What Size File Do I Need for My Husqvarna Chainsaw: Sharpen Smart



What Size File Do I Need for My Husqvarna Chainsaw

For a Husqvarna chainsaw, select a file size matching your chain’s pitch: typically 3/16″, 5/32″, or 7/32″ for the most common chain types.

Maintaining your Husqvarna chainsaw is crucial for its performance and longevity. One of the key aspects of maintenance is sharpening the chain, and for that, you will need the right file size. This comprehensive guide will help you determine which size file you need for your chainsaw to keep it running smoothly.

Understanding Chainsaw Chain Measurements

Before diving into file sizes, it’s important to understand the measurements that correspond to different chainsaw chains. Chainsaw chains are categorized by:

  • Pitch – The distance between three consecutive rivets divided by two.
  • Gauge – The width of the groove in the bar that the chain fits into.
  • Drive link count – The number of drive links in the chain.

These measurements will guide you in selecting the correct file size for your chainsaw chain.

Identifying Your Husqvarna Chainsaw Chain Size

To find the proper file size, first identify your chainsaw model. This information is usually found on a label on the chainsaw. Once you have the model number, consult your Husqvarna owner’s manual or the Husqvarna website for specific chain specifications.

How to Select the File Size Based on Chain Specifications

If you do not have the model number readily available, you can still determine the file size by measuring the chain itself. Here’s how to do it:

  1. Analyse the chain pitch and gauge using a chainsaw gauge measurement tool or by manual calculation.
  2. Match the chain pitch to the recommended file diameter. For example, a chainsaw chain with a .325″ pitch typically requires a 4.8mm or 3/16″ round file.
  3. If your chain has a different pitch not listed above, refer to the manufacturer’s guidelines for the correct file size.

Tips for Sharpening Your Chainsaw Chain

Having the right file size is just the first step. Here are some tips to ensure you sharpen your chainsaw chain correctly:

  • Always wear protective gloves to prevent cuts and ensure a firm grip.
  • Secure your chainsaw in a vise or clamp during sharpening to prevent movement.
  • Follow the angle of the top plate of the cutter; it’s usually around 30 degrees.
  • Use smooth, consistent strokes with the file, applying slight pressure.
  • Count your strokes and apply the same number to each cutter for uniform sharpness.
  • Check your owner’s manual for detailed instructions specific to your model.
