I'm guessing a cord? That seems to be average for me...

I'm cutting mostly oak and silver maple with some ash. Does this seem unusual?

When I say dull, I mean slows down, while still spitting good chips.

I sharpen mine as soon as I feel the saw working harder than it should, I also touch the chain up everytime I put gas and bar oil in the saw. If the wood is clean, this is the only time the chain gets the file. I would rather go through chains because I am sharpening too much, if possible, than tax the saw too much running a dull chain. A chain is cheaper than a saw.

Depends.

Skidded wood, dirty wood, will have reaching for the file more often than a cord. Much more often, and more so with reg. chisel.

A touch up here and there when a fill break comes, and unless you find wire or something, there's never a dull chain.

Stay safe!

If the wood is dirty, check to make sure that the oiler is working, sometimes dirt will plug the oiler.

I file my chains on the bar about every tank full or even more often if the wood is dirty or I hit something. After about 3 tanks I take em off, clean the saw and bar, and file in a vise, and do the depth gauges. I only hand file and seem to have pretty good luck with it. I'm sure there's room for improvement on my part, I always try to get better at it.

Depends on how many rocks are under the log I'm cuttin'






On average hard locust or osage ? about every 2 tanks I'll hit it with a file.

Oak,black walnut or hickory about every 4-5 tanks.

as of recent I've been cutting silver maple...I have to stop cutting every few minutes because the bar will start to smoke. is that telling of a dull chain?

That can be a dull chain, but its more likely an oiling problem which also can be a rail groove issue. Also, it can be that you have your chain too tight..

Yes, all of the above:

my bar started smoking (it was still cutting and throwing chips)

I stopped the saw here is what I observed:

- chain had tightened up due to bar groove filled with chips to the extent chain was being pushed out of the groove

- chain was under oiled, bar oil port was plugged with chips.

lesson learnt due not use a low profile chain with the L-shaped type rakers (stock 6401 chain is all I had at the time) if you have the bar buried on a high HP (681) saw that can hit the limiter in the cut with full pressure on a new sharp chain.

My guess is the the L-shaped raker impedes chip clearance at high cutting speeds and feed rates

I find I get the best chip clearance running a longer bar (32") with skip chain, much easier cutting than the throw away 20" bar and chain combo's that come with many stock saws

indeed that is what was happening...

oiler was getting plugged with chips...even tho it sprayed oil when the bar was held to a piece of cut wood to verify flow, just not enough.

chips had indeed built up in the groove of the bar which caused some drag.

Thanks!

Note: Silver Maple ='s very hard wood!
