Ihave a Husquvarna chainsaw I just sharpened but when it cuts into the log it curves to the right and jams halfway through the log.


first flip the bar over that will show if the bar is bent if still cuts wrong in the same direction then the bar is good and you didn't sharpen the chain the right way

The chain needs sharpened or replaced. You can purchase the tools from any hardware store, and sharpen the chain yourself in about 15 minutes. Don't worry, your saw is just fine!

The chain saw cuts through a log in a curve, and then will not cut. Depth gauges are correct and chain is sharp. Will plunge cut and cuts small logs, but will not go through a big log. What might be...


Cutting in a curve is either the cutters are longer on one side than the other, or the bar rails are badly worn, more so on one side.

When I cut,the kerf curves to the right.I am thinking the bar is worn out allowing the chain to move or the sharpen is lop sided.What do you think?


While it is possible that the bar is contributing to this problem, the usual cause is uneven sharpening of the chain iteself. The side toward which the chain moves is the sharper side and is cutting moredeeply than the other. The easiest way to prove this is to replace the chain with a new one. If the bar is the problem, the new chain will behave the same way.

Saw cut is not straight. It curves until it freezes the chain.


Hi, sounds like the blades on the chain are either blunt and need sharpening, or they have been sharpened at the wrong angle.
Hope this helps

Saw cut is not straight. It curves until the chain freezes. Model 330 type #1 Chain saw.


This problem is caused by sharpening the chain on one side more than the other or can be caused by having the angle wrong when sharpening one side which causes one side to cut better than the other. The only solution is to get it sharpened professionally. All chainsaw users have to do this every few times we sharpen them.

Curves to the right while cutting


Remove the bar and chain. Use a flat file to remove any burrs, wire edges, or uneven wear on the bar. The other possibility is it wasn't sharpened properly. I'd wager it is a wire edge. HTH

When cutting, as it progresses, the cut curves to the rught automatically.


Sharpening a chainsaw is an art. I wokred in the logging industry for 20 years before I was shown how to truly sharpen one well!

It appears that your problem has one of two causes.

1. Sorry, but you may not have filed the chain correctly, a common problem for newbies and some veterans. Ensure that all cutters are filed at the same angle (save your old chain and buy a new one for a quick solution). The file should be worked from the back of the tooth to the point ONLY. The file should be stroked at 90 degrees to the bar and parallel to the line that is inscribed on the tooth (if a line does in fact exist). Each raker should also be the same height - get a raker gauge from your chainsaw shop. If the rakers on one side of the chain are lower than the other side and/or the cutters are filed at significantly different angles on one side than the other the saw will cut in a curve.

If you look at the cutter from the side each one will show a quarter moon filing "circle" and both sides of the chain MUST be equal or close to equal. If one side has a moon and the other does not the saw will cut in a curve so severly it will bind in the cut.

2. A worn bar that is higher on one side of the chain groove than the other will also cause problems - a new bar is the only long term solution for this. The unequal height is caused by incorrect filing of the chain and long term use of the bar with this condition.

If the bar is in good condition and the rakers and cutters are filed properly you will not have to push on the saw to make it cut - it will pull itself through the wood. Indeed, before you buy a bigger saw to cut faster you should ensure correct filing - you may amaze yourself and your buddies!

Good Luck and Safe Cutting!

Chain saw cuts at an angle


I have seen this problem of a chain saw cutting at an angle brought up again and again on forums, and result in a variety of answers about sharpening the chain, or replacing the bar and/or chain. In a number of these requests for solutions, none of the advice has solved the problem. I have used chain saws for about 45 years now, and there is a condition that some chains develop with the pitch of the teeth or the guides...or both...that will cause them to cut to the left or right at an angle (usually left). While I have not figured out what causes this, I have solved the problem of correcting it. First, turn the nose of your bar and chain toward you on a bench, look down it like sighting a gun and take a look at each tooth and guide. If the saw is cutting left, the teeth or the guides (or both) on the left (while you are looking down the bar from its tip) will be pitched differently than the teeth and/or guides on the right. The pitch of those teeth or guides (those little ears that stick up about on-fourth inch in front of each tooth) will be: 1) too much in line with each other, or 2) the teeth or guides will be less pitched than the teeth or guides on the right side of the chain. Solution: take a large pair of lineman's pliers or similar pliers and pitch those teeth and guides to match those on the right side of the chain. Also, make sure the curved part of your chain teeth peek out around the outside edge of those guides. If the guides are directly in line with your teeth, they will hinder cutting by the teeth. You can do this with the chain on the saw if you don't have too much slack between the bar and the chain. Last, make sure that the chain guides are not as tall or taller than your teeth. If they are, you will need to file them down a little (with a flat file) until the teeth are slightly longer than the guides. Afterward, make sure the teeth on both sides are equally sharp, and go cut a straight cut! TennesseeBob
