Choosing the right bar length for your 038 Magnum is crucial for maximizing its power, efficiency, and safety.
I’ve spent countless hours in the woods, felling trees and processing firewood with my own Stihl 038 Magnum. I’ve learned firsthand the importance of matching the bar length to the task at hand and the type of wood I’m cutting. Through trial and error, and a lot of sawdust, I’ve developed a keen understanding of what works and what doesn’t.
In this guide, I’ll share my expertise and provide you with five expert tips for selecting the optimal bar size for your Stihl 038 Magnum. We’ll delve into the factors that influence bar selection, explore the pros and cons of different lengths, and discuss how to maintain your bar for peak performance.
Understanding the Stihl 038 Magnum: A Quick Overview
Before diving into bar selection, let’s briefly recap the Stihl 038 Magnum. This saw is a legend for a reason. It’s a powerful, durable workhorse renowned for its reliability and ability to handle demanding tasks. It’s a favorite among loggers, arborists, and serious firewood enthusiasts.
- Engine Displacement: Around 61.5 cc, providing ample power for various cutting applications.
- Weight: Approximately 15 pounds (without bar and chain), making it a manageable weight for extended use.
- Optimal Use: Felling medium-sized trees, bucking logs, and heavy-duty firewood processing.
The 038 Magnum’s robust engine delivers impressive torque, allowing it to pull a longer bar than many other saws in its class. However, that doesn’t mean you should always opt for the longest bar possible. The key is to strike a balance between cutting capacity and maneuverability.
Tip #1: Assess Your Cutting Needs
The first step in selecting the right bar size is to honestly assess your cutting needs. What type of wood will you be cutting? What size trees will you be felling? What tasks will you be performing most often?
- Softwoods vs. Hardwoods: Softwoods like pine and fir are easier to cut than hardwoods like oak and maple. A longer bar might be suitable for softwoods, while a shorter bar might be preferable for hardwoods.
- Tree Diameter: The diameter of the trees you’ll be felling is a critical factor. Your bar length should be at least slightly longer than the diameter of the trees you’ll be cutting.
- Task Specificity: Are you primarily felling trees, bucking logs, or limbing branches? Felling often requires a longer bar for reaching through larger trunks, while limbing might be easier with a shorter, more maneuverable bar.
Consider this example: I once took down a massive oak tree with my 038 Magnum. The tree was easily over 36 inches in diameter at the base. I used a 28-inch bar, which was just long enough to get the job done, but it required careful planning and multiple cuts. If I had been regularly felling trees of that size, I would have invested in a longer bar.
Takeaway: Take the time to analyze your typical cutting scenarios. This will help you narrow down your bar size options.
Tip #2: Understanding Bar Length and Saw Performance
The length of your chainsaw bar directly affects its performance. A longer bar increases your reach and cutting capacity, but it also requires more power from the saw. A shorter bar is more maneuverable and requires less power, but it limits the size of the wood you can cut.
- Longer Bar Advantages:
- Increased reach for felling larger trees.
- Ability to cut through thicker logs in a single pass.
- Reduced bending and strain on your back when bucking logs.
- Longer Bar Disadvantages:
- Requires more power from the saw, potentially slowing down cutting speed.
- Increased weight and reduced maneuverability.
- Higher risk of kickback, especially for inexperienced users.
- Shorter Bar Advantages:
- Improved maneuverability, making it easier to limb branches and work in tight spaces.
- Reduced weight and fatigue.
- Lower risk of kickback.
- Shorter Bar Disadvantages:
- Limited cutting capacity.
- May require multiple cuts to fell larger trees.
- Can increase bending and strain on your back when bucking logs.
I recall one instance when I was helping a friend clear some land. He insisted on using a 32-inch bar on his Stihl MS290, which is a less powerful saw than the 038 Magnum. The saw struggled to pull the long chain, and the cutting speed was painfully slow. After switching to a 20-inch bar, the saw performed much better, and the work went much faster.
Takeaway: Choose a bar length that balances cutting capacity with the power of your Stihl 038 Magnum. Don’t overload your saw with a bar that’s too long.
Tip #3: Recommended Bar Sizes for the Stihl 038 Magnum
The Stihl 038 Magnum is a versatile saw that can handle a range of bar sizes. However, based on my experience and the saw’s specifications, I recommend the following bar lengths:
- 16-inch Bar: Ideal for limbing branches, cutting small trees, and light firewood processing. This is the most maneuverable option and offers the lowest risk of kickback.
- 18-inch Bar: A good all-around choice for general-purpose cutting. It provides a balance of cutting capacity and maneuverability, making it suitable for a variety of tasks.
- 20-inch Bar: A popular choice for felling medium-sized trees and bucking logs. It offers ample cutting capacity without being too unwieldy.
- 24-inch Bar: Suitable for felling larger trees and cutting thick logs. This bar length requires more power from the saw and is best suited for experienced users.
- 28-inch Bar: For very large diameter logs. Demands significant expertise.
These are general recommendations. The ideal bar size for you will depend on your specific cutting needs and experience level.
Personal Anecdote: I primarily use a 20-inch bar on my 038 Magnum for most of my firewood processing. It’s the perfect balance for the size of logs I typically encounter. However, I also keep a 16-inch bar on hand for limbing and smaller jobs.
Takeaway: Consider starting with an 18-inch or 20-inch bar if you’re unsure. You can always experiment with different lengths to find what works best for you.
Tip #4: Chain Type and Bar Compatibility
Choosing the right chain for your bar is just as important as selecting the correct bar length. The chain must be compatible with the bar’s gauge and pitch.
- Gauge: The gauge refers to the thickness of the drive links that fit into the bar groove. Common gauges include .050″, .058″, and .063″. Make sure the chain gauge matches the bar gauge.
- Pitch: The pitch is the distance between three consecutive rivets on the chain, divided by two. Common pitches include 3/8″ and .325″. Again, ensure the chain pitch matches the bar pitch.
- Chain Type: Different chain types are designed for different cutting applications.
- Full Chisel: Aggressive cutting, best for clean wood.
- Semi-Chisel: More durable, better for dirty or frozen wood.
- Low-Kickback: Designed to reduce the risk of kickback, ideal for beginners.
I once made the mistake of using the wrong chain on my bar. The chain was too loose, and it kept jumping off the bar. It was a frustrating and potentially dangerous experience. Always double-check the chain specifications before installing it on your bar.
Bar Compatibility: The Stihl 038 Magnum typically uses a 3/8″ pitch chain with a .050″ or .063″ gauge. Consult your owner’s manual or a Stihl dealer to confirm the correct specifications for your bar.
Takeaway: Always use a chain that is compatible with your bar’s gauge and pitch. Choose a chain type that is appropriate for the type of wood you’ll be cutting and your skill level.
Tip #5: Bar Maintenance and Safety
Proper bar maintenance is essential for ensuring optimal performance and extending the life of your bar. Regular maintenance includes:
- Cleaning: Clean the bar groove regularly to remove sawdust and debris. Use a bar groove cleaner or a small screwdriver.
- Lubrication: Ensure the bar is properly lubricated. Use a high-quality bar and chain oil. Check the oil level frequently and refill as needed.
- Filing: Sharpen the chain regularly to maintain its cutting efficiency. Use a chainsaw file and follow the manufacturer’s instructions.

I’ve seen firsthand the devastating consequences of chainsaw accidents. Always be aware of your surroundings, maintain a firm grip on the saw, and never operate a chainsaw when you are tired or under the influence of drugs or alcohol.
Case Study: A local logger I know neglected to maintain his chainsaw bar properly. The bar became worn and damaged, which led to increased friction and heat. One day, the bar overheated and snapped, causing the chain to fly off and strike him in the leg. Fortunately, he was wearing chainsaw chaps, which prevented a more serious injury.
Takeaway: Prioritize safety and maintain your bar properly. Regular maintenance will not only improve performance but also extend the life of your bar and reduce the risk of accidents.
Beyond the Basics: Advanced Considerations
Once you’ve mastered the fundamentals of bar selection and maintenance, you can start exploring more advanced considerations:
- Hardwood Cutting Techniques: When cutting hardwoods, use a sharp chain and avoid forcing the saw. Let the chain do the work. Use a narrower kerf chain to reduce the amount of wood the saw needs to remove.
- Felling Techniques: When felling trees, use proper felling techniques to control the direction of the fall. This will help prevent damage to property and reduce the risk of injury.
- Limbing Techniques: When limbing branches, work from the bottom up to avoid being struck by falling limbs. Use a firm grip and keep the saw close to your body.
- Bucking Techniques: When bucking logs, use a sawbuck or other support to keep the log off the ground. This will make it easier to cut and reduce the risk of pinching the bar.
- Chain Sharpening Techniques: Learn how to properly sharpen your chain using a chainsaw file or a chain grinder. A sharp chain will cut more efficiently and reduce the risk of kickback.
I’ve spent years honing my chainsaw skills, and I’m still learning new things. The key is to be patient, practice regularly, and always prioritize safety.
The Importance of Chain Tension
Proper chain tension is crucial for safe and efficient chainsaw operation. A chain that is too loose can derail from the bar, while a chain that is too tight can cause excessive wear and tear on the bar and chain.
Checking Chain Tension: To check chain tension, pull the chain away from the bar in the middle of the underside. There should be a small amount of slack, typically around 1/8 inch.
Adjusting Chain Tension: Most chainsaws have a chain tensioning screw located on the side of the saw. Use a screwdriver or wrench to adjust the tension. Loosen the bar nuts slightly before adjusting the tension, and then tighten them securely after making the adjustment.
Cold vs. Hot Tension: Adjust chain tension when the chain is cold. The chain will expand as it heats up during operation, so it’s better to have it slightly looser when cold than too tight when hot.
Takeaway: Regularly check and adjust chain tension to ensure safe and efficient chainsaw operation.
Troubleshooting Common Problems
Even with proper bar selection and maintenance, you may encounter problems with your chainsaw from time to time. Here are some common problems and their solutions:
- Chain Saw Won’t Start: Check the fuel level, spark plug, and air filter. Make sure the choke is in the correct position.
- Chain Saw Starts but Stalls: Check the fuel filter and carburetor. Adjust the carburetor settings if necessary.
- Chain Saw Cuts Slowly: Sharpen the chain. Check the bar for wear and damage.
- Chain Saw Smokes Excessively: Check the fuel mixture. Use a high-quality two-stroke oil.
- Chain Saw Vibrates Excessively: Check the bar and chain for damage. Tighten all bolts and screws.
- Chain Comes Off the Bar: Check the chain tension. Make sure the chain is the correct size for the bar. Check the bar for wear and damage.
I’ve learned to troubleshoot many common chainsaw problems myself. However, if you’re not comfortable working on your chainsaw, it’s best to take it to a qualified repair shop.
