My drill seems to be buirning out my batteries. i have four batteries that i use between my drill and my nail gun everytime i put teh battery in the drill there is a burning smell and now im down to my last bettery.

check and clean ram and guide and or debris

Sounds like either the battery is bad, or since one is new its possible the contacts in the gun are not making proper contact. Are you sure your charger is working as well ? If you have a volt meter check that the battery does have a charge on it.

firstly its always better to change both of the bands even if one is broken this always keeps the drive trim.all seems well clean all the contacts ie battery and gun (do not use any cleaning products this will cause grease)just wipe clean with paper towel.

YES. You have dirt and grime inside.Go to a Lowes or Home depot and look in the nail gun dept. Get a can of Paslode tool cleaner.( white aerosol can with orange and black label) $8 a can. While running tour drill,(over a sink or outside) spray it all inside aroud trigger and motor,turn in all directions and watch how much gunk will wash out. You'll be suprised at what a difference this will make and it will prolong the life of your tool. Works great on all battery powered tools and air tools ! I highly recommend it, but don't buy them out of it , leave some for me. I;m allmost out of it.

Could be that the driver is not returning to top of the cylinder. Easy test, when the gun miss fires, remove air line, with thin metal, insert thru nose and push driver up. Retest gun. If driver was down a bit then nails will not feed. Remove head and check that driver oring is making good seal, lubed, and is not too tight or bent. Also check that lower bumper is not cracked or missing pieces. Replace parts as needed. If driver was all the way up, clean rails and pusher assembly with wd40 and follow with good cleaning with air. If pusher and rails working properly, must be problem with bad batch of nails, slightly thicker or wider head not allowing nail to easily slide. Open nose latch and check that nails slide thru easily.

Hello,

You need to open the nail magazine and you just load one strip of nails at a time, then close the magazine. It will have a spring putting pressure on the nails, so it will have resistance on it and it will increase as you close it.

The oil gets dripped in the air hose connection on the gun before you connect the air. Make sure that this gun actually takes oil, some newer guns are oilless.

Hope this helps,Matt

Is it Nano li-ion? have you got another spare battery to double- check?
I experienced the same problem with 18V Dewalt nano li-ion battery. Was fully charged, came to work- Dead!!! I was lucky I had spare one, so then i was ok, but anyways had to buy a new one. Check on these things:
1. Battery is faulty. If u have any chances to ask someone who has the same gun (voltage is very important!!! has to be the same!!!- 12V battery to 12V gun, 14.4 to 14.4, 18 to 18 etc). Put your battery into that other gun. If You find the same problem that means your battery is dead.
2.Gun with battery contacts. If you 100% sure, that batterIES (check 2 batteries, or more) are OK, check bottom contacts where u put battery in, use WD40, or similar to clean them.
3. Least common Dewalt thing (Most common in Panasonic drills) is trigger contacts.
Basically i do not know what model is your dewalt, i was only talking in general, but there are no miracles- stopped working suddenly, and what u describe new, for instance my new drill dw727kd is less than 1 year old, i was too stuppid to open that battery myself to void warranty :(
AAAAHHH!!!!!! One more thing - If you have not tried to open these screws- check your nearest Dewalt authorised repair center- new NANO batteries have 2year warranty!

Your battery could say its good by just testing voltage,but when a load is put on it , its a different story. My dewalt batt. did the same thing I opened up the batt. case and there was 12 "C" sized batteries inside linked together with little metal strips. I bought 12 rechargeable "C" batts. and carefully drilled where the metal strips are soldered, changed out batt. and re solder. It's been over a year now and still drilling . Also you should do this one batt. at a time so you don't put one in the wrong order .

sounds like driver is bent or worn
