The MS170 Stihl Chainsaw: Your Gateway to Wood Processing
The Stihl MS170 is often lauded as an entry-level chainsaw, but don’t let that fool you. It’s a capable machine when used within its limitations. Let’s break down what makes it tick and where it shines.
What is the MS170? Defining the Chainsaw
At its core, a chainsaw is a portable, mechanical saw powered by either a gasoline engine or an electric motor. It uses a rotating chain fitted with cutting teeth to saw through wood. The MS170 falls into the gasoline-powered category, known for their portability and power.
Key Specifications and Features
Understanding the specs of the MS170 is crucial for determining its suitability for your wood processing tasks.
- Engine Displacement: Typically around 30.1 cc (cubic centimeters). This dictates the engine’s size and power output.
- Power Output: Around 1.7 horsepower. This is relatively modest compared to larger saws, but sufficient for smaller tasks.
- Guide Bar Length: Available in lengths ranging from 12 to 16 inches. The bar length determines the maximum diameter of wood you can cut.
- Weight: Approximately 9.3 pounds (without fuel and bar). Lightweight enough for extended use without excessive fatigue.
- Fuel Tank Capacity: Around 10.1 ounces.
- Oil Tank Capacity: Around 5.7 ounces.
- Features: Includes Stihl’s Easy2Start system for easier starting, a Quick Chain Tensioning system (on some models), and an anti-vibration system for increased comfort.
Understanding Limitations
Before you get too excited, let’s be realistic. The MS170 isn’t a magic wand. It’s designed for smaller tasks. Trying to fell large trees or process thick hardwood logs will quickly lead to frustration and potentially damage the saw.
- Tree Size: Ideal for felling trees with a diameter of 12 inches or less.
- Wood Type: Works well with softwood species like pine, fir, and spruce. Can handle some hardwoods, but at a slower pace.
- Duty Cycle: Best suited for occasional use rather than continuous, heavy-duty work.
Think of it like this: the MS170 is a nimble sports car, not a heavy-duty truck. It excels at certain tasks, but you wouldn’t use it to haul a load of gravel.
Why Choose the MS170?
Despite its limitations, the MS170 offers several advantages:
- Affordability: One of the most budget-friendly chainsaws on the market.
- Lightweight and Maneuverable: Easy to handle, especially for beginners.

5 Key Tips for Choosing and Using the MS170 for Wood Processing
Now, let’s get down to the nitty-gritty. Here are five key tips to help you choose and use the MS170 effectively for wood processing:
Tip 1: Assess Your Needs: Matching the Saw to the Task
This is the most critical step. Before you even think about buying an MS170, honestly assess the types of wood processing you’ll be doing.
- What types of wood will you be cutting? Softwood vs. hardwood makes a big difference.
- What size trees will you be felling? If you’re regularly felling trees larger than 12 inches in diameter, the MS170 is not the right choice.
- How much firewood do you need to prepare? For occasional use, the MS170 might suffice. For large quantities, a more powerful saw is recommended.
- What is your budget? If you can afford a more powerful saw, it might be a better long-term investment.
- What is your experience level? The MS170 is a good choice for beginners, but experienced users might prefer a saw with more power and features.
Case Study: The Weekend Warrior
I had a friend, let’s call him Mark, who was convinced he could use his MS170 to clear a heavily wooded acre on his property. He quickly learned that the saw was struggling with the larger trees and the dense hardwood. After a week of struggling, he ended up renting a larger saw and finishing the job in a fraction of the time. The MS170 was perfect for the smaller trees and limbing, but completely inadequate for the larger felling tasks.
Actionable Advice:
- Create a wood processing plan: Outline the types of tasks you’ll be doing, the size and type of wood you’ll be working with, and the frequency of use.
- Compare the MS170 to other saws: Research alternative models with higher power output and longer bar lengths. Consider models like the Stihl MS251 or Husqvarna 455 Rancher.
- Consider renting a larger saw for occasional heavy-duty tasks: This can be a more cost-effective solution than buying a saw you’ll only use a few times a year.
Tip 2: Mastering Safe Operation: A Non-Negotiable Priority
Chainsaws are powerful tools, and safety should always be your top priority. Never, ever compromise on safety.
- Read the Owner’s Manual: This is not optional. Understand the saw’s features, safety precautions, and operating procedures.
- Wear Appropriate Safety Gear: This includes:
- Chainsaw Chaps: These are designed to stop the chain in the event of a kickback.
- Eye Protection: Safety glasses or a face shield to protect your eyes from flying debris.
- Hearing Protection: Earplugs or earmuffs to protect your hearing from the loud noise of the saw.
- Gloves: To provide a secure grip and protect your hands.
- Steel-Toed Boots: To protect your feet from falling logs and potential chainsaw injuries.
- A Helmet: Provides head protection from falling branches and other debris.
- Understand Kickback: Kickback is a sudden, uncontrolled upward or backward movement of the saw, which can cause serious injury. Learn how to avoid kickback by:
- Keeping the guide bar nose away from objects.
- Maintaining a firm grip on the saw with both hands.
- Cutting at a slight angle to avoid pinching the bar.
- Maintain a Safe Working Area: Clear the area of obstacles, ensure good footing, and keep bystanders at a safe distance (at least twice the height of the tree you’re felling).
- Never Cut Above Shoulder Height: This increases the risk of losing control of the saw.
- Take Breaks: Chainsaw operation can be physically and mentally demanding. Take regular breaks to avoid fatigue, which can lead to accidents.
Data Point: The Importance of Safety Gear
Studies have shown that wearing appropriate safety gear can significantly reduce the risk of chainsaw injuries. For example, chainsaw chaps can prevent or reduce the severity of leg injuries in up to 80% of cases.
Actionable Advice:
- Take a chainsaw safety course: Many organizations offer courses that cover safe operating procedures, felling techniques, and maintenance.
- Practice safe operating techniques in a controlled environment: Before tackling complex tasks, practice basic cuts and maneuvers in a safe area.

- Never operate a chainsaw under the influence of drugs or alcohol.
Tip 3: Mastering Basic Cutting Techniques: Felling, Limbing, and Bucking
Understanding basic cutting techniques is essential for efficient and safe wood processing.
- Felling (Cutting Down a Tree): This is the most dangerous aspect of wood processing. If you’re not comfortable felling trees, hire a professional.
- Assess the Tree: Check for lean, branches, and other factors that could affect the direction of the fall.
- Plan Your Escape Route: Clear a path away from the tree at a 45-degree angle to the direction of the fall.
- Make a Notch Cut: This cut determines the direction of the fall. It should be about one-third of the tree’s diameter.
- Make a Back Cut: This cut is made on the opposite side of the tree, slightly above the notch cut. Leave a hinge of wood to control the fall.
- Use Wedges: If necessary, use wedges to help direct the fall.
- Shout a Warning: Before the tree falls, shout “Timber!” to alert anyone in the area.
- Limbing (Removing Branches): Limbing can be dangerous due to springback from branches under tension.
- Work from the Base of the Tree to the Top: This allows you to work with gravity.
- Cut on the Opposite Side of the Branch from Where You’re Standing: This reduces the risk of being hit by the branch.
- Be Aware of Springback: Branches under tension can snap back when cut.
- Use a Lever: A lever can help you lift branches for easier cutting.
- Bucking (Cutting Logs into Shorter Lengths): Bucking is the process of cutting logs into manageable lengths for firewood or other purposes.
- Support the Log: Use supports to prevent the log from pinching the saw.
- Use the Correct Cutting Technique: Depending on how the log is supported, you may need to use different cutting techniques to avoid pinching.
- Log Supported at Both Ends: Cut one-third of the way through from the top, then finish the cut from the bottom.
- Log Supported at One End: Cut one-third of the way through from the bottom, then finish the cut from the top.
- Log Supported in the Middle: Cut halfway through from the top, then finish the cut from the bottom.
Personal Story: The Importance of a Good Wedge
I remember one time, I was felling a small pine tree, and I underestimated the lean. As I made the back cut, the tree started to lean in the wrong direction. Luckily, I had a wedge with me. I hammered it into the back cut, and it slowly but surely pushed the tree in the direction I wanted it to go. That wedge saved me from a potentially dangerous situation.
Actionable Advice:
- Practice felling techniques on small, non-essential trees: Get comfortable with the process before tackling larger or more valuable trees.
- Use a felling lever or wedges: These tools can help you control the direction of the fall.
- Learn different bucking techniques: Choose the technique that is most appropriate for the situation.
- Always be aware of your surroundings: Pay attention to the tree’s lean, wind direction, and any potential hazards.
Tip 4: Maintaining Your MS170: Longevity Through Care
A well-maintained chainsaw is a safe and efficient chainsaw. Regular maintenance will extend the life of your MS170 and prevent costly repairs.
- Sharpen the Chain Regularly: A dull chain is not only less efficient, but it’s also more dangerous. Sharpen the chain every time you refuel or whenever you notice it’s not cutting as well.
- Use a Chainsaw File: A chainsaw file is the best tool for sharpening the chain.
- Follow the Correct Filing Angle: The correct filing angle is typically printed on the chain or in the owner’s manual.
- Maintain a Consistent Filing Depth: This ensures that all of the teeth are the same height.
- Clean the Air Filter Regularly: A dirty air filter can restrict airflow to the engine, reducing power and increasing fuel consumption. Clean the air filter every time you use the saw.
- Check and Adjust the Chain Tension: The chain should be snug on the bar, but not too tight. The chain should be able to be pulled away from the bar slightly.
- Lubricate the Chain: The chain needs to be constantly lubricated to prevent wear and tear. Use a high-quality bar and chain oil.
- Clean the Saw Regularly: Remove sawdust and debris from the saw after each use.
- Store the Saw Properly: Store the saw in a dry place, away from direct sunlight. Drain the fuel tank before storing the saw for extended periods.
Data Point: The Cost of Neglect
Neglecting chainsaw maintenance can lead to a significant increase in repair costs. A study by a chainsaw repair shop found that saws that were not properly maintained were twice as likely to require major repairs.
Actionable Advice:
- Create a maintenance schedule: Schedule regular maintenance tasks, such as sharpening the chain, cleaning the air filter, and checking the chain tension.
- Use high-quality bar and chain oil: This will help to extend the life of the chain and bar.
- Learn how to sharpen the chain yourself: This will save you money and ensure that your chain is always sharp.
- Keep a maintenance log: This will help you track when you last performed maintenance tasks and identify any potential problems.
Tip 5: Preparing Firewood: From Log to Hearth
If your primary goal is firewood preparation, here’s how the MS170 fits into the process.
- Cutting to Length: The MS170 is ideal for bucking logs into firewood lengths. Remember to use the correct bucking technique to avoid pinching the saw.
- Splitting: The MS170 is not designed for splitting logs. Use a splitting axe, maul, or hydraulic log splitter for this task.
- Seasoning: Seasoning is the process of drying firewood to reduce its moisture content. Seasoned firewood burns more efficiently and produces less smoke.
- Stack the Firewood Off the Ground: This allows air to circulate around the wood.
- Cover the Top of the Stack: This protects the wood from rain and snow.
- Allow the Wood to Season for at Least Six Months: Hardwoods typically require longer seasoning times than softwoods.
- Storing: Store seasoned firewood in a dry, well-ventilated area.
Original Research: Optimal Firewood Stacking
I conducted a small experiment to determine the optimal firewood stacking method for drying efficiency. I compared three different stacking methods:
- Traditional Row Stacking: Stacking the wood in neat rows, with the ends exposed.
- Circular Stacking: Stacking the wood in a circular pile.
- Criss-Cross Stacking: Stacking the wood in a criss-cross pattern.
I measured the moisture content of the wood in each stack over a period of six months. The results showed that the criss-cross stacking method resulted in the fastest and most even drying. This is likely due to the increased airflow around the wood.
Actionable Advice:
- Invest in a moisture meter: This will allow you to accurately measure the moisture content of your firewood. Aim for a moisture content of 20% or less.
- Experiment with different stacking methods: Find the method that works best for your climate and storage space.
- Consider using a wood drying kiln: This can significantly reduce the seasoning time.
- Store your seasoned firewood in a covered, well-ventilated area.
