Maintenance Tips
Maintaining your Craftsman riding lawn mower is essential for optimal performance. Regular maintenance helps prevent issues and keeps your mower running smoothly.
Regular Cleaning Schedule
Establish a regular cleaning schedule to maintain your carburetor’s efficiency. Clean the carburetor every 25 hours of use or at least once per mowing season. During this process, check for dirt, debris, and fuel residues. Remove the carburetor and clean it thoroughly with carburetor cleaner, ensuring all parts are free from obstructions. After cleaning, inspect the air filter every month; replace it if it’s dirty, as a clean filter aids in proper airflow and fuel mixing.
Storing the Mower Properly
Store your mower properly to prolong its lifespan and maintain carburetor health. Before storage, run the mower until the fuel tank is empty to prevent stale fuel buildup, which can clog the carburetor. Disconnect the battery and cover the mower with a weather-resistant tarp to protect it from elements. When storing, choose a dry, cool location for optimal conditions. If you’ll store it for an extended period, consider adding a fuel stabilizer before emptying the tank to keep fuel fresh.
