The Greenworks 40 volt chainsaw with a 16-inch bar is a perfect chainsaw for a wide range of users and projects! From beginners to experienced professionals this chainsaw will meet their needs. The 0.043 inch chain gauge is thinner than the Greenworks 40 volt 12 inch bar chainsaw that is 0.005. A slimmer chain and the longer bar allow for cutting up to 30 inch diameter logs!

The Greenworks 40 volt family of tools consists of more than 25 products with high efficiency motors and they are built better than the cheapest saws and are more affordable than the commercial grade chainsaws The universal 40-volt battery provides ample running time for normal projects and the engine has similar power to a comparable gas saw.

A heavy-duty Oregon bar and chain is built to last, and with the Oregon name you can be certain the bar and chain is made from quality products ensuring high performance as you quickly and efficiently get your cutting done.

The featured digital controlled brushless motor on this chainsaw delivers longer run time and 30% more torque for better cutting power and 70% less vibration for user comfort.

An automatic oiler keeps the chain lubricated as you work, keeping the chain and bar from overheating and becoming damaged. An electronic chain brake prevents operator injury from kickback and provides a way to instantly stop the chain.

Battery Chainsaws Are Low Maintenance, Reliable, and Efficient

A battery powered chainsaw offers many advantages compared to gas chainsaws. Among the most important are little to no maintenance throughout the life of the chainsaw, you will never replace a spark plug or need a costly engine tuneup from a small engine repair shop.

The fast and easy start at the push of a button is convenient, preventing a stubborn gas chainsaw that won’t start. You can forget about the difficulty of using a pull rope trying to start a gas chainsaw that has been sitting on the shelf all winter. No more trips to the gas station because you ran out of gas.

Other benefits are reduced noise, battery chainsaws operate much quieter than gas chainsaws which is especially useful if you have close neighbors. No smoke or gas fumes means you can cut indoors and is also
environmental friendly.

People that have purchased this saw were impressed by power and extended battery life this chainsaw offers. Many of them previously owned a gas powered chainsaw and now the battery powered chainsaw has become their new favorite, causing the gas chainsaw to stay on the shelf, likely never used again!


Safety Tips From My Experience With Chainsaws

Use caution when cutting broken down limbs or big storm damaged trees. Many of the limbs on the underside are under tension from holding the branch or trunk up and will pinch your chainsaw bar if you cut them improperly. You will need to determine where the best place to cut is and possibly start cutting on the underside of branches and cut upward to prevent the bar from pinching.

Be careful when cutting above your shoulders or head, the branch is helping to support the chainsaw, plus you may be pushing the chainsaw down on the branch and when the branch is cut through the chainsaw could drop toward your legs if you are not prepared.

Be cautious of kick back, the chainsaw brake will automatically be deployed and stop the chain immediately in case of severe kick back. To prevent kickback always keep a firm grip on the top handle and do not cut with the top of the chainsaw bar nose. When that small area on the top of the end of the bar touches wood the moving chain will suddenly kick the saw back and up.

A simple tip on how to check the chain tension on the chainsaw, place the saw on a flat surface and pull the chain approximately 1/8″ away from the guide bar using your thumb and finger. It should easily pull away from the guide bar at least 1/8″ and when you release the chain it should go back to the bar and in the chain groove. Also, while the chainsaw is sitting at rest there should be no sagging belly in the chain on the underside of the guide bar.

Keep a sharp chain on the saw, a sharp chain cuts much faster and is actually safer to use than a dull chain. With a dull chain you will stress the chainsaw motor and you will need to push harder on the saw to help it cut, resulting in less stability for yourself.

New chains may not look dangerous, but they have many small razor sharp teeth designed specifically for cutting wood. Leather work gloves can be worn while cutting wood and when handling or replacing sharp chains. I have already cut my finger from a sharp chain because I was not wearing gloves.


Concluding Thoughts

As a co-owner of a family owned Tree Pruning and Removal business I am thankful I have plenty of experience to share with you about chainsaws! I believe a battery operated cordless chainsaw is an excellent choice for home use as well as professional use. It will provide more than enough power for cutting needs around the home and will also cut plenty of firewood. They are a great choice for construction and demolition projects in urban areas where there may be sound restrictions.

This chainsaw is one of the most popular models made by Greenworks and is able to take care of almost any job around the house or farm. If your interested in a bigger chainsaw, the Greenworks 80 volt chainsaw with an 18-inch bar also has comparable power to a gas engine!

Chainsaws are fun and enjoyable to operate and I enjoy my job as I get to cut many large trees! I hope you love your new chainsaw and enjoy cutting wood with it! Be sure to have at least one extra chain on hand. A chain will stay sharp for a long time, but cutting into the dirt or nicking a stone will dull it in a hurry. If you accidentally cut into a rock it will become dull immediately.

If you already own a chainsaw I would love to hear about your experience from using it or if you have any other questions or comments I will try my best to answer them.

  1. Hi Justin! Great blog on the Greenworks 40 Volt Chainsaw. I learned a lot about chainsaws that I didn’t know before. I learned how powerful they are and how they’re easy to handle versus gas chainsaws. It’s good you put some safety tips in there. No one wants to injure themselves. I love that you have so much knowledge in this area. It makes your website very trustable. As for someone like me that doesn’t know anything about chainsaws. Keep up the great work! You write very well and clear which is appreciated. 💖😊

  2. Hi Justin. I know nothing about chainsaw but it will be very useful to have one. My husband maintains the trees around our house compound. Trimming them when they get too bushy. And he is only doing this with a handsaw. The next day, body aches kick in. As he is not getting any younger, this battery-operated chainsaw would be most useful. Thanks for your recommendation!

    • Thanks for your comment! A chainsaw would definitely save time and would make the job much easier.

      I have done some cutting with a handsaw and it doesn’t take long to get tired of how slow it is!

  3. Hi Justin, I experience your fondness of cutting trees, when reading your article. You’ve explained the process very well, and also highlighted the features of the chain saw very well.

    With regards to the safety tips – How about adding a few simple sketches on how to do the cutting, because my experience is that some people will have understanding with smalls sketches which accompany your explanation.

    Another suggestion: How about promoting some products, such as the chain saw and gloves, as well as spares?

    Thoughts for later: When you had some feedback from other users, how about adding a few testimonies, or even perhaps real life stories, of how chain saws came to the rescue in specific situations (such as storms, old trees falling over, etc.)

    • Thanks for reading and leaving your thoughts! I will try to keep improving my articles with images.

      I plan to include other products like gloves and other safety accessories needed while using chainsaws.

      It would be a great idea to include stories of real life emergencies that a cordless chainsaw saved the day!

  4. Living in London UK, there are many beautiful parks, where the trees have been brushed down, cleaned, pruned or removed!

    I don’t do any DIY, tree cutting or removal myself and i’m not a gardener(though some of my friends are).

    If i were a professional tree pruner, construction engineer or a home owner, i would definitely be in use of the cordless chainsaw model. The fact that you don’t have to pull a rope, no obnoxious noise or fumes, is definitely a thumbs up!!!

    Just a couple of questions to ask. 1/  what is the difference between an aborist(tree surgeon) and a lumberjack? 2/  if i owned a beautiful house with a lovely garden could i use the cordless chainsaw to prune the shrubs?

    I really enjoyed the video, advertising and marketing the cordless chainsaw.

    The recommended safety tips – excellent!

    • Thank you for taking the time to leave a few of your thoughts!

      A lumberjack would describe a person who works mostly in the forest gathering trees to take to a sawmill for processing.

      A tree surgeon is somebody who works on trees in residential areas, pruning the tree for its health or removing trees for the safety of people and their property.

      You can use a chainsaw to prune shrubs if they are fairly large, for pruning small shrubs you would want to use a hand pruners to snip the branch.
