Unleashing the Power of Your Stihl MS 170: 5 Pro Hacks for Smooth Cuts
The Stihl MS 170 is a fantastic little chainsaw, perfect for homeowners and those just getting started with wood processing. It’s lightweight, easy to handle, and surprisingly powerful for its size. However, like any tool, it performs best when properly maintained and used with the right techniques. The goal is to transform your experience from a frustrating chore to an efficient, almost meditative process.
1. The Razor’s Edge: Mastering Chain Sharpening
Why it Matters:
A sharp chain is the single most important factor in achieving smooth cuts. A dull chain doesn’t cut; it tears and grinds, leading to rough cuts, increased effort, and potential kickback. Think of it like trying to slice a tomato with a butter knife. Impossible, right? Same principle applies here.
My Personal Experience:
I remember one particularly grueling day trying to fell a small oak with a chain that had seen better days. I spent more time fighting the saw than actually cutting. The cuts were ragged, the saw was vibrating like crazy, and I was exhausted. That’s when I vowed to never let my chain get that dull again.
The Hack: A Step-by-Step Guide to Sharpening
There are several methods for sharpening a chainsaw chain, but I prefer using a file and guide. It gives you the most control and allows you to maintain the correct angles.
Tools You’ll Need:
- Chainsaw File: Choose the correct diameter file for your chain (typically 5/32″ or 4.0mm for the MS 170).
- File Guide: A file guide helps you maintain the correct filing angle and depth.
- Depth Gauge Tool: This tool is used to check and adjust the depth gauges (rakers).
- Vise: A small vise to hold the chainsaw bar securely.
- Gloves: Protect your hands!
Steps:
- Secure the Bar: Clamp the chainsaw bar securely in the vise.
- Identify the Cutting Angle: Most chains have a mark on the cutter that indicates the correct filing angle. If not, consult your chainsaw manual. Typically, it’s around 25-30 degrees.
- Position the File Guide: Place the file guide on the chain, aligning it with the cutting angle.
- File Each Cutter: Using smooth, consistent strokes, file each cutter from the inside out. Maintain the same angle and pressure for each cutter. I usually aim for 3-5 strokes per cutter.
- Sharpen Alternating Cutters: Sharpen every other cutter on one side of the chain, then flip the saw and sharpen the remaining cutters.
- Check Depth Gauges (Rakers): Use the depth gauge tool to check the height of the depth gauges (rakers). These should be slightly lower than the cutters. If they’re too high, the chain won’t cut effectively.
- File Depth Gauges (if necessary): If the depth gauges are too high, use a flat file to carefully lower them. Be conservative; you can always file them down more if needed.
Data-Backed Insight:
A study by the Forest Engineering Research Institute of Canada (FERIC) found that properly sharpened chains can increase cutting efficiency by up to 20% and reduce fuel consumption by 10%. That’s a significant difference!
Expert Quote:
“Sharpening your chain is like tuning your car,” says veteran logger, Jim Harrison. “It’s essential for peak performance and safety. Don’t skimp on it.”
Practical Tip:
Invest in a good quality file and file guide. They’ll make the sharpening process much easier and more accurate.
Call to Action:
Don’t wait until your chain is completely dull. Sharpen it regularly, even if it’s just a few strokes after each use. Your arms and your chainsaw will thank you.
2. The Bar is the Foundation: Maintenance for Smooth Operation
Why it Matters:
The chainsaw bar is the backbone of the cutting system. A damaged or poorly maintained bar can lead to uneven cuts, chain wear, and even accidents. Think of it as the wheels on your car. If they’re out of alignment, the ride will be bumpy and inefficient.
My Personal Experience:
I once neglected my chainsaw bar for far too long. It developed burrs and uneven wear, which caused the chain to wobble and bind. The cuts were terrible, and I ended up replacing the bar much sooner than I should have. Lesson learned!
The Hack: A Step-by-Step Guide to Bar Maintenance
Tools You’ll Need:
- Flat File: For removing burrs and smoothing the bar rails.
- Bar Rail Dresser: A specialized tool for ensuring the bar rails are square and even.
- Wire Brush: For cleaning debris from the bar groove and oil holes.
- Rags: For wiping down the bar.
Steps:
- Clean the Bar: Use a wire brush to remove any sawdust, pitch, or debris from the bar groove and oil holes. Clogged oil holes can lead to insufficient lubrication and premature bar wear.
- Inspect for Burrs: Carefully inspect the bar rails for any burrs or raised edges. These can snag the chain and cause rough cuts.
- Remove Burrs: Use a flat file to carefully remove any burrs from the bar rails. File in a smooth, even motion, following the contour of the bar.
- Dress the Bar Rails: If the bar rails are uneven or worn, use a bar rail dresser to square them up. This will ensure the chain runs smoothly and evenly.
- Check Bar Straightness: Place the bar on a flat surface and check for any bends or warps. A bent bar can cause uneven cuts and chain derailment. If the bar is bent, it may need to be replaced.
- Lubricate the Bar: Apply a small amount of chainsaw bar oil to the bar rails before installing the chain. This will help reduce friction and wear.
Data-Backed Insight:
Regular bar maintenance can extend the life of your chainsaw bar by up to 50%, according to a study by Oregon Products, a leading manufacturer of chainsaw bars and chains.
Expert Quote:
“A well-maintained bar is just as important as a sharp chain,” says arborist, Sarah Miller. “It’s the foundation of a smooth and efficient cutting system.”
Practical Tip:
Clean your chainsaw bar after each use. It only takes a few minutes and can significantly extend its lifespan.
Call to Action:
Take the time to inspect and maintain your chainsaw bar regularly. It’s an investment in the longevity and performance of your chainsaw.
3. The Tightrope Walker: Achieving Perfect Chain Tension
Why it Matters:
Proper chain tension is crucial for smooth cutting, safety, and chain longevity. Too loose, and the chain can derail, causing damage and potential injury. Too tight, and the chain can bind, overheat, and wear out prematurely. It’s a delicate balance.
My Personal Experience:
I once ran my chainsaw with the chain too loose. The chain derailed mid-cut, sending it flying. Luckily, no one was hurt, but it scared me half to death and damaged the chain. I learned my lesson the hard way.
The Hack: A Step-by-Step Guide to Adjusting Chain Tension
Tools You’ll Need:
- Scrench (Combination Wrench and Screwdriver): Usually included with your chainsaw.
- Gloves: Protect your hands!
Steps:
- Loosen the Bar Nuts: Use the scrench to loosen the bar nuts that hold the side cover in place. Don’t remove the nuts completely; just loosen them enough to allow the bar to move.
- Adjust the Tensioning Screw: Locate the chain tensioning screw. This is usually located on the side of the chainsaw, near the bar. Turn the screw clockwise to tighten the chain and counterclockwise to loosen it.
- Check the Tension: The chain should be snug against the bar but still able to be pulled around the bar by hand. A good rule of thumb is that you should be able to pull the chain away from the bar about 1/8″ (3mm) at the midpoint.
- Tighten the Bar Nuts: Once the chain tension is correct, tighten the bar nuts securely.
- Recheck the Tension: After tightening the bar nuts, recheck the chain tension. It may have changed slightly during the tightening process.
- Warm Up the Saw: Start the chainsaw and let it run for a few minutes. The chain will expand as it heats up, so you may need to readjust the tension after it warms up.
Data-Backed Insight:
A study by Stihl found that maintaining proper chain tension can extend chain life by up to 30%.
Expert Quote:
“Chain tension is something you should check every time you use your chainsaw,” says chainsaw repair technician, Mark Johnson. “It’s a simple adjustment that can make a big difference in performance and safety.”
Practical Tip:
Check the chain tension frequently, especially when using a new chain. New chains tend to stretch more than older chains.
Call to Action:
Make chain tension a regular part of your chainsaw maintenance routine. It’s a small adjustment that can prevent big problems.
4. The Art of the Cut: Mastering Cutting Techniques
Why it Matters:
Even with a sharp chain and a well-maintained bar, poor cutting technique can lead to rough cuts, kickback, and fatigue. The key is to let the saw do the work; don’t force it.
My Personal Experience:
I used to muscle my way through cuts, forcing the saw and putting unnecessary strain on my body. The cuts were rough, and I was always exhausted. Then I learned the importance of letting the saw do the work. It made a world of difference.
The Hack: Pro Cutting Techniques
- Use the Correct Part of the Chain: The bottom of the chain is designed for cutting. Avoid using the tip of the bar, as this can increase the risk of kickback.
- Maintain a Steady Pressure: Apply a steady, even pressure to the saw. Don’t push too hard or let the saw bounce around.
- Let the Saw Do the Work: Let the chain do the cutting. Don’t try to force the saw through the wood.
- Keep the Saw Level: Keep the saw level and avoid twisting or bending the bar.
- Use a Guide: When cutting logs, use a guide to ensure a straight, even cut.
- Be Aware of Kickback: Kickback is a sudden, forceful upward movement of the chainsaw bar. It can be caused by pinching the chain or by hitting a knot or other obstruction. Be aware of the risk of kickback and take precautions to avoid it.
Data-Backed Insight:
Proper cutting technique can reduce the risk of kickback by up to 50%, according to the Chainsaw Safety Foundation.
Expert Quote:
“Cutting technique is all about letting the saw do the work,” says logging instructor, Susan Davis. “Don’t fight the wood; let the saw guide you.”
Practical Tip:
Practice your cutting technique on scrap wood before tackling larger projects.
Call to Action:
Focus on developing good cutting habits. It will make your work easier, safer, and more efficient.
5. The Lifeblood of the Saw: Oil and Lubrication
Why it Matters:
Proper lubrication is essential for keeping your chainsaw running smoothly and preventing premature wear. The chain and bar need to be constantly lubricated to reduce friction and heat.
My Personal Experience:
I once ran my chainsaw without checking the oil level. The chain overheated and seized up, damaging the bar and chain. It was a costly mistake that I won’t make again.
The Hack: Oil and Lubrication Best Practices
- Use the Right Oil: Use a high-quality chainsaw bar and chain oil. Avoid using motor oil or other substitutes, as they are not designed for the high speeds and temperatures of a chainsaw chain.
- Check the Oil Level Regularly: Check the oil level before each use and refill as needed.
- Adjust the Oil Flow: Most chainsaws have an adjustable oil flow. Adjust the flow so that the chain is adequately lubricated without excessive oil consumption.
