Dumbest Mistake Anyone Could Make With a $2000 Chainsaw! RUINED in an INSTANT!

What happens here

Cliff first attempts to pull the starter rope of the chainsaw, demonstrating that it's completely seized and cannot be turned over. This confirms the engine has internal damage preventing rotation. He then proceeds to remove the chainsaw's bar and chain. Using a 'Ratchet Squarench' (a specialized ratcheting wrench), he loosens the two nuts that secure the clutch cover and the guide bar. After removing these nuts, he detaches the clutch cover, which exposes the clutch mechanism, and then carefully removes the guide bar and the cutting chain. This step is highlighted as crucial for both safety during further disassembly and to make the chainsaw easier to handle.

Goal: Confirm the engine is seized and safely remove the chainsaw's cutting components.
