The distance of the pullback shouldn’t be more than a centimeter.
- 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.
