What is 4 stroke chainsaws?

What is 4 stroke chainsaws

A 4-stroke chainsaw is a regular chainsaw that runs with a 4-stroke engine. In other words, it is known as the 4-cycle chainsaw.

On the third stroke of a 4-stroke chainsaw, oil is drawn from a dedicated oil reservoir and delivered into the chainsaw to lubricate it. This occurs on the third stroke.

Because the chainsaw has a separate oil reservoir as well as a stroke that is specifically designed for lubrication, there is no need to combine oil and the fuel that it uses to operate.

A 4-stroke chainsaw is a lot quieter than a 2-stroke chainsaw, and it provides a lot cleaner and more flexible power with very low fuel consumption and emission. For that reason, a 4-stroke chainsaw is much suggested.

Difference between 4 stroke vs 2 stroke chainsaws?

Difference between 4 stroke vs 2 stroke chainsaws

Chainsaws powered by two-stroke and two-cycle chainsaws are often more powerful than those powered by four-stroke chainsaws, making them more suitable for more demanding work.

Since 4-stroke chainsaws are often quieter and more fuel-efficient, they are an excellent option for tasks that need less power. It all depends on what the chainsaw is going to be utilized for to determine the best option.

Compared to a chainsaw powered by a 4-stroke chainsaw, one powered by a 2-stroke chainsaw has fewer parts, making it both lighter and more compact. A reduction in weight makes it simpler to carry and operate at the same time.

Since the compression is smaller, the blade of a 2-stroke chainsaw moves more freely than a 4-stroke chainsaw. This leads to a more responsive and impressive throttle.

If you are using a two-stroke chainsaw, you can get from idle to full throttle in a matter of seconds.

Although a 4 stroke saw is more powerful at lower RPMs, it can’t accelerate as rapidly. With 4 stroke saws, timing lag is commonplace. When the chainsaw has to accelerate quickly, this causes a delay in advance of the valve timing.

The time of the spark may be readily advanced due to the fact that electricity travels at a high rate of speed. It takes time for the valves to advance mechanically, which slows down acceleration.

So, 4-stroke chainsaws are preferable when torque is needed across a wider rpm range, but they are not as excellent at quick acceleration as two-stroke chainsaws.

In spite of this, 4 stroke saws still cannot match the quick throttle response provided by 2 stroke chainsaws.

How to sharpen a chainsaw with a flat file?

How to sharpen a chainsaw with a flat file

Using a flat file is the oldest and easiest method of sharpening a chainsaw chain that anybody can use at home. For that method, you will need a few flat files, safety goggles, gloves, and a bench vice.

Step 1:

While the chain is still in the bar on the saw, put it upside down in a very little stunk device that is just pounded down into the end of a piece of firewood as it holds the saw nice and stable.

Step 2:

Then tighten the chain up to the maximum level so that you will be able to move the chain, but it won’t wiggle around while sharpening.

Step 3:

The role of the two sets you want to sharpen and bring them to your suitable position of the chainsaw.

Step 4:

Take a piece of wood with marks of 30, 20, and 25 degrees across it and pick any mark you want according to your choice. And put the piece of wood below the bar perfectly.

Step 5:

Hold the file over the mark so that the file stays in parallel with the mark, and start filing the tooth you have selected. This is very important to keep the file in line with the mark across the bar at the selected angle.

Step 6:

Be very careful about your stroke and control over the file, and don’t try to rotate the file.

Step 7:

You can continue the process of moving and flipping the chain for all the other teeth.

Step 8:

Get the chain off the chainsaw and place it on a bench vise that holds the chain nice and tight. You can carry on the tooth sharpening process on the bench vise if you want.

Step 9:

The teeth in front of the cutoff teeth, known as rakers or depth gauge teeth, need to be smoothed down with a flat file to the same height as the cutoff teeth using the same process.

Thus, you can easily sharpen a chainsaw with a flat file.

Buying Guide: Best 4 Stroke Chainsaw

Chainsaws come in different features, sizes, and purposes of use. To get the best result you should consider some facts. Otherwise, you may have to face a great loss.

We have gathered some facts that are needed to be considered to avoid any potential risk or damages before buying the best 4 cycle chainsaw.


When it comes to size, there are a lot of things to consider. Do you have a place to put your chainsaw away? Before making a purchase, make sure to check the saw’s length, height, and breadth measurements.

It’s important to consider the saw’s weight and whether or not you’ll have no trouble maneuvering it. Never, ever purchase a giant saw to bolster your self-esteem!

Taking into consideration your age and overall fitness is essential. If you can easily lift an 11-pound weight, you’re in good shape. It’s one thing to use an 11-pound saw for a few minutes.

It’s quite another to use it continuously for 30 minutes until exhaustion kicks in. There is a greater risk of a disaster if you use a saw that you can’t manage correctly.

Engine Size:

The cubic centimeters (cc) scale is used to measure the power of gasoline-powered saw engines. More Chainsaw-engine power is created with higher CCs, but the weight penalty is larger.

For most households, a motor between 30 and 45 cm3 would do the job. Engines may be as little as 23 cm3 or as large as 120 cm3.

If you want to get an idea, a 30 cm3 engine produces approximately 1.7 brake horsepower (bhp) and a 45 cm3 engine around 3 BHP.

Power Option:

There are two types of power options available for chainsaws: cordless battery powered and corded electric powered.

Choosing a cordless chainsaw allows you to use it anywhere you like. However, you’ll be annoyed by the short battery life and constant recharging.

When working for an extended amount of time, it’s inevitable that you’ll need a lot of batteries charged beforehand.

But corded chainsaw won’t have such an issue. Just the extra cords may bother you a little.

FAQs – Frequently Asked Questions & Answers

Best 4 Stroke Chainsaw

Why should I lubricate my chainsaw?

The chain on a chainsaw is needed to be lubricated against the bar. It’s not a good idea to have too much friction in your chain since it might cause it to explode.

The chainsaw’s engine is also affected by the lack of oil.

What sort of oil do I use for the bar and chain?

Always lubricate the bar and chain. Automated oiler system lubricates when oil tank is full. Without oil, the bar and chain will break.

Plus, oil insufficiency causes a smokey chain or discolored bar from overheating. When the temperature goes below freezing, thin bar and chain oil with Diesel Fuel or Kerosene form wax that blocks the filter.

Free-flowing oil allows the oil system to pump enough for optimal lubrication. So, use only the Poulan bar and chain oil to avoid heat and friction damage. Poulan oil is heat-resistant.

How should I lubricate my chainsaw?

Some chainsaws come with a self-lubrication system. If your chainsaw is not one of them, you may need to follow the instruction guide that comes with the chainsaw for lubrication.

Or there are plenty of videos available on YouTube about lubrication that are very helpful in this process.

Can I use my chainsaw in the rain?

If your chainsaw is water-resistant, you may be able to use it in the rain. If not, you should avoid using it as it will damage the internal machines inside the chainsaw.

How should I clean the air filter?

Every five hours of usage, inspect and clean your unit’s air filter. Clean the top cover and the area surrounding it before removing the air filter to prevent dirt from falling into the carburetor chamber.

Remove the saw’s top cover. Rinse it with soapy water after removing the air filter. Using clean water, wash it off. Before reinstalling, allow the filter to air dry fully.

Squeeze off any extra bar and chain oil from a foam filter with your fingers before re-oiling it. Replace the top cover and the filter.

These days many chainsaws come with an automatic air filter cleaning system. If you have any of those, you won’t need to go through all these steps.

Why should I use a low vibrating chainsaw?

Vibration from chainsaws may induce weariness, soreness, cyanosis, and, in more severe instances, Raynaud’s illness, in which the fingers of both hands become white due to impaired circulation, resulting in numbness and poor control.

In this article on the best 4 cycle chainsaws, we have analyzed a few low vibrating chainsaws, and these can be your ideal tool for chopping.
