2. Set master control to "I" (Run).
3. Press decompression valve (if equipped).
4. Set choke to full choke position.
5. Pull starter rope sharply until engine "pops".
6. Move choke to half-choke position.
7. Pull starter rope again until engine starts.
8. Allow to warm up at idle for 30 seconds before cutting.

Cutting Techniques: Use lower quadrant of bar for cutting. Let saw do the work; don't force. Plan escape path from falling tree or limb.

Maintenance Schedule

Regular maintenance ensures performance and longevity.

Chain Sharpening & Tensioning

Proper chain maintenance is critical for safe operation.

1. Tensioning: Loosen bar nuts. Turn tensioning screw until chain fits snug against bar but can be pulled by hand. Retighten nuts.
2. Sharpening: Use round file matching chain pitch (5/32" for 0.325"). File each cutter at 30° angle. Maintain equal length on all cutters.
3. Depth Gauge: Check depth gauges with gauge tool. File down if above recommended height.

Tip: A sharp chain reduces kickback risk and improves cutting efficiency.

Storage Guidelines

Prepare saw for storage to prevent fuel system issues.

1. Drain fuel tank and run engine until it stops to clear carburetor.
2. Remove chain, clean, and soak in oil. Clean guide bar groove.
3. Clean entire saw, removing sawdust and debris.
4. Store in dry, cool place, away from children.

CAUTION! Never store with fuel in tank for more than 30 days. Use fuel stabilizer if short-term storage is needed.
