Selecting the correct sharpening tools is essential for maintaining the performance and safety of your Stihl chainsaw.

This guide helps you instantly identify the correct Standard File Kit or 2-in-1 EasyFile based on the gauge code stamped directly onto your chain's depth gauge. By matching your chain's physical markings to the specifications below, you can ensure a professional-grade edge every time you sharpen.

Choosing the correct File Kit...

Frequently Asked Questions (FAQ)

How do I find the "Gauge Code" on my Stihl chain? Look at the side of the depth gauge (the shark-fin shaped tooth in front of the cutter). There is a small number stamped into the metal (e.g., 1, 2, or 3). This number corresponds to the chain pitch and the required file size.

What is the difference between a Standard File Kit and a 2-in-1 EasyFile?

  • Standard File Kit: Includes a round file with a guide for sharpening the cutter and a flat file with a depth gauge tool for lowering the gauge.
  • 2-in-1 EasyFile: A specialized tool that sharpens the saw tooth and lowers the depth gauge simultaneously in a single stroke, saving time and ensuring accuracy.

Example: What size file do I need for a 3/8" Picco chain? For a 3/8" Picco chain (Gauge Code 6), you should use a 4.0mm round file.
