Toro 21-inch 26633B Operator's Manual

Ensure the fuel tank is filled and the oil level is adequate. Press the primer bulb three times, pull the safety bar towards the handle, and pull the starter rope with a smooth, steady motion.
Check the fuel level, ensure the spark plug is connected, and the air filter is clean. If the problem persists, inspect the fuel line for blockages or consult the user manual for additional troubleshooting steps.
Change the oil after the first 5 hours of operation, then every 25 hours of use or at least once a season. Use SAE 30 motor oil for optimal performance.
Disconnect the spark plug for safety, then tilt the mower so that the air filter is facing up. Use a hose to wash away grass clippings and debris. Avoid spraying water directly into the engine.
The Toro 21-inch 26633B Mower has a single-point height adjustment system. Simply pull the adjustment lever and move it to the desired cutting height position.
Excessive vibration may be due to an unbalanced blade. Inspect the blade for damage and ensure it is properly balanced. Tighten any loose components and check the wheels for alignment.
Clean the mower thoroughly, remove any fuel from the tank, and run the engine until it stops to clear the carburetor. Store in a dry, sheltered area, and place a cover over the mower to protect it from dust and moisture.
Ensure the blade is sharp and clean the deck regularly to prevent grass buildup. Mow when the grass is dry and avoid cutting more than one-third of the grass height in a single session for best results.
Wear appropriate footwear and eye protection. Clear the mowing area of debris and keep children and pets away. Never refuel the mower while the engine is hot.
Locate the air filter cover on the side of the mower. Remove the cover, take out the old filter, and replace it with a new one. Reattach the cover securely. Check the user manual for specific instructions related to your model.
