Stihl 038 AV Chainsaw Review (5 Rare Features You Didn’t Know)

The Stihl 038 AV. Just saying the name conjures images of sturdy German engineering and reliable performance. This chainsaw is a workhorse, a legend in its own right. But beyond its well-known power and durability, there are some hidden gems, features that set it apart and might even make you appreciate yours (or consider hunting one down) even more.

1. The Forgotten Oiler Adjustment Screw

This is feature number one and it is probably the most important. We all know that oiling is crucial for chainsaw health and performance. Insufficient oiling leads to premature chain wear, bar damage, and ultimately, a seized engine. Most chainsaws have a simple, easily accessible oiler adjustment screw. The Stihl 038 AV has that. But the “rare” part is that some early models (and even some later ones, depending on the region and specific production run) featured a second, less obvious oiler adjustment.

• Where to Find It: Look closely at the bottom of the saw, near the chain catcher. You might find a tiny, recessed screw. This secondary adjustment allows for even finer control over the oil flow, particularly useful when working with different wood types or in varying weather conditions. If you do not find it, don’t worry. It’s a rare feature.
• Why It Matters: Fine-tuning the oiler prevents over-oiling (which wastes oil and makes a mess) and under-oiling (which damages your equipment). This is especially important when cutting hardwoods like oak or maple, which require more lubrication than softwoods like pine.
• Actionable Tip: Before making any adjustments, clean the area around the screw thoroughly. Use a small screwdriver to make incremental changes, testing the oil flow after each adjustment. Observe the amount of oil being thrown off the chain as it runs. You want a consistent, even spray.

2. The Hidden Compression Release Valve (Maybe)

Not all Stihl 038 AV models have a compression release valve, but some do, particularly those sold in regions with stricter emissions regulations or those designed for higher altitude use. This valve makes starting the saw significantly easier, especially when cold.

• Where to Find It: Look on the cylinder head, usually near the spark plug. If your saw has a compression release, you’ll see a small button or lever.
• Why It Matters: A compression release valve reduces the amount of force needed to pull the starter cord. This is a lifesaver, especially on a saw as powerful as the 038 AV. It also reduces wear and tear on the starter mechanism.
• Actionable Tip: If your saw has a compression release, always use it when starting the saw cold. Press the button or lever before pulling the starter cord. Once the engine starts, the valve will automatically close.
• Case Study: I once helped a friend who was struggling to start his 038 AV. After several frustrating attempts, I noticed the compression release valve, which he hadn’t even realized was there. Once he used it, the saw started on the first pull. It’s amazing how much difference such a small feature can make.

3. The “AV” System: More Than Just Rubber Mounts

The “AV” in Stihl 038 AV stands for “Anti-Vibration.” While most people know that the saw has rubber mounts to isolate the engine from the handles, the system is actually more sophisticated than it appears. The 038 AV uses a multi-point anti-vibration system, with strategically placed rubber and steel springs designed to dampen vibrations across a wide range of frequencies.

• Why It Matters: Prolonged exposure to chainsaw vibration can lead to hand-arm vibration syndrome (HAVS), a debilitating condition that causes numbness, tingling, and pain in the hands and fingers. A well-designed anti-vibration system significantly reduces the risk of HAVS.
• Unique Insight: The specific placement and type of anti-vibration elements in the 038 AV were carefully engineered to minimize vibration at the frequencies most likely to cause HAVS. This level of attention to detail is one of the reasons why the 038 AV is considered such a comfortable saw to use, even for extended periods.
• Actionable Tip: Regularly inspect the anti-vibration mounts for cracks or damage. Replace worn or damaged mounts immediately. Proper maintenance of the AV system is crucial for both comfort and safety.
• Data Point: Studies have shown that chainsaws with effective anti-vibration systems can reduce the risk of HAVS by as much as 50%.

4. The Interchangeable Sprocket System

The Stihl 038 AV features a modular sprocket system that allows you to easily change the sprocket to accommodate different chain pitches and gauges. This might seem like a minor detail, but it greatly increases the versatility of the saw.

• Why It Matters: Using the correct sprocket for your chain is essential for optimal performance and safety. Using the wrong sprocket can lead to chain slippage, premature wear, and even chain breakage.
• Unique Insight: Many users are unaware that they can easily switch between a standard .325″ pitch sprocket and a 3/8″ pitch sprocket. The 3/8″ pitch is better suited for larger timber and more aggressive cutting, while the .325″ pitch offers a smoother cut and is ideal for smaller jobs.
• Actionable Tip: Consult your owner’s manual to determine the correct sprocket for your chain. When changing the sprocket, be sure to use the correct tools and torque specifications.
• Cost Consideration: Sprockets are relatively inexpensive to replace. Having a spare sprocket on hand is a good idea, especially if you frequently switch between different chain types.

5. The “AV Super” Upgrade Potential

While the standard Stihl 038 AV is a powerful saw, it can be further upgraded to “AV Super” specifications. This involves replacing the cylinder and piston with those from the Stihl 038 Super model, resulting in a significant increase in power and torque.

• Why It Matters: The 038 Super is a more powerful version of the 038 AV, offering increased cutting speed and the ability to handle larger timber. Upgrading your 038 AV to Super specs gives you the best of both worlds: the reliability and durability of the 038 AV with the added power of the 038 Super.
• Unique Insight: The 038 AV and 038 Super share many of the same components, making the upgrade relatively straightforward. However, it’s important to note that the upgrade is not recommended for inexperienced users.
• Actionable Tip: If you’re considering upgrading your 038 AV to Super specs, consult with a qualified chainsaw technician. They can advise you on the best parts to use and ensure that the upgrade is done correctly.
• Cost Consideration: The cost of the upgrade will depend on the availability of parts and the labor costs of the technician. However, it’s generally a cost-effective way to increase the performance of your 038 AV.

Beyond the Features: Mastering Wood Processing

Now that we’ve explored the hidden gems of the Stihl 038 AV, let’s delve into the broader world of wood processing. Whether you’re felling trees for timber, preparing firewood for winter, or crafting woodworking projects, a solid understanding of wood processing techniques is essential.

Understanding Wood Properties: Green vs. Seasoned

The first step in any wood processing project is understanding the properties of wood itself. The most important distinction is between green wood and seasoned wood.

• Green Wood: This is freshly cut wood that still contains a high moisture content. Green wood is easier to split but more difficult to burn. It’s also more prone to warping and cracking as it dries.
• Seasoned Wood: This is wood that has been allowed to dry for a period of time, typically six months to two years. Seasoned wood burns hotter and cleaner than green wood. It’s also more stable and less likely to warp or crack.
• Data Point: The ideal moisture content for firewood is between 15% and 20%. Using a moisture meter is the best way to determine if your firewood is properly seasoned.
• Actionable Tip: Always season your firewood before burning it. This will not only improve the efficiency of your fire but also reduce the risk of creosote buildup in your chimney.

Essential Tools for Wood Processing

While the chainsaw is arguably the most important tool for wood processing, it’s just one piece of the puzzle. Here’s a rundown of some other essential tools:

• Axes: Axes are used for splitting wood, felling small trees, and limbing branches. There are two main types of axes: splitting axes and felling axes. Splitting axes have a wider, heavier head designed for splitting wood along the grain. Felling axes have a thinner, sharper head designed for cutting across the grain.
• Mauls: Mauls are similar to splitting axes but have a heavier head and a shorter handle. They are used for splitting large, knotty logs.
• Wedges: Wedges are used to split logs that are too large or too knotty to split with an axe or maul alone. They are driven into the log with a sledgehammer.
• Sledgehammers: Sledgehammers are used to drive wedges into logs and to split stubborn pieces of wood.
• Peaveys and Cant Hooks: These tools are used to roll and move logs. They are essential for handling large logs safely and efficiently.
• Chainsaw Safety Gear: This includes a helmet, eye protection, hearing protection, chainsaw chaps, and gloves. Never operate a chainsaw without wearing the proper safety gear.
• Moisture Meter: A moisture meter is used to measure the moisture content of wood. This is essential for determining if firewood is properly seasoned.

Chainsaws vs. Axes: A Head-to-Head Comparison

The age-old debate: chainsaw or axe? The answer, of course, depends on the task at hand.

• Chainsaws: Chainsaws are faster and more efficient for felling trees, bucking logs, and cutting large amounts of firewood. However, they require more maintenance and are more dangerous to operate.
• Axes: Axes are more versatile and require less maintenance than chainsaws. They are also quieter and do not require fuel. However, they are slower and more physically demanding to use.
• My Experience: I’ve always preferred using a chainsaw for felling trees and bucking logs, as it’s simply faster and more efficient. However, I still use an axe for splitting wood and limbing branches, as it gives me more control and allows me to work in tight spaces.
• Actionable Tip: Consider the size and scope of your project when choosing between a chainsaw and an axe. For large projects, a chainsaw is the clear choice. For smaller projects, an axe may be sufficient.

Safe Tree Felling Techniques

Felling trees is one of the most dangerous aspects of wood processing. It’s essential to use safe techniques and to be aware of your surroundings at all times.

1. Assess the Tree: Before felling a tree, assess its size, shape, and lean. Look for any signs of decay or damage. Also, check for any overhead hazards, such as dead branches or power lines.
2. Plan Your Escape Route: Before making any cuts, plan your escape route. This should be a clear path away from the tree, at a 45-degree angle to the direction of the fall.
3. Clear the Area: Clear the area around the tree of any obstacles, such as brush, rocks, or other trees.
4. Make the Notch Cut: The notch cut is a wedge-shaped cut that determines the direction of the fall. The notch should be about one-third of the tree’s diameter.
5. Make the Back Cut: The back cut is made on the opposite side of the tree from the notch cut. It should be slightly higher than the notch cut and should leave a hinge of wood to control the fall.
6. Warn Others: Before making the final cut, warn anyone in the area that the tree is about to fall.
7. Retreat Quickly: Once the tree starts to fall, retreat quickly along your escape route.
8. Case Study: I once witnessed a logger who was seriously injured when a tree fell in an unexpected direction. He had failed to properly assess the tree’s lean and had not planned an adequate escape route. This incident serves as a stark reminder of the importance of following safe tree felling techniques.
9. Actionable Tip: Never fell a tree alone. Always have a spotter who can warn you of any hazards.
10. Data Point: According to the Occupational Safety and Health Administration (OSHA), logging is one of the most dangerous occupations in the United States.

De-Limbing Procedures

De-limbing is the process of removing branches from a felled tree. It’s important to de-limb trees safely and efficiently to prevent injuries.

1. Wear Safety Gear: Always wear the proper safety gear when de-limbing trees. This includes a helmet, eye protection, hearing protection, chainsaw chaps, and gloves.
2. Work from the Butt to the Top: Start de-limbing at the butt of the tree and work your way to the top. This will prevent you from being trapped under falling branches.
3. Use a Sawhorse: Use a sawhorse to support the tree while you’re de-limbing it. This will make it easier to cut the branches and will prevent the tree from rolling.
4. Cut on the Opposite Side: When cutting a branch, cut on the opposite side of the tree from where you’re standing. This will prevent the branch from kicking back and hitting you.
5. Be Aware of Tension: Be aware of tension in the branches. Branches that are under tension can snap back violently when cut.
6. Actionable Tip: Use a de-limbing tool, such as a hook or a saw, to pull branches away from the tree. This will reduce the risk of injury.

Splitting Logs: Techniques and Tips

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

1. Choose the Right Tool: Choose the right tool for the job. For small logs, an axe may be sufficient. For larger logs, a maul or a hydraulic log splitter may be necessary.
2. Find a Stable Base: Find a stable base for splitting the logs. A large stump or a log splitting block works well.
3. Position the Log: Position the log so that the grain is running vertically. This will make it easier to split.
4. Swing with Power: Swing the axe or maul with power and accuracy. Aim for the center of the log.
5. Use Wedges: If the log is too tough to split with an axe or maul alone, use wedges. Drive the wedges into the log with a sledgehammer.
6. Hydraulic Log Splitters: If you have a lot of wood to split, consider investing in a hydraulic log splitter. These machines are much faster and easier to use than axes or mauls.
7. My Preferred Method: I prefer using a maul and wedges for splitting logs. It’s more physically demanding than using a hydraulic log splitter, but I find it to be more satisfying.
8. Actionable Tip: Sharpen your axe or maul regularly. A sharp tool is safer and more efficient to use.

Stacking and Seasoning Firewood: The Art of Drying

Properly stacking and seasoning firewood is crucial for ensuring that it burns efficiently and cleanly.

1. Choose a Sunny and Windy Location: Choose a location that is sunny and windy. This will help the wood dry faster.
2. Elevate the Wood: Elevate the wood off the ground. This will prevent it from absorbing moisture from the soil.
3. Stack Loosely: Stack the wood loosely, allowing for air circulation.
4. Cover the Top: Cover the top of the stack with a tarp or a sheet of metal. This will protect the wood from rain and snow.
5. Allow Adequate Time: Allow the wood to season for at least six months, and preferably longer.
6. The “Rule of Thumb”: A good rule of thumb is to stack your firewood in the spring for burning the following winter.
7. My Stacking Method: I stack my firewood in long rows, with the bark facing up. I leave a space between each row to allow for air circulation. I also cover the top of the stack with a tarp to protect it from the rain.
8. Actionable Tip: Use a moisture meter to check the moisture content of your firewood. The ideal moisture content for firewood is between 15% and 20%.

Costs, Budgeting, and Resource Management

Wood processing can be an expensive undertaking, especially if you’re starting from scratch. Here are some tips for managing costs and resources:
