MS261 Chain Upgrade Tips (3 Expert Tricks for Smooth Cutting)

Now that we’ve covered the importance of tracking metrics, let’s dive into the three expert tricks to upgrade your MS261 chain for smoother cutting:

1. Choosing the Right Chain Type: Full Chisel vs. Semi-Chisel

This isn’t just about picking any chain; it’s about selecting the right chain for the job. The MS261 is a versatile saw, capable of handling a wide range of tasks. However, the stock chain is often a compromise, designed for general use. Upgrading to a specialized chain can dramatically improve cutting performance.

Full Chisel Chains: These chains feature aggressive, square-cornered cutters that slice through wood with exceptional speed. They are ideal for experienced users who prioritize speed and efficiency, particularly when working with clean, softwood logs. However, they dull more quickly when exposed to dirt or abrasive materials.
Semi-Chisel Chains: These chains have rounded cutters that are more forgiving and resistant to dulling in dirty conditions. They are a good choice for users who frequently cut wood that may contain dirt, bark, or other contaminants. They are also a good option for less experienced users who are still developing their sharpening skills.
Why It Matters: The shape of the cutter directly impacts the chain’s ability to slice through wood. Full chisel chains have a more aggressive cutting angle, which allows them to remove more material with each pass. However, this aggressive design also makes them more susceptible to damage from dirt and debris.
My Experience: I personally prefer full chisel chains for felling and bucking clean logs. The increased cutting speed is noticeable, and I can process more wood in less time. However, when I’m cutting firewood from salvaged logs or working in areas with a lot of dirt, I switch to a semi-chisel chain to avoid excessive dulling.
Actionable Insight: Consider the type of wood you’ll be cutting most often and the conditions in which you’ll be working. If you’re primarily cutting clean softwood, a full chisel chain is a great choice. If you’re cutting dirty wood or working in abrasive conditions, a semi-chisel chain may be a better option.
Measuring Success: Track your bucking time (Metric #1) with both chain types. You should see a noticeable difference in cutting speed with the full chisel chain, especially in clean wood. Also, monitor chain sharpness (Metric #5) to see how quickly each chain dulls under different conditions.

2. Switching to a Narrow Kerf Chain and Bar

This is where things get interesting. A “kerf” is the width of the cut made by the chainsaw. A narrow kerf chain and bar combination reduces the amount of wood the saw needs to remove, resulting in faster cutting speeds and reduced fuel consumption.

What is a Narrow Kerf Chain? A narrow kerf chain is designed to cut a narrower path through the wood compared to a standard chain. This is achieved by using thinner cutters and a narrower bar.
Benefits of a Narrow Kerf System:
- Increased Cutting Speed: Less wood to remove means faster cutting.
- Reduced Fuel Consumption: The saw works less hard, consuming less fuel.
- Less Vibration: A narrower cut reduces friction and vibration.
- Easier on the Saw: Reduced load on the engine prolongs the saw’s life.
My Experience: I was skeptical about narrow kerf chains at first, but after trying one, I was amazed by the difference. My MS261 felt lighter and more responsive, and I could cut through logs much faster. I also noticed a significant reduction in fuel consumption.
Actionable Insight: Consider upgrading to a narrow kerf chain and bar if you’re looking for a significant boost in cutting performance. Make sure to choose a chain and bar that are specifically designed for your MS261.
Measuring Success: Track your bucking time (Metric #1) and fuel consumption (Metric #4) before and after switching to a narrow kerf chain and bar. You should see a noticeable improvement in both metrics. Also, pay attention to the amount of vibration you feel while cutting. A narrow kerf system should reduce vibration, making the saw more comfortable to use.

3. Optimizing Chain Tension and Lubrication

This may seem basic, but it’s often overlooked. Proper chain tension and lubrication are crucial for smooth cutting and preventing damage to your chainsaw.

Chain Tension:
- Too Loose: The chain will sag and may derail from the bar.
- Too Tight: The chain will bind and may overheat, causing premature wear.
- Proper Tension: The chain should be snug against the bar but still able to be pulled around by hand.
Chain Lubrication:
- Importance: Lubrication reduces friction between the chain and the bar, preventing overheating and wear.
- Oil Type: Use a high-quality bar and chain oil specifically designed for chainsaws.
- Oil Flow: Ensure the oiler is functioning properly and delivering an adequate amount of oil to the chain.
My Experience: I’ve seen firsthand the damage that can result from improper chain tension and lubrication. I once had a chain break on me mid-cut because it was too loose and hadn’t been properly lubricated. It was a scary experience that taught me the importance of paying attention to these details.
Actionable Insight: Check your chain tension before each use and adjust as needed. Make sure your oiler is functioning properly and that you’re using a high-quality bar and chain oil. Regularly inspect your bar for wear and damage, and replace it as needed.
Measuring Success: Monitor your chain and bar wear. If you’re experiencing excessive wear, it could be a sign of improper tension or lubrication. Also, pay attention to the temperature of your bar. If it’s getting excessively hot, it could indicate insufficient lubrication. Also track equipment downtime (Metric #9) to see if proper maintenance reduces the overall downtime.
