Everything about Chainsaw Bar Life Expectancy and Maintenance

The chainsaw, primarily used in assisting childbirth, is now used to cut down even trees! As technology advanced, it has evolved into something more than it was before. 

And an integral part of that chainsaw is its bar. Without it, the chainsaw would become obsolete. So, it just makes sense that you'd want to know the chainsaw bar life expectancy.

Chainsaw bars don't have any pre-defined duration or length as lifespan. Their longevity depends on several factors and mechanisms, including a proper maintenance approach. Yet, with regular use & care, a chainsaw bar can last for over five years. 

But how do you determine the condition of your chainsaw bar? It's a topic that needs further discussion. Let's go!

Life Expectancy of Chainsaw Bar

Usually, you can enjoy hundreds of hours of use with a solo chain of a chainsaw. Most chainsaw chains use steel blades frame to constitute their cutter. Your chainsaw's life expectancy will depend on your use. If you take proper care and perform regular maintenance, your chainsaw will work smoothly for a long time.

However, nothing lasts forever, not even the cold November rain! The more you work your cutting machine and the heavier the load upon it, the sooner it'll wear out.

How to Maintain a Chainsaw Bar with Proper Care?

Tools like chainsaws need care and maintenance, without which they can malfunction and turn into something hazardous for you. Here are a few tips to help you maintain and care for the power tool.

How to Maintain a Chainsaw Bar with Proper Care
  • Keep your chain edge in sharp condition. A blunt chainsaw can drone back and injure you.
  • Keep the bar and chain lubricated. It's a good idea to keep extra oil close at hand and always keep the topmost layer greased. If the bar and chain aren't greased up properly, you'll have to face great difficulties in all your cutting projects.
  • Adjust your chain tension according to the projects.
  • Perform a regular check-up on the air filter. If you regularly clean up the air filter, it'll help the machine last longer. It's a good idea to use moisturizer oil to prevent any contact with air from preventing air damages.
  • Clean up your machine after every use. Make sure to dry it off properly so that no watery chips stay behind. 

There should be no problems if your maintenance is up to par and done regularly.

Sharpening the Chainsaw Bar

There's a huge difference between sharpening and replacing. When the teeth on your chain are worn down, you'll need to sharpen them.

Sharpening the Chainsaw Bar

While you may expect the manufacturer's input on this matter, there are none. However, there are some factors that you can focus on that will determine the number of times you can sharpen the chain. Here are a few pointers.

  • Extent of wear or damage to your chainsaw
  • Quantity of removing the metal after sharpening each time

When the teeth are worn down, you need to sharpen them. So, every time you sharpen the chain's teeth, they lose a certain amount of internal metal, on which the number of times you can sharpen your chain depends.

However, there's a rough estimate that you can sharpen a chainsaw bar from three to five times over its lifetime.

How to Tell If Chainsaw Bar Is Bad?

Having a powerful but blunt tool can cause severe mishaps and losses to you and your favorite machine. That's why you need to be able to tell if your chainsaw bar is too worn down to handle any of your projects.

Chainsaw Bar Is Bad

Here are a few telltale signs to help you understand when it's time to bid farewell to your chainsaw.

  • Chain is readily removed from the bar
  • Missing teeth
  • Rust on the surface
  • Lessened cutting efficiency
  • A shaky performance with smoke coming out of the machine
  • Bar seems bent
  • Wider bar sides
  • Damage nose sprocket
  • Chipped chainsaw chain

There are also some tests you can run to test the health of your chainsaw bar.

Check If It's Bent

A chainsaw with a bent bar will pull to one side or the other. If your chainsaw can't cut straight all of the time, it's considered to be bent. Remove the bar from the chainsaw and lay it down on a flat surface. That way, you can check whether if it's bent or flat.

Check If It's Too Low

You can check the bar's height with a gauge tool. A distinct mark on the gauge tool indicates if your bar is too low or okay to use. If the bar exceeds that line, you'll know that the bar's too low.

Check the Bar Width

Your bar chain can jump out of the bar if it's too wide. After checking to see if your chain is tensioned correctly, put on a pair of gloves. Hold the chain tightly and jerk it side by side. If you see the chain shaking a lot, then the bar is bent.

Check If There're Pinches

Any grime or pinches on your chainsaw bar can create extra friction that can damage your work and the machine. If the pinches don't go away no matter what you do, it's time to get a replacement.

When to Replace Chainsaw Bar?

Chainsaw bars don't last forever, and they will have exceeded their average life expectancy at one point. Here are a few ways to judge when your chainsaw bar might need replacement.

Replace Chainsaw Bar
  • If your chain doesn't pull itself into the wood, it becomes pretty tricky to cut the wood. Then you'll have to put extra pressure on the chain to get the job done. But it'll leave behind crooked wood parts, which shows that you need to replace your chainsaw bar.
  • The chainsaw cutter has some lines imprinted onto them to indicate its sharpness. If your cutter has exceeded any of those safety lines, it's time you get a new chainsaw bar.
  • If your chain has broken, impaired, cracker, or chipped teeth, it's time you get a replacement.
  • If your chainsaw has a rusty chain, then you are in danger of causing yourself an accident. Therefore, you need to replace the rusty one as soon as possible.

Final Words

As a homeowner, if you use a chainsaw frequently, you must be aware of the importance of this powerful tool.

So before getting into woodcutting, make sure that you have a well-sharpened & properly lubricated bar and chain. That will assist you for a smooth operation associated with a minimal jerk and help increase chainsaw bar life expectancy.
