If your chainsaw chain has stopped cutting after you had it professionally sharpened, there could be several potential issues to consider:

Chain Tension: Check the tension of the chain. If the chain is too loose or too tight, it can affect its ability to cut effectively. Follow the manufacturer’s guidelines for proper chain tension, which typically involve adjusting the tension screw or knob.

Chain Alignment: Ensure that the chain is correctly aligned on the guide bar. It should sit snugly in the bar groove with the cutting teeth facing forward. Misalignment can lead to improper cutting.

Dull Chain: Even after professional sharpening, the chain might not perform optimally if it’s been significantly worn down or damaged. Check if the chain teeth still have sharp cutting edges. If the chain has been sharpened excessively in the past, it may need to be replaced.

Chain Lubrication: Proper chain lubrication is essential for smooth cutting. Make sure the chain oil reservoir is filled, and the oiler is functioning correctly. A lack of lubrication can cause excessive friction and overheating, leading to poor cutting performance.

Chain Damage: Inspect the chain for any visible damage, such as broken or missing teeth. Damaged chains may not cut properly and should be replaced.

Guide Bar Condition: Examine the guide bar for any signs of wear or damage. A damaged or worn bar can affect the chain’s performance. Replace the guide bar if necessary.

Chain Sharpness: Even though the chain was professionally sharpened, it’s possible that it wasn’t sharpened correctly. Check the chain’s teeth for uniform sharpness, and if needed, touch up the cutting teeth with a file.

Wood Type: The type of wood you’re cutting can also impact cutting performance. Harder woods may require a sharper chain and more frequent sharpening.

Chain Age: Chains eventually wear out and may not cut as efficiently as they once did. If your chain is very old or has been heavily used, it might be time to consider replacing it.

If you’ve checked all these aspects and the problem persists, it’s a good idea to consult with the professional who sharpened the chain or seek assistance from a local chainsaw dealer or repair shop. They can inspect the chainsaw and chain to identify any underlying issues that may be affecting its performance.
