To start the Toro Whirlwind 21-inch 23002 Mower, first ensure the fuel tank is filled and the oil level is adequate. Move the throttle to the "fast" position, then pull the starter cord quickly.
Toro recommends using SAE 30 oil for temperatures above 32°F (0°C) and 10W-30 for temperatures below 32°F (0°C).
For optimal performance, sharpen the mower blade at least once every season or after 20-25 hours of mowing.
Check the fuel level, inspect the spark plug for wear or damage, ensure the air filter is clean, and verify that the throttle and choke are set correctly.
To adjust the cutting height, locate the height adjustment levers on each wheel and move them to the desired position, ensuring all wheels are set to the same level.
At the end of the season, perform an oil change, clean or replace the air filter, inspect and sharpen the blade, and drain the fuel system or add a fuel stabilizer.
Excessive vibration may be due to an unbalanced or damaged blade, loose hardware, or debris buildup. Inspect the blade and tighten any loose parts.
After each use, disconnect the spark plug wire, and use a hose to wash away grass clippings and debris from the deck. Use a scraper for stubborn residue.
The recommended spark plug gap for the Toro Whirlwind 21-inch 23002 Mower is 0.030 inches (0.76 mm).
To improve fuel efficiency, regularly maintain the mower by keeping the blade sharp, maintaining proper tire pressure, and ensuring the air filter and spark plug are clean.
