Chainsaw Troubleshooting Guide

Chainsaw is not starting

Check the Spark Plug

Check to see if there is a flaw in the spark plug. If the porcelain is broken, the electrode is harmed, or has a strong carbon build-up, you should break it and find out. You can replace the spark plug if one of these is the scenario.

Check the Carburetor

You should check if the carburetor is clogged. A clogged carburetor can be affected by leaving fuel in the chainsaw for a long period of time. This will stop the engine from running.

If the cleaning does not work, you can clean the carburetor with a can of carburetor cleaner or replace the part.

Test the Coil of Ignition

Due to a weak ignition coil, another explanation why the engine fails to start is. When the motor is on, the ignition coil transmits voltage to the spark plug. Until replacing the ignition coil, ensure that the spark plug is operating correctly.

For this chainsaw troubleshooting method, you should use an ignition coil tester.

Chainsaw Starts But Then Stalls

Check the Spark Arrestor

You can try out the spark arrestor that stops the engine from producing sparks to resolve this issue. After a long duration of operating the chainsaw, soot will clog the spark arrestor. The chainsaw can as a result, run rough or stall.

With a wire brush, remove and clean the spark arrestor or repair it if necessary.

Check the Air Filter

The air filter may be dirty or clogged. This leads it to have too much gasoline and less air in the engine. The engine would then stall.

To figure out if it’s clogged, check out the air filter and clean it. Otherwise, replace a new one with this filter.

Chainsaw is Running Rough

Check the Foam Filter

Try checking out the foam filter if your chainsaw is running hard. It’s dusty or clogged in the majority of situations. The approach to this challenge is simple. You need a foam filter replacement.

Check the Fuel Filter

A clogged fuel filter is another cause of your chainsaw running hard. A clogged fuel filter can be triggered by leaving old fuel in the chainsaw.

Any fuel ingredients evaporate and leave behind a material that is thicker and stickier. This clogs up the fuel filter, and the engine runs rough as a result.

When replacing the gasoline filter, make sure to remove and refill the old fuel with a fresh batch.

Chainsaw Chain is Not Turning

Check the Clutch

You’ll want to look at the clutch to fix this issue. To rotate the chain, the clutch pads activate the clutch drum. If the clutch pads are burned out the motor will still run, but the clutch drum will not be activated and the chain will not rotate.

The chain can not spin if the stop lever is engaged. So disengage the lever from the stop. Adjust the entire clutch assembly if you’ve worn out the clutch pads.

Check the Clutch Band Drum Break

The clutch band drum brake that activates the clutch drum to spin the chain may be another cause for the chain not spinning. The engine will run if the clutch band is worn out but the clutch band won’t trigger the clutch drum.

The chain would not switch, as a result. Replace the clutch if it’s worn out.

Chainsaw Won’t Cut

Replace or Sharpen the Chain

If you do not cut your chainsaw, it is possibly rusty and needs to be replaced or sharpened.

If a chain is slow, the clutch, engine, and many other parts cause needless wear and tears. And why? And the chain works longer for the dullness to be lost.

When you file by hand, one of the easiest ways to sharpen a chainsaw is by mounting a file into a sharpening guide.

Adjust the Chain

Another factor why your chainsaw won’t cut may be that it isn’t correctly calibrated for your chain. If the adjusting screw is loose, the chain may not be able to comfortably grip the wood.

On the other hand, if the chain is very tight, it cannot be rotating at the proper speed. As a result, it doesn’t cut as expected and you’ll need to loosen the adjustment screw.

Replace the Bar 

The chain bar may even be worn out if the chainsaw doesn’t cut. Normally, along the chain bar, the chain can slide quickly. If it doesn’t then the guide bar would need to be removed.

Often make sure that the oil reservoir is filled with bar oil while you’re using your chainsaw. This is vital for keeping the bar well lubricated in order not to wear out.

Chainsaw Lacks Power

Check Various Components

You can check out the piston, muffler, cylinder, and spark plug for any wear if your chainsaw is having power issues. The exhaust gases would be stopped from entering the engine by a plugged spark arrestor, muffler, or cylinder exhaust outlet, thus reducing engine efficiency.

Carbon could be clogged with these vital components and cleaning them would be a solution. If you use your chainsaw to ensure that your chainsaw operates more properly, you should replace them as well.

In order to power the chainsaw, the piston and cylinder work together to facilitate combustion. The ring in the piston will break off and fall, decreasing its ability to provide the compression required.

If that happens, so the chainsaw is not going to work at its best, creating a loss of control. You’ll need to replace the ring or the piston and cylinder to address this chainsaw problem.

Chainsaw Engine Smokes

Having a smoking chainsaw can be bad news and delay your outdoor project. In most cases, something is wrong with the type of fuel you’re using or your chain bar is too hot.

To narrow down this chainsaw problem, check whether the smoke is coming from the engine or the chainsaw.

Check the Fuel

If the smoke comes from the engine, this is an immediate red flag since it can cause greater damage to the engine. This can be as a result of improperly mixed or contaminated fuel.

A combination of oil and diesel is the fuel used in chainsaws. For various chainsaws, the ratio of this combination varies, but it’s typically 40:1 or 50:1. To ensure that you use the right ratio, review your chainsaw manual.

Fuel containing water, dirt, or even wood particles might be other factors that could make the fuel go bad.

Check the Oil Reservoir and Chain Tension

If the smoke comes from the blade of the chainsaw, either the chainsaw bar is not sufficiently lubricated or the friction of the chainsaw chain is troublesome.

Ensured that the guide bar oil reservoir has enough oil. Than fill it up if not.

If the concern comes from the tension of the chainsaw chain, make sure the chain is not too tight or too loose.
