Logging is a dangerous job that requires a lot of technical skills and knowledge. Loggers are responsible for cutting down trees, removing the branches and transporting the logs to the sawmill. During the process, they use a chainsaw to cut through the trees and remove the branches. However, there is a unique technique used by loggers that may seem counterintuitive to many people – running upside down bars.
Running upside down bars is a technique used by loggers to extend the life of their chainsaws. Chainsaws have a chain with sharp teeth that rotate around a guide bar to cut through the wood. The teeth of the chain can become dull over time due to the abrasive nature of the wood. Dull teeth can cause the chainsaw to work harder, causing it to overheat, and reduce its cutting efficiency.
Running upside down bars is a technique that involves flipping the guide bar of the chainsaw upside down. The chainsaw is held upside down, and the chain rotates around the bottom of the guide bar. This technique exposes the unworn surface of the guide bar to the wood, allowing the chain to cut more efficiently. As a result, the chain stays sharper for longer, and the chainsaw operates more efficiently.
Loggers typically use the running upside down bars technique on longer guide bars. Longer guide bars tend to wear out faster than shorter guide bars due to their length. When a guide bar wears out, it can become bent, which can cause the chainsaw to malfunction. Running upside down bars allows loggers to extend the life of their guide bars, reducing the need to replace them frequently.
Another advantage of running upside down bars is that it reduces the risk of kickback. Kickback occurs when the chainsaw hits an object in the wood, causing it to jump back towards the operator. Kickback can be dangerous and can cause serious injuries to the operator. Running upside down bars reduces the risk of kickback as the chainsaw is held in a position that is less likely to cause it.
Running upside down bars is not a new technique. It has been used by loggers for many years, and it is still used today. This technique requires a lot of skill and practice to perfect, and it is not recommended for inexperienced chainsaw users. The technique can be dangerous if not done correctly, and it is essential to follow proper safety precautions when using a chainsaw.
In conclusion, running upside down bars is a technique used by loggers to extend the life of their chainsaw guide bars. This technique allows the chainsaw to cut more efficiently, stay sharper for longer, and reduces the risk of kickback. While it is a useful technique, it requires a lot of skill and practice to perfect and should only be used by experienced chainsaw users. Proper safety precautions should always be followed when using a chainsaw.

Frequently Asked Questions (FAQs) for “Why Do Loggers Run Upside Down Bars?”
1. What is an upside down bar in logging?
An upside down bar in logging refers to the orientation of the chainsaw bar, where the top part is flipped to the underside, and the bottom part is flipped to the top. This is done to reduce wear and tear on the chainsaw bar and increase its lifespan.
2. Why do loggers run upside down bars?
Loggers run upside down bars to prevent the chainsaw bar from getting pinched in the cut, which can cause the saw to kick back and injure the operator. An upside down bar also allows the chainsaw to cut more smoothly and efficiently, as the weight of the chainsaw is better distributed over the bar.
3. Does using an upside down bar affect the quality of the cut?
No, using an upside down bar does not affect the quality of the cut. In fact, it can improve the quality of the cut by reducing the risk of the chainsaw getting pinched in the cut and creating a smoother, more even cut.
4. Can any chainsaw be used with an upside down bar?
No, not all chainsaws can be used with an upside down bar. Chainsaws with a longer bar length and a higher horsepower are better suited for an upside down bar, as they can handle the extra stress and strain that comes with this orientation. It is important to consult the manufacturer’s guidelines before using an upside down bar with a chainsaw.
