DeWalt Compressor filling and purging cycle

I have a DeWalt D55141 air compressor that fills the tank to 175psi and then the 175 psi relief valve opens and then purges the tank pressure. The tank never reaches over 175 psi and the motor never shuts off when it reaches 175 psi. It just pumps to 175psi and then purges the tank and then starts the cycle all over again. Other than that, the compressor does well. Does anyone know what is going on here or what part I may have to replace? I tried replacing the relief valve thinking it may have been weak but same problem still exists. Please help....

Help with Dewalt D5514 Type 1 Belt Replacement

The first question is: which side of the belt faces in or out? The shiny side or the rougher side? My intuition tells me the not so shiny side since it presumably has more grip and the fan labeling is on the shiny side which would most like wear out and make it unreadable if an old one had to be replaced. Also, on a car's v-belt the ridges face inwards obviously to match the ridges on the pulley and I don't remember reading any fan labeling printed on those ridges. Was that a long-winded enough introduction?:D

Second, did I need to purchase part number 233804-43 TENSION SCALE (BELT TENSION TESTER). I stumbled upon this part/accessory(?) on the Dewalt Service Net site (DeWALT ServiceNET - Official Online Store for DeWALT, Porter Cable, Delta, and Black and Decker Parts).

Third, I haven't had this compressor for more than a year, is the belt breaking in half a common occurrence? When it broke, I was shutting it on and off manually because I was using HVLP paint sprayer and I didn't have another pressure regulator installed. Could this have ...
