To start the Stihl FC-MM, ensure the fuel tank is filled with the correct fuel mixture. Set the choke to the start position, engage the throttle lock, and pull the starter rope until the engine fires. Once it starts, move the choke to the run position.
Check the fuel mixture to ensure it's correct. Inspect the spark plug for fouling and replace if necessary. Ensure the air filter is clean. If issues persist, consult the user manual or a professional technician.
The air filter should be checked and cleaned after every 10 hours of use. Replace it if it appears damaged or excessively dirty. Regular maintenance ensures optimal performance.
Use a fresh fuel mix of 50:1 gasoline to 2-stroke engine oil ratio. Using high-quality oil and fresh fuel helps maintain engine performance and longevity.
Regularly inspect the cutting blades for damage or dullness. Sharpen them with a suitable file when needed and ensure they are correctly aligned. Always disconnect the spark plug before performing any blade maintenance.
Excessive vibration can result from damaged blades or loose components. Inspect and tighten all bolts and nuts. Check the blades for damage and replace if necessary. If the problem persists, consult a professional.
Drain the fuel tank and run the engine until it stops. Clean the unit thoroughly, lubricate metal parts to prevent rust, and store it in a dry place. Covering it with a tarp or protective cover can help prevent dust accumulation.
Wear protective gear, including goggles, gloves, and ear protection. Ensure bystanders are at a safe distance, and always operate the unit in well-ventilated areas. Follow all safety guidelines in the user manual.
Routine maintenance should be conducted after every 25 hours of use or at the beginning of each season. This includes checking the spark plug, air filter, and fuel system. Regular maintenance ensures the longevity and reliability of the machine.
Inspect the air filter and clean or replace it if necessary. Check the spark plug for wear or fouling. Ensure the fuel mixture is fresh and correct. If the issue continues, it may need professional servicing.
