What must you be prepared for when operating a large drill motor?

When operating a large drill motor, preparation for it potentially kicking is essential. Kicking occurs when the drill bit encounters resistance or binds, which can cause the motor to suddenly jerk or rotate unexpectedly. This reaction is particularly common when drilling into hard materials or when the bit gets stuck. Being aware of this possibility helps the operator maintain control of the tool, ensuring safety and preventing injury. It's crucial for operators to have a firm grip and to stand in a stable position to minimize the risk of being thrown off balance by a kickback.

While overheating, jamming, and excessive vibration are all valid concerns when using a drill, they do not carry the same immediate risk of causing loss of control as kicking does. Understanding how to mitigate these risks, such as maintaining the drill, using the appropriate bit for the material, and ensuring proper technique, is also important but is secondary to the immediate threat posed by the potential for a kick.
