Question 5

the bit keeps falling out of my dewalt impact driver, the chuck feels loose. how do i fix it?

Accepted Answer

You're likely not inserting the bit correctly, or the quick-release chuck is worn. First, let's make sure you're installing it right. Before you do anything, place the forward/reverse button in the lock-off (center) position or remove the battery pack. Look at the chuck. It's a 1/4-inch hex quick-release type. It only accepts 1/4" (6.35 mm) hex accessories and 1" (25.4 mm) bit tips. Take your bit and push it firmly straight into the chuck until you hear and feel a solid click. The bit should now be locked in. To remove it, just grasp the bit and pull it firmly straight out. If that didn't work and the bit still falls out, the internal hog ring (the retaining spring inside the chuck) may be worn or damaged. Do not disassemble the tool yourself. This requires service by a qualified repair person using identical replacement parts. Heads up: Never modify the power tool or its chuck. Damage or personal injury could result.

Question 6

i got my dewalt drill wet, not soaked but some spray from rain. is it ruined? what should i do?

dewalt dcd771 chuck is stuck, won't tighten or loosen, how do i get my bit out?

Accepted Answer

The chuck likely seized due to debris or lack of lubrication. You need to lock the spindle. Set the forward/reverse control button to the center OFF position. Insert the chuck key or a large Allen wrench into the gear ring at the base of the chuck. With the spindle locked, grip the chuck sleeve with your other hand and turn it counter-clockwise to loosen. You may need to tap the key gently with a mallet to break initial corrosion. IF THAT DIDN'T WORK: The internal jaws may be jammed with metal chips. Try blowing compressed air into the chuck while rotating it. If it remains stuck, take it to an authorized service center. Do not disassemble the chuck yourself. HEADS UP: To prevent this, always clean the chuck threads and blow out debris after use. Check for misalignment or binding of moving parts as part of regular maintenance.

Question 10

dewalt drill battery gets really hot when charging, should i be worried?

Accepted Answer

Some warmth is normal, but excessive heat is a problem. First, check the charger's placement. Unplug the charger immediately if the battery is excessively hot. Never place any object on top of the charger. Do not place the charger on a soft surface like a bed or couch. The charger vents through slots in the top and bottom. Blocking these slots causes excessive internal heat. Place the charger on a hard, flat surface away from any heat source. Let the battery cool down to room temperature. The charger has a HOT/COLD DELAY feature and will not charge a battery outside its temperature range. Reinsert the battery and monitor the temperature. If that didn't work, you may be using the wrong battery. Charge only DeWalt 20V Max rechargeable battery packs. Other battery types may overheat and burst. Heads up: Do not operate a charger that has been dropped, received a sharp blow, or is otherwise damaged. Take it to an authorized service center.

Question 11

can i use my dewalt 20v max charger with an extension cord in my garage?

Accepted Answer

Yes, but the extension cord must be rated for outdoor use and have the correct wire gauge to prevent overheating. Use a cord suitable for outdoor use. This reduces the risk of electric shock. Check the ampere rating of your charger (likely 6-10 Amps for 120V). Match it to the cord length:Up to 50 feet: Use 18 AWG minimum. 50 to 100 feet: Use 16 AWG minimum. Over 100 feet: Use 14 AWG or heavier. When disconnecting, pull by the plug, not the cord. IF THAT DIDN'T WORK: Do not place the charger on a soft surface or block its ventilation slots. Ensure the garage location is dry. Do not operate a charger with a damaged cord or plug. HEADS UP: An undersized cord will cause a drop in voltage, resulting in loss of power and overheating of the cord. When in doubt, use a heavier gauge (lower AWG number).

Question 12

my dewalt battery pack gets really hot when charging, is that safe?

Accepted Answer

Some warmth is normal, but excessive heat is a sign of a problem. First, make sure you're giving it a proper place to charge. Place the charger on a hard, flat surface. Never place it on a soft surface like a bed or couch, or put any object on top of it. This blocks the ventilation slots and traps heat. Keep the charger away from any heat source, like a furnace vent or in direct sunlight. Ensure the battery pack is fully seated in the charger. Never force it in. IF THAT DIDN'T WORK: The charger has a hot/cold delay feature. If the battery is outside its ideal temperature range, the charger will delay charging until it's within a safe range. If it's hot to the touch or swelling, stop immediately. Under abusive conditions, liquid can be ejected from the battery, causing irritation or burns. If this happens, flush with water and seek medical help if it contacts eyes. HEADS UP: Only use the charger specified for your DeWalt 20V Max battery. A charger for another type of battery pack may create a risk of fire.

Question 13

my dewalt cordless drill is sparking a little inside near the battery when i put it in, is that normal?

Accepted Answer

Yeah, a small, brief spark when connecting the battery is common and usually harmless. It's just the electrical contact being made. What's not normal is sustained sparking, large sparks, or a burning smell. If you see that, stop immediately. The cause is usually a short circuit. Check the battery terminals and the tool's terminals for debris. Metal shavings, dust, or other conductive material can bridge the contacts. Clean them off with the battery removed. Also, never store a loose battery pack in a drawer with nails, screws, keys, or coins. Those small metal objects can short the terminals, causing burns or a fire. If that didn't work and the tool still sparks abnormally or doesn't run right, the tool or battery is likely damaged internally. Don't use it. Have it serviced by a qualified repair person using only identical replacement parts. Heads up: Always make sure the tool's switch is off before connecting the battery. This prevents accidental starting and can minimize arcing.

Question 14

my dewalt drill keeps stripping screws even on the lowest torque setting, am i doing it wrong?

Accepted Answer

You're likely starting with the torque setting too high. Use the lowest setting to start. Turn the torque adjustment ring to the smallest number. A smaller number means lower torque. Use this setting to drive the screw to the desired depth. It will disengage (click) when it hits the set torque, preventing over-driving. If you need more power, increase the torque setting one click at a time until the screw seats properly without stripping. IF THAT DIDN'T WORK:Check your drill bit/screwdriver bit. A worn or incorrect bit will cam out and strip the screw head. Use sharp, clean bits. Ensure you are using the correct speed. Use Speed 1 (lower speed, higher torque) for driving screws. HEADS UP: Let the tool do the work. Do not force it. Forcing a power tool leads to loss of control, stripped fasteners, and tool damage.

Question 15

can i use an extension cord with my dewalt battery charger? my outlet is far from where i need to charge.

Accepted Answer

Yes, but you need to use the right cord to avoid a fire or shock hazard. An undersized cord will cause a drop in voltage, loss of power, and overheating. First, try to avoid using an extension cord if you can. If you must use one: Only use an extension cord suitable for outdoor use, even if you're indoors. This reduces the risk of electric shock. Check the ampere rating on your charger's nameplate. Match it to this chart for the correct wire gauge (AWG): For a 120V circuit: If your cord is up to 50 feet long, use at least 16 gauge wire. For 100 feet, use at least 14 gauge. The lower the gauge number, the heavier and safer the cord. If in doubt, use the next heavier gauge. Also, make sure the cord is located so it won't be stepped on, tripped over, or damaged. Pull by the plug, not the cord, when disconnecting. Heads up: Never operate the charger if the cord or plug is damaged. Take it to an authorized service center for repair.

Question 16

how do i clean my dewalt drill driver, can i use wd40 or something?

Accepted Answer

You want to avoid solvents like WD-40 on the non-metallic parts, as they can cause damage. Here's the safe way to do it. Disconnect the battery pack from the tool. Use clean, dry compressed air to blow dirt and dust out of all the air vents. Do this at least once a week if you use the tool regularly. Wipe down the exterior with a dry or slightly damp cloth. IF THAT DIDN'T WORK: For heavy grime on metal parts, you can use a mild soap and water solution on a cloth, but make sure no liquid gets inside the tool, especially near the trigger or motor vents. Dry it thoroughly before use. HEADS UP: Always wear ANSI Z87.1 approved safety glasses when blowing out the vents. Never spray liquids directly into the tool or charger. For the charger, unplug it first, and never allow any liquid to get inside—it's a shock hazard.

Question 20

dewalt 20v max drill making a weird clicking noise when i pull the trigger in reverse

Accepted Answer

Yeah, this one's common and it's actually normal. That click is the mechanical brake engaging. The first time you run the tool after changing the direction of rotation using the forward/reverse button, you'll hear a single click on start-up. It's just the internal mechanism and doesn't indicate a problem or damage. It's part of the design to lock the tool off when the control button is in the center position. IF THAT DIDN'T WORK: If the click is continuous, grinding, or happens every single time you pull the trigger (not just the first time after switching directions), that's different. Check that the chuck is tight and there's no debris binding it. If the noise persists, the tool may have internal damage and should be serviced by a qualified repair person using only identical replacement parts.

Question 21

my dewalt cordless drill is making a loud clicking noise when i start it, is it broken?

Accepted Answer

Yeah, this one's common and usually not a problem. That click is the mechanical brake engaging. The first time you run the tool after changing the direction of rotation (using the forward/reverse button), you'll hear a single click on start-up. It's normal. It does not indicate a problem or damage. IF THAT DIDN'T WORK: If the clicking is continuous, rhythmic, or happens during operation (not just at start-up), that's different. Check for a damaged or worn chuck, or debris inside the gear housing. Have it serviced by a qualified repair person. HEADS UP: For regular maintenance, blow dirt and dust out of all air vents with clean, dry air at least once a week. Always wear ANSI Z87.1 approved eye protection when doing this.

Question 22

my dewalt dcd771 drill won't charge at all, the charger light doesn't even come on

Accepted Answer

The charger isn't getting power or is damaged. Check the power source and cord first. Plug the charger directly into a working 120V outlet. Do not use an extension cord unless absolutely necessary. If you must, ensure it's a heavy-gauge outdoor-rated cord. An undersized cord will cause a drop in voltage and overheating. Inspect the charger cord and plug for damage. Do not operate the charger with a damaged cord or plug. Make sure the cord is fully seated in the outlet and the charger. Pull by the plug, not the cord, when disconnecting. IF THAT DIDN'T WORK: The charger itself may have failed. Do not operate the charger if it has been dropped or received a sharp blow. Take it to an authorized DeWalt service center for repair. Do not disassemble it. HEADS UP: Only charge DeWalt 20V Max battery packs with the designated charger. Using another charger creates a risk of fire.
