Understanding Chainsaw Chains: A Primer

Before diving into specific recommendations for your Stihl MS250, let’s cover the basics of chainsaw chains. Think of it as Chain 101.

Key Concepts:

Pitch: The distance between any three consecutive rivets divided by two. This determines the chain’s compatibility with your chainsaw’s drive sprocket and guide bar.
Gauge: The thickness of the drive links, which fit into the groove of the guide bar. It’s crucial to match the gauge to your bar’s specification.
Drive Links: The number of these links determines the length of the chain needed for your specific guide bar.
Cutter Type: This is where things get interesting! You have full chisel, semi-chisel, and low-profile (also called micro-chisel) cutters, each with its own strengths and weaknesses.

Why These Concepts Matter:

Using the wrong pitch or gauge chain can damage your chainsaw and potentially cause serious injury. Understanding cutter types will help you choose a chain that’s best suited for the type of wood you’re cutting and your skill level.

Pro Tip 1: Knowing Your Stihl MS250 Specifications

Before you even think about buying a new chain, you need to know the specs for your Stihl MS250. This isn’t optional. Grab your owner’s manual (or find it online) and look for the following:

Pitch: The MS250 typically uses a 3/8″ low-profile pitch chain.
Gauge: The standard gauge is .050″.
Drive Link Count: This depends on the length of your guide bar. Common lengths for the MS250 are 16″ and 18″, requiring different drive link counts. A 16″ bar usually needs 55 drive links, while an 18″ bar needs 61. Always double-check!

Real-World Example:

I once helped a friend who bought a chain online without checking his saw’s specs. He ended up with a chain that was the wrong gauge, and it wouldn’t fit properly on the guide bar. He tried to force it, which could have damaged his chainsaw. Learn from his mistake!

Pro Tip 2: Choosing the Right Cutter Type for Your Needs

This is where personal preference and the type of wood you’re cutting come into play.

Full Chisel: These chains have square-cornered cutters that are extremely sharp and fast-cutting. They’re ideal for clean wood, like pine or fir, and for experienced users who can handle the aggressive cutting action. However, they dull quickly in dirty or frozen wood and are more prone to kickback.
Semi-Chisel: These chains have rounded corners on the cutters, making them more durable and less prone to dulling. They’re a good all-around choice for cutting a variety of wood types, including hardwood and slightly dirty wood. They are also less prone to kickback.
Low-Profile (Micro-Chisel): These chains have small, rounded cutters and are designed for safety. They’re the least aggressive cutting type but are also the most resistant to kickback. They’re a good choice for beginners or for cutting small branches and limbs.

My Experience:

I’ve used all three types of chains on my Stihl MS250. For felling small pines, I prefer a full chisel chain for its speed. But for cutting firewood, which often includes hardwood and wood that’s been sitting on the ground, I usually opt for a semi-chisel chain. It’s a good balance of cutting speed and durability.

Data Point:

Studies have shown that full chisel chains can cut up to 20% faster than semi-chisel chains in clean wood. However, they also require more frequent sharpening, increasing maintenance time and costs.

Pro Tip 3: Considering Chain Brands and Features

Several reputable brands manufacture chainsaw chains that are compatible with the Stihl MS250. Here are a few of the most popular:

Stihl: Stihl chains are known for their quality and durability. They’re designed to work perfectly with Stihl chainsaws, ensuring optimal performance.
Oregon: Oregon is a leading manufacturer of chainsaw chains and guide bars. They offer a wide range of chains to suit different needs and budgets.
Husqvarna: While Husqvarna is a competitor to Stihl, their chains are also high-quality and compatible with the MS250.

Beyond Brands: Look for These Features:

Chrome Plating: Chrome-plated cutters are more resistant to wear and corrosion.
LubriTec™: Oregon’s LubriTec™ system helps to keep the chain and guide bar lubricated, reducing friction and extending their lifespan.
Bumper Drive Links: These links help to reduce kickback.

Case Study:

A local firewood producer I know switched from using generic chains to Oregon chains with LubriTec™. He reported that his chains lasted significantly longer, reducing his downtime and saving him money on replacements.

Pro Tip 4: Sharpening Your Chain Like a Pro

No matter how good your chain is, it will eventually dull. A dull chain is not only inefficient; it’s also dangerous. A sharp chain bites into the wood, while a dull chain bounces and can cause kickback.

Essential Tools for Sharpening:

Chainsaw File: A round file that matches the pitch of your chain.
File Guide: A tool that helps you maintain the correct filing angle.
Depth Gauge Tool: Used to adjust the depth gauges (rakers) on your chain.
Vise: To hold the chainsaw securely while you’re sharpening.

Step-by-Step Sharpening Guide:

Secure the Chainsaw: Place the chainsaw in a vise to hold it securely.
Identify the Sharpest Cutter: Use this as a reference point for sharpening all the other cutters.
File the Cutters: Using the correct size round file and a file guide, sharpen each cutter to the same angle and length. File from the inside out, following the existing angle of the cutter.
Adjust the Depth Gauges: Use a depth gauge tool to ensure that the depth gauges (rakers) are at the correct height. If they’re too high, the chain won’t cut properly.
Test the Chain: After sharpening, test the chain by cutting a piece of wood. It should cut smoothly and efficiently.

Troubleshooting:

Chain Cuts at an Angle: This usually means that one side of the chain is sharper than the other. Re-sharpen the duller side.
Chain Smokes or Burns the Wood: This indicates that the chain is too dull or that the depth gauges are too high. Sharpen the chain or adjust the depth gauges.

Pro Tip 5: Chain Maintenance and Storage

Proper maintenance and storage can significantly extend the life of your chainsaw chain.

Key Maintenance Practices:

Keep the Chain Lubricated: Use a high-quality bar and chain oil to keep the chain lubricated. This reduces friction and wear.
Clean the Chain Regularly: Remove sawdust and debris from the chain after each use.
Check the Chain Tension: Make sure the chain is properly tensioned. A loose chain can derail and cause damage.
Inspect the Chain for Damage: Look for cracks, broken cutters, or other signs of damage. Replace the chain if necessary.

Storage Tips:

Clean and Oil the Chain: Before storing the chainsaw, clean and oil the chain to prevent rust and corrosion.
Store the Chainsaw in a Dry Place: Store the chainsaw in a dry place to prevent moisture damage.
Use a Chain Guard: Use a chain guard to protect the chain from damage during storage.

Personal Story:

I once left my chainsaw outside in the rain for a week. When I went to use it, the chain was covered in rust. I had to spend hours cleaning and sharpening it before I could use it again. Lesson learned: always store your chainsaw properly!
