To remove a drill bit from the Master Mechanic 211897 20-Volt Impact Driver, you typically follow these steps: Release the Chuck: Ensure that the drill is turned off and the battery is removed for safety. Then, grasp the chuck firmly and rotate it counterclockwise to loosen it. This should open the jaws of the chuck. Remove the Drill Bit: Once the chuck is loosened, you can pull out the drill bit from the jaws of the chuck. If the bit is stuck, you may need to wiggle it slightly while pulling to free it from the chuck. Secure the Chuck: After removing the drill bit, rotate the chuck clockwise to tighten it if necessary. Make sure it's securely closed to hold the next drill bit firmly. Insert a New Drill Bit (Optional): If you're replacing the drill bit, insert the new bit into the jaws of the chuck, making sure it's centered and seated properly. Then, tighten the chuck by rotating it clockwise until it's securely closed around the new bit. Test the Chuck: Once the new bit is inserted and the chuck is tightened, give it a gentle tug to ensure it's securely held in place before using the impact driver. Always remember to wear appropriate safety gear, such as safety glasses, when using power tools.
