Performance and Handling 

The performance is always linked to how the manufacturer made the product. The saw is perfect for trimming trees and cutting logs that are 10 inches or less in diameter. It is suitable for small tasks around the home like pruning small trees and cutting small amounts of firewood for campers. This saw is not appropriate for critical and heavy work like cutting heavy logs or larger trees since it is lighter, a gas saw may be appropriate for these uses. It is likely to breakdown if it used for heavy duties.

The DeWalt 20v chainsaw is operated using a battery so it has a lot of advantages compared to the gas chainsaws. It is easy to start so any beginner can be able to operate and it does not emit fumes so it is safe to use. It is also quieter so you can be able to use it without distracting other people.

Cutting Equipment 

The saw has a 12inch reduced kickback bar and a low kickback chain which is efficient for the tasks it carries out. The saw has a tool-less system which ensures that the chain has correct tension. The procedure for correcting the tension is fully explained in the manual. When the chain is new, ensure you check the tension now and then because new chains tend stretching slightly. For the best performance, ensure you sharpen your chain every time. You can sharpen the chain yourself by using a 4.5mm file and a file holder or you can take it to local shops for sharpening.

Regarding the bar, ensure you stick with the 12inch bar that comes with the product. Don't try to make it longer since it will bring out the low performance

Regarding the gear, the saw has a chain speed of 7.7 meters a second. It is a little bit slower compared to the gas model but it is quite efficient for its tasks.

Design and Construction 

The DeWalt 20V chainsaw has a design that is dense and lightweight. As expected from all DeWalt power tools, the saw is perfectly constructed and it is comfortable to the user. It has a good balance so it can be handled easily. Its battery is located perfectly into the back of the bower unit below the rear handle. The main features of the chainsaw include:

  • The safety guard or the Handguard
  • Battery housing which ensures the battery is held neatly
  • Oil level indicator that shows the oil that is remaining
  • The oil cap that reduces oil leakage
  • Chain tensioning knob
  • Bar adjust locking knob

The main parts can be accessed easily by the user so it brings some type of comfort during work. The handles are also large so anyone can use them. It also has a good grip so the user has maximum control over the power tool.

Brushless Motor With 20v Max Battery

This DeWalt saw comes with the latest technology. This includes a brushless motor which is now becoming popular compared to the old brushed motor. Brushless motors are more efficient therefore it ensures the motor runs for a longer time and it extends the motor's lifetime. The battery of the saw has 20V and 5amp hour lithium-ion.

When it comes to how long the battery runs, Amp Hours is very important. The higher the Amp-hours, the longer the battery takes to run. This saw has 5 amps an hour therefore it has higher endurance which only a few saws have. Users have said that they mostly use between 45 minutes and 1 hour depending on the intensity of cutting.

If you have any batteries of DeWalt 20V max tools, you can use them in your chainsaw. If your 20V max batteries have different amp hours, you can still use them on the saw. The product comes with its charger which can fully charge the battery in only 1 hour.

Chain Oil System 

The DeWalt 20V Chainsaw has an automatic oil system which ensures the bar is always lubricated. This feature has its pros and cons. The main advantage is that you don't need to remove the oil to the bar for it to start cutting. The disadvantage is that there is no right mechanism that adjusts the rate of flow of oil to the bar and some customers also say that there is leakage when the saw is not in use. This, however, can be corrected by proper storage of the saw.

The use of vegetable oil is highly advised when pruning so that the tree is not harmed. Waste oil is highly discouraged because it causes fast damage to the saw. There is an oil level window at the front of the saw which enables the user to regularly check oil levels. Ensure you fill it when it becomes a quarter full.

Safety Features 

  • The saw has many safety features that is why it is more preferred. These features include:
  • It has a safe starting system which ensures the user cannot accidentally press the trigger button.
  • It has a bar and chain which is designed to reduce the frequency and extremity of a kickback
  • It has a ripped bumper. These are ribs that are situated at the front of the saw which give the saw stability when cutting.
  • The saw has front and back handguards that safeguard the user's hands when he or she is using the saw. I recommend wearing gloves to give more protection.
  • It has a motor chain braking system. During a kickback, the user's left hand automatically pushes against the front handguard which pushes it in a forward position. The chain will stop immediately when this happens.
  • As much as this saw has many safety features, it is not a promise that you will be safe. Make sure you wear safety gear like safety glasses to keep you safe.


The saw is very light as it only weighs 8.8lbs. That is within the handling capacity of most users. When you include the battery, it weighs about 10.2 lbs., which is still most users handling capacity. In short, the saw is quite manageable for every user.


Accessories are items that accompany the power tool. They include a battery, charger and the protective bar cover

Things We Liked About It 

The quality of the DeWalt 20v is without a doubt the best point. It is very well constructed to fit the user's hand and it will certainly last for a long while when taken good care of and put in good condition.

Maintenance of the saw is also a great feature. Since it is powered by battery, it does not need so much attention on maintenance as I would have expected. What you need to worry about is your safety and battery levels of the saw.

This is an affordable tool so everyone can be able to get it. It is a very high-quality power tool so for it to be affordable is a likable thing. Even though it does not ensure professional performance, the tool can cater for all outdoor jobs at home.

The safety features that come with the tool are also an impressive thing. DeWalt has shown that they also care for the customers using their products. This helps the customer to have some confidence in the tool.

Things We Didn't Like

The tool does not include any oil. This may not look like a big deal but it is, at some point. Let's take, for example, an inexperienced user, he or she may have a hard time using it. Ensure you fill the oil before it completely dries out becomes when that happens, the whole machine will be at risk and always check the oil levels before using the saw.

The machine has an auto-filling system that leaks when the saw is not in use. This causes wastage of oil and it becomes hectic to refill the oil.

Buying Guide

Buying the best quality chainsaw is not an easy task as many would presume. You need to buy a tool that will give the best performance and will last longer. The following factors will help you buy the best chainsaw:

Easy Maintenance

For example, if you want a saw for light cutting and which is easy to use and handle, then the best chainsaw for this is DeWalt 20V chainsaw. This chainsaw is considered the best by homeowners because it is light in weight so the user does not tire easily.

Q: How Do You Use A Dewalt 20v Chainsaw?

A: The tool comes without any bar and chain oil. Before using it, you need to fill up the reservoir and properly seal it. Check if the chain has proper tension and finally check If the chain brake is working. When everything is working perfectly, put the battery in, release the chain brake, turn the saw on and flip the chain brake forward. Getting the saw started is a very easy task. Press the trigger button and it will be ready to start cutting. If you are using it for the first time, then ensure it runs for 90 seconds. You will need to adjust the chain tension now and then so make sure you do that.

Q: Does Dewalt Make A Chainsaw?

A: DeWalt is a popular brand of power tools and hand tools which has become popular over the years. In 2011 DeWalt started productions of many hand tools including the chainsaws. They make chainsaws and they continue improving the quality each time. The DeWalt 20V is among the first cordless chainsaws made. They have also made other chainsaws which include: DeWalt chainsaw 60V and DeWalt chainsaw 40V. They all have different features but not so different because they are just improvements for the previous chainsaws.

Q: Can You Use A 60v Dewalt Battery On A 20v Tool?

A: Yes, the 60V battery is very compatible with a 20V tool so you can use the new battery on the old 20Vtool. This ability to change between two voltages is a very important advantage to the user because it ensures efficiency. A higher voltage has many advantages; you'll use a few amps for the same number of watts. This means that you don't have to buy a whole 60V tool, you just need the battery. This helps the buyer to save on money. The 60V battery increases the runtime by almost 4x the original runtime. This makes work easier and gets the job done quickly.

Q: Is 40v Better That 20v?

A: Generally, the higher the voltage, the more power so the cutting is faster. 40V tools are more efficient because they do the tasks better with low energy. The only disadvantage is that the 2 are not compatible. The DeWalt 20V has a lower voltage because it is used for light jobs pruning trees while the 40V is mostly used by professionals that is why it needs a lot of voltage. Both voltages have their advantages and disadvantages, so it is up to the buyer to get the one he or she prefers. If you are a homeowner that needs a chainsaw little tasks around your home, then I highly recommend the 20V.

Final Verdict and Recommendation
