McCulloch M51-190AWFP Spare Parts List

To start the McCulloch M51-190AWFP Lawn Mower, ensure it has enough fuel and oil. Set the throttle to the 'start' position, pull the starter cord firmly, and allow the engine to stabilize before mowing.
Use unleaded gasoline with a minimum octane rating of 87. Avoid using E85 or other ethanol blends higher than 10%.
Change the oil after the first 5 hours of use to remove any particles from the manufacturing process. Subsequently, change it every 25 hours of operation or annually, whichever comes first.
If the mower won't start, check the fuel level, ensure the spark plug is clean and properly connected, and make sure the air filter is not clogged. Also, verify the safety lever is engaged.
To clean the air filter, remove the filter cover, take out the filter, and clean it with warm soapy water. Allow it to dry completely before reinstalling. Replace if it's damaged or excessively dirty.
Excessive vibration can be caused by a bent blade or loose parts. Inspect the blade for damage and ensure all nuts and bolts are tightened. Balance the blade if necessary.
Adjust the cutting height by using the lever located near the wheel. Move the lever to the desired position to raise or lower the mower deck.
Before storing for winter, drain the fuel, change the oil, clean the deck, and remove the spark plug. Store the mower in a dry and sheltered location.
To sharpen the blade, disconnect the spark plug, remove the blade, and use a file or bench grinder to sharpen it evenly. Reinstall the blade securely.
The recommended spark plug gap for the McCulloch M51-190AWFP is 0.030 inches (0.76 mm). Ensure the gap is set correctly for optimal performance.
