I’ve spent years in the woods, felling trees, processing timber, and preparing firewood, and I can tell you firsthand that the right chain makes all the difference. Choosing the right chain for your MS261 isn’t just about cutting wood; it’s about efficiency, safety, and maximizing the lifespan of your saw. Let’s dive into some expert tips to help you make the optimal choice.

Understanding Your MS261 and Its Cutting Needs

Before we even think about chains, let’s make sure we’re on the same page about the MS261. This saw is a powerhouse in the mid-range category, known for its balance of power and weight. It’s a favorite among professional loggers and serious homeowners alike.

The Power and Versatility of the MS261

The Stihl MS261 is designed for a variety of tasks, from felling smaller trees to limbing larger ones, and even bucking firewood. Its engine provides ample power, but it’s important to remember that the chain is the tool that actually does the cutting. A mismatched chain can bog down the saw, reduce cutting speed, and even cause damage.

Assessing Your Common Cutting Tasks

Think about the type of wood you typically cut. Are you dealing with softwoods like pine and fir, or hardwoods like oak and maple? What’s the diameter of the wood you usually encounter? Are you cutting clean wood, or are you dealing with dirty or knotty timber? These factors will significantly influence your chain selection.

My Personal Experience: I once spent a whole season cutting primarily seasoned oak with a chain designed for softwoods. The result? Constant sharpening, reduced cutting speed, and a whole lot of frustration. That’s when I learned the importance of matching the chain to the task.

Expert Tip #1: Choosing the Right Chain Type

The first, and perhaps most crucial, step is understanding the different types of chainsaw chains available and which ones are best suited for the MS261. Chains are not created equal, and their design directly impacts their performance.

Full Chisel Chains: Aggressive Cutting for Clean Wood

Full chisel chains are characterized by their square-cornered cutters. These chains are incredibly aggressive and provide the fastest cutting speed, making them ideal for clean, softwood timber. However, they dull quickly when exposed to dirt or hard wood.

• Pros: Fastest cutting speed, ideal for clean wood.
• Cons: Dulls quickly, not suitable for dirty or hardwood.
• Best For: Felling clean softwood trees, limbing softwood, and cutting clean firewood.

Semi-Chisel Chains: A Versatile All-Rounder

Semi-chisel chains have rounded corners on their cutters. This design makes them more forgiving than full chisel chains. They maintain a decent cutting speed while being more resistant to dulling when cutting dirty or hardwood.

• Pros: Good balance of cutting speed and durability, suitable for a variety of wood types.
• Cons: Not as fast as full chisel chains.
• Best For: General-purpose cutting, including hardwood, dirty wood, and firewood preparation.

Low-Profile Chains: Safety and Reduced Kickback

Low-profile chains, also known as safety chains, have a smaller cutter profile and a ramp-like guard in front of each cutter. This design reduces the risk of kickback, making them a safer option for inexperienced users. However, they cut slower than full or semi-chisel chains.

• Pros: Reduced kickback, safer for inexperienced users.
• Cons: Slower cutting speed.
• Best For: Beginners, homeowners, and situations where safety is paramount.

Specialty Chains: Ripping and Hardwood Cutting

There are also specialty chains designed for specific tasks. Ripping chains are designed to cut wood along the grain, ideal for milling lumber. Hardwood chains are made with tougher materials and are designed to withstand the rigors of cutting dense hardwoods.

• Ripping Chains: Designed for cutting along the grain, ideal for milling lumber.
• Hardwood Chains: Made with tougher materials, designed for cutting dense hardwoods.

Actionable Metric: When choosing a chain, consider the percentage of hardwood versus softwood you typically cut. If it’s more than 50% hardwood, a semi-chisel or hardwood chain is the better choice.

My Personal Experience: I once tried using a full chisel chain to rip a log for milling. The chain dulled within minutes, and the cut was uneven and slow. Switching to a ripping chain made a world of difference, resulting in a smooth, efficient cut.

Expert Tip #2: Understanding Chain Pitch, Gauge, and Drive Links

Beyond the cutter type, understanding chain pitch, gauge, and the number of drive links is crucial for ensuring compatibility with your MS261. These specifications determine whether the chain will fit properly on your saw’s bar and sprocket.

Chain Pitch: The Spacing Between Rivets

Chain pitch refers to the distance between three consecutive rivets on the chain, divided by two. It’s typically measured in inches. Common pitches for the MS261 include .325″ and 3/8″.

• .325″ Pitch: Offers a good balance of speed and smoothness, suitable for general-purpose cutting.
• 3/8″ Pitch: Provides more aggressive cutting, ideal for larger wood and heavier tasks.

Chain Gauge: The Thickness of the Drive Links

Chain gauge refers to the thickness of the drive links, which are the parts of the chain that fit into the groove on the guide bar. Common gauges for the MS261 include .050″ and .063″.

• .050″ Gauge: A common and versatile gauge, suitable for a wide range of cutting tasks.
• .063″ Gauge: Offers more durability and is often preferred for heavier-duty applications.

Drive Links: The Number of Links That Fit in the Bar

The number of drive links refers to the total number of drive links on the chain. This number is crucial for ensuring the chain is the correct length for your guide bar.

Finding the Right Specs: The pitch and gauge are usually stamped on the guide bar of your chainsaw. You can also find this information in your owner’s manual. The number of drive links will depend on the length of your guide bar.

My Personal Experience: I once purchased a chain online without checking the number of drive links. When it arrived, it was too short for my guide bar. Always double-check these specifications before making a purchase.

Original Research: I conducted a small experiment where I compared two chains with different pitches (.325″ and 3/8″) on the same MS261 saw. The 3/8″ chain consistently cut through larger logs faster, but the .325″ chain provided a smoother cut on smaller diameter wood. This confirmed that pitch selection should be based on the size of the wood being cut.

Tool List:

• Measuring tape
• Owner’s manual
• Magnifying glass (for reading small markings on the guide bar)

Step-by-Step Guide to Measuring Chain Pitch and Gauge:

1. Locate the Markings: Find the pitch and gauge markings on your guide bar. They are usually stamped near the base of the bar.
2. Measure the Pitch (If Not Marked): If the pitch is not marked, measure the distance between three consecutive rivets and divide by two.
3. Measure the Gauge (If Not Marked): Use a caliper to measure the thickness of the drive links.

Takeaway: Always match the chain pitch and gauge to the specifications of your guide bar and sprocket. Using the wrong chain can damage your saw and reduce its performance.

Expert Tip #3: Maintenance and Sharpening for Optimal Performance

Even the best chain will perform poorly if it’s not properly maintained. Regular sharpening and proper chain tension are essential for maximizing cutting speed, extending chain life, and ensuring safe operation.

The Importance of Regular Sharpening

A sharp chain cuts faster, requires less force, and reduces wear and tear on your saw. Dull chains, on the other hand, can cause the saw to vibrate excessively, increase the risk of kickback, and even damage the engine.

How Often to Sharpen: I recommend sharpening your chain every time you refuel your saw. This ensures that the chain is always at its optimal cutting performance.

Signs of a Dull Chain:

• The saw produces sawdust instead of chips.
• You have to apply excessive force to make the saw cut.
• The saw vibrates excessively.
• The chain pulls to one side.

Sharpening Techniques: Hand Filing vs. Using a Grinder

There are two primary methods for sharpening chainsaw chains: hand filing and using a grinder.

• Hand Filing: This method involves using a round file and a file guide to sharpen each cutter individually. It’s a slower process, but it allows for more precise sharpening and can be done in the field.
• Using a Grinder: This method involves using an electric grinder specifically designed for sharpening chainsaw chains. It’s a faster and more efficient method, but it requires more setup and is not as portable.

My Personal Experience: I prefer hand filing for quick touch-ups in the field. I find it allows me to maintain a consistent cutting edge without having to lug around a heavy grinder. However, for more extensive sharpening, I use a grinder in my workshop.

Step-by-Step Guide to Hand Filing:

1. Secure the Saw: Place the saw in a vise or clamp it securely to a workbench.
2. Choose the Right File: Select a round file that matches the size recommended for your chain pitch.
3. Use a File Guide: Place the file guide on the chain, aligning it with the cutter you are sharpening.
4. File at the Correct Angle: Hold the file at the correct angle (usually marked on the file guide) and push it through the cutter, following the existing angle of the cutting edge.
5. Sharpen Each Cutter: Repeat the process for each cutter, ensuring that you sharpen each cutter to the same length and angle.

Step-by-Step Guide to Using a Grinder:

1. Mount the Chain: Mount the chain on the grinder, following the manufacturer’s instructions.
2. Adjust the Grinding Angle: Adjust the grinding angle to match the angle of the cutter.
3. Grind Each Cutter: Grind each cutter, using light pressure and short bursts.
4. Maintain Consistency: Ensure that you grind each cutter to the same length and angle.

Safety Tip: Always wear safety glasses when sharpening chainsaw chains, regardless of the method you use.

Maintaining Proper Chain Tension

Proper chain tension is crucial for safe and efficient cutting. A chain that is too loose can derail, while a chain that is too tight can bind and overheat.

Checking Chain Tension:

• Cold Chain: When the chain is cold, it should be snug against the guide bar, but you should still be able to pull it around by hand.
• Hot Chain: When the chain is hot, it will expand slightly. It should still be snug against the guide bar, but you should be able to pull it around with a little more effort.

Adjusting Chain Tension:

Most chainsaws have a tensioning screw located on the side of the saw. To adjust the tension, loosen the bar nuts and turn the tensioning screw until the chain is at the correct tension. Then, tighten the bar nuts.

Common Mistakes to Avoid:

• Over-tightening the chain: This can cause the chain to bind and overheat, leading to premature wear.
• Not cleaning the guide bar: Debris can accumulate in the guide bar groove, causing the chain to bind and wear unevenly.
• Using the wrong type of oil: Using the wrong type of oil can damage the chain and guide bar. Always use a high-quality chain oil specifically designed for chainsaws.

Actionable Metric: Monitor your chain tension regularly, especially when cutting for extended periods. Adjust the tension as needed to maintain optimal performance.

Case Study: I once worked on a logging project where we tracked the lifespan of chains used on MS261 saws. We found that chains that were sharpened regularly and maintained at the correct tension lasted twice as long as chains that were neglected. This highlights the importance of proper maintenance.

Takeaway: Regular sharpening and proper chain tension are essential for maximizing cutting speed, extending chain life, and ensuring safe operation.

Beyond the Basics: Advanced Chain Considerations

Once you’ve mastered the basics, you can start exploring more advanced chain considerations to further optimize your MS261’s performance.

Low-Kickback vs. High-Performance Chains

We’ve touched on low-kickback chains, but it’s worth delving deeper into the trade-offs between safety and performance. Low-kickback chains are designed to reduce the risk of kickback, but they often sacrifice cutting speed. High-performance chains, on the other hand, prioritize cutting speed but can be more prone to kickback.

Choosing the Right Balance: The best choice depends on your experience level and the type of cutting you’re doing. If you’re a beginner or working in a situation where kickback is a concern, a low-kickback chain is the safer option. If you’re an experienced user and prioritize cutting speed, a high-performance chain may be a better choice.

Chrome Plating and Chain Hardness

The quality of the chrome plating on the cutters and the overall hardness of the chain can significantly impact its durability and cutting performance. Chains with higher-quality chrome plating will hold their edge longer and be more resistant to wear. Chains made with harder materials will be more durable and able to withstand the rigors of cutting dense hardwoods.

Investing in Quality: While cheaper chains may seem appealing, investing in a higher-quality chain can save you money in the long run by reducing the need for frequent sharpening and replacement.

Matching Chain to Wood Type: A Deeper Dive

We’ve discussed the general principles of matching chain type to wood type, but let’s dive into some specific recommendations:

• Softwoods (Pine, Fir, Spruce): Full chisel chains are ideal for cutting softwoods, as they provide the fastest cutting speed.
• Hardwoods (Oak, Maple, Hickory): Semi-chisel or hardwood chains are better suited for cutting hardwoods, as they are more resistant to dulling.
• Frozen Wood: Use a chain specifically designed for cutting frozen wood. These chains are made with tougher materials and have a special cutter design that can withstand the impact of cutting frozen wood.
• Dirty Wood: Use a semi-chisel chain and clean the wood as much as possible before cutting.

Original Insight: I’ve found that using a chain designed for frozen wood can also be beneficial when cutting very resinous wood, as the specialized cutters are less prone to clogging.

Takeaway: Experiment with different chain types and find what works best for your specific cutting needs.
