Stihl MS180C Chainsaw Chain Tips: 5 Pro Guide Insights

1. Understanding Your MS180C Chain: Specs, Types, and Selection

Before we get to the nitty-gritty, let’s talk about understanding your chain. It’s not just a loop of metal; it’s a precision-engineered component crucial to your saw’s performance.

Chain Specifications:

The Stihl MS180C typically uses a 3/8″ Picco Micro Comfort 3 (PMC3) chain. Here’s what that means:

• 3/8″ Pitch: This refers to the distance between three rivets divided by two. It’s a standard pitch for smaller chainsaws and provides a good balance of cutting speed and smoothness.
• Picco Micro Comfort 3 (PMC3): This is a specific chain type designed for lightweight saws like the MS180C. It’s known for its low vibration and smooth cutting action.
• Gauge: The gauge refers to the thickness of the drive links that fit into the guide bar groove. For the MS180C, the gauge is usually .050″ (1.3mm).

Why are these specs important? Using the wrong chain can damage your saw and be extremely dangerous. The wrong pitch can cause the chain to jump off the bar, while the wrong gauge might not fit properly, leading to chain breakage and kickback.

Chain Types:

While the PMC3 is a common choice, you might encounter other chain types:

• Low-Kickback Chains: These chains are designed with safety in mind, featuring bumper drive links that reduce the risk of kickback. If you’re a beginner, I highly recommend using a low-kickback chain.
• Full-Chisel Chains: These chains have square-cornered cutters that provide aggressive cutting, but they are more prone to kickback and require more skill to sharpen properly. I wouldn’t recommend these for the MS180C unless you’re an experienced user.
• Semi-Chisel Chains: These chains have rounded cutters that are more forgiving and stay sharp longer than full-chisel chains. They’re a good compromise for general use.

Chain Selection:

Choosing the right chain depends on the type of wood you’re cutting and your experience level. For general use around the home, a low-kickback or semi-chisel chain is ideal. If you’re cutting hardwoods like oak or maple, you might consider a more aggressive chain, but always prioritize safety.

My Experience: I remember one time, early in my firewood-cutting days, I tried using an aggressive full-chisel chain on my MS180C to speed things up. The result? A lot of kickback and a very close call. I quickly learned that matching the chain to the saw and the task is crucial. Stick with the recommended PMC3 or a similar semi-chisel chain for most jobs.

Key Takeaway: Know your chain specs. The Stihl MS180C typically uses a 3/8″ pitch, .050″ gauge PMC3 chain. Choose a chain type that matches your experience level and the type of wood you’re cutting.

2. Mastering the Art of Chainsaw Chain Sharpening: A Step-by-Step Guide

A sharp chain is a safe chain. A dull chain requires more force, increasing the risk of kickback and putting unnecessary strain on your saw. Sharpening your chain regularly is essential for efficient and safe cutting.

Tools You’ll Need:

• Chainsaw File: This is a round file specifically designed for sharpening chainsaw chains. The correct size for the MS180C chain is typically 5/32″ (4.0mm).
• File Guide: This tool helps you maintain the correct sharpening angle and depth. Stihl offers excellent file guides specifically for their chains.
• Depth Gauge Tool: This tool is used to check and adjust the depth gauge (raker) height.
• Flat File: This file is used to lower the depth gauges.
• Gloves: Protect your hands from sharp cutters.
• Vice or Chainsaw Vise: This will hold the chainsaw securely while you sharpen the chain.

Step-by-Step Sharpening Guide:

1. Secure the Chainsaw: Place your chainsaw in a vise or chainsaw vise to keep it stable.

2. Identify the Cutters: Observe the cutters on your chain. You’ll notice they have a top plate and a side plate. The cutting edge is formed where these two plates meet.

3. Set the Sharpening Angle: The correct sharpening angle is crucial for optimal performance. For the MS180C chain, the recommended angle is typically 30 degrees for the top plate and 60 degrees for the side plate. Your file guide will help you maintain these angles.

4. Sharpen the Cutters: Place the file guide on the chain, aligning it with the cutter you’re about to sharpen. Insert the chainsaw file into the guide and, using smooth, even strokes, file the cutter from the inside out. Apply gentle pressure on the forward stroke and release on the return stroke. Typically, 3-5 strokes per cutter are sufficient.

5. Maintain Consistent Strokes: It’s important to maintain consistent strokes and pressure on each cutter to ensure uniform sharpening.

6. Sharpen All Cutters on One Side: Sharpen all the cutters on one side of the chain before moving to the other side. This helps maintain balance and consistency.

7. Repeat on the Other Side: Rotate the chainsaw in the vise and repeat the sharpening process on the other side of the chain.

8. Check Depth Gauges: After sharpening, check the depth gauges (rakers) with a depth gauge tool. These gauges control the amount of wood the cutter takes with each pass. If the depth gauges are too high, the chain will grab and cause kickback. If they’re too low, the chain won’t cut effectively.

9. Lower Depth Gauges (If Necessary): If the depth gauges are too high, use a flat file to carefully lower them. File them down evenly until they are flush with the depth gauge tool.

10. Final Check: After sharpening, rotate the chain and inspect each cutter to ensure they are all sharp and uniform.

Pro Tips:

• Sharpen Regularly: Don’t wait until your chain is completely dull. Sharpen it after every few tanks of gas or whenever you notice a decrease in cutting performance.
• File in One Direction: Always file in one direction (from the inside out) to avoid damaging the cutter.
• Use a File Guide: A file guide is essential for maintaining the correct sharpening angle and depth.
• Clean the Chain: Before sharpening, clean the chain with a wire brush to remove dirt and debris.
• Don’t Over-Sharpen: Over-sharpening can weaken the cutters and shorten the life of your chain.
• Take Breaks: Sharpening can be tiring, so take breaks to avoid making mistakes.

My Experience: I used to think I could get away with sharpening my chain “by eye.” I’d just eyeball the angle and go to town with the file. The result? A chain that was sharp in some spots and dull in others. My cuts were uneven, and my saw was working harder than it needed to. Investing in a good file guide was a game-changer. It ensured consistent sharpening and made the whole process much easier.

Key Takeaway: Sharpen your chain regularly using the correct tools and techniques. A sharp chain is a safe chain. Use a file guide to maintain the correct sharpening angle and depth.

3. Chainsaw Chain Tensioning: Finding the Sweet Spot

Proper chain tension is crucial for safe and efficient cutting. A chain that’s too loose can derail, while a chain that’s too tight can bind and overheat, damaging the bar and sprocket.

How to Check Chain Tension:

1. Turn Off the Chainsaw: Always turn off the chainsaw and engage the chain brake before checking or adjusting chain tension.
2. Wear Gloves: Protect your hands from the sharp cutters.
3. Locate the Tensioning Screw: The tensioning screw is typically located on the side of the chainsaw, near the bar.
4. Loosen the Bar Nuts: Use a wrench to slightly loosen the bar nuts that hold the bar in place. You don’t need to remove them completely; just loosen them enough to allow the bar to move.
5. Adjust the Tensioning Screw: Use a screwdriver to turn the tensioning screw. Turning it clockwise will tighten the chain, while turning it counterclockwise will loosen it.
6. Check the Tension: The chain should be snug against the bar but still able to be pulled around 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 of the bar.
7. Tighten the Bar Nuts: Once you’ve achieved the correct tension, tighten the bar nuts securely.

Tips for Maintaining Proper Chain Tension:

• Check Tension Regularly: Check the chain tension before each use and after every few cuts. New chains tend to stretch more quickly, so you’ll need to check the tension more frequently during the first few hours of use.
• Adjust Tension When Hot: The chain will expand as it heats up during use, so it’s important to adjust the tension when the chain is hot. After making a few cuts, check the tension and adjust as needed.
• Don’t Over-Tighten: Over-tightening the chain can damage the bar and sprocket. The chain should be able to move freely around the bar.
• Clean the Bar and Sprocket: Regularly clean the bar and sprocket to remove dirt and debris. This will help prevent the chain from binding and overheating.
• Replace Worn Sprocket: A worn sprocket can cause the chain to skip and wear unevenly. Replace the sprocket when it shows signs of wear.

My Experience: I once ignored a slightly loose chain, thinking it wouldn’t be a big deal. After a few aggressive cuts, the chain derailed, snapping back and hitting my protective chaps. Luckily, I was wearing proper safety gear, but it was a stark reminder of the importance of proper chain tension. Now, I check the tension religiously before every use.

Key Takeaway: Proper chain tension is crucial for safety and efficiency. Check the tension regularly, especially when the chain is new or hot. The chain should be snug against the bar but still able to be pulled around by hand.

4. Chainsaw Chain Lubrication: Keeping Things Running Smoothly

Proper lubrication is essential for extending the life of your chain and bar. Without lubrication, the chain will overheat and wear out quickly, and the bar will become damaged.

Types of Chain Oil:

• Bar and Chain Oil: This is a specially formulated oil designed for use in chainsaws. It’s typically a high-viscosity oil that clings to the chain and bar, providing excellent lubrication and protection.
• Vegetable-Based Oil: This is an environmentally friendly alternative to petroleum-based bar and chain oil. It’s biodegradable and less harmful to the environment.
• Motor Oil: While motor oil can be used in a pinch, it’s not recommended for regular use. It’s not as viscous as bar and chain oil, so it doesn’t provide as much lubrication.

How to Lubricate Your Chain:

1. Fill the Oil Reservoir: Before each use, fill the oil reservoir with bar and chain oil. The reservoir is typically located on the side of the chainsaw, near the fuel tank.
2. Adjust the Oil Flow: Most chainsaws have an adjustable oil flow. Start with the oil flow set to the maximum setting and adjust it as needed. The oil flow should be sufficient to keep the chain and bar lubricated without excessive oil consumption.
3. Check the Oil Output: To check the oil output, hold the chainsaw over a piece of cardboard or wood and rev the engine. You should see a steady stream of oil coming from the chain.
4. Clean the Oiler: Regularly clean the oiler to prevent it from becoming clogged. The oiler is typically located near the bar mount.

Tips for Proper Chain Lubrication:

• Use the Right Oil: Use a high-quality bar and chain oil specifically designed for chainsaws.
• Check Oil Level Regularly: Check the oil level before each use and refill as needed.
• Adjust Oil Flow: Adjust the oil flow to match the cutting conditions. When cutting hardwoods or in hot weather, you’ll need more oil.
• Clean the Oiler: Regularly clean the oiler to prevent it from becoming clogged.
• Store Chainsaw Properly: When storing your chainsaw, empty the oil reservoir to prevent the oil from gumming up the oiler.

My Experience: I once ran my chainsaw without checking the oil level. The result? A smoking chain and a severely damaged bar. I learned the hard way that proper lubrication is non-negotiable. Now, I make it a habit to check the oil level before every use and to clean the oiler regularly.

Key Takeaway: Proper lubrication is essential for extending the life of your chain and bar. Use a high-quality bar and chain oil, check the oil level regularly, and clean the oiler to prevent it from becoming clogged.
