Felling trees demands meticulous planning and execution. First‚ thoroughly assess the tree’s lean‚ identifying the direction of fall and potential hazards like branches or nearby obstacles. For trees smaller than the chainsaw blade length‚ specific safety measures apply‚ but vigilance is key for all sizes.
Employ the proper cutting technique: create a notch on the side of the intended fall‚ followed by a back cut slightly higher. Avoid pinching the saw by ensuring the back cut doesn’t close on the bar during the fall. Maintain a clear escape path at a 45-degree angle from the tree’s fall line‚ and be constantly aware of your surroundings.
A. Assessing Tree Lean & Hazards
Before any felling attempt‚ a comprehensive assessment of the tree’s lean is paramount. Determine the natural direction the tree wants to fall‚ considering factors like wind direction and weight distribution. Look for signs of decay‚ dead branches (widowmakers)‚ or other structural weaknesses that could influence the fall.
Scan the surrounding area for potential hazards – buildings‚ power lines‚ fences‚ or even other trees that could be struck. Ensure a clear escape path‚ ideally at a 45-degree angle away from the anticipated fall line. Understanding these elements minimizes risk and allows for a controlled‚ safe felling operation.
B. Making Safe Cuts – Notch & Back Cut
The felling process relies on a precise notch and back cut; The notch‚ cut on the side of the tree in the desired fall direction‚ determines the tree’s hinge – controlling the fall. It should be approximately one-fifth to one-third of the tree’s diameter.
The back cut‚ made horizontally on the opposite side‚ should be slightly higher than the notch’s base‚ leaving sufficient hinge wood. Crucially‚ never cut completely through the tree! Maintaining hinge wood ensures a controlled fall. Always make your cut on the opposite side of the tree’s lean to avoid pinching the saw.
C. Avoiding Pinching the Saw
Pinching occurs when a tree’s weight compresses the saw bar‚ trapping it within the cut. This is a dangerous situation that can quickly become uncontrollable. To avoid this‚ always cut on the opposite side of the tree’s lean‚ as the weight can easily pinch the chainsaw if you don’t.
Using wedges driven into the back cut can help keep the cut open and prevent pinching‚ especially with larger trees. Maintaining a clear escape path is vital. If the saw does become pinched‚ do not attempt to force it out; shut it down and seek assistance.
VIII. Chainsaw Safety Best Practices
Never leave a running chainsaw unattended‚ even for a moment. Always engage the chain brake when moving between cuts or walking any distance.
