Alright, let’s dive into the world of the Stihl 056 AV and how to make the most of this classic chainsaw for optimal woodcutting. I’ll even share a quick win right off the bat: simply ensuring your chain is properly sharpened and tensioned can dramatically increase your cutting speed and reduce strain on the saw! It’s a small thing, but it makes a huge difference.

Introduction: Why the Stihl 056 AV Matters

In the world of wood processing, logging, and firewood preparation, the chainsaw is king. And among chainsaws, certain models stand out for their power, durability, and historical significance. The Stihl 056 AV is undoubtedly one of those models. While newer, more technologically advanced saws exist, the 056 AV remains a popular choice for many, especially those who appreciate its raw power and robust construction. Understanding its specifications and mastering woodcutting techniques with it is crucial for anyone serious about working with wood.

The Stihl 056 AV is more than just a tool; it’s a piece of history. It represents a time when chainsaws were built to last, with simple yet effective designs. Knowing how to properly operate and maintain this saw can save you money, increase your efficiency, and, most importantly, keep you safe.

Understanding Key Concepts

Before we delve into the specifics of the Stihl 056 AV, let’s clarify some fundamental concepts related to wood processing:

• Green Wood vs. Seasoned Wood: Green wood is freshly cut wood with a high moisture content (often above 50%). Seasoned wood, on the other hand, has been dried to reduce its moisture content (ideally below 20% for firewood). Green wood is heavier, harder to split, and burns poorly, producing more smoke. Seasoned wood is lighter, easier to split, and burns cleaner and more efficiently.

• Felling: The process of cutting down a standing tree.

• Bucking: Cutting a felled tree into shorter, manageable lengths.

• Limbing: Removing branches from a felled tree.

• Debarking: Removing the bark from a log. This can speed up the drying process and reduce the risk of insect infestation.

• Kerf: The width of the cut made by the chainsaw chain.

• Kickback: A dangerous phenomenon where the tip of the chainsaw bar contacts a solid object, causing the saw to abruptly kick back towards the operator.

• Bar Oil: A specialized oil used to lubricate the chainsaw bar and chain, reducing friction and wear.

• Two-Stroke Engine: The Stihl 056 AV uses a two-stroke engine, which requires a mixture of gasoline and oil.

Stihl 056 AV: A Deep Dive into the Specs

Let’s get down to the nitty-gritty. The Stihl 056 AV is a powerful saw, and understanding its specifications is essential for safe and effective operation. Keep in mind that specs can vary slightly depending on the exact year and model variation.

• Engine Displacement: Typically around 87cc (cubic centimeters). This large displacement is what gives the 056 AV its impressive power.
• Engine Power: Around 6 horsepower (4.5 kW).
• Weight (Powerhead Only): Approximately 16.3 lbs (7.4 kg). This is a heavy saw, so proper technique and physical conditioning are important.
• Guide Bar Length: Commonly used with bars ranging from 20″ to 36″. I’ve personally found a 28″ bar to be a good all-around choice for most tasks.
• Chain Pitch: Typically .404″ or 3/8″. The pitch refers to the distance between the rivets on the chain.
• Fuel Tank Capacity: Approximately 27 oz (0.8 liters).
• Oil Tank Capacity: Approximately 10 oz (0.3 liters).
• Fuel Mix Ratio: Usually 50:1 (gasoline to two-stroke oil). Always consult your owner’s manual for the correct ratio. Using the wrong ratio can damage the engine.
• Ignition System: Breaker points ignition system on older models, electronic ignition on later models.

Why These Specs Matter:

• Engine Displacement & Power: These figures directly relate to the saw’s cutting capacity. A larger displacement and higher power output allow the saw to handle larger diameter logs and tougher wood species.
• Weight: The weight of the saw affects fatigue and maneuverability. A heavier saw requires more strength and stamina to operate safely and efficiently.
• Guide Bar Length: The bar length determines the maximum diameter log you can cut. Choose a bar length appropriate for the size of the trees you’ll be felling or bucking.
• Chain Pitch: The chain pitch affects the cutting speed and smoothness. A larger pitch is generally used for larger saws and tougher wood.
• Fuel & Oil Capacity: These figures determine how long you can run the saw before needing to refuel or add oil.

5 Pro Tips for Optimal Woodcutting with the Stihl 056 AV

Now, let’s get to the heart of the matter: how to get the most out of your Stihl 056 AV. These five pro tips are based on my years of experience and are designed to improve your efficiency, safety, and overall woodcutting experience.

1. Mastering Chain Sharpening and Maintenance

This is, without a doubt, the most crucial aspect of chainsaw operation. A dull chain is not only inefficient but also dangerous. It requires more force to cut, increasing the risk of kickback and operator fatigue.

• Sharpening Frequency: I sharpen my chain after every few tanks of fuel, or whenever I notice a decrease in cutting performance. Don’t wait until the chain is completely dull.
• Sharpening Tools: A chainsaw file, a depth gauge tool, and a file guide are essential. I prefer using a round file with the correct diameter for my chain’s pitch.
• Sharpening Technique:
  • Secure the chainsaw bar in a vise.
  • Use the file guide to maintain the correct filing angle (typically 30 degrees).
  • File each tooth from the inside out, using smooth, consistent strokes.
  • Maintain a consistent file depth.
  • Check and adjust the depth gauges after every few sharpenings. The depth gauges control how much the chain bites into the wood.
• Chain Tension: Proper chain tension is also critical. The chain should be snug on the bar but still able to be pulled around by hand. Too loose, and the chain can derail. Too tight, and it can overheat and break. Adjust the tension according to the manufacturer’s instructions.
• Chain Lubrication: Always use high-quality bar oil. Check the oil level frequently and refill as needed. A properly lubricated chain will last longer and cut more efficiently. You’ll notice it not only when cutting, but the chain will be able to be pulled along the bar by hand much easier.

Case Study: The Difference a Sharp Chain Makes

I once spent an entire afternoon struggling to fell a large oak tree with a dull chain. The saw was bogging down, the cuts were ragged, and I was exhausted. After finally sharpening the chain, the difference was night and day. The saw sliced through the wood effortlessly, and I finished the job in a fraction of the time. This experience taught me the importance of regular chain maintenance.

2. Perfecting Felling Techniques

Felling a tree is a complex and potentially dangerous task. It requires careful planning, precise cuts, and a thorough understanding of tree behavior.

• Assess the Tree and Surroundings: Before making any cuts, carefully assess the tree’s lean, branch distribution, and any signs of weakness or decay. Also, identify any obstacles in the felling zone, such as power lines, buildings, or other trees.
• Plan Your Escape Route: Always plan a clear escape route at a 45-degree angle away from the direction of fall.
• Make the Notch Cut: The notch cut determines the direction of fall. It consists of two cuts: a top cut at a 45-degree angle and a bottom cut that meets the top cut to form a wedge. The depth of the notch should be about 1/5 to 1/3 of the tree’s diameter.
• Make the Back Cut: The back cut is made on the opposite side of the tree from the notch, slightly above the bottom of the notch. Leave a hinge of uncut wood to control the fall of the tree. The hinge should be about 1/10 of the tree’s diameter.
• Use Wedges: If the tree is leaning in the wrong direction or if there is a risk of it pinching the saw, use felling wedges to help guide the fall.
• Communicate: If you’re working with a team, communicate clearly and use hand signals to coordinate your actions.
• Clear the Area: Before the tree falls, shout a warning to alert anyone in the vicinity.

Data Point: Felling Accidents

According to the Occupational Safety and Health Administration (OSHA), felling trees is one of the most dangerous jobs in the logging industry. A significant percentage of accidents are caused by improper felling techniques. Taking the time to learn and practice safe felling procedures can dramatically reduce your risk of injury.

3. Optimizing Bucking and Limbing Techniques

Once the tree is on the ground, the next step is to buck it into manageable lengths and remove the branches.

• Bucking:
  • Support the Log: Before making any cuts, ensure that the log is properly supported to prevent it from pinching the saw. Use branches or other logs to prop up the log.
  • Cutting Techniques: Use different cutting techniques depending on the log’s position and the presence of tension or compression.
    • Overbucking: Cutting from the top down. Used when the log is supported from below.
    • Underbucking: Cutting from the bottom up. Used when the log is supported from above.
    • Boring Cut: Using the tip of the saw to bore into the log. Used to relieve tension before making a final cut. Use extreme caution when performing a boring cut, as it can increase the risk of kickback.
  • Cut Length: Determine the appropriate cut length based on your needs. For firewood, a common length is 16 inches, but this can vary depending on the size of your wood stove or fireplace.
• Limbing:
  • Work from the Base to the Tip: Start by removing the branches closest to the base of the tree and work your way towards the tip.
  • Cut on the Downstroke: Whenever possible, cut branches on the downstroke to avoid kickback.
  • Use a Stable Stance: Maintain a stable stance and keep both hands on the saw.
  • Be Aware of Springback: Be aware that branches can spring back after being cut, potentially causing injury.

Personal Experience: Learning from Mistakes

I once made the mistake of trying to buck a log that was not properly supported. As I made the cut, the log shifted, pinching the saw and causing it to kick back violently. Fortunately, I was not injured, but it was a close call. This experience taught me the importance of always ensuring that the log is properly supported before cutting.

4. Choosing the Right Wood and Understanding its Properties

Not all wood is created equal. Different species have different properties that affect their suitability for various purposes, such as firewood, construction, or woodworking.

• Hardwoods vs. Softwoods: Hardwoods (e.g., oak, maple, ash) are generally denser and burn longer than softwoods (e.g., pine, fir, spruce). Hardwoods are also more difficult to split.
• Density: The density of the wood affects its burning characteristics. Denser woods contain more energy per unit volume and burn longer.
• Moisture Content: As mentioned earlier, moisture content is a critical factor. Green wood is difficult to burn and produces a lot of smoke. Seasoned wood burns cleaner and more efficiently.
• Splitting Difficulty: Some wood species are easier to split than others. Straight-grained woods like ash and oak are generally easier to split than knotty woods like elm or maple.
• Rot Resistance: Some wood species are more resistant to rot than others. Rot-resistant woods like cedar and redwood are often used for outdoor applications.
