Stihl FS 260 C FS 360 C Instruction Manual

To start the Stihl FS 260 C, ensure the stop switch is in the 'I' position, set the choke lever to the closed position, press the fuel pump bulb at least 5 times, and pull the starter rope until the engine fires. Then, move the choke lever to the open position and continue pulling the starter rope until the engine runs.
The recommended fuel mixture for the Stihl FS 360 C is a 50:1 ratio of unleaded gasoline to STIHL 2-stroke engine oil, ensuring the gasoline has a minimum octane rating of 89.
Check if there is fuel in the tank and that it is fresh. Inspect the spark plug for fouling and replace if necessary. Ensure the air filter is clean and the carburetor is properly adjusted. If problems persist, consult the user manual or a professional technician.
The air filter should be inspected and cleaned after every 10 hours of operation. Replace it if it is damaged or excessively dirty to ensure optimal performance.
To sharpen the cutting blade, secure the blade in a vice, use a flat file to sharpen each cutting edge, maintaining the original angle of the bevel. Ensure the blade is balanced after sharpening.
Regular maintenance includes cleaning or replacing the air filter, inspecting the spark plug, checking the fuel system for leaks, sharpening the cutting tool, and inspecting the drive shaft and gearbox for wear.
Excessive vibration can be caused by an unbalanced cutting attachment, loose parts, or worn components. Inspect the cutting tool and ensure it is not damaged or unbalanced, and check all nuts and bolts for tightness.
Use only the recommended line diameter and type specified by STIHL for the FS 260 C to ensure optimal performance and to avoid damage to the trimmer.
To adjust the carburetor, locate the adjustment screws marked 'H', 'L', and 'LA'. Adjust the 'L' screw for low-speed performance, 'H' for high-speed performance, and 'LA' for idle speed. Refer to the manual for specific settings and adjustments.
Always wear protective gear, including eye and ear protection, gloves, and sturdy footwear. Inspect the equipment before each use, and ensure all guards are in place. Be aware of your surroundings and avoid using the trimmer near people or pets.
