Stihl 056 AV: Classic Logging Power (5 Surprising Facts)

The Stihl 056 AV isn’t just a chainsaw; it’s a piece of logging history. Its reputation precedes it, and for good reason. This saw was a workhorse for professionals, known for its power and reliability in the toughest conditions. But beyond the basic specs, there are some lesser-known facts that truly highlight its significance.

A Powerhouse Engine: More Than Meets the Eye

When you first lay eyes on the Stihl 056 AV, the first thing that strikes you is its size and heft. This isn’t a dainty little limbing saw. This is a serious piece of machinery designed to fell big trees. The engine, typically a 87cc or 93cc two-stroke, is the heart of this beast.

• Displacement and Power: The 056 AV came in a couple of different engine sizes, but the most common were the 87cc and 93cc versions. The 87cc model produced around 6 horsepower, while the 93cc variant could crank out closer to 6.5 horsepower. This might not sound like much compared to modern saws, but the power delivery was incredibly torquey, meaning it could pull through tough wood without bogging down.

• Torque Curve: Unlike modern high-revving saws, the 056 AV was all about low-end grunt. The torque curve was relatively flat, providing consistent power throughout the RPM range. This made it ideal for felling large-diameter trees where sustained cutting power was essential.

• Fuel Consumption: Let’s be honest, fuel efficiency wasn’t the 056 AV’s strong suit. These saws were known for being thirsty, especially when working hard. Expect to burn through a tank of fuel fairly quickly, especially with the larger 93cc engine. It’s a trade-off for the raw power it delivers.

My Experience: I remember one time I was helping a friend clear some storm-damaged timber from his property. He had a modern, high-tech saw, and I brought along my trusty 056 AV. While his saw was lighter and easier to handle, when it came to bucking up a massive oak log, the 056 AV just chewed right through it without a fuss. He was impressed by the sheer power of that old saw.

The Anti-Vibration System: A Game Changer for Its Time

The “AV” in Stihl 056 AV stands for “Anti-Vibration.” Now, anti-vibration systems are commonplace in modern chainsaws, but back in the 1970s when the 056 AV was introduced, it was a revolutionary feature.

• Isolation Technology: The 056 AV’s anti-vibration system used a series of rubber mounts to isolate the engine and cutting components from the handles. This significantly reduced the amount of vibration transferred to the operator, making it much more comfortable to use for extended periods.

• Reduced Fatigue: By minimizing vibration, the anti-vibration system helped reduce operator fatigue, which in turn improved safety and productivity. Loggers could work longer and more efficiently without their hands and arms going numb.

• Long-Term Health Benefits: Prolonged exposure to chainsaw vibration can lead to a condition called “vibration white finger” (VWF), a painful and debilitating condition that affects blood circulation in the fingers. The 056 AV’s anti-vibration system helped mitigate this risk, contributing to the long-term health and well-being of professional loggers.

Data Point: Studies have shown that effective anti-vibration systems can reduce vibration exposure by as much as 70-80%, significantly lowering the risk of VWF and other vibration-related injuries.

Unique Insight: While the 056 AV’s anti-vibration system was groundbreaking for its time, it’s worth noting that modern anti-vibration technology has come a long way. Newer saws often use more sophisticated systems with multiple layers of isolation and dampening materials.

The “West Coast” Conversion: A Nod to Logging Heritage

The Stihl 056 AV gained a cult following, particularly on the West Coast of North America. Loggers in this region often modified their 056 AVs to better suit the demands of felling massive redwood and Douglas fir trees.

• Aftermarket Parts: A whole industry sprung up around aftermarket parts for the 056 AV, including larger carburetors, ported cylinders, and modified mufflers. These modifications were designed to boost power and performance, allowing the saws to handle even the most challenging cutting tasks.

• The “West Coast” Muffler: One of the most popular modifications was the “West Coast” muffler, which featured a larger exhaust outlet and a more open design. This allowed the engine to breathe more freely, resulting in increased horsepower and a more aggressive sound.

• Chain and Bar Upgrades: West Coast loggers also favored longer bars and more aggressive chain types to maximize cutting speed and efficiency. Bars ranging from 32 to 36 inches were common, and chains with full-chisel cutters were preferred for their aggressive cutting action.

Case Study: I once met an old-timer who had been logging in the Pacific Northwest for over 40 years. He swore by his modified 056 AV, claiming it could out-cut any modern saw in a big-timber environment. He had fitted it with a West Coast muffler, a ported cylinder, and a 36-inch bar, and he said it was the perfect tool for felling giant redwoods.

Personalized Storytelling: I remember seeing one of these modified 056 AVs in action. The sound was incredible – a deep, throaty roar that echoed through the forest. It was like listening to a finely tuned racing engine. The saw just seemed to glide through the wood, effortlessly felling trees that would have challenged lesser machines.

Interchangeability and Adaptability: A Modular Masterpiece

One of the most surprising and often overlooked aspects of the Stihl 056 AV is its modular design and the high degree of interchangeability between different models and versions.

• Parts Compatibility: Many parts from different 056 AV variants, as well as some parts from other Stihl saws of the same era, are interchangeable. This makes it relatively easy to find replacement parts and keep these saws running, even decades after they were discontinued.

• Engine Swaps: It’s not uncommon to find 056 AVs with swapped engines or cylinders. For example, some people have replaced the 87cc engine with the more powerful 93cc version, or vice versa, depending on their specific needs.

• Customization Options: The modular design also lends itself to customization. Owners can easily swap out components like the carburetor, muffler, or ignition system to fine-tune the saw’s performance to their liking.

Practical Insights: This interchangeability is a huge advantage for hobbyists and small logging operations. It means that you don’t necessarily have to buy a brand new saw if a part breaks. You can often find used parts or even cannibalize parts from another saw to keep your 056 AV running.

Actionable Takeaways: If you own a Stihl 056 AV, it’s worth familiarizing yourself with the parts diagrams and compatibility charts. This will make it much easier to troubleshoot problems and find replacement parts when needed.

The “Super” Designation: Unlocking Hidden Potential

The Stihl 056 AV was eventually superseded by the Stihl 056 Super. While the two saws look very similar, the 056 Super offered some significant improvements in terms of power and performance.

• Larger Cylinder and Piston: The 056 Super featured a larger cylinder and piston, resulting in increased displacement and horsepower. The exact displacement varied depending on the specific model, but it was typically around 93cc or 94cc.

• Improved Porting: The cylinder on the 056 Super also had improved porting, which allowed for better airflow and more efficient combustion. This resulted in a noticeable increase in power and torque.

• Different Carburetor: The 056 Super used a different carburetor than the standard 056 AV, which was designed to handle the increased fuel demands of the larger engine.

Detailed Analysis: The 056 Super was essentially a “hot-rodded” version of the standard 056 AV. It offered a significant performance boost, making it even more capable of handling large-diameter trees and demanding cutting tasks.

Real Examples: Many loggers who had previously used the standard 056 AV switched to the 056 Super as soon as it became available. They reported that the Super version had noticeably more power and could cut through wood much faster.

Key Components: The key differences between the 056 AV and the 056 Super are the cylinder, piston, carburetor, and porting. If you’re looking to upgrade your 056 AV, swapping out these components with those from a 056 Super can significantly improve its performance.

Wood Processing with the Stihl 056 AV: A Practical Guide

Now that we’ve explored some of the surprising facts about the Stihl 056 AV, let’s talk about how to use it effectively for wood processing. Whether you’re felling trees, bucking logs, or preparing firewood, the 056 AV can be a valuable tool, but it’s important to use it safely and efficiently.

Felling Techniques: Mastering the Art of Tree Falling

Felling trees is one of the most dangerous tasks in wood processing, so it’s crucial to have a solid understanding of felling techniques and safety procedures.

• Planning is Key: Before you even start your saw, take the time to assess the tree and its surroundings. Look for any hazards, such as dead limbs, power lines, or other trees that could be affected by the falling tree. Determine the tree’s lean, wind direction, and any other factors that could influence its fall.

• The Notch: The notch is a critical component of the felling process. It’s a wedge-shaped cut that determines the direction the tree will fall. The notch should be cut on the side of the tree that you want it to fall towards, and it should be deep enough to guide the tree accurately.

• The Back Cut: The back cut is made on the opposite side of the tree from the notch. It should be cut slightly higher than the notch and should leave a hinge of wood to control the tree’s fall.

• Safety First: Always wear appropriate safety gear when felling trees, including a hard hat, eye protection, hearing protection, and chainsaw chaps. Be aware of your surroundings and have a clear escape route planned in case the tree doesn’t fall as expected.

Safety Standards: OSHA (Occupational Safety and Health Administration) has specific regulations for tree felling, including requirements for training, personal protective equipment, and safe work practices. It’s important to be familiar with these regulations and follow them carefully.

Real Examples: I once witnessed a logger who failed to properly assess the lean of a tree before felling it. As a result, the tree fell in the wrong direction and narrowly missed hitting a nearby power line. It was a close call that could have had serious consequences.

Actionable Takeaways: Always take the time to plan your felling operations carefully and follow established safety procedures. Don’t rush the process, and always prioritize safety over speed.

Bucking and Limbing: Turning Trees into Usable Logs

Once a tree has been felled, the next step is to buck it into logs of the desired length and to remove any limbs.

• Bucking Techniques: Bucking involves cutting the tree trunk into shorter sections. When bucking, it’s important to support the log to prevent it from pinching the saw blade. Use wedges or other supports to keep the log from rolling or shifting while you’re cutting.

• Limbing Techniques: Limbing involves removing the branches from the tree trunk. When limbing, always work from the base of the tree towards the top, and be careful to avoid kickback. Use a firm grip on the saw and keep your body out of the path of the blade.

• Chain Maintenance: Keeping your chainsaw chain sharp is essential for efficient bucking and limbing. A dull chain will require more effort to cut through the wood and will increase the risk of kickback. Sharpen your chain regularly and inspect it for damage.

Data Points: Studies have shown that a sharp chainsaw chain can increase cutting speed by as much as 50% and reduce fuel consumption by up to 20%.

Unique Insights: When bucking large-diameter logs, it’s often helpful to use a technique called “plunge cutting.” This involves inserting the tip of the saw blade into the log and cutting from the inside out. Plunge cutting can help prevent pinching and make it easier to control the cut.

Challenges Faced by Hobbyists: Many hobbyists struggle with bucking and limbing because they lack the proper equipment and training. It’s important to invest in quality tools and to learn proper techniques from experienced professionals.

Firewood Preparation: From Logs to Burnable Fuel

Preparing firewood is a common application for the Stihl 056 AV. Whether you’re heating your home with wood or simply enjoying a campfire, the 056 AV can help you turn logs into burnable fuel.
