looks like a new unit purchased within last 2-3 years, best to send back to manufacturer for repair and possible replacement under warranty if avaialble

Take a look at this diagram. Items 14 and 15 are the wires that run from the switch to the motor. They tend to get hot and melt the insulation of the wire where the connector plugs into the motor. If the bare wire touches the metal motor housing then it will short out. I would guess that is what happened.

spray a break free oil down there let set over nite or hold chuck w/ channel locks

Hi, soak the chuck in crc overnight then put the drill in low speed and reverse. Hold the chuck by hand or with multi grips and pull the trigger. Hope this helps, regards Phil.

It could be but more likely the motor itself is just worn out. I would replace the motor assembly as they do wear out on these models. Here is a link to the parts diagram.

It is a keyless chuck. You should be able to grab the main body of the chuck and turn it to the left to release the bit. You can also hold the main body of the chuck and run the tool slowly in reverse whcih will also release the bit.

It is a keyless chuck. Put the drill in reverse (chuck should spin to the left when viewed from the back) and hold the main body area of the chuck with your hand while slowly running the drill. The chuck will open (unless it is broke) and release the bit. You do the opposite (slowing running the drill in forward) for tightening a bit in the chuck.

open up the jaws ,look in the now open area there is a standard screw at the base remove it chuck will come off ,,some are stubborn,,

i would imagine its the trigger or battery conections on the drill. How much for it lol

on the charger there is a red LED that blinks while it is charging when it is fully charged it will not blink usually about 1 hour to charge a DeWalt 18v battery

reverse the direction of the drill hold the chuck and press the triger

Hi, Take the drill apart using a star driver. When taking the chuck assembly from the yellow section have the drill chuch down to stop bits falling out. Once handle is apart popout the triggger assembly. Remove the two power leads from the assembly. Try a direct connection to the battery (polarity doesn't matter. If the motor goes it means that the trigger is U/S. Put a tester across the terminals (either set). You may have a short (as I had). It appears to me that the trigger is not user servicable. I used one from a DeWalt recip saw with a mod on the reverse lever. Works well.

Good luck.

if you have it clamped nice and tight it should no way do this. unless the handle is hitting the chuck.

I suggest that you check the brushes, and the armature. Worn out brushes sometimes cause that condition.

Also, try different trigger settings, to eliminate that as an issue.

check the screw in the center of the chuck it could have come loose causing it not to lock properly.

That is your torque, if you put it at 1 is runs slower but puts more power into it if you put it on 2 it runs faster but less power. I usually start with 2 and if it won't drive it in all the way put it on 1. Good Luck

Repair kits are available at Grainger stores and from the Mfg. on line.

drill chucks are pressed in, and beveled. The way I found is to open the chuck and tighten it around something like a lag bolt that is firmly secured to something like a bench top, I use the telephone pole outside my garage. After secured tight, give the drill a few raps with a rubber mallet, its in there tight but will come out.
