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.

I have a huscavarna 435 chainsaw and after running a few minutes the chain locks up


You may have the chain tensioner set a little too tight.

Additional things to check:
  • The sprocket on the end of the guide bar is greased, and turning smoothly.
  • The chain brake is working correctly (not dragging or only partially disengaging).
  • The guide bar is straight, not bent or twisted, burr free, and the groove the chain travels in hasn't been squeezed together.
  • The chain tension is set correctly.
  • The chain oiler is functioning correctly (and you have a sufficient amount and correct type of bar oil).
  • Chain is in good condition, and the correct one for the saw. Make sure all of the links flex smoothly.
  • Chain is sharp. A dull chain will put more pressure on the guide bar because the cutting teeth aren't digging into the wood efficiently (and usually a person pushes harder on the saw when the chain is getting dull).

I have purchased Poulon pro 42cc 18 inch chainsaw. I am extremely satisfied with my chainsaw until now. I have only owned it for about two months. I only used it maybe 10 times for easy tasks. my chainsaw...


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!

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

Hi how to tune homelite 330 chain saw carby, idle


Before adjusting anything, check the fuel filter, air filter, and muffler for plugging. Check the condition of the fuel lines for decay or other damage. Tighten all carburetor fasteners. Make sure you have fresh fuel mix in the tank. Does the primer bulb pull fresh fuel into itself when pumped? Turn both jet screws CW to stops (lightly), then back out CCW 1-1/2 turns each. This is a basic setting and should allow the engine to start and run. Start the engine and allow it to warm up, then pull the throttle full on. Adjust H needle CW until the engine starts to speed up, but still 4-stroking. Proper final adjustment is when the engine 4-strokes unloaded, but immediately 2-strokes when cutting. Release the throttle and adjust L needle CW for fairly good idle, but still allows the engine to 'follow the throttle'. Adjust idle speed screw so that the chain stops turning, but the engine will continue to run. Hope this helps!

20" poulan chain saw cuts at angle


Hi
You must have hit a nail or stone with the one side of the chain. When the chain gets duller on one side than the other is what makes a saw cut at a angle. Get the chain sharpened and it should cut straight again.

Chain saw cuts great at start, not so good about 1/2 way


All things are possible but it isn't likely the bar is bent. Are you getting fairly large chips or sawdust? Try raising the rear of the saw a little when she quits cutting. so you have a small contact area instead of a wide flat cut. Run a flat file at an angle along both edges of the bar to remove any wire edge. Let me know what you find you have piqued my curiosity. Lou

I have a husqvarna 350 chainsaw, it wont cut straight throuh a log without cutting at an angle and getting jamed. what is the problem , any sharpening tips


THE ONLY THING THAT CAUSES A SAW TO CUT ON A CURVE IS THE CHAIN IS SHARPER ON ONE SIDE THEN THE OTHER AND IT PULLS THE SAW CHAIN TO ONE SIDE CAUSING THIS PROBLEM.
THERE IS NOTHING WRONG WITH THE SAW, IF YOU USE A FILE TRY A FILE GUIDE THEY WORK GREAT

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
