Fuel & Oil Mixture

This engine requires a precise 40:1 fuel-to-oil mixture. Using straight gasoline will destroy the engine.

1. Use fresh, unleaded gasoline with a minimum octane rating of 87.
2. Use a high-quality 2-cycle engine oil certified for air-cooled engines.
3. Mix in a clean, approved fuel container: Add 3.2 oz of oil to 1 gallon of gasoline.
4. Shake the container thoroughly before filling the trimmer's fuel tank.
5. Never store fuel mix in the trimmer for more than 30 days.

Tip: Use pre-mixed fuel from outdoor power equipment retailers for convenience and to avoid mixture errors.

Trimming Techniques

For efficient and safe trimming, follow these techniques.

1. Hold the trimmer at a slight angle, keeping the cutting head parallel to the ground.
2. Use a smooth, sweeping motion from side to side, moving forward as you cut.
3. For tall grass, work in layers from the top down.
4. Advance line by tapping the bump head on the ground at high RPM. Do not force it.
5. For edging, tilt the trimmer so the line cuts vertically along sidewalks or driveways.
6. Keep the cutting head clear of fences, walls, trees, and hard surfaces to avoid line wear and kickback.

WARNING! Never use metal blades or other attachments not specified by Craftsman for this model. Always inspect the area for rocks, wire, or debris before trimming.

Maintenance Schedule

Regular maintenance ensures long life and optimal performance.

Storage Instructions

Proper storage prevents fuel system issues and corrosion.

1. Empty the fuel tank or add fuel stabilizer. Run the engine for 2 minutes to circulate treated fuel.
2. Allow the engine to cool completely.
3. Clean the entire unit, removing grass and debris.
4. Store in a cool, dry place, out of reach of children.
5. Cover the unit to protect it from dust.

CAUTION! Never store the trimmer with fuel in the tank indoors or in an enclosed space where fumes could accumulate.
