The consequences of a chainsaw sawing crookedly
The fact that you get an uneven cut does not end there. In fact, the curved cutting part leads immediately to a list of negative consequences:
- Greater expenditure of physical effort on the part of the master, since the tool must be constantly kept in the correct position.
- Fuel consumption is increased as the trajectory of the saw part is increased.
- The asterisk wears out. She has an even greater burden than usual.
- Chainsaw tire wear.
- The efficiency of the petrol tool is reduced.
- Curved cut. For firewood and felling the forest, this does not play a role, but this option will no longer work for cutting boards - all parts will turn out to be marriage.
- Discomfort at work caused by excessive physical exertion (item 1).
There are several main reasons why a chainsaw cuts sideways:
- Incorrect sharpening of teeth.
- Incorrect chain selection for sprocket and bar. The same applies to the last two details in relation to a properly selected chain.
- The chain is not tightened.
- Wear of the working part of the tool.
Why the chainsaw cuts crookedly - uneven sharpening is to blame
Any saw blade sharpening manual states that the teeth are ground at an equal distance. This does not depend on the location of the spare parts.
Such a simple requirement will protect both the chain and the master from being pulled towards the working link. Uneven sharpening is the most common cause of crooked cut logs.
File sharpening does not control the distance between the teeth and the length of the grind. Plus, the parts wear out unevenly: one side is larger, the other is smaller, and everything needs to be sharpened evenly.
What is the way out of the situation: give the chain for sharpening to the workshop or purchase your own machine for processing chainsaw consumables. With a hand tool, you will only bring more trouble to yourself. As a result, the chain on the chainsaw may not even turn, and these are new expenses.
Chain does not fit other accessories
The chainsaw tire has several operating parameters. One of them is the width of the groove for mounting the correct chain. This width can be of several sizes: from 1.1 to 1.6 mm.
For example: on a 1.3 mm tire, we installed a 1.1 mm consumable. At first, and with a strong tension, we will not notice a difference, but as soon as the tension weakens, the gap will not allow the chain to move evenly. We get the descent of the saw part to the side and the curvature of the cut.
It is better to buy a chain if you immediately indicate its exact dimensions, brand and model. Consultants in stores know what width and pitch is needed for such an apparatus. Or google your chainsaw on the Internet - you don’t need more information.
Excessive spare part wear
If your tool cuts crookedly, in an arc, then this affects the wear of the chain. You can check it with a visual inspection.
Remove the tire from the chainsaw and examine the part of the contact between the plane and the teeth of the chain. If it is wear, then you will clearly notice the curvature of one of the sides of the tool.
Traditionally, the saw should wear evenly. If the sharpening is larger on one of the sides, correct it or replace the defective spare part with a new one. Some manufacturers recommend turning the chain over from time to time so that the flow is uniform in all planes.
For some models, the last rule does not work if the manufacturer himself indicated the movement of the chains with arrows. It can only be installed in one direction.
