Attempt to Loosen the Chuck
- Use the wrench to grip the body of the chuck firmly.
- Hold the drill steady with one hand, and with the other, turn the chuck counterclockwise to loosen it.
- If the chuck doesn’t budge, gently tap the wrench with a rubber mallet to help break the corrosion bond.
Remove and Clean the Chuck
Once loose, remove the chuck completely. Clean out any debris with a brush and apply a light lubricant before reassembling. Check for damage or wear.
Reassemble and Test
- Reattach the chuck securely onto the drill.
- Insert the battery and test the chuck by tightening and loosening a drill bit to ensure smooth operation.
