If a chainsaw cuts at an angle rather than cutting straight, then the problem most certainly lies in the guide bar and chain assembly. Adjust the chainsaw bar: If possible, adjust your chainsaw bar on a bench before continuing. Use a bar cleaner handle: A bar cleaner hook tool removes debris stuck in the bar’s rails.
Most of the time when a saw won’t cut straight, it’s caused by a problem with the saw chain. Most of the time, when a saw won’t cut straight, the chain is the culprit. Since a saw chain is a “Team” of cutter teeth, the cut will pull in the direction of the side whose cutter teeth take the biggest bites.
Your chain will have links on both sides of the chain. As I mentioned earlier, the chain is most likely the root cause of your problem, but if that’s not it, then it could also be your chainsaw bar. Use your gauge tool to clean the oil hole on both sides of the bar, to keep your chain running smoothly.
When the saw teeth become chipped, damaged or dull, the chainsaw likely won’t cut straight, especially if more teeth are affected along one side of the chain. Sharpen the teeth uniformly using a file and file guide, or take it to professional for sharpening. Madsen’s recommends using a grinder rather than a file, if you want to avoid taking it to a professional.
how to keep chainsaw cut straight Related Question:
How do I stop my chainsaw from cutting crooked?
Check the size of the top plates, which sit on the longer sections of each tooth on the chain. These top plates should be the same size. If some are shorter than others, file the longer ones down to match. Keep the same angle on all the top plates as you file – angles that don’t match also can cause curved cutting.
Why does my chainsaw keep cutting at an angle?
Uneven top plates can cause a chain to cut crooked. It’s important to keep all top plates equal length. Dull cutters damaged by rocks can cause a chain to cut crooked. It’s important to remove all damage from cutters prior to cutting.
Can a bent chainsaw bar be straightened?
Solid body bars with replaceable noses can be straightened by hammering with the bend peak up on a flat anvil. Laminated bars need a piece of rubberized belting of approximate 1/4″ thickness between bar and anvil to properly hammer straighten .
Why is my chainsaw blade smoking?
This most commonly is a result of a dull chain and exerting to much pressure on the bar and chain trying to make the chain saw cut. This could also be either a lack of bar and chain oil ( tank empty, restricted oiler hole ) or an inferior type of oil that is being slung off the chain and not lubricating.
Why is my chainsaw chain not tightening?
If you’re having trouble tightening the chainsaw chain, it may be adjusted properly already. Check the tension on the chain by grasping it in the middle of the top of the guide bar and giving it a quick snap. The chain should quickly snap back into place with no sagging on the underside of the guide bar.
Why does my chainsaw bar keep bending?
A saw that has had one side of the chain nicked on a rock or dulled in the dirt will cut in a circle. A chain that has been sharpened differently on one side of the chain than the other will cut in a circle. A bent bar might cut crooked or straight, but, it will get hung up in the kerf.
Why does my chainsaw blade go dull so fast?

How long should a chainsaw stay sharp?
A chainsaw may only need to be sharpened once a year if it is rarely used, but a tool that is frequently used will need to be sharpened regularly to ensure that the blade doesn’t get too dull. On average, a chainsaw blade will retain its sharpness for about 3 hours of actively cutting through wood.
Why is my chainsaw burning the wood?
Your chainsaw burns wood because of poor lubrication Lubrication allows the mechanical parts to coordinate much better by avoiding a phenomenon of friction which risks causing traces of burns. This is one of the main reasons that your appliance gives off too much heat and that the wood burns.
Why does my chainsaw chain keep stretching?
A chainsaw chain stretches and loosens from tension and extreme friction. The friction from cutting through wood makes the chain very hot and the heat causes it to loosen. The heat expands the guide bar and when it cools, the chain has stretched. The chain will also loosen as it wears down from use.
Can you over tighten a chainsaw chain?
There is a tension screw located near the base of the bar on the chainsaw. To tighten the chain, turn it clockwise, and to loosen turn it counterclockwise. Don’t over-tighten the chain as this could cause it to break.
Do chainsaw chains stretch over time?
Over time, the chain on your chainsaw will become loose, and new chains will stretch a lot more when you are breaking them in. You need to pay attention so that you can tighten a loose chain before you turn the chainsaw on, as loose chains are dangerous.
Is it worth sharpening a chainsaw chain?
Sharpening your chainsaw chain is definitely worth it as a sharp chainsaw chain is easier to work with. It takes less effort to cut through wood and your chain will make cleaner cuts with sharp blades. A chainsaw chain can be sharpened multiple times without much of a cost.
How often should a chainsaw bar be replaced?

How do you fix a pinched chainsaw bar?
To open pinched rails, mount the bar in a vice and gently tap on the bent rail with a hammer and punch. A flat-blade screwdriver is another tool that can be useful for prying open bent bar rails. Once you’ve got the pinch worked out, test your repair by placing the chain back in the groove.
