch and repaired power cord) but there is an air leak under the new manifold switch that seems to be a feature of the switch. When set to automatic, the compressor runs to pressure of about 115 to 125 pounds, motor shuts down. Then switch the selector to the off position, the compressor bleeds off air until the air pressure reaches about 60 lbs on the gauge then stops bleeding air. When left in automatic the compressor cycles about every 20 seconds while the "air leak" is constant.
