Stihl 056AV: A Deep Dive into the Specs

Before we dive into the tips and tricks, let’s establish a solid understanding of what makes the Stihl 056AV tick. This saw, produced from the late 1970s through the early 1990s, was a staple in the logging industry and a favorite among serious firewood cutters. Its reputation for durability and power is well-deserved.

• Engine Displacement: The heart of the 056AV is its two-stroke engine, typically displacing around 87 cc (cubic centimeters). This generous displacement provides ample power for tackling even the toughest hardwoods.

• Engine Power: Expect around 6 horsepower (4.5 kW) from this engine. While this may not sound like much compared to some modern saws, the 056AV delivers its power in a smooth, consistent manner, making it ideal for sustained use.

• Weight: This is where the 056AV shows its age. Weighing in at around 17-18 pounds (without the bar and chain), it’s significantly heavier than many modern saws with comparable power. This weight can be a factor, especially during long days of cutting.

• Bar Length: The 056AV can handle a wide range of bar lengths, typically from 16 inches up to 36 inches. The optimal length will depend on the size of the wood you’re processing. I’ve found a 20-inch bar to be a good all-around choice for most firewood applications.

• Chain Pitch: Typically uses a .404″ chain pitch, known for its aggressive cutting and durability.

• Fuel Tank Capacity: Approximately 0.8 liters. You’ll need to refuel periodically, so keep a fuel mixture handy.

• Oil Tank Capacity: Around 0.4 liters. Proper chain lubrication is crucial for the saw’s performance and longevity.

• AV (Anti-Vibration) System: The “AV” in the name stands for Anti-Vibration. The 056AV incorporates rubber mounts to isolate the engine and handle from vibrations, reducing operator fatigue. While not as advanced as modern systems, it’s a welcome feature.

Unique Insights: One of the things I’ve always appreciated about the 056AV is its simple design. There are no complicated electronics or finicky sensors to worry about. This makes it relatively easy to maintain and repair, even for someone with limited mechanical experience.

Data Point: A study conducted by a forestry equipment repair shop showed that the Stihl 056AV had a significantly lower failure rate due to electronic components compared to newer, electronically controlled chainsaws of similar engine size over a 20-year period. This highlights the benefit of its simpler, more robust design.

5 Pro Tips for Efficient Firewood Processing with the Stihl 056AV

Now that we have a good understanding of the saw itself, let’s get into the nitty-gritty of efficient firewood processing. These tips are based on my years of experience and are designed to help you get the most out of your Stihl 056AV.

Tip 1: Master the Art of Chain Sharpening

A dull chain is the enemy of efficiency. It not only slows down your cutting speed but also puts unnecessary strain on the saw’s engine and increases the risk of kickback. Sharpening your chain regularly is arguably the most important thing you can do to improve your firewood processing efficiency.

• Frequency: How often should you sharpen? The answer depends on the type of wood you’re cutting and the conditions. As a general rule, I sharpen my chain after every tank of fuel, or whenever I notice a decrease in cutting performance.

• Tools: You’ll need a few essential tools: a chainsaw file (typically 7/32″ for .404″ pitch chains), a depth gauge tool, and a flat file. A chainsaw vise is also highly recommended for holding the chain securely while you sharpen.

• Technique: The key to effective sharpening is consistency. Use smooth, even strokes, maintaining the correct angle and depth. Pay close attention to the manufacturer’s recommendations for your specific chain type.

• Depth Gauges: Don’t forget to check and file the depth gauges (also known as rakers). These control how much wood the chain bites into. If they’re too high, the chain won’t cut effectively. If they’re too low, the saw will be aggressive and prone to kickback.

Personal Story: I remember one particularly frustrating day when I was cutting some seasoned oak. I was struggling to make any progress, and the saw was bogging down constantly. After a few hours of struggling, I finally realized that my chain was incredibly dull. I took the time to sharpen it properly, and the difference was night and day. The saw sliced through the oak with ease, and I was able to finish the job in a fraction of the time. This experience taught me the importance of maintaining a sharp chain, no matter how tempting it is to keep pushing through.

Data Point: Studies have shown that a sharp chainsaw chain can increase cutting efficiency by as much as 50% compared to a dull chain. This translates to less time spent cutting, less fuel consumed, and less wear and tear on your saw.

Tip 2: Optimize Your Bucking Techniques

Bucking is the process of cutting logs into shorter, more manageable lengths for firewood. Efficient bucking techniques can significantly reduce the amount of time and effort required to process your wood.

• Planning is Key: Before you start cutting, take a moment to assess the log. Look for any bends, knots, or other irregularities that might affect your cutting strategy. Plan your cuts to minimize the risk of pinching the bar.

• Support and Stabilization: Ensure the log is properly supported to prevent it from rolling or shifting during cutting. Use wedges or other supports to create a stable cutting platform.

• Cutting Techniques: There are several bucking techniques you can use, depending on the situation.

  • Overbucking: Cutting from the top of the log down. This is generally the safest method, as gravity helps to keep the cut open.
  • Underbucking: Cutting from the bottom of the log up. This is useful for preventing the log from splitting or splintering.
  • Boring: Using the tip of the bar to bore a hole into the log. This is useful for relieving tension and preventing pinching.

• Avoiding Pinching: Pinching occurs when the weight of the log closes the cut, trapping the bar. To avoid pinching, use wedges to keep the cut open, or use a combination of overbucking and underbucking.

Case Study: I once worked on a project where we were processing a large quantity of storm-damaged maple trees. The trees were lying in all sorts of awkward positions, making bucking a real challenge. By carefully assessing each log and using a combination of overbucking, underbucking, and boring techniques, we were able to safely and efficiently cut the trees into manageable firewood lengths. We also used wedges extensively to prevent pinching, which saved us a lot of time and frustration.

Data Point: A study by the U.S. Forest Service found that proper bucking techniques can reduce the risk of chainsaw accidents by as much as 30%. This highlights the importance of taking the time to plan your cuts and use appropriate techniques.

Tip 3: Master the Art of Splitting

Splitting firewood can be a physically demanding task, but with the right techniques and tools, it can be made much easier.

• Tool Selection: There are several options for splitting firewood, including:

  • Maul: A heavy, axe-like tool with a broad head designed for splitting.
  • Splitting Axe: Similar to a maul, but with a more wedge-shaped head.
  • Wedges: Steel or plastic wedges that are driven into the wood with a sledgehammer.
  • Hydraulic Log Splitter: A powered machine that uses hydraulic pressure to split logs.

• Wood Species: The ease of splitting varies greatly depending on the species of wood. Softwoods like pine and fir are generally easy to split, while hardwoods like oak and maple can be much more challenging.

• Technique: When using a maul or splitting axe, focus on using your body weight to generate power. Aim for the center of the log, and use a smooth, controlled swing.

• Dealing with Knots: Knots can make splitting difficult. Try splitting the log from the opposite end, or use wedges to split the knot itself.

• Hydraulic Log Splitters: If you’re processing a large quantity of firewood, a hydraulic log splitter can save you a lot of time and effort. Choose a splitter with sufficient tonnage for the size and type of wood you’re processing.

Personal Story: I used to dread splitting firewood. I would spend hours swinging a maul, struggling to split stubborn logs. Then, I invested in a hydraulic log splitter. The difference was incredible. I was able to split a much larger quantity of wood in a fraction of the time, and with far less effort. While it was an initial investment, the time and energy it saved me were well worth it.

Data Point: A study comparing manual splitting methods to hydraulic log splitters found that hydraulic splitters can increase splitting efficiency by as much as 80%. This is especially true for larger logs and tougher wood species.
