Troubleshooting Chainsaw Cutting Problems [Like a Pro Tips]

Ever tried to rev up your chainsaw, only to find it’s just not cutting the way it should? 

The culprit is often a dull cutting chain. A worn-out chain can turn simple tasks into frustrating ordeals, and if it’s too loose or too tight, you’re in for a rough ride.

Add in issues like clogged filters and old fuel, and it’s clear why your trusty tool might not be performing its best.

Let’s dive deep into the world of chainsaws and troubleshoot these common cutting problems, ensuring your saw is always sharp, powerful, and ready for action.

Common Chainsaw Cutting Issues and Their Solutions


we will explore some of the problems that can affect chainsaw-cutting performance and how to address them.

Dull Chain

It would help if you sharpened the chain using a chainsaw file or sharpener to fix this problem. If the chain is severely damaged, it may need to be replaced.

Chain Tension

Another common chainsaw-cutting problem is improper chain tension. If the chain is too loose, it can derail and become damaged. If the chain is too tight, it can cause excessive wear on the chain and bar and make cutting more difficult.

To check the chain tension, turn off the chainsaw and use a flat-head screwdriver to adjust the tension screw. The correct tension should allow the chain to move freely but not sag from the bar.

Cutting Bar Issues

The cutting bar is an essential component of a chainsaw, and problems with the bar can affect the cutting performance. Common bar issues include warping, wear, and damage.

To check the bar, remove the chain and inspect the bar for any signs of damage or wear. If the bar is warped or damaged, it may need to be replaced.

Chain Lubrication

Proper lubrication is crucial for chainsaw-cutting performance. If the chain is not lubricated correctly, it can overheat and become damaged. Signs of insufficient lubrication include smoking and excessive wear on the chain and bar.

To fix this problem, check and refill the oil reservoir if necessary. Also, make sure the oil ports on the bar are clear and free from debris.

Air Filter

The air filter is another critical component of a chainsaw, and a dirty air filter can affect cutting performance. A dirty air filter can cause the engine to run too lean, resulting in poor cutting performance, reduced power, and engine damage.

To fix this problem, remove the air filter and clean it with soap and water or replace it with a new one.

Fuel Issues

Fuel issues can also affect chainsaw-cutting performance. Old or stale fuel can cause the engine to run poorly, resulting in poor cutting performance. Drain the old fuel from the chainsaw and replace it with fresh fuel to fix this problem. Also, ensure the fuel mixture is correct, and the fuel filter is clean.

why is my chainsaw struggling to cut?


When basic solutions don’t rectify the problem, it’s time to delve deeper. Here, we’ll address more intricate issues that might have you pondering, why is my chainsaw struggling to cut?

1. Chainsaw Only Burning Wood

If you notice your chainsaw not cutting just burning wood, it’s a significant indication of a dull chain or an issue with the chain’s angle against the wood.

Caution: Continuing to use a chainsaw that’s burning the wood can damage both the wood and the chainsaw. It can also pose safety hazards.

2. Chainsaw Not Cutting After Sharpening

It’s perplexing when your chainsaw isn’t cutting well even after a recent sharpening. This could be due to improper sharpening techniques, wrong file size, or the incorrect tension of the newly sharpened chain.

Always ensure that you use the correct file size for sharpening and that the chain’s teeth angles are consistent.

3. Chainsaw Stops Cutting Halfway Through

If your chainsaw stops cutting halfway through, this could be linked to problems with the clutch pads or overheating issues. Overheating can stem from a lack of lubrication or a faulty cooling system.

Suggestion: Ensure the chainsaw’s oiling mechanism is functioning correctly and the vents aren’t blocked.

4. Chainsaw Only Cuts at Tip

When a chainsaw only cuts at the tip, it could be due to wear and tear at specific points of the guide bar or an issue with the chain’s alignment on the bar groove.

Note: Rotate your guide bar regularly to ensure even wear and extend its lifespan.

5. New Chain But Chainsaw Won’t Cut

The baffling scenario of a new chain that a chainsaw won’t cut can be attributed to the chain’s installation. Perhaps the chain is backward, or there’s an incorrect tension.

Always double-check the chain’s orientation using the user manual and ensure the tension screw is adjusted properly after installing a new chain.

How to Troubleshoot Chainsaw Cutting Problems?


Keeping your chainsaw in optimal condition isn’t just about ensuring smooth cuts; it’s a matter of safety. Proper maintenance can prevent many of the common issues that lead users to question, why is my chainsaw not cutting?

1. Regular Checks

Consistently inspect the chainsaw blade, guide bar, and clutch cover for any signs of wear or damage. Addressing minor issues promptly can prevent them from escalating into major concerns.

Always disconnect the chainsaw from the power source (or remove the spark plug for gas-powered chainsaws) before performing any checks or maintenance.

2. Chain Tension

Maintain the right chain tension. Too tight, and you risk excessive wear; too loose, and the chain might come off the guide bar. If you’re uncertain about the incorrect tension, consult your chainsaw’s user manual or seek expert advice.

After adjusting the tension, always check the chainsaw’s operation in a safe environment before engaging in prolonged cutting.

3. Sharpening

A dull chain not only makes cutting inefficient but also poses a safety risk. Regularly sharpen the chain to ensure clean cuts and reduce the chances of kickback.

If you’re unfamiliar with the sharpening process or have experienced issues like chainsaw not cutting after sharpening, consider attending a workshop or watching instructional videos to master the technique.

4. Lubrication and Cleaning

Ensuring your chainsaw is well-lubricated and free from debris is crucial. This will prevent situations where the chainsaw isn’t cutting well due to friction or obstructions in the bar groove.

Use the recommended oil for your chainsaw model and clean the guide bar and chain regularly to remove any wood residue or dirt.

5. Electric Chainsaws:

For those using electric chainsaws, remember to check the battery’s health and the integrity of electrical connections. Avoiding moisture exposure and ensuring proper storage can prolong the life of electric chainsaws and prevent scenarios where you wonder, why is my electric chainsaw not cutting?

Never immerse an electric chainsaw in water or use it in wet conditions. This poses a significant electrocution risk.

Benefits of Troubleshooting Chainsaw Cutting Problems


The significant impacts of troubleshooting chainsaw cutting problems are:

Improved Performance

When chainsaw-cutting problems are identified and resolved, the chainsaw can operate more efficiently and effectively. Cutting tasks can be completed faster and with less effort, improving performance and productivity.

Increased safety

Chainsaws can be dangerous tools if not used properly, and troubleshooting chainsaw-cutting problems can help identify and address safety issues. Proper maintenance and repair can help prevent accidents and injuries, improving safety for the user and others nearby.

Cost Savings

Regular troubleshooting and maintenance can extend the life of a chainsaw and prevent the need for costly repairs or replacements. This can result in significant cost savings over time, reduced downtime, and increased productivity.

Environmental Benefits

Properly functioning chainsaws can reduce the amount of fuel and oil consumed and the number of emissions produced. This can positively impact the environment and help reduce the user’s carbon footprint.

Troubleshooting chainsaw-cutting problems can have various positive impacts, including improved performance, increased safety, cost savings, and environmental benefits. So you must regularly inspect and maintain chainsaws to ensure safe and effective operation.
