Saw Chain Sharpening
The chain needs to be sharpened when:
1. Sawdust becomes powder-like. 4. You need extra force to saw with.
2. The cut path does not go straight. 5. Vibration increases.
3. Fuel consumption increases.
Be sure to wear safety gloves.
• Clamp chain saw guide bar in a vice to secure.
• Sharpen chain with a 3/16 (4.8mm) file and holder (Oregon part number 18228C) / Sharpening kit
(Oregon part no 90407)
• Place your file on the cutter and push straight forward. Keep the file position.
• After every cutter has been set, check the depth gauge and file it to the proper level.
• Make sure every cutter has the same length and edge angles as illustrated.
