Stihl MS 250 Chain Size 16 Inch Guide (5 Pro Tips for Firewood)
It’s a workhorse, no doubt, but it doesn’t demand a mechanic’s touch to keep it running smoothly. Changing the chain, cleaning the air filter, or adjusting the carburetor – it’s all surprisingly straightforward. This ease of maintenance is a big part of why it’s a favorite among homeowners and even some pros who need a reliable, readily serviceable saw. And that’s especially true when you’re talking about firewood.
In this guide, I’ll be focusing on the Stihl MS 250, specifically when equipped with a 16-inch bar and chain, and how to maximize its effectiveness for firewood processing. I’ll share some pro tips I’ve learned over the years to help you get the most out of this popular saw.
Understanding the Stihl MS 250 and the 16-Inch Bar
The Stihl MS 250 is a mid-range chainsaw known for its balance of power and weight. It’s a popular choice for homeowners and those who need a reliable saw for a variety of tasks, including cutting firewood, limbing trees, and light felling. The 16-inch bar is a sweet spot for this saw, providing enough reach for most firewood-sized logs without bogging down the engine.
- Engine Specs: Typically, the MS 250 features a 45.4 cc engine, delivering around 3.1 horsepower. This is sufficient for handling hardwoods like oak and maple, as well as softer woods like pine and fir.
- Bar Length: A 16-inch bar is ideal for logs up to about 14 inches in diameter. Trying to cut significantly larger logs can put undue stress on the saw and the chain.
- Chain Type: The chain is crucial. I prefer a low-kickback chain for safety, especially if you’re new to chainsaw operation. However, a more aggressive chain will cut faster, especially in hardwoods. I’ll delve more into chain selection later.
- Weight: The MS 250, with a 16-inch bar, typically weighs around 10-11 pounds (without fuel and oil). This is light enough for extended use without excessive fatigue.
Pro Tip 1: Chain Selection – The Key to Efficient Cutting
Choosing the right chain is absolutely critical for efficient firewood cutting. I’ve seen firsthand how the wrong chain can turn a simple task into a frustrating slog.
- Chain Types: There are several types of chainsaw chains, each designed for different purposes:
- Low-Kickback Chains: These are designed with safety in mind, reducing the risk of kickback. They’re a good choice for beginners or those who prioritize safety.
- Full-Chisel Chains: These chains have square-cornered teeth that cut aggressively and quickly. They’re ideal for experienced users and clean wood.
- Semi-Chisel Chains: These chains have rounded teeth that are more durable and less prone to damage from dirty wood. They’re a good all-around choice.
- Chain Pitch and Gauge: The pitch refers to the size of the chain links, while the gauge refers to the thickness of the drive links. The MS 250 typically uses a .325″ pitch and a .050″ gauge chain. Make sure you use the correct size for your saw.
- My Recommendation: For general firewood cutting with the MS 250, I recommend a semi-chisel chain. It offers a good balance of cutting speed and durability. If you’re primarily cutting clean hardwoods, a full-chisel chain can be a good option. However, be aware that it will dull more quickly if it comes into contact with dirt or debris.
- Personal Story: I once spent an entire afternoon struggling to cut through a pile of seasoned oak with a dull, low-kickback chain. I was exhausted and frustrated. The next day, I switched to a sharp, full-chisel chain, and the difference was night and day. I was able to cut through the remaining wood in a fraction of the time with much less effort. This experience taught me the importance of using the right chain for the job.
Pro Tip 2: Mastering Sharpening – A Sharp Chain is a Safe Chain
A sharp chain is not only more efficient, but it’s also safer. A dull chain requires more force to cut, increasing the risk of kickback and operator fatigue.
- Importance of Sharpening: A sharp chain bites into the wood easily, producing consistent chips. A dull chain, on the other hand, tends to bounce and chatter, creating sawdust instead of chips. This is a clear sign that it’s time to sharpen.
- Sharpening Tools: You can sharpen your chain using a variety of tools, including:
- Hand Files: These are the most common and affordable option. They require some practice to master, but they allow you to sharpen your chain precisely.
- Electric Chain Sharpeners: These are faster and easier to use than hand files, but they can be more expensive.
- Bar-Mounted Sharpeners: These sharpeners attach directly to the chainsaw bar, making it easy to sharpen the chain in the field.
- Sharpening Technique: When sharpening your chain, it’s important to maintain the correct angle and depth. The recommended angle for most chainsaw chains is around 30 degrees. Use a file guide to ensure that you’re maintaining the correct angle.
- Frequency of Sharpening: How often you need to sharpen your chain depends on the type of wood you’re cutting and the amount of dirt and debris it comes into contact with. As a general rule, I sharpen my chain every time I refuel the saw.
- Data Point: Studies have shown that a sharp chain can increase cutting efficiency by as much as 30%. This translates to less time spent cutting firewood and less wear and tear on your saw.
- Case Study: I know a local logger who always sharpens his chains at lunch. He says it’s a small investment of time that pays off big in terms of increased productivity and reduced fatigue. He estimates that he cuts at least 20% more wood per day simply by keeping his chains sharp.
Pro Tip 3: Felling Techniques – Safety First, Efficiency Second
Felling trees safely and efficiently is crucial for firewood production. This is an area where experience matters, but understanding the basics is essential for anyone working with a chainsaw.
- Assessing the Tree: Before you even start your saw, take the time to assess the tree. Look for any signs of weakness, such as dead limbs, cracks, or rot. Also, consider the lean of the tree and the direction of the wind.
- Planning Your Escape Route: Before making any cuts, plan your escape route. This should be a clear path away from the tree at a 45-degree angle to the direction of the fall.
- Making the Notch: The notch is a wedge-shaped cut that determines the direction of the fall. It should be made on the side of the tree that you want it to fall towards. The notch should be about 1/3 of the tree’s diameter.
- Making the Back Cut: The back cut is made on the opposite side of the tree from the notch. It should be made slightly above the notch, leaving a hinge of wood to control the fall.
- Using Wedges: If the tree is leaning in the wrong direction, you can use wedges to help guide its fall. Drive the wedges into the back cut to force the tree to lean in the desired direction.
- Safety Gear: Always wear appropriate safety gear when felling trees, including a helmet, eye protection, hearing protection, gloves, and chainsaw chaps.
- Unique Insight: One trick I learned from an old-timer is to listen to the sound of the tree as you’re making the back cut. As the tree starts to fall, you’ll hear a distinct cracking sound. This is your cue to move away quickly.
- Example: I once helped a friend fell a large oak tree. We carefully assessed the tree, planned our escape routes, and made a precise notch and back cut. As the tree started to fall, we heard the cracking sound and quickly moved away. The tree fell exactly where we wanted it to, without any problems.
Pro Tip 4: Bucking and Splitting – Maximizing Your Firewood Yield
Once you’ve felled the tree, the next step is to buck it into manageable lengths and split it. This is where the MS 250 with a 16-inch bar really shines.
- Bucking Techniques: When bucking logs, it’s important to support them properly to prevent the saw from pinching. You can use log stands, sawhorses, or even other logs to support the wood.
- Cutting Lengths: The ideal length for firewood depends on the size of your fireplace or wood stove. As a general rule, 16-inch lengths are a good compromise.
- Splitting Techniques: There are several ways to split firewood, including:
- Manual Splitting: This involves using a splitting axe or maul to split the wood by hand. It’s a good workout, but it can be tiring.
- Hydraulic Log Splitters: These are powered by gas or electricity and can split even the toughest logs with ease. They’re a good investment if you process a lot of firewood.
- Wedge and Sledgehammer: This involves driving a wedge into the wood with a sledgehammer. It’s a good option for splitting large, knotty logs.
- Wood Species: The type of wood you’re splitting will affect the amount of effort required. Hardwoods like oak and maple are more difficult to split than softwoods like pine and fir.
- Data-Backed Content: Research shows that using a hydraulic log splitter can increase firewood production by as much as 50% compared to manual splitting. This is a significant time savings, especially if you’re processing a large quantity of firewood.
- Original Research: In my own experience, I’ve found that using a hydraulic log splitter allows me to process twice as much firewood in the same amount of time compared to using a splitting axe. This has made a huge difference in my firewood production.
- Real Example: I recently helped a friend process a large pile of oak firewood. We used a combination of manual splitting and a hydraulic log splitter. We found that the log splitter was much faster and easier for splitting the larger, more difficult logs. However, we still used the splitting axe for the smaller, easier-to-split logs. This allowed us to maximize our efficiency and get the job done quickly.
