Unleashing the Beast: Finding the Perfect Chain for Your Stihl MS310

The Stihl MS310 is a solid mid-range chainsaw, known for its reliability and power. But even the best saw is only as good as the chain you put on it. The right chain can transform your MS310 from a decent tool into a cutting machine. The wrong chain? Well, you’ll be fighting it every step of the way, wasting time, energy, and potentially damaging your saw.

Think of it like this: you wouldn’t put cheap tires on a high-performance sports car, would you? The same principle applies to chainsaws. The chain is the interface between the saw and the wood, and it’s responsible for doing the actual cutting.

Why Chain Choice Matters: More Than Just Sharp Teeth

Choosing the right chain isn’t just about finding something that’s sharp. It’s about matching the chain’s characteristics to the specific task at hand. Here’s why it’s so important:

• Cutting Efficiency: A well-matched chain will cut faster and smoother, reducing the amount of effort required from both you and the saw. This translates to less fatigue and increased productivity.
• Saw Performance: Using the wrong chain can strain your saw’s engine, leading to overheating, reduced power, and premature wear and tear.
• Safety: A dull or inappropriate chain can kick back more easily, increasing the risk of injury.
• Wood Type: Different chains are designed for different types of wood. Softwoods like pine require a different chain than hardwoods like oak or maple.
• Cutting Conditions: Are you cutting clean wood, or are you dealing with dirty, sandy logs? Some chains are more resistant to wear and tear in abrasive conditions.
• User Experience: A chain that’s well-suited to your skill level will be easier to control and less prone to errors.

Data Point: Studies have shown that using the correct chain type for the wood being cut can increase cutting efficiency by as much as 25%. This means you can cut more wood in less time, with less strain on your saw and your body.

Understanding Chain Terminology: A Quick Primer

Before we get into my top picks, let’s quickly review some basic chain terminology. This will help you understand the differences between the various options and make a more informed decision.

• Pitch: The distance between any three consecutive rivets on the chain, divided by two. Common pitches for the MS310 are .325″ and 3/8″.
• Gauge: The thickness of the drive links, which fit into the bar groove. The MS310 typically uses a .063″ gauge.
• Drive Links: The number of drive links determines the length of the chain and is specific to the bar length. A 20-inch bar on an MS310 usually requires around 72 drive links.
• Cutter Type: This refers to the shape of the cutting teeth. Common types include:
  • Full Chisel: Aggressive cutting, best for clean wood and experienced users.
  • Semi-Chisel: More forgiving than full chisel, good for general-purpose cutting and slightly dirty wood.
  • Low-Profile (Micro-Chisel): Designed for safety and ease of use, ideal for beginners and smaller saws.
• Bumper Links (Tie Straps): These links are located between the cutting teeth and help reduce kickback. Chains with more bumper links are generally safer but may cut slightly slower.

Important Note: Always consult your Stihl MS310 owner’s manual to confirm the correct pitch, gauge, and drive link count for your specific bar length. Using the wrong chain can damage your saw and create a safety hazard.

Choosing the Right Chain for Your Needs: A Personalized Approach

Now that I’ve shared my top picks, it’s time to figure out which chain is the best choice for you. Here are some factors to consider:

• Your Experience Level: Are you a seasoned pro or a beginner? If you’re new to chainsaws, I recommend starting with a low-profile or semi-chisel chain. As you gain experience, you can move up to a full chisel chain for faster cutting.
• The Type of Wood You’ll Be Cutting: Softwoods like pine are generally easier to cut than hardwoods like oak or maple. If you’re primarily cutting softwoods, you can get away with a less aggressive chain. If you’re cutting hardwoods, you’ll want a chain with more bite.
• The Cutting Conditions: Are you cutting clean wood, or are you dealing with dirty, sandy logs? If you’re cutting dirty wood, choose a chain that’s more resistant to dulling, such as a semi-chisel chain.
• Your Budget: Chainsaw chains can range in price from relatively inexpensive to quite expensive. Consider your budget when making your decision, but don’t sacrifice quality for price. A good quality chain will last longer and perform better, ultimately saving you money in the long run.
• The Size of the Wood: Are you cutting small branches or large logs? Low-profile chains are better suited for small branches, while full chisel chains are more efficient for large logs.

Data-Backed Advice: According to the U.S. Forest Service, the average homeowner cuts approximately 1-3 cords of firewood per year. For this volume, a durable semi-chisel chain like the Oregon 72LPX would likely provide the best balance of performance, durability, and cost.

Maintaining Your Chain: Keeping It Sharp and Ready to Roll

No matter which chain you choose, it’s essential to keep it properly maintained. A sharp chain is a safe chain, and it will also cut more efficiently and last longer. Here are some tips for maintaining your chainsaw chain:

• Sharpen Regularly: Sharpen your chain whenever it starts to feel dull or when you notice that it’s taking more effort to cut through wood. Learn to sharpen your chain with a file, or take it to a professional for sharpening.
• Check Chain Tension: Check the chain tension before each use and adjust as needed. A properly tensioned chain should be snug on the bar but still able to be pulled around by hand.
• Lubricate Frequently: Keep your chain well-lubricated with chainsaw bar and chain oil. This will reduce friction and wear and tear on the chain and bar.
• Clean Regularly: Clean your chain regularly with a wire brush to remove dirt and debris. This will help prevent premature dulling and wear.
