I’ll share my pro tips, learned through years of practical experience, to help you make informed decisions and work smarter, not harder.

Stihl Chainsaw Bars: A Logger’s Deep Dive

The chainsaw bar is arguably the unsung hero of the entire chainsaw system. It’s the backbone that supports the chain, guides the cut, and ultimately determines the efficiency and safety of your work. Understanding its nuances is crucial, whether you’re a seasoned logger or a weekend warrior tackling firewood prep.

Why the Right Bar Matters: More Than Just Length

A chainsaw bar is much more than just a piece of metal. It directly affects:

Cutting Speed: A bar that’s too long for your saw’s power will bog it down, reducing cutting speed and increasing wear and tear.
Safety: An improperly sized or worn bar can lead to kickback, a dangerous situation where the saw suddenly jumps back towards the operator.
Precision: The bar’s design influences the straightness and smoothness of your cuts.
Saw Longevity: Matching the bar to the saw and the task extends the life of both.

I’ve seen firsthand the consequences of using the wrong bar. Early in my career, I tried to run a 36-inch bar on a saw that was really designed for a 24-inch. The saw struggled, the chain constantly needed sharpening, and I was exhausted by the end of the day. The experience taught me the importance of matching the bar to the saw’s capabilities.

Key Terms and Concepts: A Chainsaw Bar Glossary

Before diving into the specifics, let’s define some essential terms:

Bar Length: This is the usable cutting length of the bar, measured from the tip to where the bar enters the saw body. It’s often listed in inches.
Gauge: The width of the drive links on the chain that fit into the bar’s groove. Common gauges include .050″, .058″, and .063″. Using the wrong gauge will prevent the chain from fitting properly.
Pitch: The distance between three consecutive rivets on the chain, divided by two. Common pitches include 3/8″ and .325″. The pitch of the chain must match the sprocket and bar.
Drive Links: The small teeth on the chain that fit into the bar’s groove and are pulled by the sprocket.
Sprocket Nose: A replaceable, toothed wheel at the tip of some bars that reduces friction and wear.
Laminated Bar: A bar constructed from multiple layers of steel, welded together. These are typically lighter and less expensive than solid bars.
Solid Bar: A bar made from a single piece of hardened steel. These are more durable and resistant to bending, making them suitable for heavy-duty use.
Rollomatic Bar: Stihl’s name for their laminated bars with a replaceable sprocket nose.
Duromatic Bar: Stihl’s name for their solid bars.

Stihl Chainsaw Bar Types: Understanding the Options

Stihl offers a variety of chainsaw bars designed for different applications. Understanding the differences between them is crucial for making the right choice.

Rollomatic E (Laminated): These are lightweight and versatile bars, ideal for general purpose cutting and firewood preparation. They are a good choice for homeowners and occasional users. Available in various lengths, they are typically less expensive than solid bars.
Rollomatic ES Light (Laminated): These bars are designed to be even lighter than the standard Rollomatic E, reducing fatigue during extended use. They often feature a narrower profile. I often recommend these to users who are doing a lot of limbing, or anyone who wants to reduce the weight of their saw.
Rollomatic ES (Laminated): A more robust laminated bar, offering increased durability compared to the Rollomatic E. These are suitable for more demanding tasks and professional use.
Duromatic E (Solid): These are heavy-duty, solid steel bars designed for the toughest jobs. They are extremely resistant to wear and bending, making them ideal for felling large trees, cutting hardwoods, and working in abrasive conditions.
Carving Bars: These specialized bars have a narrow, pointed tip for detailed carving work. They are typically used with smaller, lightweight chainsaws.
Specialty Bars: Stihl also offers specialized bars for specific applications, such as concrete cutting or rescue work.

Pro Tip #1: Matching the Bar to Your Chainsaw Model

The most crucial step in selecting a chainsaw bar is ensuring compatibility with your Stihl chainsaw model. Each saw is designed to handle a specific range of bar lengths and chain types.

Finding the Right Fit: Stihl’s Recommendation

Stihl provides detailed information in their owner’s manuals and on their website about the recommended bar lengths and chain types for each chainsaw model. Always consult this information before purchasing a new bar.

Here’s a general guideline, but remember to always check your owner’s manual:

Small Chainsaws (e.g., MS 170, MS 180): Typically use bars ranging from 12″ to 16″.
Mid-Size Chainsaws (e.g., MS 250, MS 271): Usually accommodate bars from 16″ to 20″.
Large Chainsaws (e.g., MS 362, MS 462): Can handle bars from 20″ to 28″ or even longer.
Professional Chainsaws (e.g., MS 661, MS 881): Designed for bars ranging from 25″ to 48″ or more.

Why Over-Barring is a Bad Idea

Trying to use a bar that’s too long for your saw can lead to several problems:

Reduced Power: The saw will struggle to pull the chain through the wood, resulting in slower cutting and increased fuel consumption.
Increased Wear and Tear: The engine and clutch will be under excessive stress, shortening the lifespan of the saw.
Safety Hazards: The saw may be more prone to kickback, and the operator will have less control.

I once saw a guy trying to use a 30-inch bar on an MS 250. It was painful to watch. The saw was laboring so hard that it was smoking, and he was barely making any progress. He ended up damaging the clutch and having to take the saw in for repairs.

Understanding Chain Compatibility

The chain must match the bar in terms of gauge and pitch. Using the wrong chain can damage the bar, the saw, and potentially cause serious injury.

Gauge: Ensure the chain gauge matches the bar groove width. If the chain is too narrow, it will rattle and not cut properly. If it’s too wide, it won’t fit.
Pitch: The chain pitch must match the sprocket and the bar’s sprocket nose (if equipped). If the pitch is mismatched, the chain won’t engage properly with the sprocket, leading to damage and potential injury.

Case Study: Choosing the Right Bar for an MS 271

Let’s say you have a Stihl MS 271 chainsaw. According to Stihl’s documentation, the recommended bar length is 16″ to 20″. For general purpose cutting and firewood preparation, a 18″ Rollomatic E bar with a .325″ pitch and .063″ gauge chain would be a good choice. If you were primarily felling larger trees, you might opt for a 20″ bar. If you are cutting small trees and doing limbing work, a 16″ bar will be more maneuverable.

Pro Tip #2: Considering the Wood Type and Cutting Conditions

The type of wood you’re cutting and the conditions you’re working in should also influence your bar selection.

Hardwood vs. Softwood

Hardwoods (e.g., oak, maple, hickory): These dense woods require more power to cut. A longer bar may be necessary for felling large hardwood trees, but be sure your saw has the power to handle it. A solid bar (Duromatic E) is generally recommended for increased durability.
Softwoods (e.g., pine, fir, spruce): These woods are easier to cut and typically require less power. A shorter, lighter bar (Rollomatic E or ES Light) may be sufficient for most tasks.

Dirty or Abrasive Conditions

Working in dirty or abrasive conditions, such as cutting near the ground or through wood with embedded dirt, will accelerate wear on the bar and chain. In these situations, a solid bar (Duromatic E) is highly recommended. The hardened steel construction will resist wear and abrasion better than a laminated bar.

I’ve worked in areas where the soil is very sandy, and it gets kicked up onto the wood when you fell the tree. I quickly learned that using a solid bar in those conditions was essential to prevent premature wear. I also make sure to clean the bar and chain frequently to remove any accumulated dirt and debris.

Frozen Wood

Cutting frozen wood can be particularly challenging. The wood is harder and more brittle, increasing the risk of kickback. It’s crucial to use a sharp chain and maintain a steady cutting speed. A solid bar is often preferred for its durability and resistance to bending.

Bar Maintenance: Extending its Life

Proper bar maintenance is essential for maximizing its lifespan and ensuring safe operation.

Cleaning: Regularly clean the bar groove with a bar groove cleaner or a small screwdriver to remove sawdust and debris. This will ensure proper chain lubrication.
Filing: Use a bar dressing tool to remove burrs and level the bar rails. This will prevent the chain from binding and improve cutting performance.
Lubrication: Ensure the bar and chain are properly lubricated. Use a high-quality bar and chain oil and check the oil level frequently.
Sprocket Nose Maintenance: If your bar has a replaceable sprocket nose, inspect it regularly for wear and replace it when necessary.
Storage: Store the bar in a dry place to prevent rust and corrosion.

Pro Tip #3: Understanding Bar Construction and Features

The construction and features of a chainsaw bar can significantly impact its performance and durability.

- Disadvantages: More friction and wear, shorter bar life.
- Applications: Suitable for occasional use and lighter tasks.

Bar Length and Cutting Diameter

The bar length should be chosen based on the diameter of the wood you’ll be cutting. As a general rule, the bar length should be at least two inches longer than the diameter of the largest tree you plan to fell. This allows you to safely and effectively cut through the tree without having to “bury” the bar completely.

However, remember that a longer bar requires more power. If you frequently cut smaller trees, a shorter bar will be more maneuverable and efficient.

Understanding Kickback Reduction Features

Some chainsaw bars incorporate features designed to reduce the risk of kickback. These features may include:

Narrow-Kerf Chains: These chains have a narrower cutting width, reducing the amount of wood that the chain engages with at any given time.
Low-Kickback Chains: These chains have special guard links that help to prevent the chain from grabbing and kicking back.
Reduced-Tip Bars: These bars have a smaller tip radius, which reduces the likelihood of the tip catching on the wood and causing kickback.

While these features can help to reduce the risk of kickback, it’s important to remember that they are not a substitute for proper training and safe operating practices.

Case Study: Choosing Between a Rollomatic E and a Duromatic E

Let’s say you’re a homeowner who primarily uses your chainsaw for cutting firewood and trimming trees around your property. You have a Stihl MS 250 chainsaw. In this case, a Rollomatic E bar in the 16″ to 18″ range would likely be the best choice. It’s lightweight, versatile, and affordable.

However, if you’re a professional logger who fells large trees and works in abrasive conditions, a Duromatic E bar would be a better investment. Its durability and resistance to wear will more than offset the higher cost.

Beyond the Basics: Advanced Considerations

Once you’ve mastered the fundamentals of chainsaw bar selection, you can start to explore some more advanced considerations.

Chain Sharpening and Maintenance

A sharp chain is essential for safe and efficient cutting. Learn how to properly sharpen your chain using a file or a chain grinder. Regular sharpening will not only improve cutting performance but also extend the life of your bar and chain.

I always carry a file with me when I’m working in the woods. I sharpen the chain every few hours, or more frequently if I’m cutting dirty wood. A sharp chain makes a huge difference in cutting speed and reduces the amount of effort required.

Understanding Chain Types

There are many different types of chainsaw chains available, each designed for specific applications. Some common chain types include:

Full-Chisel Chains: These chains have square-cornered cutters that are very aggressive and cut quickly. However, they are also more prone to kickback and require more skill to use.
Semi-Chisel Chains: These chains have rounded-corner cutters that are less aggressive than full-chisel chains but are also more forgiving and easier to sharpen.
Low-Kickback Chains: These chains have special guard links that help to prevent kickback. They are a good choice for beginners and occasional users.

Choose the chain type that best suits your needs and skill level.

Bar Oil Selection

Using the right bar oil is crucial for lubricating the chain and preventing wear on the bar. Choose a high-quality bar oil that is specifically designed for chainsaw use. Avoid using motor oil or other substitutes, as they may not provide adequate lubrication and could damage your saw.

I prefer to use a synthetic bar oil, as it provides better lubrication and is less likely to gum up in cold weather. I also make sure to check the oil level frequently and top it off as needed.

Safety Gear: Protecting Yourself

Operating a chainsaw is inherently dangerous. Always wear appropriate safety gear, including:

Chainsaw Chaps: These protect your legs from accidental cuts.
Eye Protection: Safety glasses or a face shield will protect your eyes from flying debris.
Hearing Protection: Earplugs or earmuffs will protect your hearing from the loud noise of the chainsaw.
Gloves: Gloves will provide a better grip and protect your hands from cuts and abrasions.
Helmet: A helmet will protect your head from falling branches and other hazards.

Never operate a chainsaw without wearing the proper safety gear.

Felling Techniques: Cutting Down Trees Safely

Felling trees is a dangerous task that should only be performed by experienced individuals. If you’re not comfortable felling trees yourself, hire a professional arborist.

If you do decide to fell trees yourself, be sure to follow these safety guidelines:

Assess the Tree: Before you start cutting, assess the tree for any signs of weakness or instability. Look for dead branches, cracks in the trunk, and leaning.
Plan Your Escape Route: Before you start cutting, plan your escape route. Make sure you have a clear path away from the tree in case it falls unexpectedly.
Use Proper Felling Techniques: Use proper felling techniques, such as making a notch cut and a back cut. These techniques will help to control the direction of the fall.
Be Aware of Your Surroundings: Be aware of your surroundings. Make sure there are no people, buildings, or power lines in the path of the falling tree.
