To start the Toro 21-inch 20888C mower, ensure that the fuel valve is open, the throttle lever is set to 'start,' and the safety key is inserted. Pull the starter handle briskly to start the engine.
Use SAE 30 oil for temperatures above 32°F (0°C) and SAE 10W-30 for temperatures below 32°F (0°C). Always refer to the owner's manual for specific recommendations.
The mower blade should be sharpened at least once a season or after every 25 hours of use to ensure optimal cutting performance.
If the mower does not start, check the fuel level, ensure the spark plug is connected, and verify the air filter is clean. Additionally, confirm that the safety key is properly inserted.
After use, turn off the engine and disconnect the spark plug. Use a garden hose to rinse the mower deck, being careful not to splash water on the engine. Dry the mower to prevent rust.
Ensure the blade is sharp, the deck is clean, and the engine is running at full throttle. Also, adjust the cutting height to match the grass conditions.
To store the mower, clean it thoroughly, change the oil, and add fuel stabilizer to the tank. Remove the battery and store it in a cool, dry place. Cover the mower and keep it in a dry location.
Regular maintenance includes checking the oil level before each use, changing the oil and air filter every 25 hours, and inspecting the spark plug and blade every 50 hours.
To adjust the cutting height, use the lever located on each wheel. Raise or lower the mower to the desired height by positioning the lever into the appropriate notch.
Excessive vibration may indicate a loose blade, damaged blade, or engine issue. Check the blade for damage and ensure it is securely fastened. If the problem persists, consult a professional technician.
