My Journey with the Stihl MS250

My relationship with the Stihl MS250 started over a decade ago. Back then, I was just getting into firewood processing, helping my grandfather clear fallen trees on his property. The MS250 was his go-to saw, and he swore by its reliability. I remember struggling at first, getting the chain pinched, experiencing excessive vibration, and generally feeling like I was fighting the saw more than working with it.

One day, a seasoned logger friend came by and watched me flailing away. He chuckled and said, “Son, you’ve got a great saw there, but you’re running the wrong setup. It’s like putting street tires on a monster truck.” He then proceeded to explain the nuances of bar and chain selection, and it was a game-changer. He helped me understand how different chain types cut, how bar length affects leverage and control, and how important it is to match the bar and chain to the wood I was cutting.

From that day on, I started experimenting. I tried different bar lengths, chain pitches, and cutter types. I learned the hard way what works and what doesn’t. I’ve spent countless hours sharpening chains, maintaining bars, and fine-tuning my technique. And now, I want to share that knowledge with you, so you can get the most out of your Stihl MS250.

Understanding Bar and Chain Basics

Before diving into my top picks, let’s cover some fundamental concepts. This will help you understand why certain pairings work better than others.

Bar Length

The bar length is the most obvious factor. It’s the length of the guide bar from the tip to where it enters the saw body. Common sizes for the MS250 include 16″, 18″, and even 20″ in some cases.

Shorter Bars (16″): Offer better maneuverability and are ideal for limbing, pruning, and smaller firewood. They also reduce the risk of kickback.
Longer Bars (18″-20″): Provide more reach and are better suited for felling larger trees and bucking bigger logs. However, they require more power and can be more challenging to control, especially for inexperienced users.

My Take: I generally prefer an 18″ bar on my MS250. It offers a good balance of reach and maneuverability for most tasks. However, if I’m doing a lot of limbing or working in tight spaces, I’ll switch to a 16″ bar.

Chain Pitch

The chain pitch is the distance between three consecutive rivets on the chain, divided by two. It’s usually expressed in inches (e.g., .325″, 3/8″). The pitch determines the size of the cutters and the amount of wood each cutter can remove per bite.

.325″ Pitch: A popular choice for mid-sized saws like the MS250. It offers a good balance of cutting speed and smoothness.
3/8″ Pitch: Typically used on larger, more powerful saws. It can remove more wood per bite but requires more power to drive.

Important Note: The MS250 is generally best suited for .325″ pitch chains. While you can technically use a 3/8″ pitch chain, you’ll likely bog down the saw, especially when cutting hardwoods.

Chain Gauge

The chain gauge is the thickness of the drive links that fit into the groove of the guide bar. It’s also expressed in inches (e.g., .050″, .063″). It’s crucial to match the chain gauge to the bar groove width.

.050″ Gauge: The most common gauge for the MS250.
.063″ Gauge: Less common but can be used if your bar is designed for it.

Pro Tip: Always check your bar’s specifications to determine the correct chain gauge. Using the wrong gauge can damage the bar and chain.

Cutter Type

The cutter type refers to the shape and configuration of the cutting teeth on the chain. Different cutter types are designed for different applications.

Full Chisel: These chains have square-cornered cutters that are very aggressive and fast-cutting. They’re best suited for clean wood and experienced users. However, they dull quickly if they hit dirt or debris.
Semi-Chisel: These chains have rounded-corner cutters that are more forgiving and durable than full chisel chains. They’re a good all-around choice for general-purpose cutting.
Low-Profile (Micro-Chisel): These chains have smaller cutters and a lower profile, which reduces kickback. They’re a good choice for beginners and those concerned about safety.

My Recommendation: For most users, a semi-chisel chain is the best option for the MS250. It offers a good balance of cutting speed, durability, and safety.

Tips for Maintaining Your Bar and Chain

No matter which bar and chain pairing you choose, proper maintenance is essential for maximizing performance and extending the lifespan of your equipment.

Sharpening Your Chain

A sharp chain is a safe chain. A dull chain requires more force to cut, which increases the risk of kickback.

How Often to Sharpen: Sharpen your chain every time you refuel your saw, or more often if you notice it’s cutting slower or producing fine sawdust instead of chips.
Sharpening Tools: You can use a file and guide, an electric chain sharpener, or a bench grinder.
Sharpening Angle: Maintain the correct sharpening angle for your chain type. This is usually indicated on the chain itself or in the owner’s manual.
Depth Gauges: Check and adjust the depth gauges (rakers) on your chain. These control the amount of wood each cutter removes per bite. If the depth gauges are too high, the chain won’t cut effectively. If they’re too low, the chain will grab and kickback.

Step-by-Step Guide to Chain Sharpening with a File:

Secure the Saw: Clamp the guide bar in a vise to hold it steady.
Identify the Correct File and Guide: Use a file that matches the pitch and gauge of your chain. Use a filing guide to maintain the correct sharpening angle.
Sharpen Each Cutter: Place the file in the cutter and push it forward, following the angle of the cutter. Use smooth, even strokes. Sharpen each cutter the same number of times.
Check the Depth Gauges: Use a depth gauge tool to check the height of the depth gauges. File them down if necessary.
Test the Chain: After sharpening, test the chain by cutting a small piece of wood. The chain should cut smoothly and produce large chips.

Bar Maintenance

The guide bar is just as important as the chain. A well-maintained bar will help your chain cut more efficiently and last longer.

Cleaning: Clean the bar regularly with a wire brush to remove sawdust and debris.
Filing: File the bar rails to remove any burrs or damage.
Lubrication: Make sure the bar oiler is working properly and that the bar is receiving adequate lubrication.
Bar Groove: Clean the bar groove regularly to remove sawdust and debris. Use a bar groove cleaner or a small screwdriver.
Flipping: Flip the bar regularly to distribute wear evenly.

Chain Lubrication

Proper chain lubrication is crucial for reducing friction and extending the life of your chain and bar.

Bar Oil: Use a high-quality bar and chain oil specifically designed for chainsaws.
Oil Level: Check the oil level frequently and refill as needed.
Oiler Function: Make sure the bar oiler is working properly. You should see a steady stream of oil coming from the bar when the saw is running.
Winter Use: Use a thinner bar oil in cold weather to prevent it from thickening and clogging the oiler.

Storage

Proper storage will help prevent rust and corrosion and keep your bar and chain in good condition.

Cleaning: Clean the bar and chain thoroughly before storing them.
Oiling: Lightly oil the bar and chain to prevent rust.
Sheath: Store the bar in a protective sheath to prevent damage.
Dry Place: Store the saw in a dry place to prevent rust and corrosion.

Safety First: Essential Protective Gear

Before you even think about firing up your chainsaw, make sure you’re wearing the proper protective gear. This is not optional. Chainsaws are powerful tools, and accidents can happen in an instant.

Eye Protection: Wear safety glasses or a face shield to protect your eyes from flying debris.
Hearing Protection: Wear earplugs or earmuffs to protect your hearing from the loud noise of the chainsaw.
Gloves: Wear heavy-duty work gloves to protect your hands from cuts and abrasions.
Chaps: Wear chainsaw chaps to protect your legs from accidental cuts.
Boots: Wear steel-toed boots with good ankle support to protect your feet and ankles.
Helmet: Wear a hard hat to protect your head from falling branches.

Remember: No amount of protective gear can completely eliminate the risk of injury. Always use caution and follow safe operating procedures.

Troubleshooting Common Problems

Even with the right bar and chain and proper maintenance, you may still encounter problems from time to time. Here are some common issues and how to troubleshoot them.

Chain Won’t Cut:
- Possible Causes: Dull chain, incorrect sharpening angle, depth gauges too high, insufficient bar oil, incorrect chain tension.

Beyond the Basics: Advanced Techniques

Once you’ve mastered the fundamentals, you can start exploring more advanced techniques to improve your efficiency and safety.

Felling Techniques

The Hinge: When felling a tree, the hinge is the strip of wood left uncut that controls the direction of the fall. The size and shape of the hinge are crucial for ensuring a safe and controlled fall.
The Back Cut: The back cut is the final cut that severs the tree. It should be made slightly above the level of the horizontal cut and should leave enough wood for the hinge.
Using Wedges: Wedges can be used to help direct the fall of the tree, especially if it’s leaning in the wrong direction.
Escape Route: Always plan an escape route before felling a tree. This should be a clear path away from the tree in case it falls unexpectedly.

Bucking Techniques

Cutting from Above: When bucking logs, it’s often easier and safer to cut from above. This allows you to use gravity to your advantage and reduces the risk of the saw getting pinched.
Cutting from Below: If you need to cut from below, be careful to avoid pinching the saw. Use wedges to support the log and keep the cut open.
Cutting on a Slope: When bucking logs on a slope, always stand uphill from the log to avoid it rolling down on you.

Splitting Techniques

Using a Splitting Maul: A splitting maul is a heavy, wedge-shaped tool used for splitting firewood. It’s more efficient than an axe for splitting large logs.
Using a Wedge and Sledgehammer: For particularly tough logs, you can use a wedge and sledgehammer to split them.
Hydraulic Log Splitters: For high-volume firewood processing, a hydraulic log splitter is a worthwhile investment.

The Environmental Impact of Firewood

It’s important to be aware of the environmental impact of firewood and to take steps to minimize your footprint.

Sustainable Harvesting: Harvest firewood from sustainable sources, such as fallen trees or trees that need to be removed for safety reasons.
Seasoning: Season firewood properly to reduce emissions when burning. Seasoned firewood burns hotter and cleaner than green firewood.
Efficient Burning: Use an efficient wood stove or fireplace to maximize heat output and minimize emissions.
Alternative Fuels: Consider using alternative fuels, such as wood pellets or biofuels, which can be more environmentally friendly than firewood.

The Future of Wood Processing

The wood processing industry is constantly evolving, with new technologies and techniques emerging all the time.
