Proper engine maintenance is essential to save both time and money. Regular seasonal upkeep can significantly extend the lifespan of your engine. However, keeping up with all the necessary steps can be challenging. That's where B&S' comprehensive annual maintenance plan comes in handy—it makes it easy for you to stay on top of everything!
**Seasonal Maintenance**
Start by replacing the lawn mower oil and oil filter. Oil plays a crucial role in lubricating internal engine parts and reducing friction. Next, replace the air filter if one is installed, clean the cooling system, check the brakes, replace the fuel filter, and finally, swap out the spark plug. These routine tasks help ensure your engine runs smoothly and efficiently throughout the season.
**Winter Care Tips**
Before storing your engine for an extended period, make sure to fill the fuel tank completely. This helps prevent moisture buildup, which can lead to rust and corrosion. If the tank fills quickly, consider adding a Briggs Gasoline Stabilizer to the fuel. Run the engine for a few minutes so the stabilizer circulates through the carburetor. This prevents condensation from forming in critical areas like the fuel system or carburetor.
After completing these steps, remove the air filter and start the engine. While it’s running, spray a small amount of oil into the carburetor throat for about 5 seconds (for larger engines, extend this time slightly). Then turn off the engine, remove the spark plug, and spray a little oil into the cylinder one or two times. Before reinserting the spark plug, manually turn the engine over once or twice to lubricate the piston, rings, and cylinder walls.
Next, disconnect the negative battery cable and remove the battery. Clean the terminals with a Brayton battery electrode cleaner and apply Ballytone electrode protector. Store the battery in a cool, dry place to maintain its performance.
Before long-term storage, give your engine a thorough cleaning. Remove any grass clippings or debris from the surface. Disconnect the ignition high-voltage line and flush away any remaining rags with water. Use small tools—never your hands or feet—to clear any obstructions around the blade, and rinse the area with water.
**Spring Preparation**
After months of rest, your lawn mower is ready to go again. But before you start mowing, take a few simple steps to ensure a smooth restart. First, use high-quality engine oil—such as SE, SF, or SC grades, or a trusted brand like Bradley SAE30W. Second, fill the tank with fresh, clean gasoline. After 30 days, old gas can break down and cause starting issues. Avoid mixing old and new fuel. Lastly, install a new spark plug. Once the engine starts, the initial atomized oil will burn off, so a fresh spark plug is essential for reliable performance.
