My First Encounter with the MS250

I remember the day I first laid hands on an MS250 Stihl. It was back in my early days of firewood processing, a time when every swing of the axe felt like a personal battle against the elements. A seasoned logger, a man named Jedediah, saw my struggles and chuckled. “Son,” he said, “you’re fighting the wood. You need a partner, not a weapon.” That partner turned out to be the MS250.

Jedediah, a man who could fell a tree with the grace of a dancer, taught me the ropes. He emphasized not just how to use the saw, but why it worked the way it did. It wasn’t just about pulling the trigger; it was about understanding the engine, the chain, the balance, and the wood itself. This article is my attempt to pass on some of that wisdom, blended with my own experiences, to help you get the most out of your MS250.

Understanding the MS250 Stihl: A Technical Overview

Before we dive into the tips and tricks, let’s get down to the nuts and bolts of the MS250. Knowing the specs is like knowing the playbook before a big game. It allows you to anticipate, adjust, and ultimately, perform better.

Engine Specifications

The heart of the MS250 is its engine, a 45.4 cc (2.77 cu. in.) two-stroke powerhouse. This engine is what separates the MS250 from smaller, less capable saws.

Displacement: 45.4 cc
Power Output: 2.3 kW (3.1 bhp)
Engine Type: Two-stroke
Fuel Tank Capacity: 0.47 liters (15.9 oz.)
Oil Tank Capacity: 0.20 liters (6.8 oz.)

The two-stroke engine design is crucial. It means that every downward stroke of the piston is a power stroke. This design provides a high power-to-weight ratio, a vital factor for a chainsaw. The engine requires a fuel mixture of gasoline and two-stroke oil. Stihl recommends a 50:1 ratio using their high-quality two-stroke oil, which I’ve found to be the most reliable.

Cutting Attachment Specs

The cutting attachment is the business end of the saw. The bar length, chain type, and sprocket all play a crucial role in determining the saw’s cutting performance.

Guide Bar Lengths (Recommended): 16″ (40 cm) or 18″ (45 cm)
Chain Pitch: 0.325″
Chain Gauge: 0.063″
Sprocket Type: Spur
Number of Drive Links: Varies depending on bar length (e.g., 62 for 16″ bar)

I’ve personally found the 16″ bar to be the sweet spot for most tasks. It offers a good balance between maneuverability and cutting capacity. However, if you’re consistently dealing with larger diameter logs, the 18″ bar might be a better choice. The 0.325″ chain pitch is a common size, providing a good balance of speed and durability. The 0.063″ gauge refers to the thickness of the drive links, which fit into the guide bar groove. Using the correct chain gauge is essential for proper chain lubrication and cutting performance.

Weight and Dimensions

Weight and dimensions are important factors to consider, especially if you’ll be using the saw for extended periods.

Weight (without fuel, guide bar, and chain): 4.6 kg (10.1 lbs.)
Overall Length (with 16″ guide bar): Approximately 30 inches

The MS250 is relatively lightweight for its power, making it easier to handle and maneuver. However, even a “lightweight” chainsaw can become tiring after a few hours of use. Proper technique and regular breaks are essential to avoid fatigue and potential injuries.

Additional Features

The MS250 comes equipped with several features designed to improve user comfort and safety.

Stihl Quick Chain Tensioning (B) System: Allows for easy, tool-free chain adjustment.
Master Control Lever: Combines choke, starting throttle lock, and on/off switch into one easy-to-use control.
Anti-Vibration System: Reduces operator fatigue by minimizing vibration.
Chain Brake: Stops the chain in milliseconds in case of kickback.

I’ve found the Quick Chain Tensioning system to be particularly useful in the field. It allows me to quickly adjust the chain without having to fumble with tools. The Master Control Lever is also a convenient feature, simplifying the starting and stopping process. The anti-vibration system is a lifesaver on long days, reducing the strain on my hands and arms. And of course, the chain brake is a critical safety feature that should always be engaged when the saw is not in use.

5 Pro Tips for Smooth Wood Cutting with Your MS250

Now that we’ve covered the technical aspects of the MS250, let’s move on to the practical tips that will help you cut wood like a pro. These tips are based on my own experiences, as well as the wisdom I’ve gleaned from seasoned loggers and arborists over the years.

1. Mastering Chain Maintenance: The Key to Efficiency

A dull chain is like a dull knife – it’s frustrating, inefficient, and potentially dangerous. A sharp chain, on the other hand, bites into the wood with ease, making cutting faster, smoother, and safer.

Why Chain Maintenance Matters:

Increased Cutting Speed: A sharp chain cuts through wood much faster than a dull one.
Reduced Strain on the Saw: A dull chain forces the engine to work harder, leading to increased wear and tear.
Improved Fuel Efficiency: A sharp chain requires less power to cut, resulting in better fuel economy.
Enhanced Safety: A dull chain is more likely to kick back, increasing the risk of injury.
Cleaner Cuts: A sharp chain produces cleaner, more precise cuts, which is especially important for woodworking projects.

How to Sharpen Your Chain:

There are two main methods for sharpening a chainsaw chain: using a file or using a chain grinder. I prefer using a file for routine maintenance, as it’s quick, easy, and can be done in the field. A chain grinder is better for more significant sharpening or repairing damaged chains.

Filing Technique:

Secure the Saw: Place the chainsaw on a stable surface and engage the chain brake.
Choose the Right File: Use a round file with the correct diameter for your chain’s pitch (usually 5/32″ for a 0.325″ pitch chain). You’ll also need a flat file for adjusting the depth gauges.
Position the File: Hold the file at the correct angle, typically 30 degrees relative to the cutter, and at the proper depth. Many filing guides are available to help you maintain the correct angles.
File Each Cutter: File each cutter evenly, using smooth, consistent strokes. File from the inside of the cutter to the outside. Count the number of strokes you use on each cutter to ensure they are all sharpened equally.
Adjust Depth Gauges: After sharpening the cutters, check the depth gauges (the small metal tabs in front of each cutter). These gauges control how deeply the cutter bites into the wood. If the depth gauges are too high, the chain will cut aggressively but will also be more prone to kickback. If they are too low, the chain will not cut effectively. Use a flat file to lower the depth gauges as needed, following the manufacturer’s recommendations.
Rotate the Chain: Release the chain brake and rotate the chain to sharpen the next cutter. Repeat the process until all cutters have been sharpened.
Inspect and Clean: After sharpening, inspect the chain for any damage or wear. Clean the chain and guide bar thoroughly, removing any sawdust or debris.

Chain Grinder Technique:

Secure the Chain Grinder: Mount the chain grinder on a stable surface.
Adjust the Grinder: Adjust the grinder to the correct angles and depth settings for your chain. Refer to the grinder’s manual for specific instructions.
Grind Each Cutter: Carefully grind each cutter, using light, consistent pressure. Avoid overheating the cutters, as this can damage the metal.
Adjust Depth Gauges: After grinding, check and adjust the depth gauges as needed.
Inspect and Clean: Inspect the chain for any damage or wear. Clean the chain and guide bar thoroughly.

Frequency of Sharpening:

How often you need to sharpen your chain depends on the type of wood you’re cutting and how often you use the saw. As a general rule, I sharpen my chain after every few tanks of fuel, or whenever I notice a decrease in cutting performance. If you hit dirt or rocks, you’ll need to sharpen the chain immediately.

Pro Tip: Invest in a good quality filing kit or chain grinder. A sharp chain is an investment in your safety and efficiency.

2. Choosing the Right Bar and Chain: Matching the Tool to the Task

The MS250 is a versatile saw, but it’s not a one-size-fits-all solution. Choosing the right bar and chain for the job is crucial for optimal performance and safety.

Bar Length:

As mentioned earlier, the MS250 is typically equipped with a 16″ or 18″ bar. The best choice depends on the size of the wood you’ll be cutting.

16″ Bar: Ideal for smaller trees, branches, and firewood. It’s more maneuverable and easier to control, making it a good choice for beginners.
18″ Bar: Better suited for larger diameter logs. It allows you to cut through thicker wood in a single pass, saving time and effort.

Chain Type:

There are several different types of chainsaw chains available, each designed for specific applications.

Full Chisel Chains: These chains have square-cornered cutters that are very aggressive and cut quickly. However, they are also more prone to kickback and require more frequent sharpening. I recommend these for experienced users only.
Semi-Chisel Chains: These chains have rounded-corner cutters that are less aggressive than full chisel chains but are also more durable and less prone to kickback. They are a good choice for general-purpose cutting.
Low-Kickback Chains: These chains are designed with features that reduce the risk of kickback. They are a good choice for beginners or anyone who is concerned about safety.

Matching Bar and Chain:

When choosing a bar and chain, make sure they are compatible with your saw. The bar must be the correct length and have the correct mounting pattern for your saw. The chain must have the correct pitch, gauge, and number of drive links for your bar. Refer to your saw’s owner’s manual for specific recommendations.

Pro Tip: Consider having multiple bars and chains on hand, each suited for different tasks. This will allow you to quickly adapt to changing conditions and maximize your cutting efficiency.

3. Mastering Cutting Techniques: Precision and Efficiency

Knowing how to properly operate a chainsaw is just as important as having a sharp chain. Proper cutting techniques can help you maximize the saw’s power, reduce strain, and avoid dangerous situations.

Basic Cutting Techniques:

Felling: Felling a tree involves making a series of precise cuts to control the direction of the fall. This is a complex process that requires experience and knowledge of tree felling techniques. I highly recommend taking a professional tree felling course before attempting to fell a tree on your own.
Limbing: Limbing involves removing branches from a felled tree. This can be done using a variety of techniques, depending on the size and position of the branches. Always stand on the uphill side of the log and work from the base of the tree towards the top.
Bucking: Bucking involves cutting a log into smaller pieces. This is typically done to prepare firewood or lumber. Use proper support techniques to prevent the log from pinching the saw.

Advanced Cutting Techniques:

Boring Cut: A boring cut is used to remove a section of wood from the center of a log. This technique is often used to relieve tension in the wood and prevent pinching.
Plunge Cut: A plunge cut is used to cut into the wood at an angle. This technique is often used to create notches or to remove sections of wood that are difficult to reach with a standard cut.

Tips for Smooth Cutting:

Keep the Saw Moving: Don’t force the saw through the wood. Let the chain do the work.
Use the Correct Cutting Angle: Maintain the correct cutting angle to maximize the saw’s efficiency.
Avoid Pinching: Pinching occurs when the wood closes in on the saw blade, causing it to bind. Use proper support techniques to prevent pinching.
Take Breaks: Chainsaw use can be physically demanding. Take regular breaks to avoid fatigue.

Pro Tip: Practice your cutting techniques on scrap wood before tackling larger projects. This will help you develop your skills and build confidence.

4. Fuel and Lubrication: Feeding the Beast

The MS250, like any engine, needs the right fuel and lubrication to run smoothly and reliably.

Fuel:

The MS250 requires a mixture of gasoline and two-stroke oil. Stihl recommends a 50:1 ratio using their high-quality two-stroke oil. Using the correct fuel mixture is essential for preventing engine damage.

Why Use Two-Stroke Oil:

Two-stroke oil is specifically designed to lubricate the engine’s internal components in a two-stroke engine. Unlike four-stroke engines, two-stroke engines don’t have a separate oil reservoir. Instead, the oil is mixed with the fuel and burned along with it.

Mixing Fuel:

Always mix fuel in a well-ventilated area. Use a clean fuel can and a measuring container to ensure the correct ratio. Mix only the amount of fuel you need for the day to avoid fuel degradation.

Fuel Storage:

Store fuel in a cool, dry place away from direct sunlight. Use a fuel stabilizer to prevent the fuel from going stale.

Chain Oil:

Chain oil is used to lubricate the chain and guide bar. This reduces friction, prevents wear, and helps to keep the chain cool.

Types of Chain Oil:

There are several different types of chain oil available, including mineral-based oils, vegetable-based oils, and synthetic oils. I prefer using a high-quality bar and chain oil specifically designed for chainsaws.

Applying Chain Oil:

The MS250 has an automatic chain oiler that dispenses oil onto the chain and guide bar. Check the oil level regularly and refill as needed. Adjust the oiler to provide adequate lubrication for the cutting conditions.

Pro Tip: Use a high-quality fuel and chain oil to prolong the life of your saw and ensure optimal performance.

5. Safety First: Protecting Yourself and Others

Chainsaws are powerful tools that can be dangerous if not used properly. Safety should always be the top priority when operating a chainsaw.

Kickback:

Kickback is a sudden, violent reaction that occurs when the tip of the saw blade contacts a solid object or is pinched. Kickback can cause the saw to fly back towards the operator, potentially causing serious injury.

Preventing Kickback:

Use a Low-Kickback Chain: Low-kickback chains are designed with features that reduce the risk of kickback.
Avoid Contact with Solid Objects: Be careful to avoid contacting solid objects with the tip of the saw blade.
Maintain a Firm Grip: Maintain a firm grip on the saw with both hands.
Stand to the Side: Stand to the side of the cutting path to avoid being hit by the saw in case of kickback.
