before I start, it's 5 stars from me - love this unit and I'm returning right now to buy a replacement. More on that below. Included some photos so you can see how the gunk will build inside the unit - gunk can build up exactly where the motor tries to breath! So I did my very best addressing this with some tips below. some care and usage tips after 1.5y solid runtime: - regularly CLEAN THE VENT HOLES for the motor at the head of the unit - it needs to breath. Use Qtips, for example, and perform these maintenances before or after EVERY RUN to keep the gunk from getting "pushed" in further by more gunk. - Edit: Turns out a WIRE BRUSH is enough 99% of the time. QTips not needed. I've been doing it *before* runs when the gunk buildup is dry. When I look into the vent holes, I can see this is doing a good job. Convenient, fast, and easy to do. - Mind that these small vent holes (at the top of the motorhead) are AIR INTAKES - so they attract material into the holes via negative air pressure (ie. slight vacuum). The larger holes below are exhausts - don't need to worry about those, they don't collect gunk buildup because they blow air out. - the vacuum effect is not too big of a problem, by the way - the intake vent hole vacuum isn't that strong. You could go 3 heavy runs without the vents getting too clogged - just depends on the nature of the runs. Just have to keep an eye on it, and have to consider running a wirebrush over it before every run - that's a good and easy maintenance. - the motor on this unit is down at the end of the pole, for that reason you might want to STICK TO DRY CONDITIONS with this unit - DO NOT WASH the head of the unit with water - use a wire brush - avoid sweeping the tool deep in bunches or piles of cuttings or other material (such as grass you just cut, where you want to make a 2nd, lower sweep to cut farther down) - that is a source of the "gunk" that can get in the vent holes. - combining the logic of some advice above: EVENING HOURS when its both dry and cooler are the best times to make runs. - as you would expect, this brushless motor can BURN OUT if you really push it. --- take some breaks especially during the hottest days --- don't just swap 5AH batteries in back-to-back without letting that motor cool off some --- sometimes the batteries get hot, and will prevent the unit from running - THATS GOOD (if annoying sometimes) - now listen: we can prevent the battery from making this decision by simply holding the trigger for a long time. THATS BAD, DONT DO THAT. LET THE UNIT REST. If the battery does this, and you feel like the motor shouldn't be running too hot (ie. you've been keeping gunk from the vent holes, ambient temp is avg or low, etc), then *maybe* it's an OK time to swap batteries just for a bit so you can keep working - the batteries do heat up faster than the motor. EDIT: I read that the motor also has heat sensors which will prevent the unit from running. In that case, it seems the point stands: - *Do* regularly let off the trigger to see if the unit wants to take a break. - just saying it one last time... It seems very important that the vent holes remain unobstructed by gunk, to help the motor stay cool. - It also seems that operators in more humid climates should take extra care, because very dry material, or conditions, won't lead to "gunking up" in the vent holes as deleteriously - although, plants generally are wet when cut. Apply discretion. - Dewalt probably wouldn't recommend this, but after maybe 1y of solid use, you might open it up to get Qtips farther in and keep the passageways unobstructed. Note: start unscrewing from the head back - the neck doesn't need unscrewed. - dont forget the high/low setting. Low will generate less heat, and low does great work when set against "easier targets". On the same token, if you use low against heavier targets, you'll end up running longer trying to wear the targets down, and it'll make more of a mess which means more gunk to obstruct the vent holes, and negate the efficiency of using low - so HIGH is better against those targets. EDIT: I've been just running on "low" lately with the new unit, and using dewalt's own .08 string .. why did I ever do anything different? Just run on low with their .08 string, it works great. The string is small and "cuts". - going to recommend sticking with dewalt's advice to only run their .08 line - that is what it is designed for and the longevity of the motor should take priority over the reasoning for using different string - not 100% sure on this, but I imagine (and from experience it does seem like) allowing the string out more often toward the 14" radius will help with many of the points above. The string travels at a higher MPH out farther from the head, cuts better, and the cuts are creating gunk at more of a distance from the motor. So that sounds like win-win right? I suppose so. EDIT: the string length does make the motor work a lil harder. Apply your own discretion. My situation: I let the head's vent holes get a bit cloggy and now I'm back to buy a 2nd unit (because I like this product so much). Basically I burned the motor out by running on high setting for 2 entire 5AH charges back-to-back (yes, I violated all my tips above) and it just died and wont start now. Dewalt does offer a "fixed in $79" guarantee via their website, but I figure after taxes and buying packing and everything I'd be out $110. So why not pay the extra $50 and get a brand new one. Won't be making the same mistake again. Might also be more careful about banging it to draw the string out ... don't want to bang it too hard - that trimmer head has electrical board & wiring in it! Not that I ever abused the unit too much ... or so I thought. Anyway, $160 for 1.5y of using this unit, for how light and convenient it is, and how quiet it is, and considering how much I used it, and the heavy jobs I set it on ... I'm too enamored to go without it, and getting a replacement.

Tool works great and cuts through grass well on the LO speed setting. I've covered about 1,000 square feet of grass on the first day and it works great! I've only had to use the HI speed on tough grass. This trimmer also eats through batteries like no ones business, and I definitely recommend buying the tool and battery combo, with the proper XR battery. I drained two four amp hour and one two amp hour normal 20 volt Max batteries before I ran out of the 20 feet of trimmer line, so I definitely recommend the XR battery or the new Powerpack for this trimmer for long hard jobs! Overall, amazing tool, and lighter then my old gasoline trimmer, I can use this all day... apart from battery swaps.

The DEWALT 20V MAX XR String Trimmer (14-Inch) exceeded my expectations from the first use. It’s lightweight, well-balanced, and very comfortable to handle, making yard work noticeably easier. The 14-inch cutting swath is the perfect size — wide enough to get the job done quickly without feeling bulky. What really stands out is the power. This trimmer has no problem cutting through thick grass and overgrown areas, and the variable-speed trigger provides excellent control when working around delicate spots. Battery life is impressive as well — I was able to finish my yard without swapping packs, and I love that it works with other DeWALT 20V tools I already own. Build quality is exactly what you’d expect from DeWALT: solid, durable, and dependable. Overall, this is a fantastic cordless trimmer that delivers performance on par with gas without the noise or maintenance. Highly recommended for anyone looking to upgrade their lawn care setup!

I believe Dewalt got the quality aspect pretty good with this trimmer. It’s heavy, solid, and has tons of power. It could go head to head with my Echo trimmer and not disappoint. However, the hinge joint is in the absolute worst location, because that’s the exact spot the handle needs to be. And I fail to see why Dewalt believes having a foldable trimmer is such a necessity in the first place. Seriously, who doesn’t have space to store this unless it’s folded? The greater inconvenience is having to put the handle in a place that makes this trimmer unbalanced and harder to handle. Your choice is to attach the handle either above or below the joint, neither of which is ideal. Don’t get me wrong, I like the trimmer ok, but my back gets tired more quickly with this one compared to my Echo, due to the awkward handle placement. I like just grabbing this and trimming without gassing up and starting the other one. And a 5ah battery makes it last longer than I need. The bump head works ok. It’s a little sensitive and will dispense string at times I don’t intend to. I think it will last as long as you occasionally blow compressed air through the motor vents to clear dirt and grass cuttings. Dewalt: “Ditch the hinge”.

Great battery powered weed trimmer. Bought this unit as I already own the DeWalt Batteries. It arrived well packaged. Very light assembly to use it, just attatch the handle and the guard with a few screws. Only used it once and pretty light stuff but it ran well and seems like it would still cut through heavier weeds as well. Folds up for easier storage but still has a long reach when using it. Built solid. One minor thing it is a little hard to open and close, hoping it gets easier with a little more use.
