2. Understanding Chain Types and Gauges

The chain is the heart of your chainsaw’s cutting ability. Selecting the right chain type and gauge is essential for efficient and safe operation. The MS 180 C typically uses a 3/8″ Picco Micro (PM3) chain with a .050″ gauge.

• Chain Types:
  • Full Chisel: These chains have square-cornered cutters that provide the fastest cutting speed. However, they dull quickly and are best suited for clean wood. I tend to avoid these for general use due to their rapid dulling.
  • Semi-Chisel: These chains have rounded cutters that are more durable and forgiving when cutting dirty or frozen wood. I find these to be a great all-around choice for most firewood cutting.
  • Low-Profile (Micro-Lite): These chains are designed for smaller chainsaws like the MS 180 C. They have a narrow kerf (cutting width), which reduces the amount of power required to cut through wood.
• Chain Gauge: The gauge refers to the thickness of the drive links that fit into the guide bar groove. Using the correct gauge is crucial for proper chain fit and safety. The MS 180 C requires a .050″ gauge chain.
• Drive Links: The number of drive links determines the chain’s length and is specific to the bar length. For a 16-inch bar on the MS 180 C, you’ll typically need a chain with 55 drive links.
• My Experience: I once accidentally purchased a chain with the wrong gauge. It was too loose on the bar, causing excessive vibration and making it difficult to control the chainsaw. I quickly learned the importance of verifying the correct gauge and drive link count before installing a new chain.

Takeaway: Use a 3/8″ Picco Micro (PM3) semi-chisel chain with a .050″ gauge and the correct number of drive links (typically 55 for a 16-inch bar).

3. Chain Sharpening Techniques

A sharp chain is essential for efficient cutting, safety, and reducing wear on your chainsaw. A dull chain requires more force to cut, increasing the risk of kickback and straining the engine. I sharpen my chains regularly to maintain peak performance.

  • File Guide: A file guide helps maintain the correct filing angle and depth.
  • Depth Gauge Tool: This tool is used to check and adjust the depth gauges (rakers) on the chain.
• Sharpening Procedure:
  1. Secure the Chainsaw: Clamp the guide bar in a vise or use a bar-mounted filing tool to stabilize the chainsaw.
  2. Identify the Sharpening Angle: The correct sharpening angle for the MS 180 C chain is typically marked on the file guide.
  3. File the Cutters: Hold the file guide against the chain and file each cutter with smooth, even strokes. File from the inside of the cutter towards the outside. Maintain the correct angle and depth.
  4. Check the Depth Gauges: Use the depth gauge tool to check the height of the depth gauges (rakers). If they are too high, file them down slightly using a flat file.
  5. Repeat for All Cutters: Sharpen all the cutters on the chain, ensuring they are all the same length and shape.
• Frequency of Sharpening: I typically sharpen my chain after every 2-3 tanks of fuel or whenever I notice a decrease in cutting performance. If the chain hits dirt or rocks, I sharpen it immediately.
• My Experience: I used to neglect chain sharpening, thinking it wasn’t that important. However, I quickly realized that a sharp chain not only cuts faster but also requires less effort, reducing fatigue and improving safety. Now, I make it a habit to sharpen my chain regularly.
