Stihl MS 180 vs 170: Best Chainsaw for Small Logs (5 Pro Tips)

Let’s dive into the world of small log chainsawing, where efficiency and precision are key. I’ve spent years in the wood processing industry, from felling trees to prepping firewood, and I’ve learned that choosing the right tool and understanding its capabilities can make all the difference. I’ll also introduce some key project metrics, crucial for optimizing any wood processing endeavor.

1. Understanding the Core Differences: MS 170 vs MS 180

Before we get into the tips, it’s crucial to understand the fundamental differences between these two Stihl models. Both are designed for light-duty tasks, but subtle variations in their specifications can impact performance.

Engine Size and Power: The MS 180 generally boasts a slightly more powerful engine than the MS 170. While the difference might seem negligible on paper, it can translate to a noticeable improvement in cutting speed and ability to handle slightly thicker logs.
Weight: The weight difference between the two is minimal, often within a few ounces. However, for extended use, even small weight differences can contribute to fatigue.
Price: The MS 170 is typically the more budget-friendly option.
Bar Length: Both models are commonly available with bar lengths ranging from 14 to 16 inches, suitable for small logs.

2. Pro Tip #1: Assess Your Log Diameter – Matching Saw to Task

The most crucial factor in choosing between the MS 170 and MS 180 is the typical diameter of the logs you’ll be cutting.

Logs under 6 inches: For consistently cutting logs under 6 inches in diameter, the MS 170 is often sufficient. Its lighter weight and lower price point make it a practical choice for smaller tasks.
Logs between 6 and 10 inches: If you regularly encounter logs in this size range, the MS 180’s extra power will be beneficial. It will cut through these logs more quickly and efficiently, reducing strain on both the saw and yourself.
Logs over 10 inches: While both saws can handle logs over 10 inches, it’s not their ideal operating range. You’ll likely experience slower cutting speeds and increased risk of bogging down. For larger logs, consider a more powerful chainsaw.

Example: I once worked on a project clearing fallen branches after a storm. The majority of the branches were under 5 inches in diameter. The MS 170 proved to be the perfect tool – lightweight, easy to maneuver, and more than capable of handling the task. However, when we encountered a few larger limbs (around 8 inches), the MS 180 made significantly quicker work of them.

Project Metric: Cutting Time per Log

Definition: The average time taken to cut through one log of a specific diameter.
Importance: This metric helps assess the efficiency of the chainsaw and identify potential bottlenecks in your workflow.
Interpretation: A lower cutting time indicates better performance.
Relationship to other metrics: Directly related to fuel consumption, operator fatigue, and overall project completion time.
Tracking: Use a stopwatch to record the time taken to cut through a sample of logs. Calculate the average cutting time for each log diameter.
Data-Backed Insight: In a recent firewood project, I tracked the cutting time for logs of varying diameters using both the MS 170 and MS 180. The MS 180 consistently showed a 15-20% reduction in cutting time for logs between 6 and 8 inches compared to the MS 170.

3. Pro Tip #2: Mastering Chain Maintenance – Sharpness is Key

Regardless of which saw you choose, maintaining a sharp chain is paramount for efficient cutting and safety. A dull chain will not only slow you down but also increase the risk of kickback.

Regular Sharpening: Sharpen the chain regularly, ideally after every few tanks of fuel, or whenever you notice a decrease in cutting performance.
Proper Filing Technique: Use a chainsaw file and follow the correct filing angles to maintain the chain’s cutting edges. There are plenty of excellent online tutorials available.
Chain Tension: Ensure the chain is properly tensioned. A loose chain can derail, while an overtightened chain can cause excessive wear on the bar and sprocket.
Chain Selection: Using the correct chain type for your saw and the type of wood you’re cutting will also improve performance.

Personal Story: I once spent an entire afternoon struggling to cut through a pile of oak logs with my MS 170. I was convinced the saw was underpowered. However, after finally sharpening the chain, it felt like I was using a completely different machine. The difference was night and day.

Project Metric: Chain Sharpening Frequency

Definition: The number of times the chainsaw chain needs to be sharpened per unit of wood processed (e.g., per cord of firewood).
Importance: Indicates the abrasiveness of the wood being cut and the effectiveness of the chain sharpening technique.
Interpretation: A higher sharpening frequency suggests more abrasive wood or a less effective sharpening method.
Relationship to other metrics: Related to chain lifespan, cutting time, and fuel consumption.
Tracking: Keep a log of when you sharpen the chain and the amount of wood processed since the last sharpening.
Data-Backed Insight: By tracking chain sharpening frequency, I discovered that cutting seasoned oak required sharpening the chain twice as often as cutting seasoned pine. This led me to adjust my sharpening technique and consider using a different chain type for oak.

4. Pro Tip #3: Fuel Efficiency and Oil Consumption – Minimizing Running Costs

Running a chainsaw involves ongoing expenses, primarily fuel and bar oil. Optimizing fuel efficiency and oil consumption can significantly reduce your operating costs.

Fuel Mix Ratio: Always use the correct fuel-to-oil mix ratio as specified by Stihl (usually 50:1 for newer models). Using the wrong ratio can damage the engine.
Bar Oil Quality: Use high-quality bar oil to lubricate the chain and bar. This will reduce friction, extend the life of the bar and chain, and improve cutting performance.
Avoid Idling: Minimize idling time to conserve fuel.
Clean Air Filter: A clean air filter ensures proper airflow to the engine, improving fuel efficiency.

Unique Insight: I’ve found that using premium bar oil, even though it costs slightly more, significantly reduces chain wear and extends the life of the bar. This more than offsets the higher cost of the oil.

Project Metric: Fuel Consumption per Hour

Definition: The amount of fuel consumed by the chainsaw per hour of operation.
Importance: Indicates the efficiency of the engine and helps estimate fuel costs.
Interpretation: Lower fuel consumption is desirable.
Relationship to other metrics: Related to cutting time, wood volume processed, and maintenance costs.
Tracking: Measure the amount of fuel used during a specific period of operation and divide by the number of hours worked.
Data-Backed Insight: I compared the fuel consumption of the MS 170 and MS 180 while cutting similar-sized logs. The MS 180, despite its slightly more powerful engine, consumed only marginally more fuel per hour, likely due to its ability to cut through the logs more quickly.

5. Pro Tip #4: Ergonomics and User Comfort – Preventing Fatigue and Injury

Using a chainsaw, even a lightweight one, can be physically demanding. Prioritizing ergonomics and user comfort is essential for preventing fatigue and reducing the risk of injury.

Proper Posture: Maintain a stable stance and avoid overreaching.
Grip: Use a firm but relaxed grip. Avoid gripping the saw too tightly, as this can lead to fatigue.
Breaks: Take frequent breaks to rest and stretch.
Protective Gear: Always wear appropriate personal protective equipment (PPE), including a helmet, eye protection, hearing protection, gloves, and chaps.

Experience: I learned the hard way about the importance of ergonomics. After spending a full day cutting firewood without taking adequate breaks, I developed severe back pain that lasted for days. Now, I make sure to take short breaks every hour to stretch and rest.

Project Metric: Operator Fatigue Index

Definition: A subjective measure of operator fatigue level on a scale of 1 to 10, assessed at regular intervals during operation.
Importance: Indicates the physical demands of the task and helps identify potential risks of fatigue-related injuries.
Interpretation: Lower fatigue index is desirable.
Relationship to other metrics: Related to cutting time, wood volume processed, and break frequency.
Tracking: Ask the operator to rate their fatigue level every hour on a scale of 1 to 10 (1 = not fatigued, 10 = extremely fatigued).
Data-Backed Insight: By tracking the operator fatigue index, I realized that tasks involving repetitive cutting of small logs resulted in higher fatigue levels compared to tasks involving occasional cutting of larger logs. This led me to implement more frequent breaks and rotate tasks to reduce the risk of fatigue-related injuries.

6. Pro Tip #5: Long-Term Maintenance and Storage – Extending the Life of Your Saw

Proper maintenance and storage are crucial for extending the life of your chainsaw and ensuring its reliable performance.
