The McCulloch M51–190WR Lawn Mower is designed to use unleaded gasoline with an octane rating of 87 or higher. Avoid using gasoline with more than 10% ethanol content.
It is recommended to change the oil after the first 5 hours of use, and then every 25 hours of operation or at the beginning of each mowing season.
If the mower won't start, check the fuel level, ensure the spark plug is connected and in good condition, and verify that the air filter is clean. Also, make sure that the safety handle is fully engaged when attempting to start.
To clean the cutting deck, first disconnect the spark plug wire to prevent accidental starting. Then, use a hose to wash away grass clippings and debris. For stubborn residue, use a plastic scraper to remove it.
The cutting height can be adjusted using the lever located near the wheels. Move the lever to the desired position to achieve the preferred grass height. Ensure all wheels are set to the same height for an even cut.
Regular maintenance includes checking and cleaning the air filter, changing the oil, sharpening or replacing the blade, cleaning the cutting deck, and checking the spark plug condition.
To sharpen the blade, first disconnect the spark plug and remove the blade. Use a file or a grinding wheel to sharpen the blade, ensuring to maintain the original angle. Reinstall the blade securely after sharpening.
Excessive vibration can be caused by a damaged blade or loose components. Check the blade for damage and ensure all nuts and bolts are tightened. If the problem persists, consult a professional technician.
Before storing, clean the mower thoroughly and perform any necessary maintenance. Drain the fuel tank or add a fuel stabilizer, and store the mower in a dry, covered area to protect it from the elements.
