i have a problem with my husky h1506f compressor, (model h1506f). the problem is it wont build pressure, i took it apart and the belt is fine, all the release valves are tightly shut. i even took off the line that comes from the piston to make sure that there was air being pumped. although im not sure how much air realy should pump through that line to the tank. i read on here beore that it may be the the pressure switch needing cleaned. im not sure what exactly the pressure switch is. if anyone can tell me anything more i would greatly appreciate it. my email is guinness45432yahoo.com , i did notice a little air coming fom around the gauges but i dont know if thats the pressure switch or if thats enoughe of a leak to stop a tank from filling, i think that line actually goes to the pressure gauge. thanks for any advise
