Does the chain saw not cut straight? This is the wrong place.
Your chain saw should be straight. If you pull it to the left or right, there is a problem.
For chainsaw users, this is a very common problem. I have seen various explanations in online forums and discussion areas. Unfortunately, some of these suggestions are completely wrong.
If your chainsaw cannot cut straight, this is due to one of the following two reasons:
Boring on one side of your chain
The edges of the bar are not flat
These two situations can happen in a variety of ways. We will look at each problem one by one below, and then discuss how to solve the problem. This can happen to custom chain saw as well as straight chain saws.
Note: If you want to know if it is caused by the bending or bumps of the chain saw blade, this is not the case. Think about it, you can't cut sawn wood into a curved moon shape. If the curve is large, you may lose the chain. If you pull in one direction, that is one of the two things above.
Solve the problem now!
1. One side of your chain becomes blunt
This is probably the most common reason why a chainsaw might pull in one direction. Both novice and experienced chainsaw users may encounter this problem.
A. Causes of uneven chains
Imagine you are cutting down a fallen tree, and when you walk through the log, you hit a piece of soil. I did it and it happened.
When you touch the soil or grind into rock, it may cause huge losses to your chain.
I know what you are thinking, "du!". If you hit a stone with a chain, it will damage it. It is clear
However, what you may not have thought of is the fact that touching a rock will wear out the other side of the chain than the other end. Think about it, one side will bear most of the damage.
Therefore, if you want to figure out why a Straight chain saw can't be straightforward, ask yourself if you have been in trouble lately. If so, then your problem is almost certainly a blunt chain on one side.
Another reason is that your chain may be uneven and the sharpness may be off. If you are inexperienced and have been using manual files to hone the chain, then you may find it harder to polish the ground than the other side. The result is a "bend" cut.
In summary, if your chain is uneven, it may be caused by the following reasons:
Hitting dirt, stones, etc.
Run in your chain unevenly
B. How to repair uneven chains
If it's a minor situation, then you can fix it by using file sharpening the file chain until it flattens out.
Your chain will have links on both sides of the chain. There will be a thin line on each guide link and each tool link. See the image below for an example of this line. Want to learn more about chain anatomy? Check out this article.
Chain saw is not straight
The purpose of these lines is to show the point where the link can no longer be sharpened (for example, the maximum amount of metal that can be removed).
For our purposes here, the row can also be used as a comparison tool. It provides a consistent benchmark that can be used to compare the distance that the links at both ends are disconnected.
If the difference is significant, then you may want to professionally sharpen the chain at your local sawmill. If there are chips or breaks on the chain, it needs to be replaced.
C. How to prevent uneven chains
Okay, once your chain is fixed, run-in or replaced, you will want to keep it that way.
The best way is to avoid the above-mentioned causes of chain damage.
In other words, take extra precautions to prevent the chain from hitting soil or rocks. Of course, it may still happen from time to time, but most of us may be more cautious about it.
If you are cutting wood on the ground, try to stop about 6 inches from the ground, and then turn the log over to complete the felling on the other side. If this is not feasible and the log cannot be moved, try to keep the chainsaw on the ground to prevent/eliminate contact with the ground.
Another issue we talked about is uneven sharpening. To avoid this, please use a file with guidelines, for example: (for reference only-if you buy the file, I will get a commission). Using files in such a guide can smooth things out.
Fix the chainsaw to cut straight
You can also practice applying equal pressure when sharpening from both ends. This is a skill, and it may take some time to become proficient.
2. The edges of the bar are not flat
As I mentioned earlier, the chain is likely to be the root cause of the problem, but if it is not, then it could also be your saw blade.
A. Reasons for uneven bars
The edges of the Alm chain saw will inevitably wear out unevenly. The metal-to-metal friction between the guide plate and the chain will gradually wipe away the metal. The fastest side of losing material may depend on your dominant hand, the direction the tree is leaning, and other factors.
The best practice for experienced chainsaw users is to periodically flip the crossbar to balance the object. If you are not currently doing this, one edge of the lever may be shorter than the other edge (on either side of the chain groove).
B. How to repair uneven bars
You can trim uneven bars by filing the edges until they are level. See below to understand what I mean:
Chain saw is not straight
What you have to do is scrape the edge of the bar with the document while holding it as evenly as possible. This should be done every time you perform maintenance on the chainsaw.
Compared to someone grinding off the edges in a sawmill, using such a file tool is more suitable for your bar and cheaper in the long run.
C. A good rule of thumb to prevent uneven levers is to flip the saw blade every time you refuel.
On most chainsaws, you can do this in the following ways:
Remove the front panel. Lift the rod from the chainsaw.
Then, you delete the chain.
Finally, flip the column over and put everything back in place.
Bonus: keep the saw blade clean
The grooves of the saw blade can accumulate oil, sawdust and dust. As you can imagine, it would run better without all the garbage.
Using a gauge tool, slide it along the rod groove to remove it.
Clean the saw blade slot
In addition, you will not miss the oil hole.
Use a gauge tool to clean the oil holes on both sides of the guide rod to keep the chain running smoothly. This can also prevent smoking and overheating.
