Expert Tip #1: Master the Art of Proper Chain Sharpening

A dull chain is not only inefficient, but it’s also dangerous. It forces you to apply more pressure, increasing the risk of kickback and fatigue. Sharpening your chain regularly is the single most important thing you can do to improve your MS311’s performance.

Why Sharpening Matters (and How it Saves You Money)

I remember one time, I was helping a friend clear some overgrown brush on his property. He was struggling with his chainsaw, complaining that it was underpowered. After a quick inspection, I realized his chain was incredibly dull. After a few minutes with a file, his saw was cutting like new.

A sharp chain:

Cuts faster and more efficiently: This means you’ll use less fuel and spend less time on each cut.
Reduces wear and tear on the saw: A dull chain forces the engine to work harder, leading to premature wear on the piston, cylinder, and other components.
Improves safety: A sharp chain bites into the wood cleanly, reducing the risk of kickback and allowing you to maintain better control.
Saves you money: By reducing fuel consumption, extending the life of your saw, and improving safety, proper chain sharpening can save you a significant amount of money over time.

The Sharpening Process: A Step-by-Step Guide

Secure the Saw: Place the chainsaw in a vise or use a bar clamp to hold it securely.
Identify the Correct File Size: Refer to your Stihl MS311 manual for the recommended file size for your chain type. Typically a 5/32″ (4.0 mm) or 3/16″ (4.8 mm) round file will work.
Use a Filing Guide: A filing guide helps you maintain the correct angle and depth while sharpening. Stihl offers a variety of filing guides specifically designed for their chains.
Sharpen Each Cutter: Hold the file at the correct angle (typically 30 degrees) and file each cutter from the inside out, using smooth, consistent strokes. Pay attention to the depth gauge (raker) height.
Maintain Depth Gauges (Rakers): Use a flat file and a depth gauge tool to maintain the correct height of the depth gauges. These control how aggressively the chain bites into the wood. Too high, and the chain will chatter and cut poorly. Too low, and the chain will grab too much wood, increasing the risk of kickback.
Check for Consistency: Ensure that all cutters are sharpened to the same length and angle.
Deburr the Cutters: Use a small, fine-grit file to remove any burrs from the cutting edges.

Personal Experience: I’ve found that using a filing guide is essential for maintaining consistent sharpening angles, especially when I’m sharpening in the field. It’s a small investment that pays off in improved cutting performance and chain longevity.
