But sadly, people face with Milwaukee string trimmer problems every now and then.
We will discuss those problems including the identification and troubleshooting process. Stick around with us to learn some easy fixes!
Common Problem With Milwaukee String Trimmer
Irrespective of brands, string trimmer got some problems. That’s why people look for string trimmer alternatives.
However, here is a list of some common issues and complaints:
- Stalling & sudden shutdown problem
- Overheating issue
- Trouble with trimmer lines
- Short battery life
- And some more…
Every flow has its ebb. Milwaukee string trimmer, similarly, as mentioned above, can pose some problems that can be solved easily.
Let us first dive into the series of problems one might encounter while using the Milwaukee string trimmer.
- Starts But Stalls
This problem might be a combined result of the overheating and batteries issue. This Milwaukee string trimmer problem happens when the motor inside starts to overheat, resulting in reduced performance.
Does this list of problem identification seem unending? Worried that your string trimmer problems might not have a solution?
Fret not, as we got your back!
- Overheating Issue
When used for a long time nonstop, the Milwaukee string trimmer starts to heat up from within. If this continues, the trimmer battery will melt only after a month’s usage.
- Trimmer lines Troubles
Each Milwaukee trimmer has a different line size ability that it can take. Thus, treating Milwaukee string trimmers like others will be a blunder.
Here, you do not have the option of simply threading the line and twisting its bump mechanism. Instead, you have to take the spool out and wind its trimmer line manually.
If you are among one of the strugglers of the trimmer line issues, stay put. We will tell you how to do this in a jiffy!
- Short Battery Life
The battery issue is not that common. It only happens when you have to trim huge swathes. Alternatively, this might happen when you have to run your string trimmer for long periods.
- Two types of speed
Milwaukee’s low speed is absolutely compatible when you need to cut through a thin layer of grass. With its battery life, the string trimmer allows low trimming effectively.
Likewise, the high speed works well for the overgrown grass. However, both speeds on a single model seem redundant to many users.
Users feel they are paying more than what they need.
Solutions For Milwaukee String Trimmer Problem
Now, moving on to the most anticipated section – the quick fixes!
Below are some of the methods you can employ to fix your Milwaukee string trimmer issues. So, without any further delay, let’s dig in!
- Speed Control Solution
Milwaukee has some old models with just one type of speed. If any user has a preferred speed choice, those string trimmers are just the perfect fit!
- Milwaukee String Trimmer overheating problem fix
Still, Milwaukee has not introduced any special overheat protection. As there are really rare cases of overheating, the brand has not considered some fixing.
However, you could try giving the string trimmer a breather during long hours of operation.
For security purposes, keep using the 9 and 12 AH batteries, which will keep them from melting.
Another wise move would be to run this tool on low-speed settings. This helps to reduce vibrations. In return, this will prevent the tool from heating up.
Lastly, try placing a small insulated computer fan that directs airflow to cool down the motor driver power supply.
- Replace the Trimmer Line
At first, turn over the trimmer head and take off the spool by pushing in your taps. Then, drag the cover away from the spool housing.
Next, take 3 wingspans of line and cut it. When you fold the line in half, the centre will be visible. Loop this through the notch in the spool’s centre rib.
Finally, wind both the bottom and top tracks in the same direction. When you reach the end of the trimmer line, secure the reminder in the top notches.
After lining up the spool and the cover, push the spool in it. Finally, you will be set to grind!
- Extra Batteries
For the battery issue, we can only suggest you use an extra battery set. Otherwise, you can give the trimmer some cooling time.
- Resolve the Sudden Shutdown Issue
Rest assured if your Milwaukee string trimmer shuts down after a while, for we have come up with some of the best fixes.
- First, check your motor driver’s power supply using gloves. If it is hot, let it cool down. Then, wait for a few minutes to see if the temperature falls. If not, try installing a small computer fan.
- Your second option would be to change the batteries. Place a new collection of batteries to see if they work.
- Examine the spark arrestor. The string trimmer engine stalls when your spark arrestor becomes clogged. After removing it, clean the spark arrestor with a brush. You can also consider replacing it.
- See if you have a clogged carburetor, which happens if you leave fuel in your tool for a long period. Clean it using a carburetor cleaner. If it doesn’t improve, replace or rebuild the part.
Milwaukee String Trimmer: Should You Still Have It?
A battery-powered outdoor power tool for weeding and trimming grass is known as a Milwaukee string trimmer. It can mow grass in places that are difficult to reach using a lawnmower.
One wonderful feature of Milwaukee string trimmer is that you can pair it with different attachments to complete various chores.
So, it can also be used to trim difficult-to-reach areas like tall hedges. The instrument is called by several names worldwide, but they all point to the same thing eventually.
The string trimmer’s cutting head employs a microfilament string that spins quickly to provide the energy needed to cut.
A motor-driven shaft extends all the way to its cutting head, providing the necessary drive to rotate the microfilament string.
The line becomes strained and stiff after the string reaches its maximum speed. However, it can cut most sorts of soft plant materials because of the inertia created.
Now that you are acquainted with it, I strongly recommend having this in your arsenal.

I am happy with my String Trimmer, however I am also experiencing battery casing melt with 6 and 8 AH batteries. I will start limiting the time I run the machine when in use and use a fan to help cool it down while waiting. I hope there is a fix soon.
milwalkee line trimmer is absolute rubbish, works fine for 10 minutes then keeps shutting down I believe is overheating issues. I am not overworking the unit I believe it is a manufacture fault that milwaukee are trying to ignore but many people are finding the exact same thing.
Ours is battery operated and after a few minutes stops working. It is not the battery as we have tried multiple. I am beyond frustrated because this is what I use to weed eat when the husband uses a gas one. Plus, with the cost of the weed eater I am disheartened by Milwaukee because the battery skillsaw we purchased has already been sent back once and has no stopped working again. My husband used to praise Milwaukee but I am starting to think they suck.
Installing a computer fan?
Why not an ice tray?
Just bought the Milwaukee string trimmer to go with my Milwaukee chain saw. Both battery operated. No problems with chain saw. Stops when charge is used up. Maybe about an hour. Power sprocket has material build up behind it. Needs to be cleaned occasionally, and chain tightened. Leaks oil. Always check.
Weed eater works well. Used about 6 hours total so far, no problems. Batteries I switch between the two units are 8 and 9 amp. String changing is a snap, once I figured how to change it. See video, great help. These are so much better than gas powered. I am 79 and find them beyond convenient.
I bought the Milwaukee string trimmer and liked it so much that I bought a second one. Unfortunately, the second one has a bad vibration when in use. I’ve tried swapping the attachments and there’s definitely some sort of vibration in the new trimmers motor housing.
My Milwaukee trimmer works great for what i have to do. Problem is that shortly after i run it one of the two strings breaks inside the hub?? This has happened the last three times that i have used it. I replaced the strings with a Milwaukee string. The same problem occurs. Once it breaks off it take the hub apart and re string it per the instructions or i just use one string. The new string is brand new. What is necessary for this breaking to stop
I recently acquired a Milwaukee string trimmer but I think I’m missing a piece to connect the splines in the drive shaft
I have tons of Milwaukee tools m12-m18 this trimmer is the worst product they have. Brand new my wife came in after about 6-8 min of using it and said it keeps turning off. I tried it the next day at a small job I had. And it did the same thing to me. Definitely not over using it. I see so many other reviews that everyone is loving it. Not shure if there is just a bad batch out there. But for the $ this is a pos.
Purchased 2 Milwaukee string weed trimmer both shut off after about 10 minutes. Battery life not used up. What is my solution for this
I had my string trimmer rebuilt from the Milwaukee Authorised Service Center because it kept shutting off after a short time of using it. It lasted about 5 uses and now back to the same problem. I will use it for about 10 to 15 minutes and then it keeps shutting off. I’ve replaced the batteries with a fresh one but the same problem occurs. I think the string trimmer is the worst item that Millwaukee makes.
I have the milwaukee fuel quick lock stŕing trimmer… it works great for 5-10 minutes then overheats and stops working until it cools off…
I have the issue of shutting down also after a few minutes of use. Milwaukee replaced it, The problem continued until I started using.085 line. No more shutting down.
