I put the kill switch in the off position and cranked the starter over till the oil light went out then started her up. Ran it at 2,000 rpms for a couple minutes before I reved it up any further. you'll need a good battery though if you have just changed the oil and filter cause it takes a bit of cranking to re prime the pump and fill the filter. I did this over a couple of different crankings to not over heat the starter
