To start the McCulloch M5551SDV Lawn Mower, ensure the fuel tank is filled, the oil level is adequate, and the spark plug is connected. Then, engage the safety lever, pull the starter cord firmly, and the engine should start.
It is recommended to check the oil level before each use, clean the air filter every 25 hours of operation, sharpen or replace the blade as needed, and perform a full service annually, including oil change, spark plug replacement, and thorough cleaning.
If the mower doesn't start, check for fuel, ensure the spark plug is clean and properly connected, inspect the air filter for clogs, and confirm the safety lever is engaged. Additionally, make sure the starter cord is not damaged.
The McCulloch M5551SDV Lawn Mower is designed to run on unleaded gasoline with a minimum octane rating of 87. Avoid using fuel with more than 10% ethanol content.
To adjust the cutting height, locate the height adjustment levers on each wheel and move them to the desired position. Ensure all wheels are set to the same height for an even cut.
If the engine runs rough or stalls, check the air filter and clean or replace it if necessary. Ensure the fuel is fresh and the spark plug is clean and properly gapped. Adjust the carburetor settings if needed.
First, disconnect the spark plug for safety. Tilt the mower to access the blade, use a wrench to remove the bolt securing the blade, and replace it with a new one. Ensure the blade is securely fastened before using the mower.
To store the mower during the off-season, drain the fuel tank, clean the mower thoroughly, and store it in a dry, sheltered area. Consider removing the battery if applicable and lubricating any moving parts to prevent rust.
To improve cutting performance, ensure the blade is sharp and balanced. Mow when the grass is dry, and adjust the cutting height to suit the grass length. Regularly clean the underside of the mower to prevent grass buildup.
If the self-propel function is not working, check the drive cable for proper tension and adjustment. Inspect the drive belt for wear or damage, and replace it if necessary. Ensure the wheels are free from debris that might hinder movement.
