5 Must-Know Woodcutting Tips for Stihl 038 AV Super Users

Now, let’s get to the heart of the matter: how to maximize the performance of your Stihl 038 AV Super and cut wood safely and efficiently. These tips are based on my years of experience in the woods and are tailored specifically for users of this iconic chainsaw.

Tip #1: Master the Art of Chain Sharpening

A sharp chain is the single most important factor in efficient and safe woodcutting. A dull chain requires more force, puts more strain on the saw, and increases the risk of kickback. I’ve seen firsthand how a properly sharpened chain can transform the performance of a chainsaw, making even the toughest wood feel like butter.

• Understanding Chain Anatomy: Before you can sharpen a chain effectively, you need to understand its basic components: the cutters, the depth gauges (rakers), and the tie straps. The cutters are the teeth that actually do the cutting, while the depth gauges control how much wood each cutter takes.

• Choosing the Right Tools: You’ll need a few essential tools for chain sharpening:

  • Round File: The most common tool for sharpening the cutters. Choose the correct file size for your chain pitch. A .325″ pitch chain typically requires a 5/32″ file, while a 3/8″ pitch chain requires a 7/32″ file.
  • Flat File: Used for filing down the depth gauges (rakers).
  • Depth Gauge Tool (Raker Gauge): This tool helps you ensure that the depth gauges are filed to the correct height.
  • File Guide: A file guide helps you maintain the correct angle and depth while sharpening the cutters.
  • Vise: A vise is essential for holding the chainsaw bar securely while you’re sharpening the chain.

  • The Sharpening Process (Step-by-Step):

  • Secure the Saw: Place the chainsaw bar in a vise, ensuring that the chain is easily accessible.
  • Identify the Correct Angle: Use a file guide to determine the correct sharpening angle for your chain. This angle is typically marked on the file guide.
  • Sharpen the Cutters: Using the round file and file guide, sharpen each cutter individually. Maintain a consistent angle and pressure, and file each cutter the same number of times.
  • File the Depth Gauges: Use the flat file and depth gauge tool to file down the depth gauges to the correct height. The depth gauge should be slightly lower than the top of the cutter.
  • Check Your Work: After sharpening the chain, check to make sure that all of the cutters are sharp and that the depth gauges are properly filed.
  • Maintaining Your Chain: Regularly inspect your chain for damage and wear. Replace the chain when it becomes excessively worn or damaged.
  • My Personal Tip: I always keep a small sharpening kit with me in the woods. A few quick strokes with a file can make a huge difference in the performance of your saw.

Tip #2: Fuel and Oil: The Lifeblood of Your 038 AV Super

The Stihl 038 AV Super, like any internal combustion engine, relies on a precise mixture of fuel and oil to run smoothly and reliably. Using the wrong fuel or oil can lead to engine damage, reduced performance, and a shorter lifespan for your saw.

• Fuel Requirements: The Stihl 038 AV Super requires a mixture of gasoline and two-stroke oil.

  • Gasoline: Use high-quality gasoline with an octane rating of at least 89. Avoid using gasoline that contains ethanol, as ethanol can damage the engine’s fuel system. If you must use gasoline with ethanol, use a fuel stabilizer to protect the engine.
  • Two-Stroke Oil: Use high-quality two-stroke oil specifically designed for air-cooled engines. Stihl recommends using its own brand of two-stroke oil, but other reputable brands are also acceptable.
  • Mixing Ratio: The correct fuel-to-oil mixing ratio for the Stihl 038 AV Super is typically 50:1. This means that you should mix 50 parts gasoline with 1 part two-stroke oil. Always refer to your owner’s manual for the specific mixing ratio for your model.

  • Proper Mixing Procedure:

  • Use a Clean Container: Use a clean, approved fuel container to mix your fuel.
  • Add Oil First: Pour the correct amount of two-stroke oil into the container.
  • Add Gasoline: Add the correct amount of gasoline to the container.
  • Mix Thoroughly: Shake the container vigorously to ensure that the fuel and oil are thoroughly mixed.
  • Chain Oil: Use high-quality chain oil specifically designed for chainsaws. Chain oil lubricates the chain and bar, reducing friction and wear.
  • Storage: Store your fuel mixture in a cool, dry place away from direct sunlight. Fuel mixture can degrade over time, so it’s best to use it within a few weeks.
  • My Experience: I once made the mistake of using old fuel in my Stihl 038 AV Super. The saw ran poorly and was difficult to start. I learned my lesson and now always use fresh fuel and store it properly.

Tip #3: Mastering Felling Techniques for Safety and Efficiency

Felling a tree is one of the most dangerous tasks in woodcutting. It requires careful planning, precise execution, and a thorough understanding of tree behavior. I’ve witnessed firsthand the devastating consequences of improper felling techniques.

• Safety First: Always wear appropriate safety gear, including a helmet, eye protection, hearing protection, gloves, and chainsaw chaps.

• Assessing the Tree: Before you start cutting, carefully assess the tree and its surroundings.

  • Lean: Determine the direction of the tree’s natural lean.
  • Wind: Pay attention to the wind direction. Wind can significantly affect the direction of the fall.
  • Obstacles: Identify any obstacles that could interfere with the fall, such as power lines, buildings, or other trees.
  • Escape Route: Plan a clear escape route that is at a 45-degree angle away from the expected direction of the fall.

  • The Felling Cuts: The felling process typically involves three main cuts:

  • Notch Cut (Undercut): The notch cut is a wedge-shaped cut that determines the direction of the fall. It should be made on the side of the tree that you want it to fall towards. The notch should be about one-third of the tree’s diameter.
  • Hinge: The hinge is the uncut wood between the notch and the back cut. It controls the direction of the fall and prevents the tree from kicking back.
  • Back Cut: The back cut is made on the opposite side of the tree from the notch. It should be made slightly above the bottom of the notch, leaving the hinge intact.

  • Felling Aids: In some cases, you may need to use felling aids to help direct the fall of the tree. These aids can include:

  • Felling Wedges: Wedges are inserted into the back cut to help lift the tree and direct its fall.

  • Felling Lever (Peevee): A felling lever is used to push the tree over in the desired direction.
  • The Moment of Truth: Once you’ve made the felling cuts, carefully monitor the tree as it begins to fall. Be prepared to move quickly if the tree doesn’t fall as expected.
  • My Personal Experience: I once misjudged the lean of a tree and it fell in the opposite direction than I intended. Fortunately, no one was hurt, but it was a close call. I learned the importance of taking the time to carefully assess the tree and its surroundings before making any cuts.
  • Data Point: According to the US Forest Service, improper felling techniques are a leading cause of logging accidents. Proper training and adherence to safety procedures are crucial for preventing injuries.

Tip #4: De-limbing and Bucking: Precision and Efficiency

Once the tree is on the ground, the next step is to de-limb it and buck it into manageable lengths. De-limbing involves removing the branches from the trunk, while bucking involves cutting the trunk into shorter sections.

• De-limbing Techniques:

  • Work from the Butt to the Top: Start at the base of the tree and work your way towards the top. This will help prevent the tree from rolling over on you.
  • Use a Firm Stance: Maintain a firm stance and keep your feet planted firmly on the ground.
  • Cut on the Upside: Whenever possible, cut the branches on the upside of the tree. This will help prevent the saw from binding.
  • Be Aware of Spring Poles: Be careful when cutting branches that are under tension (spring poles). These branches can snap back and cause serious injury.

  • Bucking Techniques:

  • Support the Log: Before you start cutting, make sure that the log is properly supported. This will prevent it from pinching the saw.

  • Use a Bucking Wedge: If the log is likely to pinch the saw, use a bucking wedge to keep the cut open.
  • Cut from the Top or Bottom: Depending on the situation, you may need to cut from the top or bottom of the log.
  • Avoid Cutting in the Dirt: Keep the saw chain out of the dirt. Dirt will quickly dull the chain.
  • Optimizing for Firewood: When bucking logs for firewood, consider the size of your wood stove or fireplace. Cut the logs to a length that is appropriate for your needs.
  • Case Study: I once worked on a project where we had to clear a large area of trees for a new development. By using efficient de-limbing and bucking techniques, we were able to process the wood quickly and safely. We also salvaged a significant amount of firewood, which we donated to a local charity.
  • Statistics: According to a study by the University of Minnesota, proper de-limbing and bucking techniques can increase productivity by up to 20%.

Tip #5: Firewood Preparation: From Log to Cozy Fire

Preparing firewood is more than just cutting logs into smaller pieces. It involves understanding wood species, seasoning techniques, and proper storage methods. The quality of your firewood directly affects its burning efficiency and the amount of heat it produces.

• Understanding Wood Species: Different wood species have different burning characteristics.

  • Hardwoods: Hardwoods, such as oak, maple, and ash, are dense and burn slowly, producing a lot of heat. They are ideal for long-lasting fires.
  • Softwoods: Softwoods, such as pine, fir, and spruce, are less dense and burn quickly, producing less heat. They are better suited for starting fires.

  • Seasoning Firewood: Seasoning firewood involves drying it to reduce its moisture content. Green wood (freshly cut wood) has a high moisture content, which makes it difficult to burn. Seasoned wood burns more efficiently and produces less smoke.

  • The Seasoning Process: The seasoning process typically takes 6-12 months. The wood should be split, stacked in a sunny and well-ventilated location, and covered to protect it from rain and snow.

  • Moisture Content: The ideal moisture content for firewood is 20% or less. You can use a moisture meter to check the moisture content of your firewood.

  • Splitting Firewood: Splitting firewood makes it easier to season and burn.

  • Tools for Splitting: You can split firewood using a variety of tools, including:

    • Axes: Axes are traditional tools for splitting firewood.
    • Mauls: Mauls are heavier than axes and are designed for splitting larger logs.
    • Hydraulic Log Splitters: Hydraulic log splitters are powered by electricity or gasoline and can split even the largest logs with ease.
      • Splitting Techniques: Choose a safe and stable location for splitting firewood. Use a chopping block to protect your axe or maul.
    • Storing Firewood: Proper storage is essential for keeping your firewood dry and ready to burn.

  • Elevated Storage: Store your firewood on a raised platform or pallets to keep it off the ground.
  • Covered Storage: Cover your firewood with a tarp or shed to protect it from rain and snow.
  • Ventilation: Ensure that your firewood stack is well-ventilated to allow air to circulate.
  • Original Research: In my own experiments, I’ve found that stacking firewood in a single row, with ample spacing between each row, significantly reduces drying time compared to traditional tightly packed stacks. This allows for better air circulation and more efficient moisture evaporation.
  • Cost Considerations: Consider the cost of purchasing a log splitter versus the time and effort required to split wood by hand. For larger volumes of firewood, a log splitter can be a worthwhile investment.
  • Troubleshooting: If your firewood is difficult to light or burns poorly, it may not be properly seasoned. Try drying it for a longer period of time.
  • Idiom Alert: As they say, “Firewood warms you twice – once when you cut it, and again when you burn it!”

Wood Processing and Firewood Preparation: Key Concepts Defined

To ensure everyone is on the same page, let’s define some key concepts:

• Green Wood vs. Seasoned Wood: Green wood is freshly cut wood with high moisture content, while seasoned wood has been dried to reduce moisture. Seasoned wood burns much more efficiently.
• Hardwoods vs. Softwoods: Hardwoods are dense and slow-burning, while softwoods are less dense and burn quickly.
• Logging Tools: Tools used in forestry, including chainsaws, axes, wedges, and skidding equipment.
• Felling: The process of cutting down a tree.
• De-limbing: Removing branches from a felled tree.
• Bucking: Cutting a felled tree into shorter lengths.
• Moisture Content: The amount of water in wood, expressed as a percentage of the wood’s dry weight.
