A chainsaw is an essential tool for cutting wood and other materials. Over time, the chainsaw blade can become dull and less effective, making it more difficult to use. A chainsaw sharpener is a tool used to sharpen the chainsaw blade and restore its cutting ability. In this article, we will go over how to use a round file to sharpen a chainsaw.

What are the different ways of sharpening a chainsaw?

There are several different ways to sharpen a chainsaw blade, and the method you choose will depend on your personal preference, skill level, and the tools you have available. Here are the two most common methods for sharpening a chainsaw:

  1. Electric Chainsaw Sharpener – An electric chainsaw sharpener is a specialized tool that allows you to sharpen the chainsaw blade quickly and accurately. It uses a grinding wheel to sharpen the cutting teeth on the chainsaw blade.
  2. Manual Chainsaw File – A manual chainsaw file is a simple tool that can be used to sharpen the cutting teeth on the chainsaw blade. It consists of a small metal file that fits into the grooves on the chainsaw teeth. The file is used to sharpen the cutting edge of the tooth and restore its sharpness.

How to Use a Chainsaw Sharpener (Manual chainsaw file)

Using a chainsaw sharpener is relatively simple, but it is important to follow the manufacturer’s instructions carefully. Here are the basic steps for using a chainsaw sharpener:

Secure the Chainsaw

Before sharpening the chainsaw, it is important to secure it in a vise or other holding device to prevent it from moving while sharpening. Make sure the chainsaw is secure and stable before proceeding.

Check the Chain Tension

Check the tension of the chainsaw chain and adjust it if necessary. A loose chain can cause damage to the chainsaw and create an unsafe working condition.

Determine the File Size

Select the right file size for your chainsaw blade. The file size should match the size of the teeth on the chainsaw blade.

Adjust the Depth Gauge

The depth gauge on the chainsaw blade needs to be adjusted to the correct height before sharpening. Follow the manufacturer’s instructions for adjusting the depth gauge.

Sharpen the Teeth

Start by filing the tooth that is furthest from you. Place the file into the groove on the tooth and use a back-and-forth motion to sharpen the cutting edge of the tooth. Be sure to file each tooth at the same angle and with the same number of strokes to ensure even sharpening.

Check the Teeth Height

After sharpening, use a gauge to check the height of the teeth on the chainsaw blade. Make sure the teeth are all the same height and sharpen any that are not.

Lubricate the Chain

After sharpening, lubricate the chainsaw chain with oil to prevent rust and keep it working smoothly.

In conclusion, a chainsaw sharpener is an essential tool for anyone who uses a chainsaw regularly. By following the manufacturer’s instructions carefully, you can sharpen your chainsaw blade and restore its cutting ability quickly and easily. Remember to wear protective gear when using a chainsaw sharpener and take your time to ensure a safe and effective sharpening process.
