Repairing a Chainsaw Chain: A Comprehensive Guide

When it comes to chainsaw chains, regular maintenance is key to ensuring their longevity and optimal performance. While some repair jobs may seem daunting, understanding the basics can help you tackle common issues. Whether you need to sharpen the chain, replace damaged links, adjust tension, or simply clean it, this guide will walk you through the process. Let's explore the different repair methods and the tools you'll need to get started.

Sharpening the Chain

If the chain is dull, the first step is to sharpen the teeth. This is a straightforward process that requires a chainsaw file or a sharpening tool. It's important to follow the manufacturer's specifications for the correct angle and depth.

Tools Needed:

Chainsaw file or sharpening tool Safety gear Gloves Eye protection

Replacing Damaged Links

When damaged links are present, replacing them is a more involved process. To do this successfully, you will need a chain repair tool to remove the damaged links and replace them with new ones. This method ensures that the chain remains functional and safe for continued use.

Tools Needed:

Chain repair tool New chain links Gloves Eye protection

Steps to Replace Damaged Links:

Identify the damaged links on the chain. Use a chain repair tool to remove the damaged links. Clip the new links onto the chain. Ensure the chain is secure and in place.

Adjusting Tension

A loose or overly tight chain can affect the chainsaw's performance. Adjusting the tension is a simple process that can be done using a tensioning screw on the chainsaw. This step ensures the chain operates within the optimal range for efficient cutting.

Tools Needed:

Screwdriver or wrench Gloves Eye protection

Steps to Adjust Tension:

Locate the tensioning screw on the chainsaw. Loosen or tighten the screw as needed. Check the chain tension by pulling it away from the guide bar. Ensure the chain is neither too loose nor too tight.

Cleaning the Chain

A thorough cleaning can restore the chain's performance by removing sap, dirt, and debris. This is a preventive measure that can extend the life of the chain and improve its efficiency. Use a cleaning brush to remove any buildup effectively.

Steps to Clean the Chain:

Disconnect the chainsaw from the power source or remove the battery. Wear protective gear. Use a cleaning brush to scrub away dirt and debris. Rinse the chain with water and let it dry completely.

Replacing the Chain

In cases where the chain is excessively worn or damaged past repair, it may be more practical to replace it entirely. Knowing the exact measurements and specifications is crucial to ensuring a proper fit. The most common chain division is 3/8 inch, as shown in the image below.

Important on the Cutter: Maintain them properly. The angle at which to sharpen the cutters on your chain differs depending on the wood type. Softwoods like conifers, willows, poplars, require different angles than hardwoods such as oak, cherry, pear, hornbeam.
