Cleaning and Inspecting Parts
Once your lawn mower is fully disassembled, it’s time for a thorough cleaning and inspection.
Cleaning:
- Use a cleaning rag and a mild detergent to clean the engine, deck, and other parts. Make sure to remove any dirt, grass clippings, or debris.
- Check for rust or corrosion on metal parts. If found, use a wire brush or sandpaper to clean it.
- Inspect the blade for wear and tear. If it’s bent or dull, it may need to be sharpened or replaced.
- Inspect the belts and pulleys for wear and tear. They may need to be replaced if they are cracked or frayed.
Inspecting:
- Check the spark plug. The spark plug should have a clean electrode and a gap that is within the specified range for your lawn mower. If it’s fouled or worn, replace it.
- Check the air filter. The air filter should be clean and free of debris. If it’s dirty, clean or replace it.
- Check the carburetor. Make sure the carburetor is clean and free of debris. If it’s dirty, you may need to clean or rebuild it.
- Check the engine oil. The oil should be clean and at the correct level. If it’s dirty or low, change it.
Reassembly: Putting it All Back Together
Now that the cleaning and inspection are done, you’re ready to reassemble your lawn mower. Follow the instructions in reverse order, ensuring that all parts are securely fastened.
Reassembly Tips:
