Why Is My Chainsaw Not Cutting

Chainsaws are powerful and versatile tools used for various tasks, from pruning trees to cutting firewood. 

However, when a chainsaw is not cutting properly, it can be frustrating and significantly slow down your work. 

A chainsaw may not be cut due to several reasons, such as a dull chain, improper chain tension, a faulty chain brake, clogged air or fuel filters, a blocked bar groove, a damaged drive sprocket, worn out clutch, or low chain lubricant. 

This article will explore the various causes of  Why Is My Chainsaw Not Cutting and provide tips for fixing the problem.

Why Is My Chainsaw Not Cutting – Possible Causes

A chainsaw not cutting can be a frustrating experience for any user. However, before you start looking for a solution, it is important to identify the possible causes of the problem. Here are some possible reasons for a chainsaw not cutting:

A. Dull Chain: 

A dull chain is one of the most common causes of a chainsaw not cutting. A dull chain can result from regular use, hitting the dirt, or hitting rocks. A dull chain needs to be sharpened or replaced.

B. Improper Chain Tension:

 If the chain is too tight or too loose, it can cause the chainsaw not to cut properly. You need to ensure the chain tension is correct to get the best performance from your chainsaw.

C. Faulty Chain Brake:

 A faulty chain brake can prevent the chain from rotating and result in the chainsaw not cutting. You should ensure the chain brake is not engaged when cutting.

D. Clogged Air Filter:

 A clogged air filter can prevent air from flowing into the engine, causing the chainsaw not to start or cut properly. You should clean or replace the air filter regularly.

E. Clogged Fuel Filter:

 A clogged fuel filter can prevent fuel from reaching the carburetor, resulting in the chainsaw not starting or cutting properly. You should clean or replace the fuel filter regularly.

F. Blocked Bar Groove:

 A blocked bar groove can cause the chain to stick or jump off the bar, resulting in the chainsaw not cutting properly. You should clean the bar groove regularly to prevent this from happening.

G. Damaged Drive Sprocket: 

A damaged drive sprocket can cause the chain to slip or not rotate properly, resulting in the chainsaw not cutting properly. You should replace the drive sprocket if it is damaged.

H. Worn Out Clutch:

 A worn-out clutch can cause the chainsaw not to start or cut properly. You should replace the clutch if it is worn out.

I. Low Chain Lubricant: 

If the chainsaw is not lubricated properly, it can cause the chain not to rotate properly, resulting in the chainsaw not cutting properly. You should ensure that there is enough chain lubricant in the chainsaw.

By identifying the possible causes of a chainsaw not cutting, you can take the necessary steps to troubleshoot and resolve the problem. 

How To Fix A Chainsaw That’s Not Cutting

If you’ve identified one or more of the possible causes for your chainsaw not cutting, here are some steps you can take to fix the problem:

1. Sharpen the Chain:

 If your chain is dull, it won’t cut effectively. You can sharpen it yourself using a chainsaw file or take it to a professional for sharpening.

2.  Adjust Chain Tension:

 If the chain tension is too loose or tight, it can affect the cutting performance. Check the manufacturer’s instructions on how to adjust the tension properly.

3. Check and Fix the Chain Brake:

 A faulty chain brake can cause the chainsaw to stop cutting. Inspect the brake and replace any broken or worn-out parts.

4. Clean or Replace the Air Filter: 

A clogged air filter can restrict airflow and cause the engine to run poorly. Clean or replace the filter according to the manufacturer’s instructions.

5. Clean or Replace the Fuel Filter: 

A clogged fuel filter can prevent fuel from reaching the engine. Clean or replace the filter according to the manufacturer’s instructions.

6. Clean the Bar Groove: 

Dirt and debris can accumulate in the bar groove, causing the chain to slow down or stop. Clean the groove regularly to ensure smooth operation.

7. Replace the Drive Sprocket:

 If the drive sprocket is damaged, it can cause the chain to slip or stop. Replace the sprocket with a new one that matches the chainsaw model.

8. Replace the Clutch:

 A worn-out clutch can cause the chain to slip or not engage. Replace the clutch with a new one that matches the chainsaw model.

9. Refill Chain Oil:

 If the chainsaw is not getting enough lubrication, it can cause the chain to heat up and stop cutting. Refill the chain oil reservoir according to the manufacturer’s instructions.

By following these steps, you can fix your chainsaw and get it cutting effectively again.

How Does a Chainsaw Chain Become Dull?

A chainsaw chain becomes dull over time as it comes into contact with wood, soil, rocks, and other materials. Each time the chain cuts, it is subjected to wear and tear, which can cause the chain to become dull. 

Other factors contributing to a dull chain include improper use or maintenance, such as running the chain against hard surfaces, using a chain with the wrong tooth configuration, or not keeping the chain properly lubricated. 

A dull chain can lead to a less efficient cutting process, causing frustration and potentially dangerous situations.

Tips for Sharpening Your Chainsaw Chain

Sure, here are some tips for sharpening your chainsaw chain:

• Use a filing guide: A filing guide ensures that you file the cutters at the correct angles and depth, which is important for maintaining the chain’s cutting efficiency.

• Use the correct file size: Chainsaw chains come in different sizes, so make sure you use the correct size file. Using the wrong size file can damage the chain and make it less effective.

• Wear protective gear: Always wear protective gear when sharpening your chainsaw chain, including gloves and eye and ear protection. The sharpening process creates a lot of debris, so protecting your eyes and ears is important.

• Start with the cutters: Begin by sharpening the teeth that do the cutting. Use a round file to file the top plate and then the side plate of each cutter.

• Check the depth gauge: The depth gauge controls the depth of each cut made by the cutter. Check and file the depth gauge to maintain the correct cutting depth.

• File in one direction: Always file in one direction, away from your body. This helps maintain consistency and prevents damage to the chain.

• Refrain from over-filing: Over-filing the cutters can cause them to wear down faster, so file each cutter as much as necessary to maintain its sharpness.

Following these tips, you can effectively sharpen your chainsaw chain and keep it cutting smoothly and efficiently.

Conclusion

In conclusion, there can be various reasons why a chainsaw is not cutting as it should. From a dull chain to low chain lubrication, every aspect plays a significant role in the proper functioning of a chainsaw. 

By understanding the potential causes and following the appropriate solutions, you can ensure that your chainsaw is always in good condition and performing at its best. Regular maintenance and proper use can extend the lifespan of your chainsaw, saving you both time and money in the long run.
