To start the Toro Sportlawn 20-inch 1003 Mower, ensure the fuel valve is open, set the choke to the 'start' position if cold, pull the starter handle smoothly until the engine starts, then adjust the throttle as needed.
Use SAE 30 oil for temperatures above 32°F (0°C) and 10W-30 oil for temperatures below 32°F (0°C) in the Toro Sportlawn 20-inch 1003 Mower.
Sharpen the mower blade at least once a season or after every 20-25 hours of use to ensure a clean cut and maintain optimal performance.
If the mower won't start, check the fuel level, spark plug condition, and ensure the air filter is clean. Additionally, confirm the choke is set correctly and the fuel is fresh.
To clean the mower deck, disconnect the spark plug, tilt the mower on its side, and use a hose or scraper to remove grass clippings and debris. Ensure the deck is dry before storing.
Adjust the cutting height by moving the height adjustment levers located near each wheel. Align the notches on the lever with the desired height setting.
The recommended maintenance schedule includes checking the oil level before each use, cleaning the air filter monthly, sharpening the blade annually, and inspecting the spark plug every season.
For winter storage, drain the fuel tank, clean the mower thoroughly, change the oil, remove the spark plug, and store the mower in a dry, sheltered area.
Excessive vibration may be caused by an unbalanced blade or debris buildup. Inspect the blade for damage, balance it, and clean the undercarriage to reduce vibration.
To replace the air filter, locate the air filter cover, remove it, and take out the old filter. Insert the new filter, ensuring it fits snugly, and replace the cover securely.
