Have a Rolair 5715k17 model compressor. Can not get it to stop charging on the standard on off mode but works perfectly in the continuous mode. Any ideas what to check?

no info generic answer is the comp level --how much oil was removed --and doubt wrong dip stick in unit --refer to your owners/operation paperwork --if not have do online search using make and model

remove from power, it is ac there no stored energy, but you can take a screwdriver and place across terminals if you are concerned.

They are usually located under the compressor.

It will be the "Bleeder Valve" or it is more commonly known as the Check Valve, this valve is normally located going into the tank or connected to the tank, the pipe goes from the tank to the pressure switch, it normally sounds like air is coming from the pressure switch but its actually the check valve i mentioned.

First of all, make sure the tank is totally drained of air and the compressor is not plugged in. Next, unscrew the check valve top, and remove the spring and valve. Have a look at the seat of the valve, to see if the seat is damaged, clean it (if necessary replace it with a new one) then check inside the housing itself to make sure there is no dirt etc inside, clean it, then put it all back together again.

That should do it, this happens a lot on these smaller compressors

By direct, you most likely mean continuous run where the compressor runs to set pressure then a spill valve or unloader will discharge the rest of the air. This can be done with a pilot valve available thru WWW.Grainger.com or ebay. Make sure that the thread sizes will work on your compressor. You do not have to remove the pressure switch, however the unloader must unload before the pressure switch setting. For an idea on plumbing, take a look at gas powered compressors or an electric RolAir compressor that has that feature installed. Good luck.

Go to the RolAir website (http://www.rolair.com/) and under Literature select Owner's Manual, hopefully your model is listed. You'll have to use the proper model number of your air compressor, PMP11MK238FI is the part number of the air pump only. If you need a breakdown of the pump try a site like http://www.ereplacementparts.com/, you can see a breakdown of the pump and order any parts you may need.

I have a Rolair two stage air compressor of similar design (5~7 hp range) has metal headvalve plate, aluminum head and cast body. The head bolts are torqued to 243 fp. May use as ballpark guide. Your compressor may have been made by Fini. Good luck.

the compressor has an internal overload to protect it from overheating. the compressor is cooled by the refrigerant passing over it. It could be a bad compressor,, bad charge of refrigerant, or simply dirty coils not allowing air movement
