Toro 25.4cc 51944 Operator's Manual

To start the Toro 25.4cc 51944 Power Head, ensure the on/off switch is in the ON position, prime the engine using the primer bulb, set the choke lever to the starting position, and pull the starter rope briskly. Once the engine starts, move the choke lever to the RUN position.
The proper fuel mixture for the Toro 25.4cc 51944 Power Head is 50:1, which means mixing 2.6 ounces of two-stroke oil with one gallon of unleaded gasoline.
If the power head won't start, check the fuel mixture, ensure the spark plug is clean and properly gapped, inspect the air filter for cleanliness, and verify that the on/off switch is in the ON position.
The air filter should be checked and cleaned every 10 hours of operation or more frequently in dusty conditions. Replace the filter if it is damaged or extremely dirty.
Inspect the spark plug every 25 hours of operation. Clean the spark plug with a wire brush and check the gap, which should be set to 0.6mm (0.024 inches). Replace the spark plug if it is damaged or worn.
To maintain the fuel system, use fresh fuel, avoid storing fuel for more than 30 days, and use a fuel stabilizer if necessary. Periodically clean the fuel filter and inspect the fuel lines for any signs of wear or damage.
If the power head vibrates excessively, check for loose or damaged components, ensure the cutting attachment is balanced and securely attached, and inspect the engine mounts for wear.
The Toro 25.4cc 51944 Power Head is compatible with many universal attachments. However, it's recommended to use Toro-branded attachments to ensure optimal performance and fit.
To store the power head during the off-season, drain the fuel tank, run the engine until it stops to clear fuel from the carburetor, clean the exterior, and store it in a dry, secure location. Consider adding a few drops of oil to the cylinder and pulling the starter rope to distribute the oil.
If the engine runs erratically, check the air filter and spark plug for cleanliness, ensure the fuel mixture is correct, inspect the carburetor for blockages, and adjust the idle speed as needed.
