Stihl FC 56 C Instruction Manual

To start the Stihl FC 56 C, ensure the stop switch is in the "I" position, engage the throttle trigger lock, set the choke lever to the cold start position, pull the starter rope until the engine fires, and then set the choke to the run position.
Use a 50:1 ratio of unleaded gasoline to Stihl 2-cycle engine oil. Ensure the gasoline has a minimum octane rating of 89 and avoid using ethanol blends above 10%.
To replace the cutting blade, disconnect the spark plug, use the locking pin to secure the drive shaft, remove the blade bolt with a wrench, replace the blade, and reassemble securely.
Check the fuel tank for proper fuel mixture, inspect the spark plug for fouling, ensure the air filter is clean, and verify the choke is set correctly.
Clean the air filter after every 5 hours of operation or more frequently if operating in dusty conditions. Replace the filter if it is damaged or excessively dirty.
After each use, clean the edger, check and clean the air filter, inspect the cutting blade for damage, and ensure all nuts and bolts are tightened.
Adjusting the carburetor should be done by a qualified technician. However, minor adjustments to the idle speed can be made using the idle speed screw, following the instructions in the user manual.
The correct spark plug gap for the Stihl FC 56 C is 0.5 mm (0.020 inches). Ensure the spark plug is clean and properly gapped for optimal performance.
For winter storage, empty the fuel tank, run the engine until it stops, clean the tool thoroughly, and store it in a dry, frost-free environment.
Check for a damaged or unbalanced cutting blade, inspect the drive shaft for wear, and ensure all fasteners are secure. If the problem persists, consult a service technician.
