Smoking bar/chain

[Slacker]

16" Stihl E Bar 3/8 .050 Oregon semi chisel. All in nearly new shape. Maybe 20 tanks on the pair.
Using green bottle box store bar oil.
It can be seen flying off the tip on cardboard. Definitely getting oil to the bar.
When I'm felling, using the dawgs and applying pressure, smoke comes off the bar. When I let pressure off and let it self feed, no smoke.
The bar oil seems thin. Do I need a thicker oil, better technique or something else?

Show a pic of those cutters. Maybe the chain isn't as sharp as it should be.

Winter bar oil and some thinner bar oils do that sometimes too

It's making noodles in softwood.
Chain is good to go. I'm going to change brands of bar oil and see what happens.

Green bottle the Itasca? I've used it before and it was good for me.

Is the chain self feeding?

Yes, no smoke when I let it self feed.
I only see smoke when I apply pressure such as when I'm felling, using the dawgs to kant. I think the bar oil is burning off.

Hard to tell from pic but looks like corner may be dubbed. Also looks to have negative hook

Agree.

Its semi chisel, so no pointy corner even when its new.

 

[Slacker]

Agree.

Bad pic.

I know

Hard to tell from that pic but that’s what it looks like

If a chain is cutting right I’ll have to have slight pressure to keep it being too aggressive, if you’re burning off the bar oil it’s too light or chain is dull and from look at the rakers of the safety chain you’re really laying into it to make it cut.

This is harvester chain but about the same thing just a different raker

What do the rails of your bar look like?

Like new.
Bar has 20 tanks tops.
Chain has half that.

A video helps a lot with these kinds of things...

Is the oiler turned up all the way? Oil can fly off the chain when revving it at the minimum oil pump setting once the chain gets soaked. If the chain is too tight (hard to turn by hand) it can easily heat the bar a lot. Also dogging it puts more load on the saw which tightens up on the chain adding friction to the sprocket tip and the side of the bar that is doing the cutting. Maybe file the depth gauges a little to help it feed faster with less pressure. Touch up the sharpness before each day of use.

Oil near its boiling point can evaporate easily into smoke as it is slung off the tip at high speed. I'd use normal (non winter) Husqvarna/ TSC County Line oil, it clings on very well. I think canola oil tolerates high heat, but it is also very thin.

Sometimes you just need to let it cool for a few seconds, and rev some extra oil on the bar.

You could clean out the sprocket tip bearing occasionally to reduce friction from sawdust and burned oil that might collect in it. I soak them in WD-40, then use a compressed air blow gun to spin the sprocket really fast, and that tends to sling out the dirt. Grease afterward.

In the roughly 10 tanks you have ran the chain, have you touched the rakers yet or just filed the chain and left the raker height alone? I think your pushing the saw through wood to compensate for rakers not biting enough wood. When you use your dawgs....its causing excessive heat. That could be a dull chain, it could be raker height to high. I don't think bar oil viscocity is your problem.
