To start the Toro 46-cm 20943 Mower, ensure the mower is on a flat surface. Check that the fuel tank is full and the oil level is adequate. Pull the safety bar towards the handle and then pull the starter rope firmly.
For the Toro 46-cm 20943 Mower, it is recommended to use SAE 30 detergent oil with an API service classification of SF, SG, SH, SJ, SL, or higher for optimal performance.
Sharpen the mower blade at least once per mowing season or when you notice the grass is not cutting cleanly. More frequent sharpening may be necessary if the mower is used on rough terrain.
If the mower won't start, check the fuel level, ensure the spark plug is clean and properly connected, and verify that the air filter is not clogged. Also, ensure the safety bar is engaged properly.
The recommended mowing height for the Toro 46-cm 20943 Mower is between 25 mm to 102 mm. Adjust the height based on the type of grass and the time of year.
After use, disconnect the spark plug wire for safety. Use a garden hose to rinse off grass clippings and debris from the underside of the mower deck. Dry thoroughly to prevent rusting.
To replace the spark plug, disconnect the spark plug wire. Use a spark plug wrench to remove the old plug. Install the new spark plug, ensuring it is properly gapped, and reconnect the wire.
Excessive vibration may be caused by a damaged or unbalanced blade. Inspect the blade for damage and replace if necessary. Ensure it is properly secured and balanced.
Change the air filter every 25 operating hours or at least once per season. More frequent changes may be necessary in dusty environments.
Before storing for the winter, drain the fuel tank and run the engine until it stops. Clean the mower thoroughly and change the oil. Store in a dry, covered area to protect from the elements.
