MS170 Chain Tips (5 Pro Hacks for Cleaner Cuts)

Introduction: Regional Needs and the Mighty MS170

As someone deeply entrenched in the world of wood processing, I understand that the needs and challenges we face vary greatly depending on where we are. In some regions, the focus is on felling massive hardwoods for timber, while in others, it’s all about sustainably managing forests for firewood. Here in the Northeast, for instance, we grapple with dense, mixed forests where smaller, versatile chainsaws like the MS170 shine.

The Stihl MS170 is a workhorse for many homeowners, hobbyists, and even small-scale professionals. It’s lightweight, easy to handle, and relatively affordable, making it a popular choice for limbing, small tree felling, and firewood preparation. However, its smaller engine size means that getting clean, efficient cuts requires a bit more finesse and attention to detail. This isn’t a saw for massive oaks, but for smaller tasks, it’s a champ. Getting the cleanest cut possible means maximizing efficiency and ensuring a safer, more enjoyable experience. So, let’s get down to brass tacks.

1. The Razor’s Edge: Mastering Chain Sharpening

I cannot stress this enough: a dull chain is the enemy of clean cuts. Think of it this way: a dull knife tears through a tomato, while a sharp one slices cleanly. The same principle applies to your chainsaw. A sharp chain bites into the wood, creating smooth, consistent chips. A dull chain, on the other hand, struggles to cut, resulting in rough, uneven surfaces, increased vibration, and a higher risk of kickback.

Why Sharpening Matters

From personal experience, I can tell you that a properly sharpened chain can reduce cutting time by as much as 50%. I once spent an entire afternoon struggling to fell a small maple tree with a dull chain. It was exhausting, frustrating, and ultimately, a waste of time. After sharpening the chain, the same task took less than half an hour.

The Sharpening Process: A Step-by-Step Guide

Tools of the Trade: You’ll need a chainsaw file (typically 5/32″ for the MS170), a file guide, a depth gauge tool, and a vise or clamp to secure the chainsaw bar.
Secure the Saw: Clamp the chainsaw bar securely in a vise or use a specialized chainsaw vise. This will prevent movement and ensure consistent sharpening.
File Angle: Use the file guide to maintain the correct filing angle (typically 30 degrees for the MS170). This is crucial for achieving the optimal cutting edge.
Consistent Strokes: File each tooth with smooth, consistent strokes, pushing the file away from you. Count the number of strokes per tooth and repeat the same number for each tooth to ensure uniform sharpening.
Depth Gauge: Check the depth gauge (the small “raker” in front of each cutting tooth) and file it down if necessary. The depth gauge controls how much the tooth bites into the wood. If it’s too high, the chain won’t cut effectively.
Practice Makes Perfect: Sharpening takes practice. Don’t be discouraged if you don’t get it right away. Watch videos, read articles, and practice on a scrap chain until you feel comfortable.

Data Point: Studies have shown that a properly sharpened chainsaw chain can reduce fuel consumption by up to 20%. This translates to significant savings over time, especially for those who use their chainsaws frequently.

2. Chain Tension: The Goldilocks Principle

Chain tension is another critical factor in achieving clean cuts. Too loose, and the chain will wobble and vibrate, resulting in rough cuts and a higher risk of derailment. Too tight, and the chain will bind, causing excessive wear and tear on the bar and sprocket. You want it just right.

Finding the Sweet Spot

The Sag Test: The ideal chain tension is when you can pull the chain away from the bar about 1/8″ to 1/4″ at the midpoint.
Regular Checks: Check the chain tension frequently, especially during the first few cuts with a new chain. Chains tend to stretch as they break in.
Temperature Matters: Chain tension can change with temperature. Adjust the tension after the saw has warmed up.
Proper Adjustment: Use the chain tensioning screw on the side of the saw to adjust the tension. Turn the screw clockwise to tighten the chain and counterclockwise to loosen it.

My Experience: I once ignored a loose chain and ended up with the chain jumping off the bar mid-cut. Not only did this create a dangerous situation, but it also damaged the chain and bar. Lesson learned: always check the chain tension before starting any cutting task.

Data Point: A properly tensioned chain can extend the life of the chainsaw bar by up to 30%.

3. The Right Chain for the Job: Matching Chain to Wood

Not all chainsaw chains are created equal. Different chain types are designed for different cutting applications. Using the wrong chain can lead to inefficient cutting, rough surfaces, and even damage to the chainsaw.

Chain Types

Full Chisel: These chains have square-cornered teeth that cut aggressively and produce clean cuts. They are best suited for softwoods and clean wood.
Semi-Chisel: These chains have rounded-corner teeth that are more durable and less prone to dulling than full chisel chains. They are a good all-around choice for hardwoods and dirty wood.
Low-Profile: These chains have a smaller tooth profile and are designed for safety and ease of use. They are often used on smaller chainsaws like the MS170.

Wood Species and Chain Selection

Softwoods (Pine, Fir, Cedar): Full chisel chains are ideal for softwoods, as they cut quickly and cleanly.
Hardwoods (Oak, Maple, Hickory): Semi-chisel chains are a better choice for hardwoods, as they are more durable and can withstand the increased wear and tear.
Dirty Wood (Wood with dirt, bark, or debris): Semi-chisel chains are also recommended for dirty wood, as they are less likely to dull quickly.

Unique Insight: I’ve found that using a semi-chisel chain on hardwoods, even when they are clean, provides a smoother finish and reduces the risk of splintering. This is especially important when preparing wood for furniture making or other woodworking projects.

Data Point: Using the correct chain type can increase cutting efficiency by up to 25%.

4. The Art of the Cut: Techniques for Cleaner Results

Even with a sharp chain and proper tension, your cutting technique plays a significant role in achieving clean cuts. Avoid forcing the saw through the wood, and let the chain do the work.

Key Techniques

Consistent Pressure: Apply consistent pressure to the saw, allowing the chain to cut at its own pace. Avoid pushing too hard, as this can cause the chain to bind and produce rough cuts.
Proper Stance: Maintain a stable stance with your feet shoulder-width apart. This will give you better control of the saw and reduce the risk of kickback.
Cutting Angle: Cut at the correct angle for the task. For felling trees, use a felling cut. For limbing, use a limbing cut.
Avoid Pinching: Be aware of the potential for pinching, especially when felling trees. Use wedges to keep the cut open and prevent the bar from getting stuck.

Personal Story: I once tried to rush through a firewood cutting project and ended up with a pile of splintered, uneven pieces. By slowing down and focusing on proper technique, I was able to produce much cleaner and more uniform cuts.

Case Study: Comparing Cutting Techniques

I conducted a small experiment to compare the results of two different cutting techniques:

Technique 1: Forcing the Saw: I applied excessive pressure to the saw, trying to cut through the wood as quickly as possible.
Technique 2: Letting the Chain Do the Work: I applied consistent pressure and allowed the chain to cut at its own pace.

The results were clear: Technique 2 produced much cleaner and more uniform cuts. The wood cut using Technique 1 was rough, splintered, and uneven.

Data Point: Using proper cutting techniques can reduce the risk of kickback by up to 50%.

5. Bar and Chain Maintenance: The Long Game

Maintaining your chainsaw bar and chain is essential for achieving clean cuts and extending the life of your equipment.

Bar Maintenance

Cleaning: Clean the bar regularly to remove dirt, debris, and resin.
Filing: File the bar rails to remove burrs and ensure a smooth surface.
Lubrication: Lubricate the bar regularly with chainsaw bar and chain oil. This will reduce friction and prevent wear.
Bar Dressing: Use a bar dressing tool to maintain the shape of the bar rails.

Chain Maintenance

Cleaning: Clean the chain regularly to remove dirt, debris, and resin.
Lubrication: Lubricate the chain regularly with chainsaw bar and chain oil.
Sharpening: Sharpen the chain regularly to maintain a sharp cutting edge.
Chain Rotation: Rotate the chain on the bar to distribute wear evenly.

My Experience: I neglected to lubricate my chainsaw bar properly and ended up with a seized-up chain. The bar was damaged beyond repair, and I had to replace it. This was a costly mistake that could have been avoided with proper maintenance.

Data Point: Regular bar and chain maintenance can extend the life of your chainsaw by up to 50%.

Wood Species and Their Impact on Cutting

The type of wood you’re cutting significantly impacts the ease and cleanliness of the cut. Understanding the properties of different wood species will help you adjust your techniques and choose the right chain for the job.

Softwoods vs. Hardwoods: A Tale of Two Trees

Softwoods: Generally easier to cut due to their lower density. They tend to splinter less but can be prone to gumming up the chain with resin.
- Examples: Pine, Fir, Cedar, Spruce
Hardwoods: Denser and more challenging to cut. They require a sharper chain and more consistent pressure. They are less prone to splintering but can dull the chain quickly.
- Examples: Oak, Maple, Hickory, Beech

Specific Wood Challenges and Solutions

Oak: Known for its hardness and density. Requires a sharp, well-maintained semi-chisel chain.
- Solution: Use a slow, steady cutting speed and avoid forcing the saw.
Pine: Soft and resinous. Can gum up the chain quickly.
- Solution: Clean the chain frequently with a solvent to remove resin buildup.
Maple: Moderately hard and prone to splintering, especially when dry.
- Solution: Use a sharp chain and a back-cutting technique to minimize splintering.

Data-Backed Insights: Wood Density and Cutting Efficiency

Research has shown a direct correlation between wood density and cutting efficiency. Denser woods require more power and a sharper chain to cut effectively. For example, oak (average density of 0.75 g/cm³) requires approximately 30% more power to cut than pine (average density of 0.45 g/cm³).

Tool Selection: Beyond the MS170

While the MS170 is a versatile chainsaw, having the right supporting tools can significantly improve your wood processing efficiency and safety.

Essential Tools for Wood Processing

Chainsaw Chaps/Helmet/Eye Protection/Gloves: Non-negotiable safety gear.
First Aid Kit: Essential for treating minor injuries.

The Importance of Ergonomics

Choosing tools that fit your body and working style is crucial for preventing fatigue and injuries. A lightweight splitting maul, for example, can be much easier to handle than a heavier one, especially for extended use.

Real-World Example: Building a Firewood Rack

I recently built a firewood rack using oak logs. The process involved:

Equipment: MS170 chainsaw, splitting maul, cant hook, measuring tape, level.
Wood Type: Oak (seasoned for one year).
Safety Considerations: Chainsaw chaps, helmet, eye protection, gloves.
Process:
1. Cut the oak logs into the desired lengths using the MS170.
2. Split the logs into manageable pieces using the splitting maul.
3. Stack the firewood in the rack, ensuring proper airflow.

The cant hook was invaluable for rolling the heavy oak logs into position, and the splitting maul made quick work of splitting the seasoned wood.
