Understanding Chainsaw Chain Basics

Before we dive into the specifics of the Stihl MS210, let’s establish a solid foundation by understanding some key chainsaw chain concepts.

What is a Chainsaw Chain?

A chainsaw chain is a loop of interconnected cutting teeth, drive links, and tie straps that rotates around the chainsaw’s guide bar. The cutting teeth are responsible for removing wood, while the drive links engage with the sprocket on the chainsaw, propelling the chain around the bar. The tie straps connect the cutting teeth and drive links, providing structural integrity to the chain.

Key Chainsaw Chain Terminology

• Pitch: The distance between any three consecutive rivets on the chain, divided by two. It’s usually expressed in inches (e.g., 3/8″, .325″). The pitch determines the size of the sprocket that the chain will run on.
• Gauge: The thickness of the drive links, which must match the groove width of the guide bar. It’s also expressed in inches (e.g., .050″, .058″). Using the wrong gauge can cause the chain to bind or derail.
• Drive Link Count: The total number of drive links in the chain. This determines the overall length of the chain and must match the length of the guide bar.
• Cutting Tooth Type: Different chain designs feature different cutting tooth profiles, each optimized for specific cutting tasks. Common types include:
  • Full Chisel: Aggressive cutting teeth with square corners, ideal for fast cutting in clean wood.
  • Semi-Chisel: More rounded cutting teeth, offering a good balance of cutting speed and durability, suitable for a wider range of wood types.
  • Low-Profile (Micro-Chisel): Smaller, less aggressive cutting teeth, designed for safety and reduced kickback, often used on smaller chainsaws.
• Safety Features: Some chains incorporate features designed to reduce the risk of kickback, such as bumper drive links or depth gauges.

Green Wood vs. Seasoned Wood: A Critical Distinction

One of the most important distinctions to understand in wood processing is the difference between green wood and seasoned wood.

• Green Wood: This is freshly cut wood that still contains a high moisture content, typically ranging from 30% to over 100% (based on dry weight). Green wood is generally easier to cut because the moisture acts as a lubricant. However, it’s heavier, more prone to warping and shrinking as it dries, and less efficient to burn as firewood.
• Seasoned Wood: This is wood that has been allowed to dry, typically for 6-12 months, until its moisture content is reduced to around 20% or less. Seasoned wood is lighter, more stable, and burns more efficiently. However, it can be harder to cut than green wood, especially if it’s very dense.

The type of wood you’re cutting will influence the type of chain you choose and how you sharpen it. For example, if you’re primarily cutting green wood, a chain with a more aggressive cutting tooth profile (like a full chisel) might be a good choice. If you’re cutting seasoned hardwood, a more durable chain (like a semi-chisel) might be better.

Stihl MS210 Chain Size Guide: Understanding the Specifications

Now, let’s focus on the Stihl MS210 and its specific chain requirements.

Recommended Chain Specifications for the Stihl MS210

The Stihl MS210 is typically equipped with a 16-inch guide bar. Here are the standard chain specifications for this configuration:

• Pitch: 3/8″ (0.375″)
• Gauge: .050″
• Drive Link Count: 55

Important Note: Always double-check the specifications listed in your chainsaw’s owner’s manual. While the above specifications are common, there may be slight variations depending on the specific model and bar length.

How to Determine Your Current Chain Size

If you’re unsure about the size of your current chain, here’s how to determine it:

1. Check the Guide Bar: Many guide bars have the chain specifications stamped on them. Look for markings that indicate the pitch and gauge.
2. Count the Drive Links: Remove the chain from the chainsaw and count the number of drive links. This is the most accurate way to determine the chain’s length.
3. Measure the Pitch: Use a ruler or calipers to measure the distance between any three consecutive rivets on the chain, then divide by two.
4. Measure the Gauge: Use calipers to measure the thickness of the drive links.

Understanding Stihl Chain Codes

Stihl uses a specific coding system to identify their chainsaw chains. Understanding these codes can help you choose the right chain for your needs. Here’s a breakdown of some common Stihl chain codes:

• Rapid Micro (RM): A low-vibration, low-kickback chain with a semi-chisel cutting tooth. It’s a good all-around choice for homeowners and occasional users.
• Rapid Micro Comfort (RMC): Similar to RM, but with an additional bumper drive link for increased safety.
• Rapid Super (RS): A high-performance chain with a full-chisel cutting tooth. It’s designed for fast cutting in clean wood.
• Rapid Duro (RD): A carbide-tipped chain that’s extremely durable and resistant to wear. It’s ideal for cutting abrasive materials or contaminated wood.

For the Stihl MS210, the Rapid Micro (RM) chain is a popular and versatile choice.

5 Expert Tips for Precision Chain Selection and Maintenance

Now that you have a solid understanding of chainsaw chain basics and the specific requirements of the Stihl MS210, let’s dive into some expert tips for achieving precision in chain selection and maintenance.

Tip #1: Match the Chain to the Task

The first and most crucial step is to select a chain that’s appropriate for the type of cutting you’ll be doing. As I mentioned earlier, different chain designs are optimized for different tasks.

• For General Purpose Cutting: If you’re primarily cutting firewood and doing general yard work, a Rapid Micro (RM) chain is a good choice. It offers a good balance of cutting speed, durability, and safety.
• For Cutting Clean Wood: If you’re cutting clean, softwood lumber, a Rapid Super (RS) chain can provide faster cutting speeds. However, be aware that full-chisel chains are more prone to damage if they come into contact with dirt or debris.
• For Cutting Abrasive Materials or Contaminated Wood: If you’re cutting wood that’s dirty, sandy, or contains nails, a Rapid Duro (RD) chain is the best option. The carbide-tipped teeth are much more resistant to wear than standard steel teeth.

Personal Experience: I once made the mistake of using a Rapid Super (RS) chain to cut some old fence posts that were partially buried in the ground. The chain quickly dulled, and I ended up spending more time sharpening it than cutting. Lesson learned: always match the chain to the task!

Tip #2: Pay Attention to Bar Length

The length of your guide bar determines the number of drive links required for your chain. Using a chain that’s too short or too long can be dangerous and can damage your chainsaw.

Case Study: A friend of mine tried to use a 14-inch chain on his Stihl MS210, which was equipped with a 16-inch bar. The chain was too short to properly engage with the sprocket, and it kept coming off the bar. He ended up damaging the drive links and had to replace the chain.

Best Practice: Always use the correct chain length for your guide bar. Refer to your owner’s manual for the recommended drive link count.

Tip #3: Master the Art of Sharpening

A sharp chain is essential for efficient cutting and safety. A dull chain requires more force to cut, which can increase the risk of kickback and fatigue.

Sharpening Techniques:

• Hand Filing: This is the most common method for sharpening chainsaw chains. Use a round file of the correct diameter (typically 5/32″ for a 3/8″ pitch chain) and a file guide to maintain the correct angle and depth.
• Electric Chain Sharpener: This is a faster and more precise method for sharpening chains. However, it requires more investment in equipment.

Sharpening Frequency: Sharpen your chain whenever it becomes dull. Signs of a dull chain include:

• The chain produces sawdust instead of chips.
• The chain requires more force to cut.
• The chainsaw vibrates excessively.
• The chain pulls to one side.

Personal Tip: I always carry a small file and file guide with me when I’m working in the field. This allows me to touch up the chain quickly and easily, ensuring that I’m always working with a sharp chain.

Tip #4: Proper Chain Maintenance is Key

Regular chain maintenance is crucial for extending the life of your chain and ensuring optimal performance.

Maintenance Tasks:

• Cleaning: Clean your chain regularly to remove dirt, debris, and resin. Use a brush and a solvent (like kerosene or citrus degreaser) to clean the chain.
• Lubrication: Keep your chain properly lubricated. Use a high-quality bar and chain oil. Check the oil level frequently and refill as needed.
• Tensioning: Adjust the chain tension regularly. A properly tensioned chain should be snug on the guide bar but still able to be pulled around by hand.
• Inspection: Inspect your chain regularly for damage, such as cracked or broken teeth, worn drive links, or loose rivets. Replace the chain if you find any significant damage.

Data Insight: In my experience, chains that are properly maintained last significantly longer than chains that are neglected. I’ve seen chains last for several years with proper maintenance, while neglected chains often fail within a few months.

Tip #5: Understand and Mitigate Kickback

Kickback is a dangerous phenomenon that can occur when the tip of the chainsaw bar comes into contact with an object. This can cause the chainsaw to suddenly jump back towards the operator, potentially causing serious injury.

Kickback Prevention:

• Use a Low-Kickback Chain: Chains with bumper drive links or other safety features are designed to reduce the risk of kickback.
• Maintain a Proper Grip: Always hold the chainsaw firmly with both hands.
• Avoid Cutting with the Tip of the Bar: Be aware of the position of the tip of the bar and avoid contacting it with objects.
• Stand to the Side of the Cut: Avoid standing directly behind the chainsaw, as this puts you in the direct path of kickback.
• Be Aware of Your Surroundings: Be aware of any obstacles that could cause kickback, such as branches, rocks, or other debris.

Training is Essential: Proper chainsaw safety training is essential for all chainsaw users. Take a course from a qualified instructor to learn about safe operating procedures and kickback prevention techniques.

While chain selection and maintenance are crucial for felling and bucking trees, wood splitting is another essential aspect of firewood preparation. Let’s briefly discuss some common wood splitting techniques and tools.

Manual Splitting

• Axes: Traditional splitting axes are designed with a heavy head and a wedge-shaped blade for splitting wood along the grain.
• Mauls: A maul is a heavier version of an axe, often with a sledgehammer-like head. It’s used for splitting larger, tougher rounds of wood.
• Wedges: Steel wedges are driven into the wood with a sledgehammer to split particularly difficult rounds.

Techniques:

• Aim for existing cracks: Look for natural cracks in the wood and aim for those when splitting.
• Use a chopping block: A sturdy chopping block provides a stable surface for splitting and protects your axe from hitting the ground.
• Proper stance: Maintain a wide stance for balance and control.

Hydraulic Log Splitters

Hydraulic log splitters use hydraulic pressure to force a wedge through the wood, making splitting much easier and faster.

• Types: Log splitters come in various sizes and configurations, including electric, gas-powered, and tractor-mounted models.
• Tonnage: Log splitters are rated by their splitting force, measured in tons. Choose a splitter with sufficient tonnage for the type of wood you’ll be splitting.
• Safety: Always follow the manufacturer’s safety instructions when operating a log splitter. Wear appropriate safety gear, including eye protection and gloves.

Strategic Advantage: Hydraulic log splitters significantly increase efficiency, especially when dealing with large quantities of wood or tough hardwoods. While they require a larger initial investment, the time and labor savings can be substantial.

Choosing the Right Tool

The best tool for splitting wood depends on the size and type of wood you’re working with, as well as your physical capabilities and budget. For small quantities of easy-to-split wood, an axe or maul may be sufficient. For larger quantities of tough hardwoods, a hydraulic log splitter is a worthwhile investment.

Drying and Stacking Firewood: Ensuring Efficient Burning

Once you’ve cut and split your firewood, it’s essential to dry it properly before burning it.

Drying Methods

• Air Drying: This is the most common and cost-effective method for drying firewood. Stack the wood in a well-ventilated area, away from direct sunlight and rain. Allow the wood to dry for 6-12 months, depending on the climate and wood type.
• Kiln Drying: This is a faster method for drying firewood, but it requires specialized equipment and is more expensive. Kiln-dried firewood typically has a moisture content of less than 20%.

Stacking Techniques

• Elevated Stacks: Stack the firewood on pallets or other supports to keep it off the ground and improve air circulation.
• Criss-Cross Stacking: This method creates a stable stack with good air circulation.
• Leave Space Between Rows: Allow space between rows of firewood to promote air circulation.

Moisture Content Targets: For optimal burning, firewood should have a moisture content of 20% or less. Use a moisture meter to check the moisture content of your firewood before burning it.

Original Case Study: I once experimented with different stacking methods to see which one resulted in the fastest drying time. I found that stacking the wood in a criss-cross pattern on pallets, with space between rows, resulted in the most efficient drying.
