Troy-Bilt TB280-ES user manual

There could be several reasons why your Troy-Bilt TB280-ES lawnmower keeps shutting off. Here are a few possible causes:
1. Fuel-related Issues: Check if the fuel tank has enough gas and ensure it is not contaminated or stale. Old or bad fuel can cause the engine to stall. Also, make sure the fuel cap vent is open, allowing air into the tank to prevent a vacuum.
2. Carburetor Problems: The carburetor may be clogged or in need of adjustment. Clean or replace the air filter and inspect the spark plug to ensure they are in good condition. Additionally, the carburetor jets may need cleaning or adjustment by a professional.
3. Overheating: If the engine gets too hot, it may shut off as a safety precaution. Ensure that the cooling fins and engine components are clean and free from debris that may obstruct airflow.
4. Electrical Issues: Examine the spark plug wire and connections for proper fit and good condition. Faulty or loose wiring can cause intermittent power loss. Also, check the kill switch, ignition switch, and safety switches to ensure they are functioning correctly.
5. Blade or Drive Belt Issues: A loose, worn, or malfunctioning blade or drive belt may cause the engine to shut off. Inspect the blade for damage and ensure it is properly mounted. Check the drive belt to make sure it is in good condition and properly tensioned.
If troubleshooting these common issues doesn't solve the problem, it might be best to consult a professional for further diagnosis and repair.
