To change the oil, ensure the mower is on a level surface. Run the engine for a few minutes to warm the oil, then stop the engine. Remove the oil fill cap and place an oil pan under the drain valve. Open the valve and let the oil drain completely. Replace the drain valve cap, fill with new oil, and check the level with the dipstick.
Use unleaded gasoline with an octane rating of 87 or higher. Avoid using gasoline with more than 10% ethanol, as it can cause engine damage.
Check the battery connections to ensure they are tight and free of corrosion. Verify that the fuel tank has sufficient fuel and that the fuel valve is open. Inspect the spark plug for wear or damage and replace if necessary. Ensure the parking brake is engaged and the mower blades are disengaged before starting.
Sharpen the blades after every 25 hours of use, or more frequently if you notice uneven or ragged cuts. Always balance the blades after sharpening to prevent vibration and damage to the mower.
Check for debris or obstructions under the deck and remove them. Inspect the blades for damage or imbalance. Make sure all bolts and connections are secure. If the problem persists, it may be necessary to consult a professional technician.
Remove the air filter cover and take out the filter. If it's a foam filter, wash it with warm, soapy water and let it air dry. If it's a paper filter, tap it gently to remove dirt and replace it if it's too dirty. Reinstall the filter and cover.
Uneven cutting may result from a misaligned deck, dull blades, or incorrect tire pressure. First, level the deck following the instructions in the owner's manual. Sharpen or replace the blades if needed. Lastly, ensure all tires are inflated to the correct pressure.
Locate the height adjustment lever on the mower. Move the lever to the desired cutting height position, ensuring it locks into place. For best results, change the height when the mower is not running.
At the end of the season, clean the mower thoroughly, change the oil, and inspect the air filter, spark plug, and blades. Drain or stabilize the fuel, and store the mower in a dry place. Consider removing the battery and keeping it in a cool, dry location.
Before storing, clean the mower and remove any grass clippings. Perform end-of-season maintenance, such as changing the oil and sharpening the blades. Store the mower in a dry, sheltered area, and cover it to protect it from dust and moisture. Disconnect the battery and keep it in a cool place if possible.
