Toro 21-inch 26638 Operator's Manual

To start the Toro 21-inch 26638 Mower, first ensure the fuel tank is filled with fresh gasoline and that the oil level is adequate. Turn the fuel valve to the 'ON' position, set the throttle to the 'FAST' position, and pull the starter rope firmly.
If the mower doesn't start, check the fuel level and ensure it's fresh. Verify that the spark plug is clean and properly connected. Also, make sure the air filter is not clogged. If issues persist, consult the manual or a professional technician.
It is recommended to change the oil in your Toro 26638 Mower after the first 5 hours of use and then every 25 hours of operation or at the beginning of each mowing season.
To clean the cutting deck, ensure the mower is turned off and disconnect the spark plug. Use a garden hose to wash away grass clippings and debris. For stubborn buildup, a brush or scraper can be used.
The Toro 26638 Mower is designed to run on unleaded gasoline with an octane rating of 87 or higher. Avoid using gasoline with more than 10% ethanol content to prevent engine damage.
To adjust the cutting height, locate the height adjustment levers on each wheel of the mower. Move each lever to the desired height position, making sure all wheels are set to the same height for an even cut.
Excessive vibration can be caused by a damaged blade or loose parts. Inspect the blade for damage and ensure it is securely fastened. Check for any loose bolts or components and tighten as necessary.
To replace the blade, disconnect the spark plug wire and turn the mower on its side. Use a wrench to remove the bolt securing the blade. Replace with a new blade, ensuring it is properly aligned, and tighten the bolt securely.
Uneven cutting can be caused by a dull blade or incorrect cutting height. Sharpen or replace the blade if necessary and check that the cutting height is set evenly on all wheels. Also, mow at a slower pace to ensure a clean cut.
For off-season storage, clean the mower thoroughly, including the cutting deck. Drain the fuel or add a fuel stabilizer. Change the oil and remove the spark plug. Store the mower in a dry, sheltered location.
