Chain Sharpening & Tensioning

Sharpening: Use round file matching chain pitch (.325"). Maintain 30° cutting angle.

1. Secure bar. File each cutter from inside out at consistent angle.
2. Check depth gauges with gauge tool; file down if too high.
3. Tensioning: Loosen bar nuts. Adjust tensioning screw until chain snaps back when pulled from bar.
4. Retighten bar nuts. Recheck tension after brief run.

CAUTION! Wear gloves when handling chain. Over-tensioning can damage bar and chain.
