To start the Toro 51908 Brushcutter, first ensure the switch is in the 'ON' position. Prime the engine by pressing the primer bulb 5-6 times. Set the choke lever to the 'Full Choke' position, then pull the starter rope briskly until the engine attempts to start. Once it attempts to start, set the choke lever to 'Half Choke' and pull the starter again until the engine starts.
The Toro 51908 Brushcutter requires a 50:1 mixture of unleaded gasoline and 2-cycle engine oil. Always use fresh fuel and mix it properly in a separate container before filling the brushcutter.
To replace the trimmer line, first turn off the engine and disconnect the spark plug. Remove the spool cap on the trimmer head. Take out any remaining line and insert new trimmer line into the holes on the spool. Wind the line tightly and evenly onto the spool, then reattach the spool cap.
If the brushcutter won't start, check the fuel mixture to ensure it's correct and fresh. Inspect the spark plug for damage or fouling and clean or replace it as needed. Verify that the air filter is clean and not clogged. Finally, ensure all cables and connections are secure.
The air filter should be checked and cleaned after every 5 hours of use. If you operate the brushcutter in very dusty conditions, consider cleaning it more frequently to maintain optimal performance.
To reduce vibration, ensure that the cutting attachment is properly balanced and tightened. Inspect the brushcutter for any loose parts or fasteners. Use anti-vibration gloves and maintain a firm grip on the handle while operating the machine.
Regular maintenance includes checking the spark plug, cleaning the air filter, inspecting the fuel lines, and tightening any loose bolts or screws. Additionally, lubricate the gear head and inspect the cutting attachments for wear or damage.
To store the brushcutter, first drain the fuel tank and run the engine until it stops to clear any residual fuel. Clean the exterior and remove any debris. Store the brushcutter in a dry, well-ventilated area away from direct sunlight or extreme temperatures.
If cutting performance decreases, check the cutting attachment for dullness or damage and replace it if necessary. Ensure the engine is running at full speed and that the trimmer line is the correct length and properly installed.
To adjust the carburetor, locate the adjustment screws on the carburetor. Start the engine and let it warm up. Adjust the screws slowly to achieve a smooth idle and optimal throttle response. Refer to the user manual for specific adjustment procedures and settings.
