Toro 25.4cc 51947 Operator's Manual

To start the Toro 25.4cc 51947 Power Head, ensure the power head is on a flat surface. Set the choke lever to the closed position, press the primer bulb 5-6 times until fuel is visible, and pull the starter handle. Once the engine starts, move the choke lever to the open position.
First, check the fuel tank to ensure there is fresh fuel. Inspect the spark plug for fouling or damage and replace if necessary. Ensure the air filter is clean. Finally, verify that the engine switch is in the 'on' position.
It's recommended to clean the air filter after every 10 hours of use or more frequently in dusty conditions. Remove the filter, wash it with warm soapy water, rinse thoroughly, and let it dry completely before reinstalling.
Use a mixture of unleaded gasoline and 2-cycle oil in a 50:1 ratio. Ensure the gasoline has an octane rating of 87 or higher and the oil is specifically designed for air-cooled 2-cycle engines.
Excessive vibration can be caused by a loose or damaged attachment, an unbalanced cutting head, or engine issues. Check all attachments for secure fit, inspect the cutting head for damage, and ensure the engine is running smoothly.
Regular maintenance includes checking and cleaning the air filter, inspecting and replacing the spark plug annually, checking fuel lines for leaks, and cleaning the exterior of the engine. Regularly inspect attachments for wear and damage.
An engine running rough may be due to a clogged air filter, dirty fuel, or a fouled spark plug. Clean or replace the air filter, ensure fresh fuel is used, and inspect the spark plug for fouling or wear. Adjust the carburetor if necessary.
For storage, empty the fuel tank and run the engine until it stops. Clean the exterior and store the unit in a dry place. Remove the spark plug and add a few drops of oil into the cylinder, then pull the starter handle slowly to distribute the oil.
Ensure the cooling fins are clean and not obstructed. Check the air filter for clogs and ensure the fuel mixture is correct. Allow the engine to cool down before restarting. If overheating persists, consult a professional technician.
To attach accessories, align the shaft of the attachment with the power head coupling and slide it in until it clicks. To detach, press the release button and pull the attachment out of the coupling. Ensure the engine is off before performing these actions.
