Kubota KBC26H-RS Operator's Manual

The Kubota KBC26H-RS Brush Cutter requires a fuel mixture of 50:1 ratio of unleaded gasoline to two-stroke engine oil.
To replace the trimmer line, first ensure the brush cutter is turned off and cool. Remove the spool cap, take out any remaining line, and insert new line into the spool following the direction indicated. Wind the line evenly and reattach the cap securely.
Check the fuel level and ensure that the mixture is correct. Verify the spark plug is clean and properly gapped. Ensure the air filter is clean and the choke is in the correct position. If the problem persists, consult the user manual or a professional technician.
The air filter should be checked and cleaned after every 10 hours of operation, or more frequently in dusty conditions. Replace it if it shows signs of damage or excessive dirt that cannot be cleaned.
Drain the fuel tank and run the engine until it stops. Clean the exterior, especially the cutting head. Store the brush cutter in a dry, well-ventilated area, and cover it to protect from dust and debris.
Adjusting the carburetor should be done carefully. Locate the adjustment screws and turn them slightly while the engine is running to achieve the smoothest operation. Refer to the manual for specific instructions and consider professional assistance if unsure.
Regular maintenance checks include inspecting the spark plug, cleaning the air filter, checking for loose bolts and nuts, inspecting the cutting blade or trimmer line, and verifying the correct operation of controls and safety features.
Remove the blade according to the manual's instructions. Use a flat file or a sharpening stone to sharpen the edges evenly. Balance the blade before reinstallation to ensure smooth operation.
Check for any loose parts, unbalanced blades, or damaged components. Ensure the cutting attachment is installed correctly. If the issue persists, have the brush cutter inspected by a professional.
To reduce noise, ensure the exhaust system is intact and the muffler is functioning properly. Regular maintenance and using the correct fuel mixture can also help in minimizing noise levels.
