Servicing a residential back generator. Natural Gas fueled. So happy the front housing cover comes off, made the oil change much easier. Using a pump to such l out the oil certainly speeds things along as well.
Generac transfer switch doesn't have the control to set the exercise time, unlike some other transfer switches, but I was able to set it through the control panel on the generator itself .
Many home generator units look alike, but have little differences in control panels, housings, and transfer switches. My job entails learning the differences and how to service and test whichever ones I come across.
