Chainsaws make it easier and quicker to bring down trees and manage growth. Arborists, landscapers, gardeners and other such professionals use these tools regularly. The chainsaw chain is the most critical component of this tool, and it should always be in prime cutting condition.
Dull chains won’t cut wood effectively, and it takes more time to get the job done. They are also more likely to snap and damage the chainsaw, which is why professionals must keep their chains sharp. Check the condition of the teeth before every job to avoid problems later on. Here’s a comprehensive guide on how to sharpen a chainsaw:
Why Does My Chainsaw Chain Dull So Quickly?
A chainsaw chain will become dull after repeated use. Friction and heat can take a toll on the edge, reducing its cutting power. A chain should last for approximately five years if you use it frequently and longer under occasional use. Here are some reasons why it can grow dull quickly:
- Hitting Dirt – If the chainsaw blade hits the ground, that can dull it almost immediately, and they aren’t designed to handle stone or dirt. It is best to ensure the chainsaw never hits the ground while cutting.
- Dirty Tree – Some trees have stone fragments and metal pieces in them. They can easily damage a chain’s edge and cause problems, so you need to check the tree carefully before cutting.
- Bent Blade – A bent or malformed chainsaw blade can also cause damage. If the blade isn’t aligned properly, the cutting edge won’t meet the wood at the right angle, and that can cause it to become dull. Look down the blade to make sure it is perfectly straight before using it.
These are some of the most common reasons why chainsaw chains become dull quickly. Mastering the right technique will help you avoid the problem and keep the chains sharp for a longer duration.
Is It Worth Sharpening A Chainsaw?
Chainsaw chains can last between 5 and 10 years, depending on the quality of the product and frequency of use. They will remain efficient and useful for that duration if you sharpen the chains regularly and maintain them well. Sharpening has several advantages, including:
- Superior Performance – Sharp chains have excellent cutting power and can get through wood effortlessly. You won’t have to spend as much time on the job and will be able to work more productively.
- Benefit of Tools – Your chainsaw will last longer because it doesn’t have to exert much force to cut through wood with a sharp chain. If you use the tool regularly, it is vital to keep the chain in good condition.
- Expenses – Sharpened chainsaw chains last longer than dull chains, and they cut through wood effortlessly, which means they don’t experience as much friction or wear. You won’t need to replace the chain as often.
As you can see, it is worth the time and effort to sharpen these chains regularly. It may take a few practice runs to master the technique, but you will be able to sharpen the chain in around 15 minutes.
How Often Do You Need To Sharpen A Chainsaw?
You can sharpen it abound ten times before you need to replace it. The sharpening process removes some material from the edge so you can only do it a few times without compromising the chain’s structural integrity.
The sharpening frequency will vary based on the working conditions and the arborist’s technique. An inexperienced professional is more likely to hit the ground while cutting or forget to check the tree for metal, debris, and dirt. They will go through more chains than professionals.
As a general rule of thumb, arborists sharpen their chainsaw chains every after every 4 or 5 trees. Some sharpen them every time they need to refill the chainsaw’s fuel tank or wait twice as long.
There’s no fixed schedule recommended by manufacturers, so you just need to be vigilant. If your chainsaw chain isn’t performing as well as it used to, it may be time to sharpen it. Eventually, you will come up with your sharpening schedule based on experience to maintain consistent performance.
What Is The Best Way To Sharpen A Chainsaw?
Sharpening may seem intimidating, but it is a relatively simple process if you follow the steps correctly. However, it is essential to unplug the tool or empty the tank before working on the chain. Make sure you wear protective eyeglasses and gloves while handling the chain.
- Type of Chain and Angle Specifications – The chain manufacturer will provide sharpening angle specifications in the user manual. Different kinds of chains require different methods of sharpening, so consult the manual or manufacturer before working on the teeth.
- Check First – Check the waste from cutting to see if it is time to sharpen the chain. If your saw provides wood chips, it is still sufficiently sharp and doesn’t need any maintenance. If the saw produces fine wood dust, it is grinding the wood instead of cutting it. That’s the indication of a dull chain that requires sharpening immediately.
- Use the Right Tools – It is vital to use the right files for sharpening because the wrong ones can damage the chain permanently. You will need a round file, file guide, and flat file with a depth gauge. Don’t use a rattail file as it can damage the cutters.
- Inspect the Blade and Chain for Damage – If you see damage like cracked or broken cutters, bent or burned drive links, abrasive damage, severely blunt teeth, or loose rivets, address them before sharpening the chain. The tool won’t perform well if you have these issues regardless of how sharp the chain is.
- Check The Gauge – Always check the depth of gauge during the filing process to ensure you don’t take too much material away from the chain.
- Clean Before Sharpening – Always clean the blade and chain before sharpening. Remove all dust, grime, oil, and grease before working on the teeth to reduce the chances of damage.
Taking these precautions ensures you get the best performance from the chainsaw chains. This is the most effective approach to sharpening different kinds of chains.
What Is The Best Angle To Sharpen A Chainsaw Chain?
The angle used during sharpening will determine how sharp and efficient your chain is. Consult the manufacturer’s guidelines for the right angle for different kinds of products. Most experts recommend a 30° to 35° angle for optimal results. The file should be positioned at this angle from the bar horizontally. The vertical angle at the bottom should be at 90° to be most effective.
Always file away from your body instead of towards it. A file guide will make sure the teeth are filed to the right depth and shape. Check it regularly during the filing process to ensure you don’t take too much material away. It is also essential to count the strokes on each tooth so that you can maintain consistency. Every tooth will need the same number of strokes.
How Do You Sharpen A Chainsaw With An Electric Sharpener?
- Measure the pitch and gauge required for your specific chainsaw. These measurements are available on the manual or online.
- Position the electric chainsaw sharpener according to the specifications provided. Make sure the sharpener is on a stable surface to reduce shaking. Most experts place it on the ground.
- Install the sharpening stone according to the chain’s requirements and position it correctly.
- Set the swivel angle between 0° to 60° based on pitch and gauge calculations. You may need to go up to 80° for some chainsaw blades.
- Adjust the depth and angle before sharpening carefully. Make sure you don’t take too much material away from the teeth.
How To Sharpen A Chainsaw With A Grinder
- Use a sharp and new grinding stone for chainsaw chains.
- Calculate the pitch and depth requirements by consulting the chainsaw chain manual or box. Manufacturers will provide accurate numbers for it.
- Place the chainsaw on a stable surface to ensure it doesn’t shake during the grinding process. You want it to be steady to ensure there are no mistakes.
- Maintain the right angle and pass the grinder carefully over the edge. Keep track of the number of strokes and check the depth between passes.
How To Sharpen A Chainsaw With A Dremel
- Pick the right grinding wheel from your Dremel tool kit for the chainsaw chain type. The kit will also come with a guide to help you control the cutting depth.
- Place the grinding tip on the teeth and make sure it is parallel to the factory-ground angle.
- Apply sideways pressure and turn on the tool for grinding. You need to count until four for every tooth.
- The process is similar to using a hand file, so follow those steps to make sure the teeth are sharpened correctly.
Properly sharpened chainsaw chains deliver superior performance and last for a long time. They also help extend the chainsaw’s lifespan significantly which means you get a good return on investment.
