Cutting a fallen tree can be a challenging task, especially when it comes to avoiding the common issue of "pinching" your chainsaw. In this guide, we’ll provide you with clear and concise instructions on how to safely and efficiently cut a fallen tree without pinching your chainsaw. Whether you’re a seasoned woodsman or a beginner, this information is essential for anyone working with a chainsaw.
Understanding the Problem: What is Chainsaw Pinching?
"Pinching" is a term used to describe a situation where a chainsaw gets stuck in a cut due to the compression of the tree trunk, making it difficult to continue cutting. This can be dangerous and cause damage to your chainsaw if not handled properly.
Key Technical Details
Chain Brake: Make sure your chainsaw’s chain brake is in the disengaged position before starting. The chain brake is a safety feature that stops the chain from moving when engaged.
Chain Tension: Properly tension your chainsaw chain. An overly loose chain can lead to pinching, so ensure it is snug but not too tight.
Guide Bar Length: The length of your chainsaw’s guide bar should be appropriate for the size of the tree you’re cutting. Using a guide bar that’s too short can increase the risk of pinching.
Starting Position: When making your first cut, begin on the side of the tree facing away from where you want it to fall. This will help prevent pinching as the tree leans in the opposite direction.
Bucking Techniques: There are two common techniques for bucking (cutting a fallen tree into manageable pieces) without pinching:
a. The Top Cut and Bottom Cut: This technique involves making a top cut, which is an upward cut, a third of the way through the trunk on the side facing away from the desired fall direction. Then, make a bottom cut, which is a horizontal cut, meeting the top cut to create an opening. This allows the tree to fall without pinching your chainsaw.
b. The Open Face Technique: In this method, you start with a horizontal cut at a slight upward angle on the side facing away from the fall direction. This cut should extend a third of the way through the trunk. Follow this with a downward-angled cut to create an open-faced notch. This technique also minimizes the risk of pinching.
Proper Exploitation: How to Cut Without Pinching
Here are the steps to cut a fallen tree without pinching your chainsaw:
Safety First: Always wear the necessary protective gear, including a helmet, eye protection, hearing protection, gloves, and chainsaw chaps.
Assess the Situation: Evaluate the tree’s size and its lean. Determine the direction you want it to fall.
Choose Your Technique: Select the bucking technique that best suits the situation, either the Top Cut and Bottom Cut or the Open Face Technique.
Make Your Cuts: Begin with the appropriate technique. Ensure your chainsaw is in good working condition, and your chain is sharp.
Watch for Warning Signs: Pay attention to any signs that the tree may start to pinch your chainsaw. If you notice the tree binding on the blade, stop cutting immediately.
Emergency Procedures: If your chainsaw does get pinched, do not try to force it. Instead, use wedges or a pry bar to carefully free the blade.
Conclusion
Cutting a fallen tree without pinching your chainsaw requires careful planning, proper technique, and keen awareness of the potential hazards. By understanding the key technical details and following the steps outlined in this guide, you can safely and efficiently cut trees, making the process smoother and safer for both technical and non-technical users.
