The Stihl MS 250 is a popular chainsaw for homeowners and light-duty commercial use. Getting the right chain size and understanding how to optimize its performance is crucial for safety, efficiency, and the longevity of your saw. Let’s get into the nitty-gritty.

Understanding the MS 250: A Chainsaw’s Heart and Soul

Before we dive into chain sizes, let’s quickly revisit why the MS 250 is so well-regarded. It strikes a good balance between power, weight, and affordability, making it a versatile tool for a variety of tasks, from felling small trees to bucking firewood. It’s a saw that many people, including myself, have relied on for years.

Tip 1: Decoding Chain Specifications: What You Need to Know

Selecting the right chain for your MS 250 isn’t just about grabbing the first one you see on the shelf. You need to understand the key specifications:

Pitch: This is the distance between any three consecutive rivets on the chain divided by two. The MS 250 typically uses a 3/8″ low-profile pitch. Using the correct pitch ensures the chain meshes properly with the sprocket and bar.
Gauge: This is the thickness of the drive links – the part of the chain that fits into the guide bar groove. The MS 250 generally uses a .050″ gauge. A mismatch here can lead to chain derailment and damage.
Drive Link Count: This is the number of drive links on the chain. The correct number depends on the length of the guide bar you’re using. A 16-inch bar on an MS 250 typically requires around 55 drive links, while an 18-inch bar needs around 61.
Chain Type: The type of chain (e.g., low-kickback, full chisel, semi-chisel) affects cutting speed and safety. For general use, a low-kickback chain is a safe and versatile choice. For faster cutting on clean wood, a full chisel chain is preferred.

My Experience: I remember once trying to force a chain with the wrong gauge onto my MS 250. It was a recipe for disaster. The chain kept jumping off, and I nearly damaged the bar. Lesson learned: always double-check the specs!

Actionable Step: Consult your MS 250 owner’s manual for the recommended chain specifications. If you’re unsure, take your saw to a reputable dealer and ask for assistance.

Tip 2: Measuring Your Chain: A Practical Guide

Knowing the specifications is one thing, but verifying them is another. Here’s how to measure your chain:

Pitch: Use a ruler or calipers to measure the distance between three rivets. Divide that number by two.
Gauge: Use a gauge measuring tool or calipers to measure the thickness of a drive link.
Drive Link Count: Count the number of drive links on the chain. This is straightforward but can be tedious.

Data Point: According to Stihl’s technical data, using the wrong chain pitch can reduce cutting efficiency by up to 20% and increase the risk of chain breakage by 15%.

Tip 3: Choosing the Right Chain Type: Matching the Chain to the Task

The type of chain you choose can significantly impact your cutting performance and safety. Here’s a breakdown:

Low-Kickback Chains: These chains have guard links that reduce the risk of kickback. They’re ideal for beginners and for cutting in situations where kickback is a concern.
Full Chisel Chains: These chains have square-cornered cutters that provide the fastest cutting speed. They’re best suited for experienced users and for cutting clean wood.
Semi-Chisel Chains: These chains have rounded corners that make them more forgiving than full chisel chains. They’re a good compromise between cutting speed and durability.
Ripping Chains: These chains are designed for cutting wood parallel to the grain. They’re used in sawmills and for making planks.

My Experience: When I first started using chainsaws, I always used low-kickback chains. As I gained experience, I switched to full chisel chains for faster cutting. However, I always kept a low-kickback chain on hand for situations where safety was paramount.

Actionable Step: Consider the type of wood you’ll be cutting and your skill level when choosing a chain type. If you’re unsure, start with a low-kickback chain.

Tip 4: Chain Maintenance: Sharpening, Cleaning, and Lubrication

Proper chain maintenance is essential for optimal cutting performance and chain longevity. Here are some key practices:

Sharpening: A sharp chain cuts faster, safer, and with less effort. Sharpen your chain regularly using a file, a grinder, or a sharpening kit.
Cleaning: Keep your chain clean by removing sawdust and debris after each use. Use a brush or compressed air to clean the chain.
Lubrication: Always use chain oil to lubricate the chain and bar. This reduces friction and wear. Check the oil level frequently and refill as needed.
Tensioning: Maintain proper chain tension to prevent the chain from derailing or binding. The chain should be snug against the bar but still able to be pulled around by hand.

Data Point: Studies have shown that a properly sharpened chain can increase cutting speed by up to 30% and reduce fuel consumption by 10%.

My Experience: I’ve seen firsthand the difference that proper chain maintenance can make. A sharp, clean, and well-lubricated chain cuts through wood like butter, while a dull, dirty, and dry chain struggles and strains the saw.

Actionable Step: Develop a regular chain maintenance routine. Sharpen the chain before each use, clean it after each use, and lubricate it frequently.

Tip 5: Safety First: Essential Precautions for Chainsaw Use

Chainsaws are powerful tools that can be dangerous if not used properly. Here are some essential safety precautions:

Wear appropriate personal protective equipment (PPE): This includes a helmet, eye protection, hearing protection, gloves, chaps, and boots.
Read and understand the owner’s manual: Familiarize yourself with the saw’s features, controls, and safety instructions.
Inspect the saw before each use: Check for any loose parts, damage, or leaks.
Start the saw on the ground or on a stable surface: Never drop-start the saw.
Maintain a firm grip on the saw with both hands: Keep your thumb wrapped around the handle.
Keep your body balanced and your feet firmly planted: Avoid overreaching or cutting above shoulder height.
Be aware of your surroundings: Watch out for obstacles, power lines, and other people.
Never cut directly overhead: This is extremely dangerous and can lead to serious injury.
Use proper cutting techniques: Avoid kickback by cutting with the bottom of the bar and keeping the nose of the bar away from objects.
Take breaks to avoid fatigue: Fatigue can lead to errors in judgment and accidents.

My Experience: I’ve had a few close calls over the years. One time, I was cutting a tree that was under tension, and it snapped back unexpectedly. Fortunately, I was wearing my PPE, and I was able to avoid serious injury.

Actionable Step: Always prioritize safety when using a chainsaw. Wear PPE, read the owner’s manual, inspect the saw before each use, and use proper cutting techniques.
