How to use
Install the BCS AT3 engine onto a compatible two-wheel tractor or implement following the manufacturer's mounting instructions and alignment points. Check and fill engine oil to the specified level for initial operation, add the correct grade of gasoline to the fuel tank, and verify that all linkages, drive shafts and fasteners are secured. Start the engine according to standard 4-stroke petrol engine procedures: ensure choke and throttle settings are appropriate for cold start conditions, use the recoil starter or electric start if fitted, and allow the engine to warm up at low load before engaging implements or heavy work.
Usage recommendations
Follow regular maintenance intervals: check oil level before each use, replace engine oil and oil filter per the service schedule, clean or replace the air filter as needed, and inspect spark plug condition. Use fresh fuel and avoid long-term storage with a full fuel tank. When mounting or removing attachments, ensure the tractor is secured and the engine is switched off and cooled. Consult the compatible two-wheel tractor or implement manual for torque settings and final installation instructions.
