Operating Instructions
Before operating the Bolens BL160, always ensure the area is clear of obstacles and people. Proper starting procedures, detailed in the official manual, are essential for reliable ignition. When trimming, maintain a safe distance from yourself and others, and avoid contact with hard surfaces to prolong line life.
Employ smooth, controlled movements, overlapping each pass slightly for a clean cut. Avoid forcing the trimmer; let the rotating line do the work. Regularly check the line feed and replenish as needed. PartsTree diagrams can help visualize the cutting head assembly. Always prioritize safety and follow all guidelines.
Starting the BL160
To start the BL160, ensure the fuel tank is filled with the correct fuel mixture (see Fuel System Maintenance). Prime the carburetor by pressing the primer bulb several times until fuel is visible. Set the choke to the ‘start’ position. Grip the starter handle firmly and pull briskly; do not pull the cord to its full extent.
Repeat this motion until the engine attempts to start. Once it sputters, move the choke to the ‘run’ position and continue pulling until the engine runs smoothly. If it fails to start after several attempts, consult the Troubleshooting section; PartsTree offers carburetor components if needed.
Trimming Techniques
When trimming, maintain a slight angle with the cutting head, avoiding direct contact with the ground to prolong line life. Use a sweeping motion, moving from left to right or right to left, overlapping each pass slightly for a clean cut. For thick weeds, gradually work your way through them, rather than attempting a single, forceful cut.
Be mindful of objects that could become projectiles. Always wear appropriate safety gear, including eye protection. Regularly check the line length and replace it as needed, referencing PartsTree for replacement line options. Avoid trimming near electrical wires or sensitive plants.
Proper Usage Guidelines
Always inspect the Bolens BL160 before each use, ensuring all components are securely fastened and the cutting head is properly installed. Operate the trimmer on a stable, level surface. Avoid using the trimmer in wet or damp conditions to prevent electrical shock and ensure optimal performance. Never modify the trimmer or use unauthorized parts; consult PartsTree for genuine replacements.
Maintain a firm grip on the handles during operation. Be aware of your surroundings and keep bystanders at a safe distance. Do not overreach or operate the trimmer from an unstable position. Follow all safety precautions outlined in the manual to prevent injury.
Maintenance Schedule
Regular maintenance is crucial for the longevity of your Bolens BL160. After each use, clean debris from the cutting head and shaft. Every 25 hours of operation, inspect and clean or replace the air filter – PartsTree offers replacements. Check the spark plug every 50 hours; clean or replace as needed.
Fuel system maintenance is vital. Drain the fuel tank before storing the trimmer for extended periods. Inspect fuel lines for cracks or leaks. Annually, consider a carburetor cleaning or adjustment to ensure optimal engine performance. Refer to diagrams on PartsTree for component locations.
Fuel System Maintenance
Maintaining the fuel system of your Bolens BL160 is essential for reliable operation. Always use a fresh fuel mix, adhering to the correct fuel mixing ratios – typically a 50:1 gasoline to 2-cycle oil blend. Regularly inspect the fuel lines for cracks, leaks, or deterioration, replacing them as needed.
If the engine runs poorly, carburetor adjustment may be required. Consult the engine manufacturer’s specifications for proper settings. Before prolonged storage, drain the fuel tank completely to prevent fuel degradation and carburetor clogging. PartsTree provides replacement carburetors and gaskets.
Fuel Mixing Ratios
Proper fuel mixing is critical for the Bolens BL160’s engine longevity and performance. The standard ratio is 50:1, meaning 50 parts gasoline to 1 part high-quality 2-cycle engine oil. Always use fresh gasoline with a minimum octane rating of 87.
Carefully measure both components; inaccurate ratios can cause engine damage. Pre-mixed fuel is available, offering convenience and ensuring correct proportions. Avoid using fuel containing ethanol exceeding 10%, as it can lead to carburetor issues. Refer to the engine’s documentation for specific recommendations, and PartsTree can assist with fuel system component replacements.
Carburetor Adjustment
Adjusting the carburetor on your Bolens BL160 ensures optimal engine performance. Typically, adjustments involve the idle speed screw and the mixture control screw. Begin by warming up the engine. The idle speed screw controls the engine’s speed when at idle, while the mixture screw regulates the fuel-to-air ratio.
Turn the mixture screw clockwise for a leaner mixture and counterclockwise for a richer one; Fine-tune until the engine runs smoothly. If issues persist, a carburetor cleaning or replacement, sourced through PartsTree, might be necessary. Always consult the engine manual for specific adjustment procedures.
Spark Plug Maintenance
Regular spark plug maintenance is crucial for reliable BL160 operation. Inspect the spark plug periodically for fouling, wear, or damage. A properly functioning spark plug ensures efficient combustion and easy starting. PartsWarehouse lists the MTD-753-06847 as a compatible replacement spark plug for the BL160 model.
Clean the spark plug with a wire brush if lightly fouled. Replace the spark plug if it’s heavily worn or damaged. Ensure the correct spark plug gap, as specified in the engine manual, before installation. A new spark plug contributes to improved engine performance and fuel efficiency, extending the life of your trimmer.
Air Filter Cleaning and Replacement
Maintaining a clean air filter is vital for optimal BL160 engine performance. A dirty air filter restricts airflow, reducing power and increasing fuel consumption. Regularly check the air filter for dirt and debris. PartsWarehouse identifies MTD-753-06417 as the correct air filter for this model.
For paper filters, gently tap to remove loose dirt, or use low-pressure compressed air, blowing from the inside out. Foam filters can be washed with mild soap and water, then thoroughly dried. Replace the air filter when it’s excessively dirty or damaged. A clean air filter ensures proper engine operation and prolongs engine life.
