How To Sharpen A Chainsaw Chain

Are you tired of struggling with a dull chainsaw chain? Do you want to learn how to sharpen it yourself? Look no further! In this article, we'll guide you through the process step by step. First, let's start with understanding the anatomy of a chainsaw chain.

Understanding the Anatomy of a Chainsaw Chain

A chainsaw chain consists of three main parts – the cutters, the drive links, and the tie straps. The cutters are the sharp teeth that cut through wood. Drive links are the pieces that sit in the chainsaw's guide bar slot and engage with the sprocket, allowing the chain to move. Lastly, tie straps are the small, curved pieces of metal that connect the cutters and drive links. Understanding the anatomy of a chainsaw chain is crucial to properly sharpening it.

Choosing the Right Tools for Sharpening

When it comes to sharpening a chainsaw chain, using the right tools is key to achieving a sharp and effective edge. Here are the essential tools you will need:

1. Round File: This is one of the most essential tools for sharpening the chainsaw chain. The round file comes in different sizes, so it's essential to use the right size that matches the chain's pitch. Consult your chainsaw manual to determine the chain's pitch.
2. File Guide: A File guide is an essential tool that helps to maintain the right angle while sharpening the chain. It ensures the sharpening angle is consistent throughout the process and that each tooth gets the same treatment.
3. Depth Gauge: A depth gauge, also known as a Chainsaw Raker, is another crucial tool to help maintain the right depth between the teeth. It determines the depth of the cut of each tooth and helps keep the chain's performance within spec.
4. Vise or Clamp: Clamping or mounting your chainsaw before sharpening the chain is an essential safety precaution. It ensures that the chainsaw is secure and stable during the sharpening process, helping to maintain consistency throughout.
5. Cleaner: It is also important to have a cleaner on hand to remove any dirt, sawdust, or debris from the chain. A clean chain will sharpen better and last longer.

It's important to keep your tools in good condition, and remember to replace your file guide and depth gauge when they become worn or damaged. Investing in high-quality sharpener tools might cost more upfront, but it ensures longer-lasting, sharper chains and saves money in the long run.

Remember to follow the manufacturer's instructions on the tools you purchase. When sharpening the chainsaw chain, it's important to maintain the same angle and depth throughout the process. The right tools combined with consistent sharpening can maintain chain sharpness, extend the chainsaw's life, and improve your cutting performance.

Preparing the Chainsaw Chain for Sharpening

Before you can begin sharpening your chainsaw chain, you need to prepare it properly. Here are the steps you should follow:

1. Remove the chain from the chainsaw:

   The first step is to remove the chain from the chainsaw. This will give you better access to the chain, making it easier to clean and sharpen. Make sure the chain is completely cool before handling it.

2. Clean the chain:

   Using a wire brush or other tool, remove any debris from the chain. This can be dirt, sawdust, or any other material that has accumulated on the chain during use. Cleaning the chain will help you see the teeth more clearly when you move on to sharpening.

3. Inspect the chain:

   Before you start sharpening, it's important to inspect the chain to ensure that it is in good condition. Look for any damaged or broken teeth, and replace them if necessary. You should also check the tension of the chain, and adjust it if needed. A loose chain can be dangerous to use.

4. Measure the chain:

   You need to know the correct file size for your chainsaw chain. This can be found in the chainsaw owner's manual or on the chain itself. Make sure you have the correct file size before you start sharpening.

By following these steps to prepare your chainsaw chain for sharpening, you'll be ready to move on to the next stage of the sharpening process with confidence.

Sharpening Techniques for Different Types of Chains

Different chainsaw chains require different types of sharpening techniques. Each chain has unique features, such as the size and shape of its teeth, the angle of the cutting edge, and the pitch of the chain. Here are some sharpening techniques that are specific to different types of chains:

1. Standard Chains

   The most common type of chainsaw chain is the standard chain. Standard chains are often used for general-purpose cutting and are characterized by their evenly spaced teeth, which are typically between ¼ and 3/8 inches in size. To sharpen a standard chain, you can use a round file that matches the size of the teeth. Make sure to file at a 25-degree angle and remove an equal amount of metal from each tooth to maintain even cutting performance.

2. Low-profile Chains

   Low-profile chains are designed for use with lightweight chainsaws and are typically used for tasks such as pruning and limbing. These chains have teeth that are closer together than those on standard chains, with a depth gauge that is lower than the cutting teeth. To sharpen a low-profile chain, you need to use a flat file to sharpen the top plate of each tooth and a depth gauge tool to file the depth gauges to the correct height.

3. Ripping Chains

   Ripping chains are used for cutting wood along the grain, rather than against it. They have fewer teeth than standard chains and those teeth are designed to cut large chips out of the wood. To sharpen a ripping chain, use a special ripping chain file that has a specific tooth shape that matches the chain. It's also important to file each tooth at a 10-degree angle and to remove an equal amount of metal from each tooth to maintain balance.

4. Carving Chains

   Carving chains have teeth that are shaped like small hooks that allow for intricate, detailed cuts. To sharpen a carving chain, use a diamond file and sharpen each tooth individually by hand, making sure to maintain the angle and the hook shape.

5. Safety Tip

   Before sharpening any type of chainsaw chain, make sure to wear protective gloves and eyewear to prevent injury from the sharp chain, and to secure the chainsaw to prevent it from moving or starting accidentally.

By knowing how to sharpen different types of chainsaw chains, you can ensure that your chainsaw will always be ready for any cutting task you have at hand. Remember to maintain your chainsaw regularly, including sharpening the chain, to ensure its optimal performance and longevity.

Testing and Adjusting the Chain Tension

After sharpening the chainsaw chain, it is important to check the chain tension and adjust it if necessary. The chain's tension should be just right, neither too tight nor too loose. An over-tight or too loose chain can affect the chainsaw's performance and pose a safety hazard. Here is how you test and adjust your chain tension.

1. Testing Chain Tension:

The first step is to check the chain's tension. To do this, turn off the chainsaw and place it on a flat surface. Loosen the bar nut using a wrench to allow the bar to move. Next, lift the chain to check the tension. You can do this at the center of the bar's length or at the bar's tip.

The chain tension is perfect if the chain can be lifted half-way off the bar's tip or center and can snap back into place. The correct tension ensures the chain is not too tight that it binds or too loose that it slips off.

2. Loosen the chain:

In case the chain is too tight, locate the chain tension screw, which is found near the chainsaw's bar. Using a screwdriver, turn the screw counterclockwise to loosen the chain slightly. After loosening the chain, use your hand to check whether the chain can be lifted and returns to its place.

3. Tighten the chain:

If the chain tension is too loose, you will need to tighten it. To do this, locate the tension screw and use your screwdriver to turn it clockwise. Tighten it until you achieve the correct chain tension. After tightening the chain, use your hand to check whether the chain can be lifted to the center of the bar and snaps back to its place.

4. Recheck the chain tension:

After tightening or loosening the chain, ensure that it's tightened accurately by checking the chain tension using the method outlined in step 1.

5. Reassemble the Chainsaw:

After you have confirmed the chain tension is just right, reassemble your chainsaw. Tighten the bar nuts but not too tight. Close up the sprocket cover and tighten the nuts as the manufacturer recommends.

Testing and adjusting chain tension helps ensure the chainsaw functions correctly and is secure. Remember, a loose chain can pop off the bar, while a too-tight chain can interfere with the saw's performance. If you're unsure of how to adjust the chain tension, consult your chainsaw owner's manual or bring it to a professional chainsaw technician.

Maintaining a Sharp Chainsaw Chain for Optimal Performance

Sharpening your chainsaw chain is a great start to keeping your chainsaw in good condition. However, you have to do more if you want your chainsaw to function optimally and last longer. Below are some tips on how to maintain a sharp chainsaw chain:

1. Oil the Chain

   To reduce friction, the chain needs lubrication. Make sure you oil the chain before you start cutting. You can either use a manual oiler or an automatic oiler built into your chainsaw. Always check the oil level to ensure you have enough oil, and refill as needed. If you don't have enough oil, the chain will quickly deteriorate, lose sharpness, and wear out faster.

2. Clean the Chain

   After a cutting session, there will be debris and sawdust lodged in the chain. Use a handheld blower or compressed air to clean the chain and other parts of the saw. You can also use a cleaning solution, which you can apply using a brush to remove stubborn dirt and oil buildup. When the chain is clean, drying it is essential before storing it to prevent rust.

3. Tighten the Chain

   A loose chain is not only dangerous but will also affect the cutting performance of your chainsaw. Make sure you check the chain tension before starting any cutting sessions. Tighten it appropriately, but do not make it too tight. A hand-tight tension is usually enough.

4. Replace Worn Out Parts

   If the chain is too damaged, you may need to replace it with a new one. It's also essential to check and replace other parts of the saw that may have worn out or damaged, such as the bar, sprocket, and clutch.

5. Store the Chainsaw Properly

   When you've finished using your chainsaw, always store it properly. Use a chain guard to cover the chain, and keep it in a cool, dry place to prevent rust. You can also use a protective case for additional protection. When storing the chainsaw, ensure that it is away from direct sunlight, rain, and other harsh weather elements.

Maintaining your chainsaw is essential to ensure it functions optimally, and you avoid common hazards. As a general rule, always follow the manufacturer's instructions when maintaining your chainsaw, and keep it sharp and in good condition to make your cutting jobs faster and efficient. Remember to keep it out of the reach of children and pets at all times.
