Stihl FS 56 RC Brush Cutter Details

The Stihl FS 56 RC brush cutter is engineered for ease of use and versatility, focusing on operator comfort and safety. A primary feature, indicated by the "C" in its model name, is the Easy2Start system. This technology significantly reduces the effort required to pull the starter cord, ensuring quicker and smoother engine starts. Complementing this, a manual fuel pump simplifies priming the carburetor, further enhancing the starting process for both cold and warm engines.

User comfort and control are paramount, with the FS 56 RC typically featuring a loop handle with a barrier bar. This configuration, denoted by the "R" in the model name, provides excellent maneuverability for trimming tasks and helps keep the operator's feet and legs clear of the cutting attachment. The machine also incorporates a carrying ring, allowing it to be balanced with a shoulder strap or full harness, which is essential for reducing fatigue during extended operation.

Safety is built into every aspect of the FS 56 RC. Users are strongly advised to wear comprehensive personal protective equipment (PPE), including goggles, a face shield, hearing protection, gloves, and sturdy clothing. Adherence to a minimum 50-foot (15-meter) safety zone for bystanders is critical due to the risk of thrown objects. The manual also emphasizes avoiding "drop starting" and always using two hands for firm control.

The FS 56 RC supports a range of cutting attachments to suit various tasks. This includes several STIHL mowing heads like the AutoCut, which automatically advances line when tapped, and the PolyCut, which uses durable polymer blades with clear wear indicators. For tougher vegetation, grass cutting blades, available in 4-tooth and 8-tooth designs, can be mounted. It is crucial to use the correct deflector for each attachment type to ensure safety and optimal performance.

Proper fuel and maintenance are vital for the longevity and performance of this two-stroke engine. It requires a specific mixture of high-quality unleaded gasoline (minimum 89 octane) and STIHL's 50:1 two-stroke engine oil. New machines benefit from a break-in period of the first three tank fillings, where high-rev operation should be avoided. Regular maintenance, such as cleaning the air filter and checking the spark plug, is crucial, along with proper storage that involves draining the fuel tank to prevent carburetor issues.

Frequently Asked Questions (FAQs)

Can't find the answer you need? Here are some frequently asked questions about the Stihl FS 56 RC Brush Cutter, and we answer them below.


What type of fuel does the Stihl FS 56 RC use?
The FS 56 RC requires a mixture of high-quality unleaded gasoline with a minimum octane rating of 89 (R+M/2) and STIHL's two-stroke engine oil at a 50:1 ratio. Fuels with more than 10% ethanol should be avoided.

How do I start a cold engine with the Easy2Start system?
First, press the manual fuel pump bulb at least five times. Then, press in the choke lever and turn it to the full choke position (g). Pull the starter grip steadily until the engine runs, then immediately blip the throttle to release the starting throttle and move the choke lever to the run position (F).

What cutting attachments are approved for the Stihl FS 56 RC?
Approved attachments include various STIHL mowing heads (SuperCut, AutoCut, TrimCut, PolyCut, FixCut) and grass cutting blades (230-4, 230-8). It's crucial to use the appropriate deflector and handle/harness combination for the specific cutting attachment.

Why does the cutting attachment continue to spin after I release the throttle?
This is known as the flywheel effect. The rotating cutting attachment continues to rotate for a short period after the throttle trigger is released due to inertia. Always ensure the cutting attachment has fully stopped before putting the machine down.

How often should I clean the air filter?
The air filter should be cleaned weekly, or more frequently under dusty operating conditions. It should be replaced if it's damaged or if cleaning does not restore engine power. You can temporarily knock it out or blow it with compressed air.

What safety gear should I wear when operating the FS 56 RC?
Always wear goggles or protective glasses with side protection, a face shield, hearing protection (ear plugs or mufflers), heavy-duty non-slip gloves, sturdy boots with non-slip soles, and snug-fitting, heavy-material long pants and clothing. A safety hard hat is also recommended where there's a risk of head injuries.

How do I adjust the idle speed if the cutting attachment rotates when the engine is idling?
If the cutting attachment rotates at idle, turn the idle speed screw (LA) counterclockwise until the tool stops moving. Then, turn the screw another full turn in the same direction. If the issue persists, have your STIHL dealer check the machine.

Can I use a metal blade for cutting woody material?
No, metal grass cutting blades are intended only for cutting grass and weeds. Using them to cut woody materials significantly increases the risk of blade breakage and serious injury. For such tasks, STIHL recommends using the appropriate cutting tools designed for woody materials if approved for your model.

How should I store the Stihl FS 56 RC for long periods (3 months or longer)?
First, drain and clean the fuel tank in a well-ventilated area, then run the engine until the carburetor is dry to prevent diaphragms from sticking. Remove, clean, and inspect the cutting attachment. Thoroughly clean the machine, especially cylinder fins and the air filter. Store it in a dry, secure location out of reach of children.

What is the recommended bystander distance when operating the brush cutter?
To reduce the risk of injury from thrown objects, bystanders should be at least 50 feet (15 m) away from the operating area. Any coworkers within this restricted area should also wear proper eye protection.

Is the FS 56 RC equipped with an anti-vibration system?
Most STIHL power tools, including the FS 56 RC, are designed with features to minimize vibrations. While not explicitly detailed as an 'AV system' in this manual section, STIHL generally emphasizes reducing vibration transmission to the operator's hands to mitigate the risk of conditions like whitefinger disease. Maintaining a firm grip, wearing gloves, and taking frequent breaks are recommended.
