However, you will still need to keep track of the maintenance and the basic functionality to get the drill working perfectly.

So, if the drill is not hammering, you will need to make sure that you are getting it done right, and a few such things to take care of are:

  1. Check the Battery

The problem is most of the time faced due to some of the problems with the battery if you are using a cordless hammer drill from DeWalt.

That is why you will need to ensure that you are getting the perfection on the drill, and with all that in perspective, you will need to check the battery health first on your cordless DeWalt Hammer Drill.

So, you will need to check the DeWalt hammer drill batteries for battery health first.

Afterward, you will also need to ensure that the batteries are properly charged to get you the right experience with hammer drill hammering at the same time.

Nine times out of ten, the issue will be fixed right here, and you will not have to bother with more errors on your end.

It all comes down to how you’re planning on adjusting the setup, and going through with these pointers will save you a ton of time and effort.

This is especially true for owners that have been using the drill for years. So, if you’ve had to replace the battery up to this point as well, now might be a good time to do so.

The new battery will not be that expensive, and you will be able to accommodate that purchase easily.

  1. Check the Fuses

The next thing that you will need to check if the hammer drill is not hammering is the fuses. Some of the fuses might have been blown, or they might not have been connected properly.

That is why you will need to make sure that you inspect all such fuses in the right manner.

You will need to inspect each of these fuses properly, and if you find any of them to be blown, it would be great to have them replaced properly.

That should be the best thing for you to make it work properly for any of the needs that you might have been having.

  1. Check the Carbon Brushes

Another thing that you will need to be particularly careful about is the carbon brushes that you get on the Drill hammer from DeWalt.

These carbon brushes are wearable components that will cause you some issues if they are worn out.

That is why you will need to ensure that you are checking on these carbon brushes, and if they are worn out, you will need to have them replaced and the motor cleaned out properly in order to not face these problems again.

  1. Service The Unit

Sometimes, all it takes to fix the situation is to service the unit. We can’t stress the importance of the maintenance cycles enough, and you will have to make sure that the system is perfectly clean and functional.

Otherwise, you will just be running into more errors down the road. All that you need to do here is to first wipe away the grime from the unit and then blast it with compressed air.


That will be more than enough to help you get rid of the lodged debris, and you can go about managing the system accordingly.

After fixing the situation with the grime and the dust, you need to also lubricate the pivot points. It all comes down to making the movement easier for the unit, and there aren’t that many options left.

So, you will have to make sure that the device is allowed to move easily as you’re trying to adjust the system. 

One mistake that owners make regarding the lubrication side of things is that they will use grease to lube up the system.

This is not a good idea as the grease can combine with the dust particle and promote grime that will then solidify on the pivot points.

So, instead of going cheap on the lube, you need to expand your options and only rely on the established options in the market.


That will not only help you get a better performance out of the unit, but you will also notice a more robust and consistent response from the device.

After the lube has been applied and the system has been managed properly, you can go about resupplying the power by connecting the battery

From there, you can test out the unit one more time, and the hammering features should work. 

Hopefully, all errors will be addressed right here, and you will not have to bother with the same complications again. 

  1. Try Using New O Rings

In some models, the fix is more related to the worn O rings, and you will have to replace these rings to get through the fix.

Now, it might seem like a complicated idea to manage the replacement, but the process is fairly simple.

All that you have to do is to access the piston from the cylinder and then remove the O ring as well as the piston ring from the back.

From there, you can install the new O ring and then go about adjusting the unit accordingly.


The best thing here is that getting new O rings will not damage your budget, and you will notice a huge jump in the performance of the hammer drill.

So, be sure to keep all of these pointers in mind when you can’t seem to secure any response out of the unit.

Hopefully, you will not have to bother with any extensive errors when setting up the unit and managing the O rings. 

  1. Get it Checked

Lastly, if nothing so far has worked out for you, and you are still facing the issue on your DeWalt hammer drill, you should be getting it checked and fixed up properly since there can be some other major problem on it that will need to be sorted out.


That is why a DeWalt authorized technician will be able to sort out the issue for you and have it fixed up properly as well.

This is especially true for owners that have recently purchased the unit. The warranty deal behind this device will cover all damages.

It is not that rare for power tools to get damaged during delivery, even with all of the extra padding and bubble wrap.

So, you will have to make sure that there are no cracks in the system, and you can reach out to the dealer about these issues.

If the issue is genuine, and you’re not to blame here, getting the new unit will not be that difficult. All that you will need to do is to forward a warranty claim and then demand a new piece.

The DeWalt dealer will verify your purchase and then dispatch a new unit within the same week. 

Wrapping Up

Can’t seem to make use of the hammering features from your DeWalt hammer drill? Going with the pointers listed here will help you get the ideal performance.

You will not feel the need to upgrade for years when making use of this drill as long as you keep it fully maintained.

On the other hand, ignoring the maintenance will only lead to more issues with the system. So, be sure to keep all of these pointers in mind when you’re aiming to get a decent response from the unit.

Hopefully, you will not be disappointed with these pointers, and the unit will fit your needs perfectly.

Next, you need to also check up on the hardware side of things as well. We all know that the situation around the workshop can become a bit rough.

In these situations, it is not the easiest job to keep the unit free from water and impact damage.

So, if the hardware is in rough shape and you’re not sure about the wiring side of things, just ask an expert for help.

There is nothing that you can do to fix a damaged unit yourself, and you will have to reach out to the dealer. Hopefully, that will be it, and you will not have to bother with the system again.
