Guide :Air Tools & Compressors : Craftsman
My compressor doesn't build enough pessure.
The pressure guage goes up to about 50 lbs. and doesn't gain any more pressure. The pump continues to run (the motor runs constantly as long as it is turned on). This is just with the compressor turned on to pressurize the tank, with no tools or hoses attatched. I replaced the piston and sleave and the head seals. The piston and sleave were in very bad condition in spite of the compressor not being very old (about 3 years, only used occasionally). Before the repair the guage only went up to about 40 lbs. with the pump running constantly.
