Top 20 Dewalt DC920KA Heavy Duty Xrp 18V Cordless Drill/Driver - Page 6 Questions & Answers

Use a pipe wrench on it to give yourself a little more leverage. It is simply jammed all the way open and it will release when you apply enough force.

Hello Matt - I recommend that you get your drill to the nearest Dewalt service center. That way you know it will be done right and under warranty. Go to this site to find your closest dewalt service center:

The transmissions come as an assembled unit and there are no drawings for the internals. If you can find an old drill that is no good, use it as a guide.
Hope this helps

A TORX I believe , if it is a 6 point star type screw hole? They are measured in mm I think and 15 and 20 are the most common sizes.

Once you take the chuck off use somethine to the effects of brake cleaners, Wrap everything that you do not want to get the brake clean on and clean it and then let it sit for a few minutes then go ahead and oil everything and you will be good. Safe and effect way to do this especially if you have dirt or sand in the gears

Use a pipe wrench to give yourself a little added leverage.

The only time I have seen a persistant problem like this before is when there has been a slight defect in the housing or switch. It works ok for a while, and then gets a bit scored up and that is when it usually starts to stick. You could try a bit of emery cloth/fine glass paper on the housing area that the switch button slides through. Also, when cleaning, a good thing to use is brake/carb cleaner as it evapourates quickly and is generally non conductive. It will get rid of a lot of grease, but most switches have a small amount of grease inside to stop the contacts furring up, so always make sure you spray a bit of wd-40 or someting down the switch slider shaft afterwards.

This tool has key features and functions:
Variable Speed Shitch
Forward and reverse button
Torque adjustment ring for drilling and removing a wide array of fasteners
Three speed gearing 1 highest torque 2 niddle torque and speed setting 3 highest speed setting
It also has a hammer drill setting for use in masonry.
I would recommend if you do not have a manual going to the Dewalt website and downloading a complete manual so you can get all the use this tool has.

in drill mode slips will not tork

Normally you would use a masonry bit to drill into ceramics eg tiles or bricks. if the plate is glazed it is better to stick some masking tape or adhesive backed paper on the area to be drilled to stop the drill bit slipping around. also i would be inclined to use a hand turned drill or a small battery powered drill if you have one to avoid breakage of the plate.

i dont know where you live but if you can find a black and decker outlet they can usualy take care of the problem

You have burned out the drill motor, it is shorted, the battery smoked due to a direct short, one thing I don't understand why the thermal limiter didn't trip in battery pack, I would contact manufacturer and try to get hem to buy you a new drill.

How to remove the chuck

There are different types of battery, the old ni-cad (nickel cadium) batts lasted longer if you let them run right down before recharging them as they had a 'memory' which meant if you charged them from half life they wouldn't charge as much after a while. The new Ni-mh (nickel metal hydrate) and li-ion (lithium ion) batterys don't suffer from this problem so you can recharge them whenever you fancy. The li-on batts don't tend to run compleetely out of charge as when tehy have lost a certain amount of power they just stop anyway. If your batt has lost some life it is possible to get it re-formatted' in some cases by having it put on a battery discharge tester. This is a bit of kit that fully discharges a battery from full in a short space of time and measures it's capacity by timing it. Because it completely discharges and recharges teh batt acouple of times quickly it can someetimes reinvigourate the batt.
