I have a Stihl 039 with 24" bar. It doesn't seem like it's pumping enough oil. I went through a tank of fuel and only used maybe 1/4 tank of oil. I pulled the bar, and started the saw, and oil did pump out, and the inlet hole looked clean. But when I felt the chain it was dry. BTW I have the oiler turned up to high. Any thoughts?
Thanks,
Mike
is the bar a new addition and what kind is it?
You want to make sure the bar groove is clean and the oil hole in the bar lines up with the oil hole in the power head when the chain is snug on the bar.
Also, there should be a wire that engages in a notch in the clutch hub that drives the oil pump gear.
Another thought is the filter may be plugged.
It's a Stihl Rollomatic ES bar. It's what originally came with the saw which I bought used, with very little use on it. Tonight is the first night I was able to give it some hard use, and that's when I noticed I wasn't getting much oil to the bar. I'll double check to make sure all the passages are clear, and also that wire.
Filter looks good, but I did find a fair amount of build up in the channel, made a modified screwdriver to get all the crud out of the channel, and blew the oil holes out with compressed air. Is there any way to flush to oil system to make sure there's no blockage? Thanks for the help.

I use a broken piece of hack saw blade facing backwards to clean out the bar groove.
Mike, are you using a winter weight bar oil?
You can check you output if you have a tack - I was told by Stihl that my 290 should put out between 6 and 15 ml per minute at 10000 rpm, depending on where the adjuster is set.
These saws use relatively little oil - mine uses half a tank of oil (oiler turned up to 11) on a tank of gas.
If there's a fine spray of oil off the bottom of the bar tip, Stihl says that's enough. Grab a piece of cardboard and try to make a puddle.
My chain always feels dry too, but there's lube there.
I'm using regular 30wt Husky bar oil. I assume the winter weight stuff is thinner? I was around 35 deg. when I was cutting. When I noticed that the chain was dry, I put the tip of the bar close to some light colored bark and cranked the saw up a bit. With my other saw, I can see a light spray of oil, not so with the Stihl. I also haven't tried it since I cleaned the groove and blew everything out real well. Didn't figure the neighbors would appreciate that at 11:00 at night. I'll let you know if I have success. Thanks for all the help.

Be sure to use winter bar oil , it is thinner and works better in these cooler temperatures.
I tried the saw after dinner tonight, and with the groove nice and clean, I'm getting good oil to the chain, that must have been the trouble. I'll switch to winter oil, and it should be even better.
Mike
Yay! :D
what kind of wood are you cutting that can make the diff. but you should use winter oil on the bar any ways.i get mine at fleet farm for 12.95 for 2 1/2 gallon jug..
I was cutting some big Maple, about all I could handle with the 24" bar.
