5. Disengage Choke: Move the choke lever to the 'Half Choke' or 'Run' position.
6. Restart Engine: Pull the starter cord again until the engine starts and runs.
7. Disengage Chain Brake: Once the engine is running smoothly, disengage the chain brake by pulling the lever back towards the handle.

4.2 Cutting Techniques

Always maintain a firm grip with both hands on the chainsaw handles. Ensure the chain is properly lubricated by checking the automatic oiler. Plan your cuts to avoid kickback and falling hazards.

• Felling Trees: Requires advanced technique and should only be attempted by experienced users. Always assess the tree's lean and surrounding area.
• Limbing: Remove branches from a fallen tree. Work from the base towards the top, supporting the branch to prevent pinching.
• Bucking: Cut a fallen log into shorter sections. Be aware of tension and compression in the wood to prevent pinching the guide bar.
