Depending on how old it is. There is only going to be two options. #1. No adjustment can be done. #2 on the underside of the saw around the Bar side of the saw you may see a hole that looks deep but there is a flat head "screw" in it. Turn this to adjust the oil flow. If it is fairly old then you wont be able to adjust it.
