Selecting the Correct Chainsaw Bar Length Based on Engine Displacement
When you are choosing the length of the bar for your chainsaw, you must consider the relationship between the engine displacement and the length of the saw bar. The displacement of the engines saw determine the amount of power that the chainsaw will have, as well as the amount of drag that the saw bar can create. Should you use a bar length that is more long than the displacement of the engine, the engine will struggle to move the chain.
As a result, the engine will overheat, and the engine will suffer from increased wear. To prevent these issues, you must choose a bar length for your saw that corresponds to the engine displacement to ensure that the chainsaw performs corectly. The engine displacement of a chainsaw is measured in cubic centimeter.
Choose the Right Chainsaw Bar Length for Your Engine
The displacement of the engine determine the amount of torque that is available to pull the chainsaw bar through the wood. The greater the displacement of the engine, the more torque that it can provide to pull the saw bar through the wood, which allow the bar to be longer. As such, engine displacement and bar length is correlated with one another.
If you use a bar length for your chainsaw that is longer than the engines displacement is capable of handling, the chain speed will slow down as the engine struggle to move the chain continuously. For individual who perform light task with the saw, such as pruning and gardening, it is best to use a chainsaw with a small engine displacement and a short saw bar. This is because small engine displacements is best for performing light tasks.
Short saw bars also allow the chainsaw to be more easy maneuvered when performing tasks in tight space. Short saw bars also reduce the overall weight of the saw. A lighter saw reduce the fatigue that the individual must experience when using the saw.
For these reasons, it isnt a good idea to use a long saw bar with a small engine displacement. This will lead to the engine overheating due to the drag that the long bar create. For medium task, such as cutting firewood, it is best to use a chainsaw with a mid range engine displacement and a medium-length saw bar.
Chainsaws with mid-range engine displacements are the most common among homeowners due to the fact that they offer the best balance between power and weight of the saw. For these reason, if you attempt to use an engine displacement that is too small for your firewood task, the engine will struggle to perform at its necessary rate to maintain the chain speed required to cut through logs efficient. For professional task, such as felling large trees, it is necessary for you to use a chainsaw with high engine displacement and a long saw bar.
Large trees require a long saw bar to make deep incision into the trunk of the tree. Furthermore, the same amount of power that is needed to fell such large trees also require a high engine displacement to ensure that the saw chain move at a proper speed. If an individual attempts to use a low engine displacement for professional tasks with a long saw bar, the chainsaw will struggle to maintain its speed, and the chain will dull at a faster rate then it should.
The type of wood that you are cutting will also impact how well the engine and saw bar of your chainsaw work together. If you are cutting hardwoods, which are significantly denser than softwoods, there will be more drag on the saw bar when cutting such wood. The engine that may be capable of moving the saw bar through softwoods will not have the power to pull the same saw bar through hardwoods.
In this case, the engine will require a higher displacement to work efficient to pull the bar through hardwoods. To ensure that the engine and the saw bar work together properly for cutting wood, maintenance of the saw is necessary. The user must maintain the chain on the saw to ensure that it does not create excessive drag on the engine.
If you dont maintain the saw chain properly, it will work harder to cut the wood, which will lead the engine to overheat. By maintaining your saw properly, the engine and saw bar will remain in there proper working relationship with one another. Many individual make the mistake of purchasing a chainsaw model based off only on the length of the saw bar that it feature.
A long saw bar does not mean that the chainsaw will be more capable in performing its task. If you choose a saw bar that is too long for the engine displacement of the saw, it will struggle to perform task, will overheat, and will wear down at a significantly faster rate. In order to avoid these problem, ensure that the length of the saw bar match the engine displacement.
By following the guidelines provided by the manufacturer for these two specification, your saw will perform the task that were designed for it to do.
