5 Signs Your Chainsaw Chain Needs Replacing, Not Just Sharpening

It throws sawdust instead of clean chips A dull chain produces fine sawdust rather than wood chips. You also have to push harder to cut, and the cut surface looks rough or burned.

The drive links are visibly worn Check the small teeth that ride in the bar groove. If they are noticeably shorter or pointed, the chain is worn out.

The cutters are too short from repeated filing After several sharpenings, the cutting teeth become too short to cut effectively. If sharpening doesn’t restore performance, replace the chain.

There are broken or missing teeth A chain with a broken cutter cannot cut evenly and will pull to one side. Replace it rather than trying to repair it.

The tie straps show wear or the chain is stretched Worn tie straps between cutters indicate fatigue. A stretched chain will not stay tight on the bar and can derail at speed.
