I bought an old Sears 14" electric chainsaw model 315.34160 at a garage sale and cannot locate and online source for an instruction manual for it. I have used it several times after installing a new chain, and it cuts great, but cannot figure what one of the controls is. There are three knobs: One is a silver pushbutton that seems to manually pump oil onto the chain. A knob just next to it has to be the filler cap for the bar oil, and I have filled it. Right next to the filler cap is a black knob mounted on a threaded machine screw, that just moves up and down when unscrewed/screwed. What is that for? I was guessing it might set the rate of the oil flow with each button push, but that was just a guess. Also, how often does one need to manually push the button, in a typical cutting session? I pushed it every couple of minutes, and it overoiled the chain, causing sprayback. Also, any hitnts about where to find a manual would be welcome.
