Cleaning Your DEWALT Cordless Drill and Impact Driver
- Use compressed air to blow out dust and debris from vents, motor housing, and around the chuck area.
- Wipe the exterior with a damp microfiber cloth, avoiding excessive moisture near electrical components.
- For stubborn grime, use a mild detergent solution, then dry thoroughly.
- Remove and inspect the drill bits and accessories for wear or damage, replacing as needed.
Inspecting and Maintaining Batteries
- Check the battery contacts for dirt or corrosion; clean with a dry cloth if necessary.
- Ensure batteries are stored in a cool, dry place and avoid extreme temperatures.
- Charge batteries using the official DEWALT charger, avoiding overcharging by removing them once fully charged.
- Periodically perform a capacity test by noting run time to detect degradation.
Lubricating Moving Parts and Chuck
- Apply a few drops of light machine oil to the chuck’s moving parts to maintain smooth bit changes.
- Check the trigger and switch mechanisms—apply lubricant if they feel stiff or sticky, using products recommended for power tools.
- Avoid over-lubricating, as excess oil can attract dirt.
Troubleshooting Common Problems

- Reduced Power or Speed: Clean the contacts and ensure the battery has sufficient charge. Consider replacing worn brushes or worn-out parts.
