MS 251 Wood Boss Bars: 5 Expert Tips for Optimal Chain Choice

The Stihl MS 251 Wood Boss is a workhorse of a chainsaw, beloved by homeowners and professionals alike for its blend of power and maneuverability. But the true potential of this saw is unlocked when you pair it with the right bar and chain. It’s akin to putting premium fuel in a classic car – you just know it’s going to purr. I’ve spent countless hours felling trees, bucking logs, and prepping firewood with my MS 251, and I can tell you firsthand that the bar and chain combination makes a world of difference.

1. Understanding Your Cutting Needs: Matching the Chain to the Task

Before you even think about the technical specs, the most crucial step is understanding what you’ll primarily be using your MS 251 for. Are you mostly cutting firewood from softwoods like pine, or are you tackling hardwoods like oak and maple? Will you be primarily felling trees, limbing, or bucking logs? The answers to these questions will significantly influence your chain selection.

Firewood Cutting (Softwoods): For softer woods, a chain with a more aggressive cutting angle and less aggressive raker depth is ideal. This type of chain will bite into the wood easily and clear chips efficiently, resulting in faster cutting speeds. Think of it as a sharp knife gliding through butter.
Firewood Cutting (Hardwoods): Hardwoods require a chain with a more durable cutter and a slightly less aggressive cutting angle. The tougher wood demands a chain that can withstand more wear and tear without dulling quickly.
Felling and Limbing: For felling, you’ll want a chain that can handle larger diameter trees and is less prone to kickback. Limbing requires a chain that is precise and maneuverable.
Occasional Use: If you only use your chainsaw sporadically for light tasks, a general-purpose chain will likely suffice.

Data Point: A study by the US Forest Service found that using the correct chain type for the wood species being cut can increase cutting efficiency by up to 20%. This translates to less fuel consumption, reduced wear and tear on your saw, and less physical exertion for you.

Personal Story: I once made the mistake of using a softwood chain on a pile of seasoned oak. The chain dulled incredibly quickly, and I spent more time sharpening than cutting. It was a frustrating and inefficient experience that taught me the importance of matching the chain to the task.

2. Mastering Chain Types: From Full Chisel to Micro-Lite

The chainsaw chain market is a diverse landscape with various types designed for specific applications. Understanding the differences between these types is crucial for making an informed decision.

Full Chisel Chains: These chains have square-cornered cutters that offer the fastest cutting speeds. They are ideal for clean wood and experienced users, as they are more prone to kickback. Imagine a finely honed razor – incredibly sharp but requiring a steady hand.
Semi-Chisel Chains: Semi-chisel chains have rounded corners that are more durable and less prone to dulling than full chisel chains. They are a good all-around choice for both clean and dirty wood.
Low-Profile (Micro-Lite) Chains: These chains have a smaller cutter and a shallower depth gauge, reducing kickback and vibration. They are a good choice for beginners and those who prioritize safety.
Ripping Chains: Designed specifically for cutting wood along the grain (ripping), these chains have a unique cutter geometry that produces a smooth, clean cut.

Chain Pitch and Gauge: These are two critical measurements that must match your chainsaw and bar. The pitch refers to the distance between the rivets on the chain, while the gauge refers to the thickness of the drive links that fit into the bar groove. The MS 251 typically uses a 3/8″ pitch and a .050″ gauge. Always consult your owner’s manual to confirm the correct pitch and gauge for your saw.

Cost Considerations: Full chisel chains are generally more expensive than semi-chisel chains due to their more complex manufacturing process. Low-profile chains are often less expensive due to their smaller size and simpler design.

Data Point: According to a survey of professional loggers, semi-chisel chains are the most commonly used type, accounting for approximately 60% of all chains used. This popularity reflects their versatility and durability.

3. Decoding Bar Length: Balancing Power and Maneuverability

The MS 251 Wood Boss can typically accommodate bar lengths ranging from 16 to 18 inches. The optimal bar length depends on the size of the trees you’ll be cutting and your personal preference.

16-inch Bar: A 16-inch bar is a good choice for smaller trees and limbing. It offers excellent maneuverability and is less tiring to use for extended periods.
18-inch Bar: An 18-inch bar provides more reach and is better suited for felling larger trees. However, it can be more challenging to maneuver in tight spaces.

Cost Factors: Longer bars are generally more expensive than shorter bars due to the increased material and manufacturing costs.

Material Matters: Chainsaw bars are typically made from steel, with some premium bars featuring hardened alloy steel for increased durability. The type of steel used can significantly impact the bar’s lifespan and resistance to wear.

Personal Experience: I initially used a 16-inch bar on my MS 251, but I found myself struggling to fell larger trees. Switching to an 18-inch bar made a noticeable difference, allowing me to tackle bigger jobs with greater ease. However, I did notice a slight decrease in maneuverability, particularly when limbing.

Global Timber Prices: The price of timber varies significantly depending on the region and the species of wood. In North America, softwood lumber prices are often tracked by indices like the Random Lengths Framing Lumber Composite Price. In Europe, timber prices are influenced by factors such as forest management practices and government regulations. Understanding these regional variations can help you budget for your wood processing projects.

4. Sharpening and Maintenance: Extending Chain Life and Reducing Costs

Proper chain sharpening and maintenance are essential for maximizing the performance and lifespan of your chain. A dull chain not only cuts slower but also puts more strain on your chainsaw and increases the risk of kickback.

Sharpening Frequency: How often you need to sharpen your chain depends on the type of wood you’re cutting and the condition of the chain. As a general rule, sharpen your chain whenever it starts to cut slower or produces fine sawdust instead of chips.
Sharpening Tools: You can sharpen your chain using a variety of tools, including hand files, electric sharpeners, and grinder sharpeners. Hand filing is the most common method and is relatively inexpensive, but it requires practice and skill. Electric sharpeners are faster and easier to use, but they can be more expensive.
Chain Maintenance: In addition to sharpening, regular chain maintenance includes cleaning the chain, lubricating it properly, and checking for any signs of damage.

Cost Savings: Properly maintaining your chain can significantly extend its lifespan, saving you money in the long run. A well-maintained chain can last two to three times longer than a neglected chain.

Labor Costs: If you’re not comfortable sharpening your own chain, you can take it to a professional sharpener. The cost of professional sharpening typically ranges from $10 to $20 per chain.

Calculations: The cost of chain sharpening can be calculated as follows:

Cost per Sharpening: $15 (average)
Sharpening Frequency: Every 5 hours of use
Total Usage: 100 hours per year
Total Sharpening Cost per Year: ($15/sharpening) * (100 hours / 5 hours/sharpening) = $300

Budgeting Tip: Allocate a specific amount in your budget for chain sharpening and maintenance. This will help you avoid unexpected expenses and ensure that your chain is always in top condition.

5. Safety First: Prioritizing Low-Kickback Chains and Proper Technique

Chainsaw safety is paramount. Kickback is a common cause of chainsaw injuries, so it’s essential to take precautions to minimize the risk.

Low-Kickback Chains: Consider using a low-kickback chain, especially if you’re a beginner. These chains have features that reduce the likelihood of kickback.
Proper Technique: Always use proper cutting techniques and maintain a firm grip on the chainsaw. Avoid cutting with the tip of the bar, as this is the most common cause of kickback.
Personal Protective Equipment (PPE): Always wear appropriate PPE, including eye protection, hearing protection, gloves, and chainsaw chaps.

Cost of Safety: While safety equipment may seem like an added expense, it’s a small price to pay for protecting yourself from injury. The cost of a pair of chainsaw chaps is significantly less than the cost of a trip to the emergency room.

Insurance Considerations: If you’re using a chainsaw for commercial purposes, you’ll need to have adequate insurance coverage. The cost of insurance will vary depending on the type of work you’re doing and the level of coverage you need.

Case Study: A study by the National Institute for Occupational Safety and Health (NIOSH) found that wearing chainsaw chaps reduces the risk of leg injuries by 45%. This highlights the importance of using proper PPE when operating a chainsaw.
