5.3. Cutting Techniques

Always maintain a firm grip and stable stance. Plan your cuts to avoid kickback and ensure the material being cut is stable.

• Felling Small Trees: Make a directional notch on the side of the tree in the direction of fall, then make the felling cut from the opposite side, slightly above the notch.
• Limbing: Remove branches from a fallen tree. Work from the base towards the top, cutting smaller branches first.
• Bucking: Cutting a fallen log into smaller sections. Support the log to prevent pinching the guide bar.

• Chain Sharpening: A sharp chain is crucial for efficient and safe cutting. Sharpen the chain regularly or replace it when dull.
• Chain Tension: Check chain tension before each use. Adjust as necessary using the tool-free tensioning system.
• Cleaning: After each use, clean the guide bar groove, chain, and air vents to remove sawdust and debris.
• Oil Reservoir: Keep the chain oil reservoir filled with appropriate chain lubricant.
