MS170 Chainsaw Tips (5 Pro Woodcutting Hacks For Cabin Logs)

MS170 Chainsaw Tips: 5 Pro Woodcutting Hacks for Cabin Logs

Let’s dive straight in! You want to use your MS170 chainsaw like a pro for cabin logs. Forget the fluff; I’m giving you the quick and dirty secrets I’ve learned over years of wrestling timber. These are the hacks that will save you time, energy, and maybe even a trip to the emergency room. Let’s get those logs prepped!

The State of the Wood Game: Why These Hacks Matter

Before we get sawing, let’s look at the bigger picture. The global firewood market is booming, projected to reach billions in the coming years, and a significant chunk of that is driven by the demand for cabin construction and wood heating. But here’s the rub: efficiency and safety are paramount. According to recent data, improper chainsaw use accounts for a shocking number of injuries annually. My hacks aren’t just about speed; they’re about working smarter, not harder, and going home safe.

Hack #1: Chainsaw Sharpening – Razor Sharp is Life or Death

The Problem: A dull chain makes you work harder, increases the risk of kickback, and produces sawdust instead of chips. It’s a recipe for disaster.

My Story: I remember one time, early in my career, I was felling a decent-sized oak with a chain that was just dull enough. I figured, “Eh, I’ll get through it.” Big mistake. The saw pinched, kicked back, and nearly took out my knee. That’s when I learned the hard way: a sharp chain is non-negotiable.

The Solution: Sharpen your chain before you start, and then every time you refuel. Yes, every time.

Step-by-Step:

Secure the Saw: Use a vise to hold the chainsaw bar firmly.
Identify the Correct File Size: Check your chainsaw manual. The MS170 typically uses a 5/32″ (4.0mm) round file.
Use a File Guide: A file guide (like the Stihl 2-in-1 Easy File) is your best friend. It ensures consistent angle and depth.
Sharpen Each Cutter: File each tooth at the correct angle (usually marked on the file guide) with smooth, even strokes. Aim for 3-5 strokes per cutter.
Check Depth Gauges: These small “rakers” in front of each cutter control the depth of cut. Use a flat file and depth gauge tool to maintain the correct height (usually around 0.025″).
Clean and Oil: After sharpening, clean the chain and apply bar oil.

Data Point: Studies show that a properly sharpened chain can increase cutting efficiency by up to 30%.

Unique Insight: Don’t just sharpen the cutters; pay attention to the depth gauges. Overly aggressive depth gauges can cause excessive vibration and kickback.

Troubleshooting:

Chain pulls to one side: Cutters on one side are duller than the other.
Excessive vibration: Depth gauges are too high.
Chain won’t cut: Cutters are too short or depth gauges are too low.

Cost: A file guide costs around $20-$40. Files are cheap (a few dollars each). The Stihl 2-in-1 Easy File is a worthwhile investment.

Hack #2: The Bore Cut – Unlock the Log Like a Safe Cracker

The Problem: Felling larger trees or bucking logs with internal tension can lead to pinching, binding, and dangerous situations.

My Story: I was once bucking a massive piece of oak that had been down for a while. I made the mistake of just cutting straight through. The log pinched the bar so hard, I nearly bent it in half trying to pry it out. That’s when I learned the power of the bore cut.

The Solution: The bore cut allows you to relieve tension within the log before making the final cut.

Step-by-Step:

Assess the Log: Look for signs of tension – bending, cracking, or leaning.
Make an Open Face Cut: Cut a small notch (the “face”) on the side of the log you want it to fall towards (if felling) or on the side opposite the tension (if bucking).
Plunge Cut (Bore Cut): Carefully plunge the tip of the chainsaw bar into the log, behind the face cut. Use the bottom of the bar to pull the saw into the wood. Be extremely careful of kickback!
Create a Hinge: Once the bar is fully inserted, pivot the saw to create a “hinge” of uncut wood. This hinge controls the direction of the fall.
Make the Back Cut: Cut through the remaining wood from the opposite side, leaving a small amount of hinge wood.
Watch and Clear: As the log begins to fall or separate, step back and clear the area.

Diagram (Conceptual):

       Top of Log
       ---------
      /        \
     /  Face    \
    /    Cut     \
   /_____________\
  |             |
  |  Bore Cut   |
  |_____________|
       Hinge
       Back Cut

Data Point: Proper bore cutting techniques can reduce pinching incidents by up to 50%.

Unique Insight: The size of the hinge is critical. Too small, and the log can fall unpredictably. Too large, and it won’t fall at all. Practice makes perfect.

Troubleshooting:

Saw gets pinched: Stop immediately! Use wedges to relieve the pressure.
Log falls in the wrong direction: Hinge was too small or improperly positioned.

Cost: Wedges cost around $10-$20 each. A good felling lever can cost $50-$100.

Hack #3: The Power of Wedges – Your Mechanical Advantage

The Problem: Large logs can bind your saw, making felling or bucking difficult and dangerous.

My Story: I was once trying to fell a leaning pine tree without using wedges. The tree started to pinch the saw, and I was stuck. I had to call in a buddy with a second saw to free me. Now, I never leave home without a few wedges.

The Solution: Wedges provide mechanical advantage, preventing pinching and controlling the direction of the fall.

Step-by-Step:

Make Your Cut: Start your felling or bucking cut.
Insert Wedges: As the cut deepens, insert one or more wedges into the cut behind the saw.
Hammer the Wedges: Use a hammer or axe to drive the wedges further into the cut. This will force the log open, preventing pinching and helping to direct the fall.
Continue Cutting: Continue your cut, driving the wedges as needed.

Data Point: Using wedges can increase the success rate of felling trees in the desired direction by up to 20%.

Unique Insight: Use plastic or aluminum wedges, not steel. Steel wedges can damage your chain if you accidentally hit them.

Troubleshooting:

Wedges won’t stay in place: The cut is too narrow. Widen the cut slightly.
Wedges are ineffective: The log is too heavy or the wedges are too small. Use larger wedges or multiple wedges.

Cost: Wedges cost around $10-$20 each.

Hack #4: Leverage and Limb Removal – The Art of the Delimb

The Problem: Removing limbs efficiently and safely can be a real challenge, especially on large trees.

My Story: I used to just hack away at limbs, one at a time, often getting my saw pinched or having limbs fall on me. Then I learned to use leverage and proper cutting techniques. Now, I can delimb a tree in a fraction of the time, with far less effort.

The Solution: Use leverage to your advantage and employ specific cutting techniques to avoid pinching.

Step-by-Step:

Assess the Limb: Look for tension and the direction of the bend.
Relief Cut (Undercut): If the limb is under tension (bent downwards), make a small undercut on the bottom of the limb, about halfway through.
Top Cut: Finish the cut from the top, slightly further out than the undercut. This allows the limb to break cleanly, without pinching.
Compression Cut (Overcut): If the limb is under compression (bent upwards), make a small overcut on the top of the limb.
Bottom Cut: Finish the cut from the bottom.
Use Leverage: If the limb is too heavy to cut cleanly, leave a small “hinge” of wood. Then, use a branch hook or your foot to break the limb off at the hinge.

Data Point: Proper delimbing techniques can reduce chainsaw pinching incidents by up to 40%.

Unique Insight: Always stand to the side of the limb you are cutting, not directly underneath it. Limbs can spring back or fall unexpectedly.

Troubleshooting:

Saw gets pinched: Use wedges or a felling lever to relieve the pressure.
Limb falls unexpectedly: Be aware of the lean and tension of the limb.

Cost: A branch hook costs around $20-$40.

Hack #5: Chainsaw Maintenance – Keep Your Saw Singing

The Problem: Neglecting chainsaw maintenance leads to poor performance, increased risk of failure, and a shorter lifespan for your saw.

My Story: I used to think that chainsaw maintenance was a waste of time. I’d just run my saw until it broke down. Then I realized that I was spending more time and money fixing my saw than I would have spent on regular maintenance.

The Solution: Regular maintenance is essential for keeping your chainsaw running smoothly and safely.

Step-by-Step:

Daily Cleaning: After each use, clean the saw thoroughly. Remove sawdust and debris from the bar, chain, and engine.
Check Bar and Chain: Inspect the bar for wear and damage. Check the chain for sharpness and tension.
Air Filter: Clean or replace the air filter regularly. A clogged air filter reduces engine power and increases fuel consumption.
Spark Plug: Check the spark plug for fouling. Replace it if necessary.
Fuel and Oil: Use fresh, high-quality fuel and bar oil.
Sharpening: Sharpen the chain regularly, as described in Hack #1.
Professional Service: Take your chainsaw to a qualified technician for a professional service at least once a year.

Data Point: Regular chainsaw maintenance can extend the lifespan of your saw by up to 50%.

Unique Insight: Use a dedicated chainsaw cleaner to remove stubborn pitch and sap.

Troubleshooting:

Saw won’t start: Check the fuel, spark plug, and air filter.
Saw runs poorly: Check the air filter, spark plug, and carburetor.
Chain smokes excessively: The bar oiler is not working properly.

Cost: A chainsaw maintenance kit costs around $30-$50. Professional service costs vary depending on the complexity of the work.

Wood Species Know-How: Fuel for Thought

Understanding wood species is key to efficient cabin log preparation and firewood selection. Different woods have different densities, drying times, and heating values.

Hardwoods (Oak, Maple, Ash): Denser, burn longer, produce more heat, but take longer to season (dry).
Softwoods (Pine, Fir, Spruce): Less dense, burn faster, produce less heat, but season more quickly.

Data Point: Oak, a popular choice for firewood, can take up to two years to season properly. Pine, on the other hand, may be ready in as little as six months.

Unique Insight: The ideal moisture content for firewood is below 20%. Use a moisture meter to check the moisture content of your wood before burning it.

Seasoning: The Secret Sauce of Firewood

Seasoning is the process of drying wood to reduce its moisture content. This makes it easier to light, burn hotter, and produce less smoke.

Step-by-Step:

Split the Wood: Split logs into smaller pieces to increase surface area for drying.
Stack the Wood: Stack the wood in a single row, off the ground, with good air circulation.
Cover the Top: Cover the top of the stack to protect it from rain and snow, but leave the sides open for ventilation.
Wait Patiently: Allow the wood to season for at least six months, or preferably a year or more.

Data Point: Properly seasoned firewood can produce up to 50% more heat than green wood.

Unique Insight: The best time to cut and split firewood is in the late winter or early spring, before the sap starts to rise.

Budgeting for Wood Processing: Counting the Cost

Wood processing can be expensive, especially if you’re starting from scratch. Here’s a breakdown of the typical costs:

Chainsaw: $200-$500 (for a decent homeowner model)
Safety Gear: $100-$200 (helmet, chaps, gloves, ear protection)
Tools: $50-$100 (wedges, felling lever, axe)
Maintenance: $50-$100 per year (oil, filters, spark plugs, sharpening)
Fuel: Variable, depending on usage
Land Access: Variable, depending on whether you own your land or need to purchase a permit

Unique Insight: Consider renting some of the more expensive tools, like a log splitter, if you only need them occasionally.

Case Study: The Sustainable Firewood Project

I once worked with a small community in the Appalachian Mountains to develop a sustainable firewood project. The goal was to provide affordable firewood to low-income families while also promoting responsible forest management.

We started by identifying a stand of timber that needed thinning. We then trained local residents in safe and efficient wood processing techniques. We used a combination of chainsaws, wedges, and log splitters to harvest and process the wood.

The project was a huge success. We were able to provide firewood to dozens of families, while also improving the health and productivity of the forest. The project also created jobs and stimulated the local economy.

Common Pitfalls to Avoid: Learning from Mistakes

Ignoring Safety: Always wear appropriate safety gear and follow safe operating procedures.
Using a Dull Chain: A dull chain is dangerous and inefficient.
Overworking Yourself: Take breaks and don’t try to do too much at once.
Neglecting Maintenance: Regular maintenance is essential for keeping your chainsaw running smoothly.
Cutting Green Wood: Green wood is difficult to light and burns poorly.
Improper Stacking: Stacking wood improperly can prevent it from drying properly.

Next Steps: Level Up Your Wood Game

Now that you have these hacks under your belt, it’s time to put them into practice. Here are a few suggestions for next steps:
