I sharpened the chain correctly on my husqvarna chainsaw, but it still won't cut right? Does any one know what the problem would be?

Do you know how to sharpen the chain? How old is the chain, how much use is on that chain? I would go buy a new one and see if it works better, your current chain might be past its prime and wore out.

If you have sharpened many times and not ground down the rackers then it that is what seems to be happening.

Thats correct you need to make sure the rackers are lower then the actual blade part of the chain. if the rackers are higher then the blade it wont cut.

If you are using a machine to sharpen you chain, there is a square edged grinding wheel that can be used to grind the rakers/bumper uniformly. If you're doing this by hand, there is a gauge available that sits on the top of the teeth, allowing the raker to protrude through, which will indicate amount to be removed.

If it isn't evident why this must be done, look at the picture in the preceding post. You will note that the tooth slants downward away from the cutting edge and as you sharpen the tooth, its height is reduced as well. When it gets to the point that the raker is equal or greater than the tooth height, the tooth will not cut.

Ok, here is the full story, It is a chain that has only been sharpened once before. I was cutting a log and dug down into the ground. I saw some sparks and immediately stopped. When I tried to cut another log all it did was cut in a inch the start to smoke. I've sharpened each cutter 20 times each because after repeatedly sharpening them 5 times each it was still dull.

I haven't thought about filing down the rakers because the chain is so new. I filed each chain and a 30 degree angle also. The chain has oil on it when I sharpen it, so I'm pretty sure it's getting oil. I'll file the rakers and see what happens from there.

Good grief man, put oil in it. I have to fill the oil every time i refuel. It makes a huge difference.

To sharpen a chain correctly, you need to get the cutting angle, cross angle, chisel angle (or file depth) and raker depth just right.

If it's beyond your dedication, take it to a shop to get it sharpened, it's not expensive...

I use my chains until there's barely anything left to the teeth. I use a little Husky file guide (the kind with 2 rollers on it) and raker gauge when I sharpen...well the raker check is an occasional thing. They have one now that has both a file guide and raker gauge.

And to the OP, try not to run your chain into the ground, it dulls it :p

I bought an electric chainsaw sharpener from harbor freight for $40, I know it's cheap but it really works good. It isn't the hand held kind, you have to take the chain off and put it on the sharpener. Just got it a week ago, sharpened 2 dull 18" chains in about 20 minutes and they cut like new. Well worth the $40

I always hand sharpen my chains. I sent them out a couple of times and they came back with all the teeth "blued" from excessive heat. I change my files pretty often so it only takes a few strokes on each tooth.

Do the electric sharpeners all blue the teeth or is that just from someone getting too aggressive with it?

I have one of the chicago sharpeners from Harbor Freight. It does a good job. It will blue the teeth if you put too much pressure on it. I also put a drop of bar oil on each tooth before sharpening.

Be careful with the Harbor Freight sharpeners....
They're made out of some pretty weak plastic and seem to flex when sharpening.
Dont sharpen a stack of chains at one time...You'll be taking it back for a warranty.

Glad you got it cutting.

I hand sharpen my chains after 2 or 3 tanks of fuel, take the bar off and clean and flip it each time I do. One thing I do is save my stump cutting until the chain is already getting dull...there's always grit down low that dulls chains quickly.

Yes. This is the correct way. By doing that you dont need an electric sharpener. Arborists do it this way. All they carry is a round file and a flat file. I get lazy with the flat file at times and use my dremel.

I'm not sure if you mean you grind them all the way down or just to their recommnded depth. Cutting with them taken down too far can be very dangerous....much more prone to kicking back when it's biting too aggressively.

I don't grind them off.

Just give the cutting teeth a good healthy bite.

I'm aware that its not the recommended way of operation.

I keep a file & plenty of fresh chains. I'm not as good as they guy that says he can do it in a few minutes.

Maybe he can sharpen my hedge trimmers in a few minutes too. unless a few minutes means 20-30.

Right, you assume certain risks by partaking in many daily activities, however the discussion at hand is chainsaws.

If the OP is driving the saw into the ground, possibly running it without oil, and posting on here how to properly sharpen a chain, he strikes me as somebody who possibly should give the chainsaw work to somebody else.

BPS##

I'm pretty anal about my saw not getting stuck in the ground.
If nothing more its a completely unnecessary wearing out of the chain.
Not to mention that I hand sharpen my chains. Its a waste of time too.

True, hopefully they don't have accidents on their way to becoming experienced.

My dad taught me a lot about saws when I was still a teen.
I was given an old POS craftsman that made enough to pay cash for my next much better husky.
I decided that I wanted another bigger one by the time I was 19.

Still got it.... its barely been used in all these years.
Probably will always have that one. No more use than I have for one.
The occasional tree trim or cut down.

Even experienced cutters can get hurt. I got a good slap in the thigh yesterday by a branch under tension, and I looked things over pretty well before and while cutting. You should never ever be in a hurry with a chain saw and I guess I was rushing a bit because I was loosing daylight. For a lot of the stuff that was dropped in piles I used my pole pruner since it was impossible to see what was what. I'm still cutting up stuff dropped by Irene on my back acreage. All of my trails are open now but there's still a lot of stuff to break down.

10-23-2011, 09:09 AM
Among the other four chainsaws, one is a Sthil ms190 we use for for irrigation operations & it will hit dirt often. Even though we clean out the hole as much as is possible, and clear dirt from the roots, the chain still hits dirt a lot when we cut out tree roots from broken pipe, etc. It's one of the reasons I don't sharpen by hand and keep at least one spare bar and 4 - 6 chains on board.

For occassional use, sure sharpen by hand... but for regular professional use, I want a factory sharp chain that hasn't been stretched out, overheated or has weakened links from overuse... specially when cutting hard woods.

But different strokes for different folks.

I fill the oil up every time that I change the gas, and the reason the chain was so dull was because there was some piece of metal imbedded in the tree. I think that it was a old bit of barbed wire. That means that even someone who knows everything about chainsaws, like yourself, couldn't have seen it coming. It really screwed the chain up which is why it took so long to sharpen

why do you change the gas? :laugh: sorry, i had to. Every time i fill the tank i fill the bar oil and adjust the chain. Every other tank of gas i fill the oil, adjust the chain and file the chain. When you do it that way it is never a big chore and your always sharp. I carry 1 new chain per saw i own. I will only change the chain if i hit metal as you said. If i mistakenly touch the ground i immedietly file the chain. One thing many pros do is use a skip tooth chain. A skip tooth has half the amount of filing and is easier and quicker to maintain.

Darryl G
10-23-2011, 07:16 PM
One thing I do is always fill the oil first so I don't forget. I was just out cutting and went through 3 tanks of gas and still not nearly done cutting up stuff. I'm just trying to drop the dangerous stuff at this point and get it all on the ground. Maybe I'll grab my camera some time so I can show you guys what a mess Irene made of my woods.
