Does anyone know where the hand priming pump is located? My service manual mentions it, but that is all. I have a parts manual that does not show it. also the diesel/water bulb has a valve handle on it, and it doesn't mention which way is open or closed. would appreciate any help. just bought this used skid steer, it ran for about 5 min, I turned it off, the next day it ran about 1 min. and died. will not start. have charged the battery, just turns over but doesn't fire off
