Stihl Chainsaw Chain

To find the chain size on a Stihl chainsaw, check the guide bar for model numbers or measure chain pitch and gauge; common sizes include 3/8″ and .325″.

Discovering the correct chain size for your Stihl chainsaw is crucial for both safety and performance. A chainsaw’s chain must fit precisely on the saw’s guide bar. Moreover, using the correct size ensures that your chainsaw functions efficiently and maintains longevity. In this guide, we will help you identify the chain size on your Stihl chainsaw and provide useful tips for its maintenance.

Understanding Chainsaw Chain Measurements

There are three critical dimensions to consider when finding your Stihl chainsaw chain size: the pitch, the gauge, and the number of drive links. Here’s what each of these terms means and how you can measure them.

Pitch Of The Chain

The pitch is the distance between any three consecutive rivets divided by two. It represents the spacing between the links on the chain. Common pitch sizes include 1/4″, 3/8″ low profile, 3/8″, and .404″.

Gauge Of The Chain

The gauge denotes the thickness of the drive links and is important for the chain’s fit in the guide bar. Standard gauges range from .043″ to .063″.

The total number of drive links on the chain must complement the length of the guide bar. Drive links are the part of the chain that sit in the groove of the guide bar.

How to Identify Your Stihl Chainsaw Chain Size

  1. Locate the numbers on your Stihl chainsaw. These are usually found on the guide bar and can provide a quick reference for your chain size.
  2. Measure the guide bar length from the front tip of the saw back to where it emerges from the housing. This is important since the length of the guide bar often determines the required number of drive links.
  3. Use a caliper or a pitch gauge tool to measure the pitch and gauge of your existing chain.

Ensuring Your Stihl Chainsaw Chain Lasts

Maintaining the longevity of your Stihl chainsaw chain involves regular maintenance and proper use. Here are some quick tips:

  • Regular sharpening: Keeping your chain sharp ensures efficient cuts and reduces the strain on your chainsaw.
  • Proper tension: A chain that’s too tight can wear out quickly, while a loose chain can be dangerous. Check the tension before each use.
  • Clean after use: Remove debris and sap after each use to prevent build-up, which can degrade the chain over time.
  • Use the right oil: Always use the manufacturer’s recommended bar and chain oil for optimal performance.
