Hand-sharpening a chainsaw chain: 6 common mistakes

6 common errors

  1. Wrong file diameter (must match chain pitch)
  2. Wrong attack angle (30° standard)
  3. Wrong file height (upper 1/5 of tooth)
  4. Uneven tooth length (saw will drift)
  5. Forgetting depth gauges (re-set every 3 sharpenings)
  6. Filing in both directions (file works only on push)

Use a file holder with guide (12-20€) — pays back in saved chains.

Ask the AI mechanic — share your saw and chain reference, the AI returns exact file diameter and angle.
