occur when a Core bit gets stuck. Maintain a firm grip, in order not to drop the machine, too. Use extra care when you are
on ladders, roofs, scaffolds, …etc.

When drilling through floors, the core will be likely to fall down from inside of the Core-Bit. Under these circumstances,
provide proper protections for people and property below the coring area. For example, fencing around the particular area
down floor, making the place “KEEP OFF” …etc.
