A strange yet common problem that you might have to face with the Milwaukee M12 Multi-Tool is certainly something that you will need to be careful about. Suppose you have the batteries installed properly, and you put a bit of strain on the oscillating tool.

In that case, the batteries will be ejected out automatically, and that is certainly something that you will need to be careful about since it might be causing you to have a number of issues that you wouldn’t want and will definitely be causing delays and hindrance in work due to breaks.

That often has to do with the battery holding parts, and the vibrations can cause the battery to be ejected out. That is why using some adhesive should help you to solve this problem optimally, and you will not have to face any such problems after that.

It would be better to charge the batteries carefully while they are installed on the tool through a proper charger and avoid taking them out frequently, and that should help you to avoid any such problems in the first place.

  1. Excessive Noise

Another common issue that you might have to encounter while you are using it is to get excessive noise due to the vibrations and more, and that is certainly something to be careful about since that doesn’t only cause you to have an inconvenience but can grow and cause you to have certain problems later

These problems include the internal breaking of the parts or, at times, the grinding on the gears as well, which will cause the gears to wear out and cause skipping.

That is why you will need to make sure that you are not having any such issues with excessive noise. The problem is often caused due to some loose parts or lack of lubrication, and you will need to tighten up the screws and all the components.


After that, you will also need to take care of the lubrication optimally. That will help you out to sort all such issues, and after that, you will not have to face any such problems with excessive noise on the tool.

  1. Not Holding Charger

Next, the tool can stop holding the charge, and no matter how long you charge it, you will be facing different sorts of problems, like the battery getting discharged on its own or something like that.

That problem is usually caused due to the charger being faulty, and you can easily have it fixed up by trying to replace the charger, and that should help you out optimally.

If the charger is not faulty, and you are still having a problem with another charger, you will need to replace your battery, and that should help you to ensure that you are not facing any such problem afterward on the tool.

  1. Unit Won’t Engage

The situation with the tool not working can be a bit serious at times, and you need to first look at the response from the LED indicators. If you can’t get any response, then there might be issues with the battery not supplying the unit with enough power.

All that you have to do here is to check up on the power status of the battery and then leave it out to charge for a few more hours.

That will do the trick, and then you can connect a charged battery to the unit. Ideally, you will be sorted at this point and will not have to deal with any extensive errors.

However, if you’re still stuck in the same issue and can’t seem to get any response out of the unit, then you’re dealing with a defective battery or wiring system. First, you can try to check the situation with the battery by using a voltmeter.

If the battery is fine, you can move forward to check the situation with the wiring side of things.

Here, you will need to disassemble the system and then check up on the wiring connections. If the wiring is not in good shape, you will have to get some new wires here. 

So, be sure to keep all of these pointers in mind when you can’t seem to get a good response out of the system.

It all comes down to how you’re planning on adjusting the situation and following through south. These pointers will have you sorted. Otherwise, you can always reach out to official support.

  1. Gear Issues


The situation with the gear can also get a bit complicated over time, where you’ll struggle to secure a good enough response out of the system.

The good thing here is that the noise cues will help you stay ahead of the situations with the grinding gears, and you will be able to fix it up accordingly.

So, if you’ve been putting too much load on the system for the past few months, and the response from this multi-tool is not optimal, then it might be a good idea to check up on the gears.

All that you’re trying to do here is to adjust the alignment or replace them entirely.

It all comes down to the hardware status of the unit. If the gears are in poor shape, then your hands are pretty much tied. There is not much that you can do about the issue, and you will have to get new gear to install in the system.

Luckily, the purchase of new gear will not be heavy on your budget, and you can stick to a limited budget while trying to proceed with the upgrade. From there, you can also check up on the alignment side of things. 

This is especially true if you don’t think the gears are worn out or ground.

So, all that you need to focus on is fixing the alignment and making sure that all of the gear teeth are making tight connections. It will take a bit of trial and error, but you’ll surely be able to fix the situation easily.

  1. Overheating Complications


While every tool on the market will overheat when you’re going through a demanding project, it is a concern when you can’t get through a simple job with the unit.

This is especially true if the heat from the unit hinders the performance of the tool.

So, you’ll have to check up on the lubrication side of things to get a good enough response. All that you’re trying to do here is use some decent lube on the connection points and then check up on the response from the system one more time.

Many owners make the mistake of using grease, and that will mix up with dust to create grime.

So, you need to avoid the use of grease and rely on some decent lubricants from the market to adjust the situation. It will take a bit of time, but you will surely get a decent enough response.

Once the pivot points are greased up, you can also try to limit the load on the unit and make sure that you’re storing the device properly. Otherwise, you will struggle to get a response out of the unit, and it will keep running into more errors down the road. 

Wrapping Up

Planning on purchasing the Milwaukee M12 Multi-tool? Here is a list of issues that you can potentially run into while using this system. These issues might not seem that serious, but they sure are annoying to handle.

So, the only way for you to avoid these issues is to keep the unit maintained. Missing maintenance cycles or storing the unit improperly will only lead to more errors down the road.
