Dull teeth tend to drag through the wood, rather than slicing cleanly through it. As a result, uneven wear may cause the chain saw to pull in one direction or the other. A dull chain also produces sawdust instead of wood chips as it should. Inspect the teeth to ensure that they're all in place, not missing, and sharp, rather than dull, to rule out an issue with the chain. If necessary, have the chain sharpened or sharpen it yourself, if you have the knowledge.
When the teeth of the chain saw appear to be in good condition, move on to the next potential culprit, a bent or worn guide bar. Situate the chain saw on a hard, level surface and look down the length of the chain saw just as if you were looking down the barrel of a gun. If the bar leans to one side or another, it's time to replace it with a new one.
If the bar is straight, check for wear around the edges of the bar. Using a filing tool like this is better for your bar, and cheaper in the long run, compared to having someone grind the edge off at a saw shop.
The chainsaw bar groove gets oil, sawdust, and dirt caught in it. Use your gauge tool to clean the oil hole on both sides of the bar, to keep your chain running smoothly. This can also prevent smoking and overheating. If you did find something useful in this article, please share our website with someone else who might be interested in it.

You should not burn scrap lumber if it is treated, stained, or painted, because this will release toxic fumes into the air. It can also be dangerous to burn plywood, because of the adhesives it Not all firewood is created equal.
Some is great for campfires, some is excellent for smoking meat, and others kick butt when it comes to heat output. If your chainsaw is not cutting straight, this is due to one of two things: Your chain is dull on one side The edges of your bar are uneven There are a several ways these two things could happen. Your chain is dull on one side This is probably the most common reason that your chainsaw could be pulling in one direction.
When you hit dirt, or grind into a rock, that can take a big toll on your chain. So to summarize, if you have an uneven chain then it was probably caused by: Hitting dirt, a rock, etc. Check the setting for your chainsaw, and then use a depth gauge tool -- often combined with a file guide tool — to measure the depth gauges. Place the tool flat on top of the chain, allowing a depth gauge to slide upward through the tool's slot. It should be level with the top of the slot. If it's too tall, file it down, and then continue with the rest of the teeth.
If your chain is properly sharpened and maintained, the problem with your chainsaw could be a more complicated fix that requires the help of a professional to repair. If the guide bar is bent, the saw won't cut straight. Although this can often be repaired, it sometimes can't, which means you'll need to replace the chainsaw.
Make sure not to bind them when sharpening. If you force the carbide to spin when bound or caught against the cutting tooth it can cause extra wear or possibly break. Burs, rough edges, or too much pressure can all cause binding. There are several tips below that will help prevent this and make sharpening much easier. Carbides experience most wear the first time a chain is sharpened.
New or damaged chains may have rough edges or burs. This will grab or bind the carbide file if the sharpener is fixed solid in position. This is due to the carbide not seating properly and binding in the hook of the chain. To avoid this, seat the carbide into the chain by leaving the side knobs loose on the sharpener. You will need to hold the body, but this provides enough movement so that the carbide can spin freely. Sharpen each tooth of the chain very slightly.
This is only necessary the first time a chain is sharpened. A quick way to check uniform teeth length is with an adjustable wrench. Set the wrench to the same size as a cutting tooth and compare different cutting teeth.
If they are different it will affect performance.
