## Questions & Answers

**Q: Does anybody know how to stop the line from feeding out all by itself? its only my third time using it with the factory line.**
A: This trimmer is meant to be self feeding, but it should only be feeding out line as you need it.  If it is feeding out more than that, I would check the spool to make sure it and the spring loaded cap are both installed correctly  I ususally have the opposite problem, where after extended use, the line heats up and doesn't want to feed out, but it is easily corrected by removing the cap and adjusting the spool. Were you using something other than factory line before?

**Q: does it really auto feed reliably**
A: Sometimes it doesn't feed properly, but most of the time the line feeds properly so you can keep on working.  My experience is that when the line gets pulled really tight the line welds itself to the spooled line and you have to pull that apart.  IHMO, overall it is the best trimmer I ever used.  I like the single line as the double lines seem to use up a lot of line and you're constantly changing the spool.  It is hard to find in the local stores, so I've order a couple (over the past few years) from Amazon.

**Q: I am wondering how you turn this upside down to do curbs.?Upside down does not give you the correct way to handle the trimmer?**
A: The guard is supposed to come off an be repositioned on most models, but I found this to be too much trouble, and I just hold it the wrong way and edge that way... but if you find it too uncomfortable, or have a lot of edging to do, try repositioning the black string guard and see if that helps.

**Q: And this IS a single line trimmer?  Had a single line earlier, loved it. Had to buy another, got a double line, DO NOT like it!**
A: Yep, single line.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Update:  Season 4  -  All Is Great!  I'm ordering another.
*by E***2 on September 9, 2012*

September 2012 - After reading many of the reviews, I was hesitant to purchase this item. I started out with the battery model for the B&D trimmer and after charging 24 hours it worked for 15 minutes top. I returned the battery model and purchased the electric B&D model. I used it for the first time today and was able to complete an hour's worth of weed-eating and edging work. I was thrilled. I am a 55 year old woman and I find this trimmer easy to handle (except for the cord, but I don't mind that if it lasts more than 15 minutes.), light weight and quite powerful. My yard is 70' x 125' and I was able to complete almost all of the edging in a little over an hour. (I stopped because I needed a break, not because the trimmer lost power.)I also used all of the initial string and had to restring the trimmer with 0.065 string. This is usually my biggest test because I can never get the string on right. I followed all of the intructions and reloaded the string and was able to trim for another hour without fail. I hope and pray this trimmer continues to work. Will keep you all posted. EBApril 2013 - Season II - All is great. Today was our first real spring in Richmond, VA -- 90 degrees -- more like a shift from Winter to Summer instead of Spring. Anyway, I pulled the old B&D Electric Trimmer I purchased last year with my fingers crossed and to my surprise, it worked like a champ. I edged for over an hour --- that's my personal limit --- and all was fine. I must say, it is a lot better than the battery operated model. I changed the string with not problem and I didn't have any string problem until the end. I still have half of the yard to finish tomorrow, so stay tuned. If it gets me pass the more demanding part of the season, I'll give it a 5 Star because the first Spring cut after Winter is the worst. I was anxious but all worked just fine!August 2013 - Great Trimmer! I am going to order another just in case.May 2015 - Spring cleaning and lots of edging....Trimmer worked like a PRO! Trimmed 8750 sq/ft lawn plus flower beds. Worked continuously for 1.5 hours --- when I needed a break. All works well. I'm impressed and I'm ordering a new one today to keep on hand. Five years of heavy use is not bad.

### ⭐⭐⭐⭐⭐ So far It Has Been A Great Trimmer!
*by J***A on January 20, 2016*

This is by far the best trimmer I've owned in a long time. I've used it 5 times now to trim and edge my yard, and I haven't had a broken line yet, and it feed remarkably well. I am still using the line that was supplied on the spool, and that might be the reason it has performed so well. When it comes time to replenish the line to the spool, I'm going to try ensure that it is wrapped neatly. I think the real test will be on the replenished spool. So the jury is still out on that. But so far it has earned it's 5 star rating. Well done Black and Decker. And no....... I'm not one of those paid reviewers.**********************************************Review Update**********************************************Have been using this trimmer since Nov2015. If I could, I would give it TEN STARS ! This is by far the best trimmer I've had the pleasure of using, and I've used a lot of them. Am sorry to admit I have wrapped a few around the trunks of large sturdy trees in desperation. I've never once had to hassle with broken lines or failure to feed, and I'm working on my 3rd spool of line, 2 of which I wrapped. Everything eventually wears out, so I'm debating on buying another ST7700, for a spare. You never know when B & D will decide to change the model, and possibly not get it right the next time.

### ⭐⭐⭐⭐⭐ Exactly what I needed
*by N***R on May 24, 2015*

This is a great price for a great weed whacker. I just got it yesterday, but I've already done my entire front and back yards and they look fantastic! It is very easy to use and not too heavy. The automatic string feeder makes using this item so simple anyone could do it. Also you can twist the handle so that it can edge sidewalks and patios. It's really easy to switch back and forth and it leaves a clean edge all around. Everything looks amazing. Also it has a cord keeper where you can loop the extension cord (not included) so that it doesn't unplug when you're using it. The only drawback at all is that the spool isn't very big and they're not super cheap. I got almost the entire yard done but ran out. I hadn't bought additional spools from Amazon but Lowe's carries them for a comparable price, so they're easy to find. All in all I'm thrilled with this and I highly recommend it to anyone! I love that it is electric and doesn't require gas, too.
