Chain for Stihl MS170: Choosing the Best (5 Pro Tips)

The global firewood market is booming, driven by rising energy costs and a renewed interest in sustainable heating solutions. According to recent reports, the global firewood market is projected to reach \$4.5 billion by 2027, with a compound annual growth rate (CAGR) of 3.2% from 2020 to 2027. This increased demand puts pressure on efficient and effective wood processing, and the right chainsaw chain is crucial. So, let’s get into it!

Understanding the Importance of the Right Chain

Choosing the correct chain for your Stihl MS170 isn’t just about making the saw run; it’s about safety, efficiency, and the lifespan of your equipment. A mismatched chain can lead to:

Increased Kickback Risk: A chain that doesn’t properly fit the bar and sprocket can increase the chance of kickback, a dangerous situation where the saw suddenly thrusts backward.
Reduced Cutting Efficiency: An incorrect chain type might not be optimized for the type of wood you’re cutting, leading to slower cutting and increased fuel consumption.
Premature Wear and Tear: Using the wrong chain can put undue stress on the saw’s engine, bar, and sprocket, leading to costly repairs or replacements.
Safety Hazards: Improper chain tension and fit can cause the chain to derail, posing a significant safety risk.

I’ve seen firsthand the consequences of using the wrong chain. One time, a friend borrowed my MS170 with what he thought was a compatible chain. He ended up with a severely damaged bar and a very close call due to increased kickback. That experience cemented the importance of knowing your chain specs!

Key Concepts: Chain Terminology and Specifications

Before we get into the pro tips, let’s define some key terms that will help you understand chain specifications:

Pitch: The distance between any three consecutive rivets on the chain, divided by two. Common pitches are 3/8″ low profile (.375″), .325″, and 3/8″ (.375″). The MS170 typically uses a 3/8″ low profile (.375″) pitch.
Gauge: The thickness of the drive links, which fit into the groove of the guide bar. Common gauges are .043″, .050″, .058″, and .063″. The MS170 typically uses a .050″ gauge.
Drive Links: The number of drive links determines the overall length of the chain. This number is crucial for fitting the chain to your specific bar length.
Chain Type: Different chain types are designed for different purposes, such as ripping, cross-cutting, or general use. Common types include chisel, semi-chisel, and low-kickback chains.
Rivet: The metal fasteners that hold the chain segments together.
Cutter: The cutting teeth on the chain. The shape and design of the cutter affect the chain’s cutting performance.
Tie Straps: The metal links that connect the cutters and drive links.

Why are these important? The pitch dictates what sprocket the chain will fit on. The gauge ensures the drive links properly engage with the guide bar. Drive link count is crucial for the chain to completely wrap around the bar. Using a chain with the wrong specifications is like trying to fit a square peg in a round hole – it just won’t work!

Pro Tip #1: Identify Your Stihl MS170’s Bar Length and Chain Specifications

This is the most crucial step! You need to know your bar length and the correct chain specifications for your MS170. The easiest way is to consult your owner’s manual. If you don’t have the manual, you can usually find the information printed on the guide bar itself. Look for markings that indicate the chain pitch, gauge, and the number of drive links.

Here’s how to find the information:

Check the Guide Bar: Most guide bars have the chain specifications stamped directly onto them. Look for numbers and symbols like “3/8LP .050” or similar.
Consult the Owner’s Manual: The owner’s manual will have the recommended chain specifications for your MS170.
Use the Stihl Website: Stihl’s website has a tool that allows you to look up the correct chain for your chainsaw model.
Ask a Professional: If you’re still unsure, take your saw to a local Stihl dealer. They can help you identify the correct chain specifications.

Example: Let’s say your guide bar is marked “3/8LP .050 50DL”. This means you need a chain with a 3/8″ low profile pitch, a .050″ gauge, and 50 drive links.

Why this matters: Using the wrong number of drive links means the chain will either be too loose (and likely derail) or too tight (and impossible to install). Using the wrong pitch or gauge will prevent the chain from even fitting on the bar and sprocket.

Pro Tip #2: Choose the Right Chain Type for Your Cutting Needs

Not all chainsaw chains are created equal. Different chain types are designed for different cutting tasks. Here are some common types:

Chisel Chains: These chains have square-cornered cutters that are very aggressive and efficient for cutting clean wood. They are best suited for experienced users and require more frequent sharpening.
Semi-Chisel Chains: These chains have rounded-cornered cutters that are more forgiving and easier to sharpen than chisel chains. They are a good all-around choice for general use.
Low-Kickback Chains: These chains are designed to reduce the risk of kickback, making them a safer option for beginners and occasional users. They typically have bumper links or guard links that help prevent the chain from grabbing and kicking back.
Ripping Chains: These chains are designed for cutting wood along the grain, such as when milling lumber. They have a different cutter angle than cross-cutting chains, which makes them more efficient for ripping.

Which chain type is best for your MS170?

For most users of the Stihl MS170, I recommend a low-kickback, semi-chisel chain. This type offers a good balance of cutting performance, ease of sharpening, and safety. It’s a great choice for general firewood cutting, pruning, and light tree felling.

My personal experience: I used to favor chisel chains for their aggressive cutting speed, but I quickly realized they weren’t the best choice for all situations. When cutting dirty or knotty wood, they dull much faster than semi-chisel chains. Now, I primarily use semi-chisel chains for most of my firewood cutting needs.

Consider your wood type: If you’re primarily cutting softwoods like pine or fir, a chisel chain might be a good option. However, if you’re cutting hardwoods like oak or maple, a semi-chisel chain will likely hold its edge longer.

Pro Tip #3: Invest in a High-Quality Chain

While it might be tempting to save money by buying a cheap, off-brand chain, I strongly advise against it. High-quality chains are made from better materials, have tighter tolerances, and are heat-treated for improved durability. This translates to:

Longer Lifespan: High-quality chains will last longer than cheap chains, saving you money in the long run.
Improved Cutting Performance: High-quality chains will cut faster and more efficiently, reducing strain on your saw and your body.
Increased Safety: High-quality chains are less likely to break or derail, reducing the risk of injury.
Better Sharpening: High-quality chains are easier to sharpen and will hold their edge longer.

Recommended Brands:

Stihl: Stihl chains are specifically designed for Stihl chainsaws and are known for their quality and performance.
Oregon: Oregon is a well-respected brand that produces high-quality chains for a variety of chainsaw models.
Carlton: Carlton chains are another reputable brand that offers good performance and durability.

Cost vs. Value: A high-quality chain might cost 20-30% more than a cheap chain, but it will likely last twice as long and provide a much better cutting experience. Think of it as an investment in your safety and the longevity of your chainsaw.

Case Study: I once compared a cheap, no-name chain to an Oregon chain on my MS170. The cheap chain dulled after only a few cuts and stretched excessively. The Oregon chain, on the other hand, lasted through several hours of cutting and required much less frequent sharpening. The difference in performance was night and day.

Pro Tip #4: Master Chain Sharpening Techniques

A sharp chain is a safe chain. A dull chain requires more force to cut, which increases the risk of kickback and puts unnecessary strain on your saw. Regular chain sharpening is essential for maintaining optimal performance and safety.

Sharpening Tools:

Round File and File Guide: This is the most common method for sharpening chainsaw chains. A round file is used to sharpen the cutters, and a file guide helps maintain the correct angle and depth.
Electric Chain Sharpener: An electric chain sharpener can quickly and accurately sharpen chainsaw chains. However, it requires more skill to use properly and can be more expensive than a round file and file guide.
Handheld Chain Sharpener: These sharpeners are portable and easy to use, making them a good option for sharpening chains in the field.

Sharpening Procedure:

Secure the Chain: Place the chainsaw in a vise or clamp to hold it securely.
Identify the Correct Angle: Use a file guide to determine the correct sharpening angle for your chain type.
Sharpen Each Cutter: Using a round file, sharpen each cutter using smooth, consistent strokes. Maintain the correct angle and depth.
Check the Depth Gauges: Use a depth gauge tool to check the height of the depth gauges. File them down if necessary.
Rotate the Chain: Rotate the chain and repeat the sharpening process for each cutter.

Sharpening Frequency:

How often you need to sharpen your chain depends on the type of wood you’re cutting and how often you use your saw. As a general rule, you should sharpen your chain every time you refuel your saw, or whenever you notice that it’s cutting slower or requiring more force.

Troubleshooting:

Chain Cuts at an Angle: This usually indicates that one side of the chain is duller than the other.
Chain Smokes: This indicates that the chain is very dull and is generating heat due to friction.
Chain Pulls to One Side: This usually indicates that the cutters on one side are shorter than the cutters on the other side.

Data Point: Studies show that a properly sharpened chain can increase cutting efficiency by up to 30%. This translates to less fuel consumption, less strain on your saw, and faster cutting times.

My personal tip: I always keep a small file and file guide in my chainsaw kit so I can touch up the chain in the field if needed. A few quick strokes with the file can make a big difference in cutting performance.

Pro Tip #5: Maintain Proper Chain Tension and Lubrication

Proper chain tension and lubrication are essential for the safe and efficient operation of your chainsaw.

Chain Tension:

Too Loose: A chain that is too loose can derail, causing damage to the saw and posing a safety risk.
Too Tight: A chain that is too tight can cause excessive wear and tear on the bar, sprocket, and engine.

Checking Chain Tension:

Turn off the Saw: Always turn off the saw before checking chain tension.
Wear Gloves: Wear gloves to protect your hands from the sharp chain.
Lift the Chain: Lift the chain in the middle of the guide bar. The chain should lift slightly, but not come completely off the bar.
Adjust Tension: If the chain is too loose or too tight, adjust the tension using the tensioning screw on the side of the saw.

Lubrication:

Use Bar and Chain Oil: Always use a high-quality bar and chain oil to lubricate the chain.
Check Oil Level: Check the oil level frequently and refill as needed.
Clean the Bar and Chain: Regularly clean the bar and chain to remove dirt and debris.

Why is lubrication important?

Proper lubrication reduces friction between the chain and the bar, which prevents overheating and premature wear. It also helps to keep the chain clean and free of debris.

Troubleshooting:

Chain Smokes: This can indicate that the chain is not being properly lubricated.
Bar Turns Blue: This indicates that the bar is overheating due to lack of lubrication.

Budgeting Considerations:

Bar and chain oil is an ongoing expense, so it’s important to factor it into your budget. You can save money by buying oil in bulk.

Real Example: I once neglected to check the oil level on my chainsaw and ended up running it dry. The bar overheated and turned blue, and the chain was severely damaged. It was a costly mistake that could have been avoided with a little bit of preventative maintenance.

Additional Considerations

Beyond the five pro tips above, here are some additional factors to consider when choosing a chain for your Stihl MS170:

User Skill Level: If you’re a beginner, choose a low-kickback chain and take the time to learn proper cutting techniques.
