20 Most Recent Dewalt DC988ka 18 - volt XRP 1/2'' hammerdrill/drill/driver kit Questions & Answers


The switch pretty much has to be stuck/shorted. Does it do it in reverse also?

Here's what you're looking at for possible parts:
Motor and Pinion PN: 396505-22SV $40
Brush and Holder PN: 603754-01 $6 (ea)
VSR Switch PN: 152274-22 $55
Depending on where you buy, plus shipping. Any or all of the above parts could have caused the drill to get hot enough to make a burning smell. You'll have to take it apart to see what's wrong then assess the repair cost vs. buying new.

The switch on these drills is notorious for doing exactly what you describe. One thing to check is the battery terminals on the bottom of the switch, they get bent or broken off easily. It could also be internal to the switch but the only fix is to replace it. You need Dewalt part number 152274-22 to repair the drill. It's a fairly easy repair but shop the internet, they cost from $55 to $75 plus shipping.

It all depends on what is burning I'm afraid. When in use, run your hand around the back of the machine and handle area to see if anywhere in particular is getting hot. On the older versions of these (DW988) the leads leading from the switch to the brush holders would overheat and burn, also causing damage to the brush holders themselves. Is there any smoke coming from the rear vents, if so you wil probably find it is a motor problem and the smell would be the insulation burning off the armature. The only other thing to check would be to make sure the battery isn't shorting and getting hot, as this could also cause damage to the switch and vice versa.

if your batts are ok and the batt connection terminals look ok you may have either faulty switch burnt off wire at brushholder or reqire new brushes

if the chuck is rusted start with some WD-40 on the chuck body. Then what I would do is take a rag and wrap around the chuck collar and using a pair of channel locks grip the collar with enough pressure to hold but not break it and using the tool in the low position pull the trigger switch SLOWLY and see if that doesn't free up the chuck. Let me know if still stuck and I will come up with something else, but this usually works for me.

go to Dewaltservicenet.com and type in your model number and you will find a schematic on this tool that will help in the reassembly.

If you noticed this sound the first time you tried the drill, it is noise of the armature brake.  This noise is normal and not a problem at all.  Michael Mittelsdorf

You can try warranty services. However, if they are having an event in your area you might just try going down there. I have taken bad batteries to them in the past and they just GAVE me a new one.

OPEN CHUCK FULLY AND LOOK INSIDE , THERE IS A SC REW YOU NEED TO REMOVE USUALLY A LEFT HAND THREADED ONE

What kind of batteries are they? If they are NiMh and haven't been used for a while, they can lose their charge and NOT be sble to be charged again!

Do you have a 3rd battery that does work? Buy a battery to make sure the charger is working or that the drill is working. If yes to both of these, then your old batteries are NFG.

As far as a schematic goes, I would guess that it is proprietary in nature and that not even dewalt "repairs" them. I wouldn't be at all surprised if the same model had several different versions of circuit boards representing different production runs
