7. Pull starter rope to start.
8. Allow to warm up 30 seconds before disengaging chain brake.

Cutting Techniques: Use lower part of bar for cutting; maintain firm grip with both hands; never cut above shoulder height.

Chain Installation & Tensioning

Proper chain tension is critical for safety and performance.

1. Loosen bar nuts using combination wrench.
2. Lift bar tip slightly.
3. Turn tensioning screw clockwise to tighten until chain fits snug against bar.
4. Chain should pull smoothly around bar by hand without sagging.
5. Retighten bar nuts while holding bar tip up.
6. Recheck tension after first few minutes of operation.

Tip: Chain should be tensioned when cold. A properly tensioned chain will snap back when pulled away from bar.

Maintenance Schedule

Sharpening: Use round file matching chain pitch (typically 7/32" for 3/8" chain). Maintain 30° cutting angle. File all cutters to equal length.

Fuel & Lubrication

Fuel Mix: Use 89 octane or higher unleaded gasoline mixed with high-quality 2-cycle engine oil at 50:1 ratio (2.6 oz oil per 1 gallon gas).

Bar & Chain Oil: Use specially formulated chainsaw bar oil. Do not use waste motor oil or multi-grade motor oil.

Storage: For storage over 30 days, drain fuel tank and run engine until carburetor is dry. Store in dry, cool place.

CAUTION! Fuel is highly flammable. Mix and store in approved containers away from sparks or flames.

Storage Guidelines

Proper storage prevents fuel system damage and corrosion.

1. Clean entire saw of dirt, sap, and debris.
2. Drain fuel tank and run engine until it stops.
3. Remove chain, clean, and soak in oil.
4. Clean air filter and store separately.
