Stihl 011 AVT Chainsaw Guide: 5 Pro Tips for Wood Processing

The Stihl 011 AVT is a classic, a workhorse of a chainsaw that, when properly maintained and used, can make wood processing a breeze. This guide isn’t just about using the saw; it’s about understanding its capabilities and limitations, and then applying that knowledge to get the most out of it. I’ll cover everything from chain maintenance to cutting techniques, all with the goal of helping you work smarter, not harder.

1. Mastering Chain Maintenance: The Key to Efficient Cutting

A dull chain is your worst enemy. It wastes fuel, puts unnecessary strain on the saw, and drastically increases the risk of kickback. I learned this the hard way years ago, trying to fell a seasoned oak with a chain that hadn’t seen a file in months. The saw bucked and vibrated, making the whole experience terrifying and inefficient.

Sharpening Your Chain Like a Pro

• Understanding the Anatomy: Before you even touch a file, know your chain. Identify the cutter type (chisel, semi-chisel, etc.) and the depth gauge setting. The Stihl 011 AVT typically uses a .325″ pitch chain, but always double-check the markings on your chain or the saw’s guide bar.
• Choosing the Right File: Use a round file that matches the pitch of your chain. For a .325″ pitch chain, a 5/32″ file is usually the correct size. Also, invest in a flat file and a depth gauge tool to maintain the correct depth gauge setting.
• The Sharpening Angle: This is crucial. Stihl chains typically require a sharpening angle of 30 degrees. Use a file guide to maintain this angle consistently. Consistency is key.
• The Filing Process: Secure the chainsaw bar in a vise. File each cutter with smooth, even strokes, working from the inside of the cutter outwards. Aim for three to five strokes per cutter, removing any nicks or burrs.
• Depth Gauge Maintenance: Use the flat file and depth gauge tool to lower the depth gauges as needed. The depth gauge should be approximately 0.025″ below the top of the cutter. This measurement is critical for preventing kickback.
• Data Point: According to Stihl’s technical data, a properly sharpened chain can reduce cutting time by up to 20% and fuel consumption by 10%.

Tensioning Your Chain Correctly

• Why Tension Matters: Proper chain tension prevents the chain from derailing and ensures smooth, efficient cutting. Too loose, and the chain can jump off the bar; too tight, and it can overheat and break.
• The “Pull and Release” Method: With the saw turned off, lift the chain in the middle of the guide bar. You should be able to pull the chain out about 1/8″ to 1/4″. If it pulls out more, tighten the tension; if it barely moves, loosen it.
• Adjusting the Tension: Use the tensioning screw on the side of the saw to adjust the chain tension. Tighten the screw to increase tension, and loosen it to decrease tension.
• Hot vs. Cold Tension: Remember that the chain will expand as it heats up during use. Adjust the tension slightly looser when the chain is cold, as it will tighten up as it warms up.
• Case Study: In a project where I was cutting firewood for a winter, I noticed that my chain was constantly loosening. After inspecting the bar, I found that it was worn, causing the chain to stretch more than usual. Replacing the bar solved the problem and improved cutting efficiency significantly.

Chain Lubrication: Extending Chain and Bar Life

• The Importance of Oil: Chain oil reduces friction between the chain and the bar, preventing overheating and wear. Always use a high-quality bar and chain oil.
• Checking the Oil Level: Before each use, check the oil level in the oil tank. Refill as needed.
• Oil Flow Adjustment: The Stihl 011 AVT has an adjustable oil pump. Adjust the oil flow based on the type of wood you’re cutting. Hardwoods require more oil than softwoods.
• Visual Inspection: During use, periodically check the chain to ensure that it’s being properly lubricated. You should see a light spray of oil coming off the chain as it rotates.
• Data Point: Studies have shown that using the correct bar and chain oil can extend the life of your chain and bar by up to 50%.

2. Mastering Cutting Techniques: Felling, Limbing, and Bucking

Knowing how to cut wood safely and efficiently is paramount. I once witnessed a near-miss accident when a fellow firewood cutter improperly felled a tree, causing it to fall in an unexpected direction. It was a stark reminder of the importance of proper technique.

Felling Techniques: Bringing Trees Down Safely

• Planning Your Fall: Before you even start your saw, assess the tree and its surroundings. Identify the lean of the tree, the wind direction, and any obstacles that could affect its fall.
• The Hinge: The hinge is the most critical part of the felling process. It controls the direction of the fall. Cut a notch on the side of the tree facing the direction you want it to fall, typically at a 45-degree angle.
• The Back Cut: Make the back cut slightly above the bottom of the notch, leaving a hinge of about 10% of the tree’s diameter. Never cut completely through the tree.
• Using Felling Wedges: If the tree doesn’t start to fall on its own, use felling wedges to help push it over. Insert the wedges into the back cut and hammer them in.
• Escape Route: Always have a clear escape route planned before you start cutting.
• Safety Code: OSHA regulations require a minimum distance of two tree lengths between workers during felling operations.

Limbing Techniques: Removing Branches Safely

• Working from the Base Up: Start limbing from the base of the tree and work your way up towards the top. This prevents branches from falling on you.
• Cutting on the Opposite Side: When limbing, cut on the opposite side of the branch from where you’re standing. This minimizes the risk of kickback.
• Supporting Branches: If a branch is under tension, make a relief cut on the underside of the branch before cutting it completely through. This prevents the branch from pinching the saw.
• Using a Sawhorse: For smaller branches, use a sawhorse to support the branch while you’re cutting it. This makes the job easier and safer.
• Personal Story: I once tried to limb a large branch that was under significant tension without making a relief cut. The branch snapped back violently, nearly hitting me. It taught me a valuable lesson about respecting the forces at play when working with wood.

Bucking Techniques: Cutting Logs into Manageable Lengths

• Planning Your Cuts: Before you start bucking, plan your cuts to minimize waste and maximize efficiency. Consider the size and shape of the logs, and the intended use of the wood.
• Supporting the Log: Support the log so that it doesn’t pinch the saw. Use logs or wedges to elevate the log off the ground.
• Cutting from the Top: If the log is supported at both ends, cut from the top. If it’s supported in the middle, cut from the bottom.
• The “Kerf Test”: Before making a complete cut, make a small kerf (a shallow cut) on the opposite side of the log. This helps prevent the wood from splitting or pinching the saw.
• Log Dimensions: Firewood logs typically range from 12 to 24 inches in length, depending on the size of your stove or fireplace. Standard cord dimensions are 4 feet high, 4 feet wide, and 8 feet long, totaling 128 cubic feet.

3. Understanding Wood Properties: Hardwoods vs. Softwoods

Knowing the difference between hardwoods and softwoods is crucial for selecting the right wood for your needs and for adjusting your cutting techniques accordingly. I once made the mistake of trying to split a seasoned oak log with a maul that was too light. After hours of struggling, I realized that I needed a heavier maul and a better understanding of the wood’s properties.

Hardwoods: Dense and Durable

• Characteristics: Hardwoods are typically denser and more durable than softwoods. They burn hotter and longer, making them ideal for firewood.
• Examples: Oak, maple, ash, birch, and cherry are all examples of hardwoods.
• Cutting Considerations: Hardwoods are more difficult to cut than softwoods. They require a sharper chain and more power.
• Splitting Considerations: Hardwoods are also more difficult to split than softwoods. They often require a hydraulic log splitter or a heavy maul.
• Data Point: Oak has a density of approximately 0.75 g/cm³, while pine has a density of approximately 0.45 g/cm³. This difference in density affects both cutting and splitting.

Softwoods: Light and Easy to Work With

• Characteristics: Softwoods are typically lighter and easier to work with than hardwoods. They ignite easily and burn quickly, making them ideal for kindling.
• Examples: Pine, fir, spruce, and cedar are all examples of softwoods.
• Cutting Considerations: Softwoods are easier to cut than hardwoods. They require less power and a less aggressive chain.
• Splitting Considerations: Softwoods are also easier to split than hardwoods. They can often be split with a hatchet or a light maul.
• Material Specifications: Softwoods typically have a higher resin content than hardwoods, which can cause them to smoke more when burned.

Wood Moisture Content: The Key to Efficient Burning

• Why Moisture Matters: Wet wood is difficult to ignite, produces less heat, and creates more smoke and creosote. Seasoning wood (drying it) reduces its moisture content, making it burn more efficiently.
• Measuring Moisture Content: Use a moisture meter to measure the moisture content of your wood. A moisture meter measures the electrical resistance of the wood, which is directly related to its moisture content.
• Ideal Moisture Content: The ideal moisture content for firewood is between 15% and 20%.
• Seasoning Process: Seasoning wood involves stacking it in a well-ventilated area and allowing it to dry for several months. The length of time required for seasoning depends on the type of wood and the climate.
• Data Point: According to the Forest Products Laboratory, it takes approximately six to twelve months to season hardwoods and three to six months to season softwoods.
• Drying Tolerances: Wood shrinks as it dries, which can cause it to crack or split. This is a natural process and does not affect the wood’s burning properties.

4. Safety First: Protecting Yourself and Others

Chainsaw safety is non-negotiable. I’ve seen too many injuries caused by carelessness or ignorance. Always wear appropriate safety gear and follow safe operating procedures.

Essential Safety Gear: Protecting Your Body

• Helmet: Protects your head from falling branches and kickback.
• Eye Protection: Protects your eyes from flying debris. Safety glasses or a face shield are essential.
• Hearing Protection: Protects your ears from the loud noise of the chainsaw. Earplugs or earmuffs are recommended.
• Gloves: Protect your hands from cuts and abrasions.
• Chainsaw Chaps: Protect your legs from chainsaw cuts. Chaps are made of ballistic nylon or Kevlar and are designed to stop the chain instantly.
• Steel-Toed Boots: Protect your feet from falling logs and chainsaw cuts.
• Visual Example: A diagram showing the correct placement of safety gear, including the helmet, eye protection, hearing protection, gloves, chaps, and boots.

Safe Operating Procedures: Preventing Accidents

• Read the Manual: Before using your chainsaw, read the owner’s manual carefully. Understand the saw’s features, limitations, and safety precautions.
• Inspect the Saw: Before each use, inspect the saw for any damage or defects. Check the chain tension, oil level, and fuel level.
• Clear the Work Area: Clear the work area of any obstacles, such as rocks, branches, and people.
• Maintain a Firm Grip: Always maintain a firm grip on the saw with both hands. Keep your thumbs wrapped around the handles.
• Avoid Overreaching: Avoid overreaching or cutting above shoulder height.
• Be Aware of Kickback: Kickback is the sudden, uncontrolled movement of the saw bar back towards the operator. It can cause serious injury. To prevent kickback, avoid cutting with the upper quadrant of the bar tip.
• Never Cut Alone: Always work with a partner or let someone know where you’ll be and when you expect to return.
• Emergency Plan: Have an emergency plan in place in case of an accident. Know how to contact emergency services and how to administer first aid.
• Industry Standards: Adhere to ANSI Z133 standards for tree care operations.
