20 Most Recent Dewalt 7.2-18.0 Volt One Hour Charger - Page 8 Questions & Answers

Most hammer drills on battery from brand Dewalt have its serial number in one of the yellow shell parts its a build code of the shells only under the battery holder also the year of build date stands there too it have the same function, I myself have long wondered too, because some Dewalt tools have a real serialnumber is it not fully clear why there is sometimes not and sometimes a full number to find, i have asked that also on Stanley Dewalt in Belgium. Ser 030942 on this picture but i know maybe you see a clear yellow line in black on the information sticker where you think there should be placed the number and they forget you will find no real number but always you can use the 2 3number code with year of build in one of both shells under batteryholder .

there is a 3 position switch on it- set it to hammer only which is all the way to the left going clockwise- if its set to hammer only and is still spinning then it has malfunctioned and it has no user serviceable parts.
if you did take it apart you could just ask for whatever help you needed or contact an expect directly for immediate help
good luck

Using a pair of vice grips (with protection so as not to damage chuck) grip chuck and strike vice grips with a rubber mallet, undoing chuck.

Likely poor battery contact, but there could be other factors.

I would bring it to an authorized service center and ask for warranty - there are not individual replacement parts, all the electronics come as one assembly, and unfortunately the brushless controllers are very expensive making the tool not worth repairing.

Replace battery. Ni-cad batteries have a life cycle, yours is the end of its life. Upgrade to lithium, battery if your tool will accept it. cost more delivers more in performance than the price difference. I once had nicad tools and disposed of all them and went to better battery..

Please include as much information about the tool. Find the label which states the actual model number.

Some tools will state on the side of the tool that it is a DR175.

However, there may be several variations of the DR175.

On the label containing the serial number, there should be a product number which may read DR175-S which would allow someone with the variation to answer your question.

Good luck!

some batteries are bad from factory, you should exchange it for another and try again. Make sure the battery voltage and type (ie. lithium, Nickel Cadmium,etc.) match the charger. If not, you can buy most replacement batteries for older models on the internet. If a second battery doesn't work - it's the charger .

If this is a newer purchase, my newer Milwaukee flashes slow for the first two beats and then quickly while it reads the battery type and then shifts to the slow flashing charge light after it determines the type. this is because it is a smart-charger and can charge different types of batteries

faulty trigger switch suggest to clean the inner part of switch or insulate seized wire or renew faulty trigger stitch

Since the charger says that the battery is not faulty, but it does not charge the battery, then the charger is faulty. The same happened to my client. The dewalt chargers do have 1 year warranty.
