Inquiry (采购产品): Technical Question Hello, I just bought a Curtis-Toledo compressor. It is a 80 gal tank with a 7.5 HP motor. I believe the pump is a E-57. I am trying to get the pressure swtich to turn the compressor off completely at about 130-150 PSI and it doesn't matter which way the lock nut is turned clockwise or counterclockwise on the pressure switch the pump doesn't turn off. I am not what it could be. Do you have any advice. This compressor also has the sandblasting mode on it and I am not sure, which way the valve is suppose to be for it to be in sandblasting mode. Is the valve suppose to be open or closed for sandblasting mode? Any help would helpful.
