Stihl Chain MS170 Guide for Firewood Cutting (5 Pro Tips)

Stihl MS170 Guide for Firewood Cutting: 5 Pro Tips

The Stihl MS170 is a popular choice for homeowners and occasional users due to its lightweight design, ease of use, and reasonable price point. It’s a great tool for smaller jobs, but like any tool, it’s only as effective as the person wielding it. Through years of trial and error, I’ve honed my techniques to maximize its potential for firewood cutting. These five pro tips will help you cut faster, safer, and more efficiently.

1. Instead of cutting straight through, you use the tip of the chainsaw to bore into the wood, creating a controlled cut that prevents pinching and kickback.

• Why it works: The bore cut allows you to relieve internal tension in the wood before completing the cut, minimizing the risk of the bar getting pinched. This is especially useful when dealing with logs that are under pressure or resting on uneven surfaces.

• How to do it:

  1. Set Up: Position yourself firmly and ensure you have a clear escape path.
  2. Initial Cut: Make a small notch on the top of the log, guiding the saw with the bottom of the bar.
  3. Bore In: Carefully plunge the tip of the bar into the wood at a slight angle. Let the saw do the work; don’t force it.
  4. Pivot and Cut: Once the bar is deep enough, pivot the saw to cut through the wood, leaving a hinge.
  5. Final Cut: Finish the cut from the opposite side, meeting the bore cut and allowing the log to separate cleanly.

• Safety First: Always be aware of the position of the saw and the potential for kickback. Use a low-kickback chain and maintain a firm grip.
• My Experience: I once tackled a pile of oak logs that were notorious for pinching. By using the bore cut, I was able to cut through them with ease, saving time and frustration. This technique transformed a tedious job into a manageable task.

2. Sharpening Your Chain: The Key to Efficiency

A dull chain is a dangerous chain. It requires more force to cut, increases the risk of kickback, and puts unnecessary strain on your chainsaw. Keeping your chain sharp is crucial for both safety and efficiency.

• Why it matters: A sharp chain cuts smoothly and effortlessly, reducing the physical strain on you and the wear and tear on your chainsaw. It also minimizes the risk of accidents caused by the saw jumping or binding.

• How to sharpen:

  1. Gather Your Tools: You’ll need a chainsaw file, a file guide, and a depth gauge tool.
  2. Secure the Saw: Clamp the chainsaw in a vise or use a bar clamp to hold it securely.
  3. File the Cutters: Use the file guide to maintain the correct angle and depth. File each cutter with smooth, even strokes, working in one direction.
  4. Check the Depth Gauges: Use the depth gauge tool to ensure the depth gauges are set correctly. File them down if necessary.
  5. Test the Chain: After sharpening, test the chain on a piece of wood. It should cut smoothly and produce even chips.

• Pro Tip: I use a round file that matches the pitch of my chain. Stihl provides a chart that makes it easy to determine the correct file size.
• Frequency: How often should you sharpen? As a rule of thumb, sharpen your chain after every tank of gas or whenever you notice a decrease in cutting performance.
• Statistics: According to a study by the US Forest Service, a sharp chainsaw can increase productivity by up to 20% and reduce the risk of accidents by 15%.

3. Limbing Like a Pro: Staying Safe and Efficient

Limbing, the process of removing branches from a felled tree, can be one of the most dangerous aspects of firewood preparation. It requires careful planning, precise cuts, and a constant awareness of your surroundings.

• Why it’s critical: Limbing is often performed on uneven terrain, with branches under tension. Improper techniques can lead to kickback, pinching, and even falling branches.

• Best Practices:

  1. Plan Your Approach: Before you start, assess the situation. Identify any branches that are under tension and plan your cuts accordingly.
  2. Work from the Base Up: Start at the base of the tree and work your way up, removing branches as you go.
  3. Use the Bore Cut: The bore cut is especially useful for limbing, as it allows you to relieve tension before completing the cut.
  4. Maintain a Safe Distance: Keep your body out of the path of the saw and any falling branches.
  5. Clear the Area: As you work, clear away any branches and debris to create a safe working area.

• Personal Story: I once witnessed a logger who was rushing through the limbing process get hit by a falling branch. He was lucky to escape with only minor injuries. This incident reinforced the importance of taking your time and following proper safety procedures.

• Expert Quote: “Limbing is where most chainsaw accidents happen,” says Tim Ard, a certified arborist. “Take your time, plan your cuts, and always be aware of your surroundings.”

4. Bucking for Efficiency: Maximizing Your Output

Bucking is the process of cutting logs into shorter lengths for splitting and stacking. The goal is to maximize your output while minimizing waste and effort.

• Key Considerations:

  1. Log Length: Determine the ideal log length for your stove or fireplace. I typically cut my logs to 16 inches, but this may vary depending on your needs.
  2. Log Support: Use a sawbuck or log supports to keep the logs off the ground. This will make cutting easier and safer.
  3. Cutting Technique: Use a combination of the bore cut and standard cutting techniques to minimize pinching and kickback.
  4. Waste Reduction: Position your cuts to minimize waste and maximize the amount of usable wood.

• Workflow Optimization: I’ve found that setting up a dedicated bucking station with a sawbuck and a measuring stick significantly increases my efficiency. This allows me to quickly and accurately cut logs to the desired length.
