Fixing chainsaw bar oil problem with your tire pump

Here's the third video in my series on getting bar oil to flow in the chainsaw.

Why does the saw have a oil flow problem to begin with?

I don't know. I'm guessing that an air bubble might be the cause but that is just a guess. I've had to use the air pressure a number of times to get the oil going again. (I'm just an occasional chainsaw user).

Most likely an air lock of the pump issue. Sometimes revving the engine from idle to full throttle no load a few times can restart the flow especially if the saw had been either ran dry of oil or has set and the oil has all leak out. Most of the time it is due to wear in the pump causing an internal air leak preventing it from sealing and not to prime.

Air pressure as described in the videos has always worked for me, but, what I would like to see is an oil tank cap with a rubber bulb built-in. So pressing or squeezing the bulb would provide enough internal pressure to break the gap in the oil flow system.

How old is the saw? Does Stihl use a check valve to prevent leaking oil when not in use? I think I would replace the oil pump as I wouldn't want the oiler to die while in the middle of cutting. It's a little work but they usually are cheap.

The saw is probably about 7 years old but not used many hours in total (the problem of oil flow came up when it was fairly new as the first video was done about 6 years ago). I have a spare pump and hose on hand but so far it seems as if the pump is not the problem. Judging from the number of views on one of my videos on how to fix this problem It seems reasonable to assume that others have had the same problem (otherwise or I'm pretty sure the views would be minimal).

Or a good advertisement for Husqvarna. The only time oil didn't flow on my husk was the oil line off the pump was cracked, fairly easy fix. on other hand my Echo 501p has more oil flow then any saw I seen, I had to put oil screw down to low.

Good guess, all Stihl's now have flip caps, but my husk 550xp has better flip caps, my son wont agree......

So, then, how do you get a Stihl to STOP puking oil after you put it away? Maybe a breast pump?
