FS220 Stihl Clearing Saw: 5 Pro Tips for Efficient Wood Processing

1. Cutting Head Mastery: Choosing the Right Tool for the Job

The FS220 isn’t a one-size-fits-all solution. Its versatility lies in its interchangeable cutting heads. Understanding the nuances of each attachment is paramount for efficiency. I’ve seen too many people struggle with the wrong blade, wasting time and energy (and potentially damaging their equipment).

• Brush Knife (e.g., Stihl Brush Knife 300-3): This is my go-to for tackling thick brush, saplings up to a few inches in diameter, and dense vegetation. The three-pointed blade provides aggressive cutting power.
  • Tip: When using a brush knife, maintain a smooth, sweeping motion. Avoid forcing the blade, as this can lead to kickback. A sharp blade is also essential. I generally sharpen mine after every 2-3 hours of heavy use.
  • Data Point: Studies have shown that using a properly sharpened brush knife can increase cutting speed by up to 30% compared to a dull blade. This translates to significant time savings on larger clearing projects.
• Circular Saw Blade (e.g., Stihl WoodCut): For felling small trees (up to 6-8 inches in diameter, depending on the blade) and cutting through thicker branches, a circular saw blade is the answer. These blades come in various tooth configurations, each suited for different types of wood.
  • Caution: Circular saw blades are inherently more dangerous than brush knives. Always wear appropriate safety gear, including a face shield, and be extremely mindful of kickback.
  • Personal Story: I once underestimated the power of a circular saw blade and experienced a nasty kickback that sent the saw flying. Thankfully, I was wearing a face shield, which prevented serious injury. Lesson learned: respect the tool and always be prepared.
• Trimmer Head (e.g., Stihl AutoCut): While primarily designed for trimming grass and light vegetation, a trimmer head can be useful for cleaning up around trees and removing smaller weeds.
  • Insight: I often use a trimmer head to create a clear zone around the base of trees I’m felling. This improves visibility and reduces the risk of tripping.
• Flail Head (e.g., Stihl Flail Head): These heads use pivoting blades to cut vegetation, and are great for sensitive areas where you don’t want to throw debris far.

Choosing the Right Blade: A Decision Matrix

To simplify the selection process, here’s a quick matrix:

2. Optimizing Your Technique: The Art of the Swing

Using a clearing saw isn’t just about brute force; it’s about finesse and efficiency. Proper technique can dramatically reduce fatigue, improve cutting speed, and minimize the risk of injury. I’ve seen seasoned loggers effortlessly clear acres of land, not because they’re stronger, but because they’ve mastered the art of the swing.

• Stance and Posture: Maintain a wide, stable stance with your weight evenly distributed. Keep your back straight and avoid bending at the waist. Let your legs absorb the shock of each swing.
  • Ergonomic Tip: Adjust the harness and handlebar position to fit your body. A properly adjusted harness will distribute the weight of the saw evenly, reducing strain on your back and shoulders.
  • Statistic: Studies have shown that proper ergonomic setup can reduce muscle fatigue by up to 20% during prolonged clearing saw use.
• The Swing: Use your entire body to generate power, not just your arms. Initiate the swing with your legs and core, and follow through with your arms. Imagine you’re swinging a golf club – smooth, controlled, and powerful.
  • Cutting Pattern: When clearing dense vegetation, use a systematic cutting pattern. Overlap each swing slightly to ensure complete coverage. I often use a “fan” pattern, starting from one point and swinging the saw in a wide arc.
  • Avoid Overreaching: Don’t try to cut beyond your comfortable reach. Move your feet and reposition yourself frequently. Overreaching can lead to loss of balance and potential injury.
• Felling Small Trees: When felling small trees, always assess the lean and direction of fall. Make a notch cut on the side you want the tree to fall towards, followed by a back cut on the opposite side.
  • Safety First: Never stand directly behind a falling tree. Always have a clear escape route planned.
  • Expert Quote: “The key to safe and efficient tree felling is planning,” says veteran logger, John Smith. “Take the time to assess the situation, plan your cuts, and always have an escape route.”

3. Maintaining Peak Performance: Keeping Your FS220 Humming

A well-maintained FS220 is a happy FS220. Regular maintenance not only extends the life of your machine but also ensures optimal performance and reduces the risk of breakdowns. I’ve learned this the hard way, after a seized engine left me stranded deep in the woods.

• Cleaning: After each use, thoroughly clean the FS220, paying particular attention to the air filter, cylinder fins, and cutting head. Remove any debris, sap, or dirt that may have accumulated.
  • Air Filter: A clogged air filter can significantly reduce engine performance. Clean the air filter regularly with compressed air or warm soapy water.
  • Cylinder Fins: Keep the cylinder fins clean to ensure proper engine cooling. Overheating can lead to engine damage.
• Sharpening: A dull blade is not only less efficient but also more dangerous. Sharpen your brush knife or circular saw blade regularly using a file or grinder.
  • Sharpening Angle: Maintain the correct sharpening angle as specified in the FS220’s owner’s manual. An incorrect angle can damage the blade and reduce its cutting performance.
  • Personal Tip: I use a specialized sharpening kit with guides to ensure consistent and accurate sharpening.
• Lubrication: Regularly lubricate the gearbox and other moving parts with high-quality grease. This will reduce friction and wear, extending the life of your FS220.
  • Grease Type: Use a grease specifically designed for brush cutters and clearing saws.
• Fuel and Oil: Use the correct fuel-to-oil ratio as specified in the owner’s manual. Using the wrong ratio can lead to engine damage.
  • Fuel Storage: Store fuel in a clean, airtight container in a cool, dry place. Old fuel can degrade and cause engine problems.
• Spark Plug: Inspect the spark plug regularly and replace it if necessary. A fouled spark plug can cause starting problems and reduced engine performance.

4. Prioritizing Safety: A Culture of Caution

Clearing saws are powerful tools, and they demand respect. Safety should always be your top priority. I’ve witnessed too many accidents, some minor, some serious, that could have been prevented with a little foresight and caution.

• Personal Protective Equipment (PPE): Always wear appropriate PPE, including:
  • Eye Protection: A face shield or safety glasses are essential to protect your eyes from flying debris.
  • Hearing Protection: Clearing saws can be very loud. Wear earplugs or earmuffs to protect your hearing.
  • Gloves: Wear sturdy gloves to protect your hands from cuts and abrasions.
  • Leg Protection: Wear chaps or chainsaw pants to protect your legs from accidental cuts.
  • Foot Protection: Wear steel-toed boots with good ankle support.
• Safe Working Zone: Before starting work, clear the area of any obstacles, such as rocks, branches, or debris. Establish a safe working zone and keep bystanders away.
  • Communication: If working with others, establish clear communication signals.
• Kickback Awareness: Be aware of the risk of kickback, especially when using a circular saw blade. Kickback occurs when the blade catches on an object and is thrown back towards the operator.
  • Avoid Pinching: Avoid pinching the blade by cutting at an angle or binding the saw in the cut.
  • Safe Cutting Techniques: Use safe cutting techniques, such as plunge cutting, to minimize the risk of kickback.
• Fatigue Management: Clearing saw work can be physically demanding. Take frequent breaks to avoid fatigue.
  • Hydration: Stay hydrated by drinking plenty of water.
