Manuals

FAQs

What oil do I use with my chainsaw?
Our units use a standard bar and chain oil. You can purchase this from your local hardware store; no specific brand name is required
Why is my chainsaw leaking oil?
All chainsaws will slowly “leak” oil in storage (mostly from it seeping off the chain). To prevent excessive leakage, store with as little oil left in the reservoir as possible, lay the chainsaw flat with a rag beneath it and the pole saw upright with the motor head at the top. During first use, operators should only fill the reservoir to roughly half full and check periodically to see if it needs to be refilled. Eventually, you will become accustomed to the amount of oil required for each job. This procedure will make it easier to store the unit as oil free as possible and reduce oil run off.
How large of a branch/log can I cut?
If you are looking to cut logs with one pass, the log needs to be about 2" smaller than the bar. However, there are many techniques to use a chainsaw for larger cuts.
What is the run time?
The run time of a chainsaw is measured in cuts per charge. The number of cuts per charge or “run time” that you receive would depend on the load acting on the saw (i.e., the thickness and type of wood being cut) as the chainsaw would use more battery power on tougher and thick objects being cut.
How do I know if my chain is tensioned enough?
Chains should be tensioned before use. Check intermittently throughout each chore to make sure the chain is kept properly tensioned. A correctly tensioned chain should only pull away from the bar enough to fit a dime between the teeth and the bar. ***DO NOT TENSION A CHAIN AFTER YOU HAVE FINSHED USING THE TOOL. HOT METAL EXPANDS. IF THE CHAIN NEEDS TENSIONED WHEN HOT, THEN ALLOW TO COOL, THE CONTRACTING METAL COULD POTENTIALLY DAMAGE THE CHAIN, THE BAR AND EVEN THE UNIT. WAIT UNTIL THE NEXT USE (OR AT LEAST UNTIL COOLED) BEFORE TENSIONING***
Can I use another brand of chain?
Yes, however, it must match the specifications of the original chain (gauge, pitch, and drive links). These specifications my be found inside of your owner’s manual.
What file size do I use to sharpen the chain?
Our chains may be sharpened using a 5/32” round file.
Why isn’t my chain cutting?
If the wood is burning/smoking, this indicates that the chain is on backwards. Another reason could be that the chain is dull and needs to be sharpened or replaced. Replace the chain if: • The length of the cutting edges is less than 5 mm. • There is too much space between the drive links and the rivets. • The cut speed is slow • Sharpening the chain many times but it does not increase the cutting speed.
Why does my chain keep falling off?
Chainsaw chains can come off due to multiple reasons such as worn-down bars, worn-down sprockets, and wrongly set chain tension. Please check the chain tension and condition of all parts prior to using. If anything is worn or damaged, replace parts before using again. Replace the bar if: • the groove is not fit with the height of the drive links (which must never touch the bottom). • the inside of the guide bar is worn and make the chain lean to one side.
How should I store and care for my Greenworks battery to ensure the best performance and longest lifespan?
We want you to get the most out of your tools, and that starts with understanding how to care for your battery. Proper storage and handling not only extend battery life but also ensure your tools are ready to perform when you need them most. A Quick Note on Lithium-Ion Battery Performance All Greenworks batteries use lithium-ion technology, which offers powerful, consistent performance without the memory effect found in older battery types. However, lithium-ion batteries are sensitive to temperature extremes—both heat and cold can affect performance and longevity. That’s why proper storage and care are essential for keeping your battery in peak condition. Best Practices for Battery Storage and Use: Store batteries indoors in a cool, dry location—away from direct sunlight, humidity, or extreme temperatures. This protects internal components and preserves performance. Only connect the battery to the charger when actively charging. When not in use, unplug the charger and keep the battery disconnected. If storing for an extended period, charge the battery fully before putting it away. Check the charge every couple of months. If it drops, recharge it before returning it to storage. This helps maintain battery health over time. Allow the battery to reach a safe operating temperature before use. For snow throwers and cold-weather operation, cold batteries may not power on. Let the battery warm to room temperature indoors before inserting it into the tool. Kindly note: Once the battery is at room temperature and installed, the current generated while the tool is running will help keep the battery warm. As long as the battery starts at room temperature, you should not experience issues even when working in cold outdoor conditions. For other tools/hot weather operation, if the battery has become hot from use or charging, allow it to cool before reinstalling. Indoor storage helps avoid performance issues related to both hot and cold environments and keeps your battery protected year-round.
Can I leave my battery in the charger after charging it?
The battery chargers do have auto cut offs to prevent it from over charging. However, we do advise customers to remove the battery from the charger after it has been fully charged and to also unplug the charger from the outlet, as this is good electrical safety practice to do so. This will also help to prevent false defect readings and allows the charger to reset itself each time it’s used to charge a battery.
Why do batteries cost so much more than the tool?
The battery is the most important component for a battery-operated unit. Please be assured we price our batteries with the cost of material, manufacturing, and current market pricing in mind. Batteries are the costliest items to manufacture and ship in any kit. Full kits including a tool, battery, and charger are priced affordably so that consumers can begin building that line of tools and move forward purchasing tool-only units. When you purchase batteries on their own, it is more notable the cost that they carry.
How do I store the battery? Can I leave the battery in the garage or shed?
When the battery is not in use, we suggest storing it indoors, in a cool dry area - away from direct sunlight. Leave the charger unplugged and the battery disconnected from the charger unless it needs charging. It is recommended to store the battery with a full charge, and if it is being stored for a period where no use is expected, to check on the charge every couple of months. If you notice the charge has dropped, we advise charging the battery back up to full before returning it to its safe storage place. Following these steps will ensure you receive the most out of the battery life.
My battery is stuck in my tool. How do I get it out?
60V/ 80V Products: To remove the battery, push and hold the battery release button. Then, pull the battery pack straight out. In some cases, if the springs underneath have gotten locked down you might have to give a small push to the top of the battery to re-engage them to help the battery pop up. The battery pack fits snugly into the product to prevent accidental dislodging while in use; it may require a strong pull to remove. Before use, be sure that the rails on the battery and product are free of debris that could cause the battery to get stuck. 24V/ 40V Products: To remove the battery, press the latch button on the battery pack down and hold. Pull the battery pack out of the handle. The battery pack fits snugly into the product to prevent accidental dislodging while in use; it may require a strong pull to remove. Before use, be sure that the rails on the battery and product are free of debris that could cause the battery to get stuck.
How do I check the charge on my battery?
Press the battery capacity indicator (BCI) button located at the end of the battery. The lights will illuminate according to the battery capacity level. Please note this switch does require a firm direct push using the tip of your finger. If the button is not being fully engaged, the lights will not activate. Please also be advised the lights only stay on for a few seconds and will automatically turn off. Another reason the lights will not power on is if the battery is completely depleted of power and needs to be charged.
Can I use any Greenworks battery in any Greenworks tool?
Our batteries are interchangeable with tools that are of the same voltage platform only. The difference between batteries of the same voltage is the ampere-hour (Ah) rating. The higher the ampere-hour (Ah) rating on the battery is the more run time it has to offer.
Are there certain tools that can’t accept all same voltage batteries?
There are a few exceptions. • Our 80V 20” snow thrower models 2600402 / 2605202 / 2601302 manufactured prior to September of 2017 can only use 2.0Ah or 2.5Ah battery models. • Our 60V 8.0Ah battery model 2957102 cannot be used in the following tools due to the height: dual-port lawnmowers, pressure washers, or the wet/dry vacuum.
Do all batteries of the same voltage use the same charger?
Yes, they do. Each product line has designated charger models that can charge all batteries in that voltage platform, no matter the Ah rating.
The charger indicates that my battery is fully charged but I was just using it and it depleted. Why isn’t it charging?
Putting a battery that was just in use onto the charger often results in a false full charge signal. Remove the battery from the charger and allow it to rest in a room temperature area for approximately 10-15 minutes before charging.
My charger is flashing red when I engage my battery. Why is this happening?
When the battery is inserted into the charger and the status LED blinks red, remove the battery from the charger for 1 minute, then reinsert. If the status LED blinks green, then the battery is properly charging. If the status LED is still blinking red, remove the battery and unplug the charger for 1 minute. After 1 minute, plug in the charger and reinsert the battery. If the status LED blinks green, then the battery is properly charging. If the status LED is still blinking red, then this likely indicates an issue with the battery or charger and should be taken care of either with our warranty team or by means of replacement.
My charger has a solid red light on it when I engage my battery. What is happening?
This typically indicates that the battery is at the wrong temperature to be charged. Allow the battery and charger to rest indoors at room temperature until they are no longer hot/cold and attempt charging again.
Are your chargers made for 220V or 120V outlets?
Greenworks chargers sold in the USA and Canada are designed for use on 120V outlets only.

Chainsaw

I’m a 73 retired landscaper male.
Took me a little time to get used to not pushing the blade into the tree/Log until it is totally up to speed. But once I understood and caught on to this it ran like my gas one’s with no problems! I also was amazed at how long my battery lasted! Great tool! So far it’s my new go to chainsaw!

Won't cut straight!

The saw is well balanced and has lots of power but something is wrong. I must have ten chainsaws. we own 55 Acres of forest. I have been using and sharpening chainsaws for over 50 years.
I am pretty sure that the chain kerf is too narrow for the bar.
I bought the 80v 18", model a friend of mine has the 60v saw and is dose the same thing, it just binds and won't cut straight at all. I put a old 16" bar and chain on it from a Husqvarna and it works fine with that green works just got it wrong. 🤔

great saw. hard to find proper replacement parts.

I've used this saw for two seasons now and I like the overall performance. I have over 50 years experience with chainsaws. This one does tend to lose it's chain a little more easily that my gas saw that has a larger chain. I cuts as fast as my gas saw. I bought a larger (6Ah) battery and it lasts at least as long as a full tank of gas on my gas saw. It was very difficult to order a replacement bar and chain. I entered the model number as printed right on the saw into your virtual assistant search box and your robot replied with does not match. Thanks a lot--NOT. I am so sick of useless robots. Finding the proper parts should not be so difficult. Finally found what I hope will be the right parts after wasting more than a half hour messing around with your website. The saw is GREAT. Finding the proper replacement parts-----not so much..

Pain in the Gas

I've had a Gas chainsaw for years and it's been years since I've used it because it's such a pain in the Gas. I haven't used it because I hated mixing the Oil with the Gas and then trying to get it started. So after I bought my 80v Tiller and saw I could use the same battery in a Chainsaw I got a great deal on the 18 bar model. It's Wonderful Wonderful Wonderful. Real powerful not too heavy and no Cord because it starts at the touch of a button. And when you put it down you don't have to keep it idling or pull on that Cord again. I cut through nice size Oak limbs with ease so I will be getting rid of all my Gas powered Garden Equipment.

Excellent Performance but…….

Bought this product in hopes to simplify my life and eliminate the need for gas use all together! Chainsaw is great! Cuts just as good as any gas powered saw with less noise and far less weight! I burn 5 cords of wood in the winter and this saw has helped me prepare without issue. Only negative I have with the product is the battery life. 30 minutes max if your lucky. Do yourself a favor and get two so you can interchange them and not have to pause your job completely while you wait for the battery to recharge!

pro 80v 18 chainsaw review

I recently purchased this chainsaw because I wanted to see if the previous reviews were accurate and I found out that this chainsaw is worth the money. I appreciate being able to pickup and go (still have to adjust chainensure battery is charged and add bar oil). Would recommend this chainsaw to anyone.

Less Fatigue and no disappointments

I am very pleased with the performance and benefits of using the 18 chainsaw. No smelling of fumes the safety of almost immediate blade stop when not in use no pulling a cord to restart so much less noise than the gas alternative. There is so much less vibration and fatigue as well. I have four acres of heavy woods and I can take care of a fallen tree early in the morning and never worry about upsetting the neighbors.

Excellent Chainsaw.

I have had my share of Gas powered chainsaws. I live up North and during winter most summer gas powered tools get winterized and then then stored away. Next Spring it becomes a 1 or 2 day event trying to get everything to start running and stay running.Bought the 80V Electric Chainsaw. Upgraded Chain to something more aggressive. Then started to remove 13 - 30 to 40 foot Boxelder or green ash trees from the property. The Electric Chainsaw had no issue with downing and then cutting up the firewood form the trees. Purchased another Battery to have one charging while one was working. Love how quiet the unit is and not having to fight to pull a rip-cord to get the thing started. Just press button and go.I have started to switch out my terrible gas powered items for whatever 80V tool is available. See other reviews

Solid Tool

I recently purchased this chainsaw when the body of my previous corded chainsaw cracked. In the short time I used it I have cut and split about a 1/2 cord of wood mainly sweetgum but some oak as well. The saw has held up well and I had no issues with it. I was very happy with the battery life on the saw as I was expecting to have to change batteries fairly often but that was not the case. I did not have to change them once during any of my cutting sessions. One of the things I really like is I can take this anywhere without dragging a cord around and its it quite. The only change i would like is to lengthen that amount of time it takes before the saw shuts off and you have to press the power on button again. Its a quick press but still a little annoying when you have the saw positioned but you have to turn it back on to proceed. Regardless I would recommend this saw.

Good Chain Saw

Had a dead tree to fell but was concerned about going electric. This Chain Saw worked great and had enough battery for the complete job. Gave 4 stars only because it didn't come with chain oil so I had to make a separate run to buy some before using. Otherwise as advertised and worked well.

Woman-friendly

This is exactly what I was looking for in a chainsaw. It can cut through larger trees and it isn’t too heavy for me to comfortably use. The battery life is good and no gasoline fumes. The battery charges quickly and I love the chain tightening wrench conveniently located on the bottom of the chainsaw.

Couldn't be happier.

Couldn't be happier with this little tool. All the power you could need to get through a good sized tree. If you're chopping down a forest battery isn't for you but for relatively light work this is perfect.
