Frequently Asked Questions

  • Does this come with a battery and charger?

    No, this model does not include a battery. This is an electric tool.

  • I’m really tall/short. Can I adapt the Worx 4 Amp 12” String Trimmer / Edger to my height?

    Yes! The 4 Amp 12” String Trimmer / Edger has an adjustable auxiliary handle so you don’t have to contort yourself to fit your trimmer. Loosen the handle knob and slide the handle to the optimum position for your comfort and balance. Let your Worx String Trimmer / Edger adapt to fit you.

  • How heavy is the trimmer?

    The trimmer only weighs 5.3 lbs. The ergonomic design ensures weight is evenly distributed between the main and auxiliary handle to make trimming a comfortable, easy-to-manage experience for anyone.

  • Does it come pre-assembled?

    Each trimmer comes with some minor assembly required, which may take up to 5 minutes per tool. A step-by-step instruction manual is included along with easy assembly instructions. Please have a #2 Phillips head screwdriver on hand when assembling your String Trimmer / Edger.

  • How do I adjust the Auxiliary Handle?

    To adjust the auxiliary handle, loosen the knob that attaches the auxillary handle to the trimmer shaft. Slide the auxillary handle to the most ideal, balanced position for your comfort and re-tighten the knob to secure the handle.

  • How do I convert the GT from Trimmer to Edger?

    Converting your trimmer from Trimmer to Edger is quick and easy.

    To change the tool for edging mode, adjust the angle of the cutting handle so the cutting head is inline with the shaft of the trimmer. Grasp the handle and the part of the tool where the shaft meets the cutting head. Pull the handle away from the cutting head and twist clockwise. Release, and you’re ready to go!

    To return to trimmer mode, grasp the part of the tool where the shaft meets the cutting head and pull the handle away from the cutting head. Twist counter-clockwise. Release the handle. Adjust the auxiliary handle to the most comfortable position for your height and the job at hand.

  • How do I convert the trimmer to mini mower mode?

    This model does not have a mini-mower mode.

    Mini mower mode is offered on our 20V GT Revolution trimmers.

  • What kind of spools or cutting line does this trimmer use? Can I get the Free Spools for Life offer?

    The Worx 4 Amp 12” String Trimmer / Edger uses the Worx WA0007 dual-feed spool which is pre-wound with 16’ ft of our patented DoubleHelix DNA Line2. The Free Spools for Life will not fit this trimmer.

    For your convenience, we also offer a kit including 3 spools and and an additional spool cap cover to make sure you're ready for the whole season.

  • Can other cutting line be used with the 4 Amp 12” String Trimmer / Edger?

    Our Double Helix line is specially designed to work with the Worx String Trimmers / Edgers and give you a quicker and more efficient cut to help maintain a healthy, professionally groomed lawn. DoubleHelix DNA Line 2 is a patented copolymer nylon resin and synthetic material designed with an oval aerodynamic shape known as DoubleHelix DNALINE2 which increases edging life up to 25% compared to normal use conditions. Designed to be softer, stretch and cushion on impact with hard surfaces, DNA2 trimmer line is durable and flexible for longer life.

    If you decide to use traditional line, the 4 Amp String Trimmer / Edger can accept standard 0.065” cutting line found at any garden or home center and can be wound around our empty spool cartridges. Refer to your owner’s manual for important details about how to wind the line on the spools.

  • What kind of extension cord should I use?

    The right extension cord will ensure you get the performance you expect and will extend the life of your blower. Look for an extension cord rated for Outdoor Use and make sure the gauge of the cord is appropriate for the length you’re using. The WG116 is a 4 Amp tool, so check for gauge and length on the grid here, or in your manual. Your local hardware or garden supply store will be happy to help you select the right cord to meet your needs.

  • Can I use the tool without the safety guard? I have experience with other trimmers and will be the only one using it.

    The safety guard is an essential part of the tool. Not only does it keep you safe from any debris from the trimming/edging, it also helps regulate the length of the cutting line. Without the safety guard, your Worx String Trimmer / Edger will not operate properly and you are at risk for injury.

  • Are there any precautions I should follow when using the Worx 4 Amp 12” String Trimmer / Edger?

    Carefully review the owner’s manual for all safety information and guidelines for using the Worx 4 Amp 12” String Trimmer / Edger. 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.

  • I’ve misplaced my manual. Is there anywhere I can get more information?

    You can download the manual here.

  • What is the guarantee/warranty?

    If you decide the Worx 4 Amp 12” String Trimmer / Edger isn’t the right tool for you, we offer a 30-day Money Back Guarantee from date of receipt (less shipping and handling).

Rated 5 out of 5 by from Light weight/maneuverable Purchased this string trimmer to replace a troublesome gas powered one. The frustration of trying to start plus adjusting the carborator just about every time I used it are all gone! The WORX trimmer is by far one of the best pieces of equipment I have ever purchased and at a very reasonable price. This was my Father’s Day gift which was promoted by WORX on that day. Thanks WORX. You have made my chores a bit easier. This Is from an almost 72 year old.
