Stihl 066 HP Power Tests: 5 Shocking Firewood Cutting Facts

The Stihl 066. The Magnum. The legend. I’ve spent countless hours with this beast, and I’m here to tell you it’s more than just a name. But like any tool, understanding its strengths and weaknesses is key to mastering it. Let’s dive into some facts that might surprise you.

1. The Horsepower Myth: It’s Not Just About Raw Power

We often get caught up in the horsepower figures – and the 066 boasts a respectable 7.1 bhp (brake horsepower) – but the real story lies in how that power is delivered. I’ve seen smaller saws struggle and larger saws bog down. The 066’s power band is wide and forgiving, meaning it maintains torque even under heavy loads.

The Shock: The true shock isn’t the peak horsepower, but the sustained power output. Many saws claim high HP but can’t maintain it during a long cut through dense wood. The 066 shines here.
My Experience: I once used a modified 066 with a dull chain to fell a massive oak. Despite the less-than-ideal conditions, the saw kept pulling, albeit slowly. A lesser saw would have stalled repeatedly.
Industry Insight: According to a study by the Forest Products Society, chainsaws with a broad power band and high torque significantly reduce operator fatigue and increase overall productivity by up to 15% in demanding logging operations.

2. Chain Speed Matters: More Than You Think

Chain speed, measured in feet per second (ft/s), is critical for efficient cutting. The 066, properly tuned, can achieve impressive chain speeds.

The Shock: A dull chain on a powerful saw is worse than a sharp chain on a weaker saw. I’ve seen guys pushing a dull 066, struggling to make a cut that a properly sharpened Stihl MS 261 could handle with ease.
Why It Matters: Higher chain speed means cleaner cuts, less vibration, and reduced strain on the engine. It also translates to faster processing times.
My Experience: I once clocked myself processing a cord of wood with two chains – one razor sharp, the other slightly dull. The difference was staggering. The sharp chain reduced my cutting time by nearly 30%.
Pro Tip: Regularly sharpen your chain and use the correct file size and angle. Invest in a chain grinder if you process a lot of wood.

3. Weight and Balance: The Unsung Heroes of Productivity

The Stihl 066 isn’t a lightweight saw. It tips the scales at around 15.4 lbs (without the bar and chain). This weight can be a factor, especially during long days of firewood cutting.

The Shock: The weight of the 066, while initially daunting, contributes to its stability and control. A lighter saw can bounce around more, leading to less precise cuts and increased fatigue.
My Experience: I initially struggled with the weight of the 066, but I quickly learned to use it to my advantage. Its heft allowed me to make smoother, more controlled cuts, especially when felling larger trees.
Ergonomics are Key: Proper posture and technique are essential when using a heavier saw. Take frequent breaks and avoid overreaching.
Industry Insight: A study published in the “Journal of Human Ergonomics” found that using ergonomically designed tools, even heavy ones, can reduce the risk of musculoskeletal disorders by up to 25% in forestry workers.

4. Bar Length and Wood Diameter: Finding the Sweet Spot

The 066 can handle a range of bar lengths, typically from 20 to 36 inches. Choosing the right bar length is crucial for safety and efficiency.

The Shock: Overestimating your bar length can lead to dangerous situations. Using a bar that’s too long for the wood you’re cutting increases the risk of kickback and reduces control.
My Rule of Thumb: Always choose a bar length that’s slightly longer than the diameter of the wood you’re cutting. This ensures you have enough cutting surface without overextending the saw.
Example: For logs up to 24 inches in diameter, a 28-inch bar is a good choice. For larger trees, a 32 or 36-inch bar might be necessary.
Safety First: Always maintain a safe distance from the bar tip and be aware of the potential for kickback.

5. Fuel Consumption: The Price of Power

The Stihl 066 is a powerful machine, and that power comes at a price – fuel consumption.

The Shock: Running a 066 all day can burn through a significant amount of fuel. Be prepared to carry extra fuel and factor in the cost of fuel when estimating your project expenses.
My Experience: I learned early on that proper tuning and maintenance can significantly improve fuel efficiency. A clean air filter, a properly adjusted carburetor, and a sharp chain can all help reduce fuel consumption.
Fuel Efficiency Tips:
- Use a high-quality two-stroke oil.
- Mix your fuel correctly (typically 50:1 ratio).
- Clean the air filter regularly.
- Keep the carburetor properly adjusted.
