2. Safety Information

Always prioritize safety when operating power equipment. Failure to follow safety instructions can result in serious injury or property damage.

• Read the Entire Manual: Understand all operating instructions and safety warnings before starting the machine.
• Personal Protective Equipment (PPE): Always wear eye protection (safety glasses or goggles), hearing protection, long pants, sturdy footwear, and gloves when operating the trimmer.
• Clear the Area: Before starting, clear the work area of any debris, rocks, wires, or other objects that could be thrown by the cutting line. Keep bystanders, children, and pets at a safe distance (at least 50 feet/15 meters).
• Fuel Handling: Handle gasoline with extreme care. It is highly flammable. Refuel outdoors in a well-ventilated area, away from sparks, open flames, or heat sources. Do not smoke while refueling. Allow the engine to cool before refueling.
• Engine Operation: Never operate the engine in an enclosed area where carbon monoxide fumes can accumulate. Ensure adequate ventilation.
• Inspect Before Use: Check the trimmer for loose parts, damage, or wear before each use. Ensure the cutting line is properly installed and the shield is securely in place.
• Maintain Control: Operate the trimmer with a firm grip on the handles. Be aware of your surroundings and maintain stable footing, especially on uneven terrain.
• Avoid Contact: Keep hands and feet away from the rotating cutting line and other moving parts.
• Slope Operation: Exercise extreme caution when operating on slopes. Mow across the face of slopes, never up and down. Avoid excessively steep slopes.
• Storage: Store the trimmer in a secure, dry place, out of reach of children. Ensure the engine is cool before storing.

6. Maintenance

Regular maintenance ensures optimal performance and extends the life of your trimmer. Always turn off the engine and disconnect the spark plug wire before performing any maintenance.
