Drilling with the cradle resting against the drive unit coupled with side load can create enough force to bend the bale or peel the lid off.
Therefore, it is essential to perform the drilling operation without resting the drive cradle against the drive unit, as shown in the picture above.
The drive unit is a pendulum hung attachment designed to swing freely left right, forward and back, which is why, when drilling correctly, the cradle should be positioned up and away from the drive unit allowing the drive and auger bit to swing freely, as shown below.
