How Do I Take Care of My Chainsaw and Fix Common Problems?

When I first started selling cordless chainsaws¹ to international buyers, I noticed one thing: even experienced users often run into problems because of small mistakes—especially with lubrication, tension, and cleaning. And for B2B clients, those small issues can lead to returns, complaints, and unhappy customers. That’s why I always say: selling a good chainsaw isn’t enough—we must teach our buyers how to take care of it.

Regular maintenance, correct usage habits, and simple troubleshooting steps can greatly extend the life of your chainsaw and prevent major breakdowns.

Chainsaws may look strong, but they’re sensitive machines. The more we understand their care routine, the less time we spend fixing them—and the more trust we build with customers who rely on us.

How often should I lubricate my chainsaw?

Every chainsaw needs chain oil². It sounds basic, but many users overlook it or use the wrong type. That’s a recipe for trouble. Whether you’re cutting dry wood or trimming branches³, friction can quickly wear out the chain if it’s not oiled properly.

Lubricate your chainsaw every time you refill the battery or fuel—and always check the oil level before use.

Lubrication isn’t just a maintenance step. It’s a safety requirement.

In my experience working with importers and professional users across Europe and Latin America, poor chain lubrication is one of the top three causes of warranty claims. When the chain moves at high speed without oil, the bar heats up, metal expands, and the entire cutting system suffers.

Here’s what I recommend:

• Use proper bar and chain oil—don’t replace it with motor oil or other substitutes.
• Before each use, check that the oil reservoir is full.
• After a few cuts, hold the chainsaw over a light-colored surface. Rev the motor slightly and watch for oil spatter. If there’s no trace, the oiler may be clogged.
• Clean the oil outlet port regularly, especially if you’re working in dusty environments.
• Don’t assume a new chainsaw is perfectly tuned. Some models need the oil flow adjusted manually via a screw under the housing.

One of my Italian clients once returned a shipment of 200 units because they thought the chainsaws had "faulty chains." In reality, they were using them without oil. We added a sticker reminder on all future shipments: “Lubricate before every use.”

What not to do when operating a chainsaw?

Chainsaws aren’t dangerous by design—they become dangerous when used incorrectly. And many accidents or breakdowns start with small habits that seem harmless at first.

Avoid forcing the saw, using dull chains, or operating without PPE; these mistakes damage the tool and put users at risk.

Chainsaws are machines of precision. Even a minor mistake can damage the bar, throw the chain off, or stress the motor.

Let’s break down a few common “don’ts” that I always mention during product training for our B2B clients:

1. Don’t force the cut.

If your chainsaw is well-lubricated and sharp, it should cut through wood like a hot knife through butter. If you’re pushing hard, something’s wrong—most likely a dull chain, loose chain tension, or low battery.

2. Don’t run it without load for too long.

Running the chain in the air to “test” it sounds innocent, but it builds heat and wears down the bar tip unnecessarily.

3. Don’t skip chain sharpening.

Even a premium chainsaw becomes useless if the chain is dull. Teach your customers how to recognize dull teeth and sharpen them using a round file or electric sharpener.

4. Don’t ignore personal safety gear.

Many B2B buyers ask me for “safety kits” to resell along with tools. That’s smart. Safety glasses, gloves, and ear protection should always go with every cordless chainsaw.

5. Don’t store the chainsaw dirty.

After every job, clean off sawdust and resin. These clog the sprocket and oiling system over time.

One of our longtime buyers in Turkey added a “What Not To Do” card in each package after a batch of customer damage complaints. The card reduced their return rate by 27% in three months.

What are the most common chainsaw problems—and how can I fix them?

Chainsaws don’t usually break without warning. Most of the time, the signs are there: slow cutting, overheating, odd noises. Spotting them early can save time, money, and relationships with buyers.

Common problems include chain slippage, poor cutting performance, motor overheating, or oil leakage—most are easy to fix with regular checks and cleaning.

Let’s go deeper into each one.

1. Chain keeps slipping off

This is one of the most reported problems. Usually, it comes from improper tension. A loose chain can jump off the bar and cause serious damage—or injury.

Fix: Unplug the battery. Loosen the bar nuts, then adjust the tension screw until the chain lifts slightly when pulled but snaps back into place. Tighten the nuts back. Check it again after the first few cuts.

2. Chainsaw doesn’t cut properly

A sharp chain should dig in with minimal pressure. If it doesn’t:

• Sharpen the chain
• Check the bar groove for clogs
• Inspect the chain direction (yes, some users install it backwards)

3. Chainsaw overheats

Overheating often points to a dull chain, dry bar, or clogged air vents in brushless models. Battery-powered models like our 21V chainsaws need good airflow to avoid performance loss.

Fix: Let the motor rest. Check for dust buildup around vents. Clean with a soft brush or compressed air.

4. Oil leaks during storage

This one scares many first-time buyers. But here’s the truth: a small amount of leakage is normal due to gravity. However, excess oil may signal a cracked tank or faulty cap seal.

Fix: Store the chainsaw horizontally with the oil cap facing up. Wipe the tank and seal. If it keeps leaking, contact the supplier for a replacement gasket.

In our after-sales training materials, I always include a troubleshooting table. Distributors love it. It reduces unnecessary complaints and builds trust.

Conclusion

Chainsaws aren’t just tools—they’re precision machines that need regular care. Whether you’re a homeowner trimming a backyard tree or a wholesaler managing large shipments, knowing how to maintain and troubleshoot a chainsaw makes a real difference.

I’ve worked with buyers from Italy to Brazil who told me the same thing: the best chainsaws are not just the ones that work well, but the ones that come with clear instructions and responsive support.

That’s what we aim to provide at YOUWE. Efficient cuts, dependable machines, and long-term partnerships.

🔧 Frequently Asked Questions (FAQ) About Chainsaw Maintenance

1. How often should I oil my chainsaw?

You should check and refill the chain oil every time you recharge the battery or refuel the tank. Chains need constant lubrication to avoid overheating and wear.

---

2. Why is my chainsaw chain always falling off?

Chain slippage usually means the tension is too loose. Check the tension before each use and adjust it using the tension screw near the bar.

3. What kind of oil should I use for my chainsaw?

Always use bar and chain oil. Avoid using used motor oil or other substitutes—they don’t provide proper lubrication and can clog the system.

4. How can I tell if my chainsaw chain is dull?

If you need to push the saw into the wood, or you see fine dust instead of wood chips, your chain is dull and needs sharpening.

5. Is it normal for my chainsaw to leak oil when not in use?

A little leakage is normal. But if oil is pooling under your chainsaw, check the tank seal and store it horizontally with the oil cap facing up.

6. Can I use my chainsaw without safety gear?

No, you should always wear PPE like gloves, goggles, and ear protection. Chainsaws can kick back or throw debris during use.

7. Why is my chainsaw overheating after just a few minutes?

It could be due to a dull chain, lack of oil, or clogged air vents. Let the tool rest and clean the vents before using again.

8. What are the signs of poor chain lubrication?

Signs include slow cutting, a smoking bar, or dry noise while running. Always check oil flow by revving over a light surface.

9. Can I test my chainsaw without cutting anything?

Avoid running your chainsaw without load for too long. It can overheat the bar tip and wear down components unnecessarily.

10. How should I clean my chainsaw after use?

Use a brush to remove sawdust, wipe the bar and chain, and clean the oil port regularly. Don’t store it dirty—it shortens the tool’s life.
