Q:The Edger, I'm not sure why this is combined with the pole saw, anyway it says the blade can be beveled. Can you dig a small trench with it and if so how deep? Thanks
by|Apr 6, 2024
1 Answer
Answer This Question

A:  Hi Brian! The Edger is designed for edging along hard surfaces, such as sidewalks, driveways, flower beds, curbs, and similar areas. It does feature an adjustable depth of cut and can be increased until the desired cut it achieved. - Milwaukee Tool Social Team

          M18 string trimmer, melted terminal.
          I love the trimmer itself, but it has melted my battery negative terminal, its melted on the trimmer and battery terminal. Other than that flaw the trimmer works wonders and i love the veriable speed, as well as the smooth trimmer feed.

          I immediately started using this. I have two limbs as big as trees down. This thing is awesome. Not one hiccup yet. Battery lasted longer than I thought. Would buy again!

          So much better than I could have expected
          So, we just went through a crazy windstorm that ruined the Portland, OR area We had a tree split in half and crash in our yard. Go figure I was able to slice through everything with the 10"Mikwakuee pole chainsaw. Electric is so effortless. I took down a 12" section of tree with minimal effort on the saw or me. I just purchased the Milwaukee 16" saw for going forward. If the pole saw can take apart what I just did with it and leave with three bars of power, I'm sold.

            Why in the world do I have this tool?
            I purchased this kit just for the free blower. I figured I would sell off the string trimmer, battery and charger. That was the plan, but then one day, I cracked open the box, and I actually started using the string trimmer and it made me feel powerful. Like Tony, Montana or Arnold Schwarzenegger! Plus the blower is awesome, so many different uses for the blower and they make it easy because there is No gas,oil or any of that stuff.

              Battery and tool damage if used under heavy load
              I use this trimmer to trim grass and weeds. The problem with this trimmer is that if you cut high or dense grass and weeds for 5 minutes or so the battery overheats and it shuts off. This is actually expected behavior and a safety feature. However, the contacts for the battery get extremely hot and the plastic around the contacts in both the battery and the tool have melted. This has occurred with two batteries that I have used with it. Last time I used it the battery housing melted to the point where I needed a pry bar to remove it because the melted plastic on the battery hit the tool body and caused it to jam. This is very disappointing from Milwaukee since according to their product description this is designed for use by professional landscapers. I doubt this type of problem would be tolerated by anyone who uses this tool to make a living. This is a poor design, materials capable of tolerating much higher heat should have been specified around the battery contact area for both the battery and tool.

                Tool melts battery terminals
                I am happy with the operation of the unit overall, but it has melted the negative contact on my XC8.0 battery pack. I have seen many reports of this problem.
