To start the brushcutter, ensure the fuel tank is filled and the switch is in the "On" position. Prime the engine using the primer bulb, set the choke to the start position, and pull the starter rope until the engine starts. Once started, gradually move the choke to the run position.
Use a mixture of unleaded gasoline and 2-stroke engine oil at a ratio of 40:1. Ensure the gasoline is fresh and the oil is specifically designed for air-cooled 2-stroke engines.
Check the fuel level and ensure the fuel mixture is correct. Inspect the spark plug for fouling or damage and replace if necessary. Ensure the air filter is clean and not clogged. Make sure the on/off switch is in the "On" position.
Regularly check and clean the air filter, inspect the spark plug, and replace it if worn. Keep the cutting head clean and inspect for damage. Check fuel lines for leaks and ensure the fuel is not stale.
Turn off the engine and disconnect the spark plug. Remove the trimmer head cover, and take out any remaining line. Cut a new line to the recommended length, thread it through the holes, and wind it evenly. Reattach the cover securely.
Always wear eye protection, gloves, long pants, and sturdy boots. Use hearing protection due to the noise level of the engine. Ensure there are no bystanders within the operating area.
Empty the fuel tank and run the engine until it stops to clear any residual fuel. Clean the exterior and inspect for any damage. Store in a dry, well-ventilated area away from direct sunlight.
Ensure the cutting attachment is balanced and not damaged. Tighten any loose components. Use anti-vibration gloves and take regular breaks to minimize exposure.
Check if the air filter is clogged and clean or replace it as needed. Inspect the fuel filter and ensure the fuel mixture is correct. Examine the exhaust for blockages and clean if necessary.
