Basic Cutting Techniques
- Stance: Maintain a wide, stable stance with your feet shoulder-width apart. Keep your weight balanced.
- Grip: Grip the chainsaw firmly with both hands. Your thumbs should be wrapped around the handles.
- Cutting: Let the chainsaw do the work. Don’t force it. Use a smooth, controlled motion.
- Kickback Zone: Be aware of the kickback zone, the upper quadrant of the bar tip. Avoid using this area to cut. Kickback can be violent and unexpected.
- Limbing: When removing branches from a fallen tree (limbing), start from the bottom and work your way up. This prevents the tree from settling on your cuts.
- Bucking: Bucking is cutting a log into shorter lengths. Use proper techniques to avoid pinching the bar and chain.
Advanced Cutting Techniques
- Felling: Felling a tree is a complex and dangerous task that should only be attempted by experienced operators. It involves making precise cuts to control the direction of the fall.
- Planning: Before felling, assess the tree for lean, wind direction, and any obstacles in the area.
- Notch Cut: Make a notch cut on the side of the tree in the direction you want it to fall. The notch should be about one-third of the tree’s diameter.
- Back Cut: Make a back cut on the opposite side of the tree, slightly above the notch. Leave a hinge of wood to control the fall.
- Felling Wedges: Use felling wedges to help direct the fall of the tree.
- Boring Cut: A boring cut involves plunging the tip of the bar into the wood. This technique is used for felling large trees and for creating notches.
Chainsaw Maintenance: Keeping It Sharp
A sharp chainsaw is a safe chainsaw. Dull chains require more force, increasing the risk of kickback and fatigue.
- Chain Sharpening: Learn how to sharpen your chain using a file or a chain grinder. Regular sharpening will keep your chainsaw cutting efficiently.
