   • Place new gaskets (supplied with the RATION AT45026BEN carburetor) onto the mounting studs.

Operating Instructions

After successful installation, follow these general guidelines for operating your DR 26 Field Brush Mower with the new RATION AT45026BEN Carburetor.

1. Fuel Supply: Ensure the fuel tank contains fresh, clean fuel appropriate for your mower's engine.
2. Choke and Throttle: Set the choke to the appropriate starting position (usually "Full Choke" for cold starts). Set the throttle to a mid-range position.
3. Starting the Engine: Follow your mower's manufacturer instructions for starting. This typically involves pulling the recoil starter or engaging the electric start.
4. Warm-up: Allow the engine to warm up for a few minutes before engaging the cutting deck or applying full load. Gradually move the choke to the "Run" position as the engine warms.
5. Adjustment: If the engine runs rough or stalls, minor idle speed or mixture adjustments may be necessary. Consult a qualified technician if you are unsure.

Always operate the mower in a well-ventilated area and wear appropriate safety gear.

Maintenance

Regular maintenance of your RATION AT45026BEN Carburetor will prolong its lifespan and ensure consistent engine performance.

• Fuel System Cleanliness: Use fresh, clean fuel. Stale or contaminated fuel is a primary cause of carburetor issues. Consider using a fuel stabilizer if the mower will be stored for extended periods.
• Fuel Filter: Regularly inspect and replace the fuel filter according to your mower's maintenance schedule. A clogged fuel filter can restrict fuel flow to the carburetor.
• Air Filter: Ensure the engine's air filter is clean and free of debris. A dirty air filter can cause the engine to run rich and affect carburetor performance.
• Carburetor Cleaning: If performance issues arise, the carburetor may require cleaning. This involves disassembling the carburetor, cleaning jets and passages with carburetor cleaner, and replacing any worn gaskets or O-rings. This procedure should only be performed by individuals with mechanical experience.
• Storage: Before long-term storage, drain the fuel system or run the engine until it runs out of fuel to prevent fuel degradation and gumming in the carburetor.
