The procedure for loosening the chuck only requires that you rotate it in an anticlockwise direction. By applying some pressure, you unroll the chuck till the old Bit can be removed.
  2. Step Two: Take out the Bit: once the Bit is taken out, you would notice that the Bit might be wobbling. Hold the Bit using your fingers and take it out once it’s done. In a scenario where the bits had just been used, avoid using your bare fingers as it would too hot to hold. Use a protective glove to do so.

When the Bit’s smooth portion is placed into the jaws of the chuck, inject the Bit into the chuck and return it towards you. The distance of the pullback shouldn’t be more than a centimeter.
  4. Step Four: Press the Trigger: You will need to give the trigger a few shots to ensure that the Bit is tightened in its appropriate position. You can achieve this by applying a little pressure on the trigger for 2 – 3 seconds. While on this, hold the chuck down with your other hand. This will ensure that the Bit is in position. Another thing to note is that holding it like this ensures that the Bit is correctly installed.

In such a case, what you need to do would be to work on the ratcheting mechanism to ensure the drill bit is firm. It would be best if you twisted the ratcheting to the drill bit’s shank to enable you to come up with this ratcheting mechanism. Once it clicks, you should know that it’s locked in position. Finally, to trigger the ratcheting mechanism, tightly spinning it next to the chuck. This spinning is should be in a clockwise motion.
