Just make sure the hoses are clear and are connected right. These saws weren't the best at oiling when they work but I guess adequate. Make sure the line from the engine is hooked up, it provides the pulse. I've never tried it but I'd bet that you could hook up the lines like the Homelite Super 2 and leave that pump out and it would work.. I think on these saws the oil cap has to be air tight to pressurize the tank..
