Understanding Chainsaw Chains
Before we dive into the repair process, it’s important to have a basic understanding of chainsaw chains. Chainsaw chains are made up of a series of interconnected cutting links, which are held together by drive links. The cutting links have sharp teeth that cut through wood, while the drive links engage with the chainsaw’s sprocket, propelling the chain around the guide bar.
Chainsaw chains can become loose or damaged for a variety of reasons, including:
- Wear and tear over time
- Contact with rocks or other hard objects
- Improper tensioning
- Lack of lubrication
If you suspect that your chainsaw chain is loose or damaged, it’s important to fix it as soon as possible. A loose or damaged chain can be dangerous and can also damage the chainsaw itself.
Tools You’ll Need
To fix a chainsaw chain, you’ll need the following tools:
- Screwdriver or wrench
- Chain tensioning tool or flathead screwdriver
- Chain file and file guide
- Pliers or needle-nose pliers
- Safety glasses and gloves
Safety Precautions
Before you begin any chainsaw repair, it’s essential to take the following safety precautions:
- Wear safety glasses and gloves at all times.
- Disconnect the spark plug to prevent the chainsaw from starting accidentally.
- Allow the chainsaw to cool down before you begin working on it.

Step-by-Step Guide to Fixing a Chainsaw Chain
Now that you have the necessary tools and safety precautions in place, let’s dive into the step-by-step guide to fixing a chainsaw chain:
Step 1: Check the Chain Tension
The first step is to check the chain tension. A loose chain can slip off the guide bar or cause the chainsaw to bounce excessively. To check the chain tension, grab the chain with your gloved hands and pull it away from the guide bar. There should be about 1/2 to 3/4 of an inch of slack. If the chain is too loose or too tight, adjust it as follows:
- To tighten the chain: Use the chain tensioning tool or flathead screwdriver to turn the chain tensioning screw clockwise.
- To loosen the chain: Turn the chain tensioning screw counterclockwise.
Step 2: Inspect the Chain for Damage
Once the chain is properly tensioned, inspect it for any damage. Look for any missing or broken teeth, cracks, or other signs of damage. If you find any damaged links, you’ll need to replace them.
Step 3: Replace Damaged Links (Optional)
Replacing damaged chainsaw links is a relatively simple process. Here’s how to do it:
- Remove the damaged links: Use pliers or needle-nose pliers to remove the cotter pins that hold the damaged links in place. Then, pull the links off the chain.
- Install the new links: Insert the new links into the chain, aligning them with the existing drive links.
- Secure the new links: Insert new cotter pins through the holes in the links and spread the ends of the cotter pins apart to secure them.
Step 4: Sharpen the Chain
A dull chainsaw chain can make cutting difficult and inefficient. If your chainsaw chain is dull, you can sharpen it using a chain file and file guide. Here’s how to do it:
- Secure the chainsaw: Clamp the chainsaw in a vise or place it on a stable surface.
- Position the file: Insert the chain file into the file guide and position it at the first cutting link.
- Sharpen the chain: Hold the file at a 30-degree angle to the cutting link and push it forward in a smooth, even motion.
- Repeat process: Continue sharpening the remaining cutting links, following the natural angle of each link.
Step 5: Lubricate the Chain
Lubrication is essential for keeping your chainsaw chain running smoothly and preventing premature wear. Lubricate the chain regularly using a chainsaw lubricant. To do this:
- Apply the lubricant: Hold the can of lubricant 12-18 inches from the chain and spray it evenly over the entire length of the chain.
- Wipe off excess: Use a rag to wipe off any excess lubricant from the chain.
