Frequently Asked Questions

  • Does this come with a battery?

    Yes, this model includes 1 battery.

  • How much does the JawSaw weigh?

    The Worx JawSaw weighs 7.9 pounds with the battery installed, about the same as a gallon of milk. Not only is the weight balanced for the best ergonomic experience for our users, the innovative jaw design helps support the weight of the tool and make it easy to use when cutting overhead branches.

  • I’ve seen the JawSaw described as battery-operated and electric. Which is correct?

    We have two versions of the JawSaw, so they are both correct. The WG320 model is a cordless tool powered by our 20V MaxLithium batteries. Our electric JawSaw is model number WG307 and can be found here.

  • What’s the runtime for the JawSaw?

    The runtime will vary depending on the type and density of wood you’re cutting and how thick the branches are for each cut and the capacity of the 20V battery you’re using. For example, on one charge of our 1.3Ah 20V battery, you can expect up to:

    50 cuts in 2” diameter hardwood

    29 cuts in 3” diameter hardwood

    18 cuts in 4” diameter hardwood

    Your yield may vary if you’re using softer wood, or our 4.0Ah 20V battery.

  • How long does it take to charge the battery?

    The enclosed charger and battery take about 3 hours to fully recharge.

  • What is the largest branch that the JawSaw can cut?

    The JawSaw can handle branches up to 4" in diameter.

  • What is the chain speed?

    The no load speed for the Jawsaw is 1350 rpms.

  • Does the JawSaw come pre-assembled?

    Yes, the Worx JawSaw comes fully assembled. Just oil the chain as instructed in the manual, install the fully charged battery, and you’re ready to work!

  • What kind of oil do I use on the JawSaw?

    To oil the chain, use a winter-weight bar and chain oil which is available in most hardware stores or stores that sell chainsaws.

  • What is that red thing attached to my JawSaw’s cord used for?

    That is the service key, which puts the JawSaw in "service mode" and prevents it from accidentally operating. When in service mode, the bar and chain can be removed & the chain can be tightened.

  • How do I sharpen the chain?

    If you want to sharpen the chain yourself, we recommend the Oregon 25894 5/32” file with guide, and the Oregon 27742 Depth gauge and file guide, for the best results. You can also check with local hardware stores for professional sharpening services.

  • How do I buy a replacement bar or chain?

    Both the bar (WA0162) and chain (WA0161) are available under Accessories.

    JawSaw 6” Replacement Chain

    JawSaw 6” Replacement Chainsaw Bar

  • How many chain links are on the JawSaw chain?

    There are 42 links on the JawSaw chain.

  • What other types of replacement chain should I use?

    Because of the unique design of the Worx JawSaw, we only recommend using the Worx replacement chain.

  • I saw an extension pole as an available accessory. Is this required for using the JawSaw?

    The JawSaw can be used with or without the extension pole. The extension pole is designed to help reach branches up to 12’ high and can be quickly and easily attached or detached depending on how you need to use the JawSaw.

  • There are two different extension poles. How do I know which one is right for my JawSaw?

    There is an extension pole for the electric JawSaw and one for the battery-operated version. Be sure to select the type of extension pole that matches your JawSaw:

    WA0169 Extension pole for Cordless/Battery-operated JawSaw (model WG320)

    WA0163 Extension pole for Electric JawSaw (model WG307)

  • What is the weight of the tool with the Extension pole?

    The total weight of the JawSaw and extension pole is 11.6 pounds.

  • What is the length of the JawSaw and the Extension Pole?

    Jawsaw is 33 inches (or 2 ft 9 inches) and the Pole is 61.5 inches (or 5 ft 1.5 inches) in length. When used together, the total length is around 7 ft 9 inches.

  • If the total length of the JawSaw and extension pole is less than 8’, how can they reach up to 12’?

    Working directly overhead is never a safe option when trimming limbs from trees, so the calculation isn’t based on direct reach. Since the safest way to approach tree trimming would be standing away from the branch being cut and reaching up at an angle, the total reach factors in the average height of the person using the tool as at least 4’. When standing at the base of the tree and reaching with the JawSaw at an angle, the average user can cut branches at a height of 12 or more feet.

  • Why do I have to pay s&h on the extension pole accessory?

    The extension pole comes pre-assembled making the box an oversized box in length and therefore cost extra to ship.

  • Are there any precautions I should follow?

    Carefully review the owner’s manual for all safety information and guidelines for the JawSaw. Follow safety precautions while using any power tools – including wearing safety eyewear, gloves, appropriate shoes & clothing, and keeping hair tied back. See the owner’s manual for complete safety instructions and details.

  • What is the guarantee/warranty?

    If you decide this Worx JawSaw isn’t the right tool for you, we offer a 30-day Money Back Guarantee from date of receipt (less shipping and handling). Please call our customer service center at 1-866-354-9679 (WORX) and we’ll be happy to assist. View more information here.

Men's Journal

"When the WORX JawSaw debuted, we praised it as a safer, smarter chain-saw alternative. Its steel teeth hold branches up to four inches wide while an enclosed six-inch blade makes clean, quick cuts without endangering limbs. The latest iteration, the 20V 2.0, is even better, powered by a lithium-ion battery good for 20 minutes of cord-free use."

Rated 5 out of 5 by from Light, Simple, Rugged. My kind of tool! I bought this saw recently, and the first time that I used it was an eye-opening experience. I have been using chain saws for years, and have been having good luck with them, both gas and electric powered. But this saw was amazing in that it did all of the things that the promo material said that it would do. I opened the box it came in, read the instruction manual, adjusted the chain per the instructions, filled the chain oiling tank, charged and installed the battery, and had a very pleasant experience trimming my trees. One of the best features of this saw is that the battery lasts just about as long as I do, and we both get to take a break at the same time.

Rated 5 out of 5 by from Great Handtool! I bought this for my dad because he is always needing to trim limbs from trees and limbs in the ground. This tool does the trick! It snaps up limbs into smaller pieces!

Rated 5 out of 5 by from Super light The jawsaw is fantastic, I am 5'4" and I can easily handle it to trim branches. I no longer have to wait for my husband to have time to pull out the big chainsaw! I like that the blades are kept tucked away until I activate the tool.

Rated 5 out of 5 by from Little JawSaw Chainsaw is a monster Super easy to use. Speed up my yard work. Can cut four 1/4" dia. branches with ease, but cut them slowly and evenly. Read instruction manual means BUSINESS. Watch your feet first before cutting ... you could be overlooked if carless. Spending most of the day cutting several trees with breaks and charging. Worx chain saw bar oil is much thinner than the "regular" bar oil at stores. My concern is using thicker bar oil when cutting outdoor at 25 degree F or colder. Two cycle fuel mix chain saw runs much warmer than Worx JawSaw Chainsaw to keep bar oil warm and will will flow freely. I hope to get a feedback from Worx soon using thicker bar oil.

Rated 5 out of 5 by from So far so good!!! I bought this for my husband for Xmas but gave it to him early due to the 30 day guarantee, he used it recently and loved it...He was psyched to be able to clean up a fallen dead tree due to windstorm. It’s lightweight and just what I hoped it would be for him.

Rated 5 out of 5 by from Love, Love, Love this saw! I've only had the JawSaw for a few weeks and so far I haven't had any problems. I love it! I'm a 48 yr old female and this tool easy to use and gets the job done with ease. It effortlessly cuts through trees up to 4". I love being able to snake the tool between brush to reach a sapling and cut it by pushing a button. Its so easy to use and completely safe. The battery outlasts me between charges so it's perfect.

Rated 5 out of 5 by from Light and easy to use I am an elder lady with a bad back that needs to keep up several acres. Power for light saws not available where trimming and cutting is needed on property. Battery lasts as long as I can. I have several worx tools so if I have help I use batteries from other tools.

Rated 5 out of 5 by from UNBELIEVABLE!! Don’t wait!! We have a lot of trees on our property and I’m always amazed at how many branches drop every year. That combined with trimming and the trees that come down makes the JawSaw a must have. I’m angry I waited so long. This tool saves so much bending and cutting by hand. If you were to take down one medium sized tree and use the JawSaw to cut it up you would pay for the tool in my opinion. I’m sold!!! Bought into the program with the other tools and now have six batteries. Love the Worx cordless family of tools as it has made my maintenance of my property so much easier.

Rated 5 out of 5 by from 20V Jaw Saw Cordless Chainsaw I bought this ( Cordless Jaw Saw )tool because of the cost to have a tree trimmer to come and trim my Red Maple at the bottom and what he was going to charge me and also my neighbor that needed her tree trimmed at the bottom. It was hard to cut our grass because of the limbs being so low on our trees. I love this tool. It as paid for it's self several times. I have used this tool in other areas.

Rated 5 out of 5 by from Really easy to use I've used this JawSaw twice for about an hour each time. It never needed a battery change even though I was cutting 3" juniper branches which usually gave my gas powered chainsaw fits due to sap. I didn't feel that I'd even exerted myself after cutting the branches into 24" disposable pieces. Maybe it's because I didn't have to pick the branches up, just went down the branches and cut every 24". Also the saw cut so quickly that I did no work other than just being there.. This is a winner Worx product.. Thanks for another great one..!

Rated 5 out of 5 by from I love this thing One of the ladies at the lake we visit had one of these and raved about it. I used it and loved it as well. I just bought one of my own and have completed so much yardwork that I could not have completed without this tool. It is great for anyone afraid of a chainsaw.

Rated 5 out of 5 by from Great for small stuff No extension cords or mixing fuel. Take it anywhere. I am really pleasantly surprised at the battery life. The battery holds up very well. Not good for large projects, but is great for small work. I have not had to start my gas powered chain saw since I got this. The only drawback is; if it doesn't fit totally in the opening it doesn't get cut. I do however, realize that this is a safety feature.

Rated 5 out of 5 by from Used it once so far, works like a dream Took only 15-20 mins to set up - basically involving filling it with the lubricant and getting the chain tension right, and it was ready to go. It lopped off branches as promised with minimal effort as you squeezed the handle into the tool to make the saw rotate on its fulcrum and apply the cut. And it felt really safe operating the saw. My first ever saw - and I am glad I opted for it
