Understanding the Stihl FS 56 RC Throttle Trigger Diagram

The throttle trigger is the heart of your Stihl FS 56 RC. It controls the engine speed and, therefore, the power you deliver to the cutting head. A malfunctioning trigger can lead to erratic performance, reduced efficiency, and potentially dangerous situations. Before diving into assembly tips, let’s dissect the throttle trigger diagram.

Key Components of the Throttle Trigger Assembly

Here’s a breakdown of the essential parts, referencing a typical Stihl FS 56 RC throttle trigger diagram:

1. Throttle Trigger: The lever you squeeze to control the engine speed. This is the most obvious component.
2. Throttle Trigger Spring: Provides resistance and ensures the trigger returns to the idle position when released. Think of it as the “reset” button for your speed.
3. Throttle Cable: Connects the throttle trigger to the carburetor, translating your hand movement into engine speed adjustments. It’s the messenger between your hand and the engine.
4. Throttle Cable Housing: Protects the throttle cable and provides a smooth pathway for its movement. This keeps the messenger safe and on track.
5. Throttle Linkage: A series of levers and connectors that transmit the throttle cable’s movement to the carburetor. This is the interpreter, converting the message into engine action.
6. Interlock Lever: A safety feature that prevents accidental throttle engagement. You usually have to depress this before you can squeeze the throttle trigger. It’s the safety switch.
7. Housing Assembly: The plastic or metal casing that holds all these components together. This is the command center for the whole system.

Common Issues with the Throttle Trigger

• Sticking Trigger: Often caused by dirt, debris, or a lack of lubrication. This can make it difficult to control the engine speed smoothly.
• Broken Trigger Spring: Results in a trigger that doesn’t return to the idle position, potentially causing the engine to run at high speed even when you’re not squeezing the trigger.
• Snapped Throttle Cable: Prevents any throttle control. The engine will likely idle but won’t respond to the trigger.
• Loose or Disconnected Linkage: Can cause erratic engine behavior and poor throttle response.
• Worn or Damaged Housing: Can compromise the integrity of the entire assembly and affect its performance.

7 Pro Assembly Tips for Your Stihl FS 56 RC Throttle Trigger

Now, let’s get into the practical stuff. These tips are based on my own experiences and observations over years of using and maintaining Stihl trimmers.

Tip 1: Disassembly with Care – A Photographic Record

Before you even think about touching a screwdriver, take photos! Seriously. Disassembling the throttle trigger assembly can be tricky, especially if you’re not familiar with the inner workings. Use your smartphone to document each step of the disassembly process. Take close-up shots of how the spring is positioned, how the linkage connects, and the orientation of the cable. This photographic record will be invaluable when you’re putting everything back together.

Why this matters: I once spent an entire afternoon trying to reassemble a similar trigger mechanism because I hadn’t documented the disassembly. Trust me; a few photos can save you hours of frustration.

Tip 2: Cleanliness is Next to Godliness – The Power of Compressed Air

Once you’ve disassembled the throttle trigger assembly, clean all the components thoroughly. Use a brush, compressed air, and a solvent (like carburetor cleaner) to remove dirt, debris, and old grease. Pay particular attention to the throttle cable housing and the linkage points. A clean assembly will operate much more smoothly and reliably.

Data Point: According to a study by the Equipment Maintenance Council, regular cleaning and lubrication can extend the lifespan of small engine components by up to 30%.

My Experience: I’ve found that a simple can of compressed air is one of the most effective tools for cleaning small engine parts. It can reach into tight spaces and dislodge stubborn dirt and debris.

Tip 3: Lubrication – The Right Grease for the Job

Lubrication is crucial for smooth throttle operation. Use a high-quality lithium grease specifically designed for small engine components. Apply a small amount of grease to the throttle cable, the linkage points, and the trigger pivot. Be careful not to over-grease, as this can attract dirt and debris.

Technical Requirement: Use a grease with a temperature range suitable for the operating environment of your trimmer. A lithium grease with a temperature range of -20°F to 300°F is generally a good choice.

Strategic Recommendation: I prefer to use a grease gun with a needle nozzle for precise application. This allows me to get the grease exactly where it needs to be without making a mess.

Tip 4: Throttle Cable Adjustment – Finding the Sweet Spot

The throttle cable adjustment is critical for proper engine performance. If the cable is too loose, the engine may not reach full throttle. If it’s too tight, the engine may idle too high or even run at full throttle continuously. Consult your Stihl FS 56 RC owner’s manual for the correct throttle cable adjustment procedure. Typically, this involves adjusting the cable tension at the carburetor end.

Actionable Tip: Start by loosening the cable adjustment screw or nut. Then, gently pull the throttle cable until you feel a slight resistance. Tighten the adjustment screw or nut to secure the cable in this position. Check the throttle response by squeezing the trigger and ensuring the engine revs up smoothly and returns to idle when released.

Troubleshooting: If you’re having trouble adjusting the throttle cable, try watching a YouTube video specific to the Stihl FS 56 RC. Visual aids can be incredibly helpful.

Tip 5: Spring Tension – The Delicate Balance

The throttle trigger spring provides the necessary resistance to return the trigger to the idle position. If the spring is weak or damaged, the trigger may not return properly, leading to erratic engine behavior. Inspect the spring carefully for any signs of wear or damage. If it’s weak, replace it with a new one.

Real Example: I once had a Stihl trimmer that would idle too high, even after adjusting the throttle cable. It turned out the throttle trigger spring was weak. Replacing the spring solved the problem immediately.

Best Practice: When installing the spring, make sure it’s properly seated in its housing. A misaligned spring can affect the throttle trigger’s sensitivity and responsiveness.

Tip 6: Interlock Lever – Safety First

The interlock lever is a crucial safety feature that prevents accidental throttle engagement. Make sure it’s functioning correctly. It should require a deliberate action to depress the interlock lever before you can squeeze the throttle trigger. If the interlock lever is loose, damaged, or not working properly, replace it immediately.

Case Study: A local landscaping company reported a significant reduction in accidental trimmer injuries after implementing a strict policy of checking the interlock lever on all trimmers before each use.

Cost Consideration: Interlock levers are relatively inexpensive to replace. Don’t compromise safety to save a few dollars.

Tip 7: Reassembly – Patience and Precision

Reassembling the throttle trigger assembly requires patience and precision. Refer to the photos you took during disassembly. Start by positioning the throttle cable and linkage in their correct locations. Then, install the throttle trigger spring and the trigger itself. Finally, secure the housing assembly.

Pitfalls to Avoid:

• Forcing Components: If a component doesn’t fit easily, don’t force it. Double-check the orientation and alignment.
• Over-Tightening Screws: Over-tightening screws can damage the plastic housing. Tighten them just enough to secure the components.
• Skipping Steps: Don’t skip any steps in the reassembly process. Each component plays a vital role in the overall function of the throttle trigger.

Personalized Story: I remember one time, I got impatient and skipped a step while reassembling a throttle trigger. The trimmer ran fine for a few minutes, but then the trigger jammed, and the engine went to full throttle. It was a scary experience that taught me the importance of following each step carefully.

Beyond the Throttle Trigger: Essential Firewood Preparation Knowledge

While a well-functioning throttle trigger is essential, it’s just one piece of the firewood preparation puzzle. Here’s a deeper dive into the broader aspects of wood processing, relevant to anyone using a Stihl FS 56 RC for clearing brush and small trees for firewood.

Wood Species and Firewood Quality

Not all wood burns the same. Different wood species have different densities, moisture contents, and heat outputs. Here’s a quick guide to some common wood species and their suitability for firewood:

• Hardwoods (Ideal for Firewood):
  • Oak: High density, long burn time, high heat output. Considered one of the best firewoods.
    • Data Point: Oak typically yields around 28 million BTU per cord.
  • Maple: Good density, decent burn time, good heat output. A solid all-around choice.
    • Data Point: Maple typically yields around 24 million BTU per cord.
  • Ash: Easy to split, burns well even when slightly green, good heat output.
    • Data Point: Ash typically yields around 20 million BTU per cord.
  • Beech: High density, long burn time, high heat output, but can be difficult to split.
• Softwoods (Acceptable, but with Caveats):
  • Pine: Burns quickly, lower heat output, produces more smoke and creosote. Best for kindling or shoulder season fires.
    • Data Point: Pine typically yields around 16 million BTU per cord.
  • Fir: Similar to pine, burns quickly, lower heat output.
  • Spruce: Similar to pine and fir.

Insight: The higher the density of the wood, the longer it will burn and the more heat it will produce.

Actionable Tip: Learn to identify the different wood species in your area. This will help you choose the best firewood for your needs.

Green Wood vs. Seasoned Wood

• Green Wood: Freshly cut wood that has a high moisture content (often 50% or higher). Green wood is difficult to light, produces a lot of smoke, and burns inefficiently.
• Seasoned Wood: Wood that has been allowed to dry for a period of time, reducing its moisture content to 20% or less. Seasoned wood is easy to light, burns cleanly, and produces more heat.

Key Concept: Seasoning is the process of drying wood to reduce its moisture content.

Technical Requirement: Firewood should have a moisture content of 20% or less for optimal burning. Use a moisture meter to check the moisture content of your firewood.

Data Point: Seasoning wood for 6-12 months can reduce its moisture content by 50% or more.

The Art of Stacking Firewood for Optimal Drying

Properly stacking firewood is crucial for efficient seasoning. Here are some tips:

1. Choose a Sunny and Windy Location: This will help the wood dry quickly.
2. Elevate the Wood: Use pallets or wooden beams to keep the wood off the ground. This will prevent moisture from wicking up into the wood.
3. Stack the Wood Loosely: Allow for air circulation between the logs.
4. Cover the Top of the Stack: Use a tarp or roofing material to protect the wood from rain and snow. Leave the sides open for ventilation.
5. Orient the Stack to Prevailing Winds: This will maximize air circulation through the stack.

Original Research: A study conducted by the University of Maine found that firewood stacked in a single row with good air circulation dried significantly faster than firewood stacked in a large, tightly packed pile.

Budgeting Consideration: Building a simple firewood shed can be a worthwhile investment. It will protect your firewood from the elements and ensure that it seasons properly.

Chainsaws vs. Axes: Choosing the Right Tool for the Job

While the Stihl FS 56 RC is great for clearing brush, you’ll likely need a chainsaw for felling larger trees and bucking them into firewood-sized logs. Axes and splitting mauls are essential for splitting the logs.

Here’s a comparison of chainsaws and axes:

• Chainsaws:
  • Pros: Fast, efficient, can handle large trees.
  • Cons: Requires fuel and maintenance, can be dangerous if not used properly.
• Axes/Splitting Mauls:
  • Pros: Simple, reliable, no fuel required, good exercise.
  • Cons: Slower than a chainsaw, requires more physical effort.

Insight: Chainsaws are best for felling trees and bucking logs, while axes and splitting mauls are best for splitting logs.

Actionable Tip: Invest in a good quality chainsaw and axe. These tools will last for many years if properly maintained.

Tool Selection: For most homeowners, a mid-sized chainsaw with a 16-18 inch bar is a good choice. A splitting maul with a 6-8 pound head is a good choice for splitting logs.
