If the tool insert becomes caught or jammed,
the drive to the drill spindle is interrupted.
Because of the forces that occur, always hold
the power tool firmly with both hands and
provide for a secure stance.

Removing the Core
GDB 1600 WE with flusing head

: After drilling, con-
tinue to run the water for a short period in order to flush
out the drilling sludge between the core bit and the
core.
If the drilling core is stuck in the core bit, then apply
light blows onto the core bit with a piece of soft wood
or plastic in order to loosen the core. If required, pry the
drilling core out of the core bit using an appropriate
hand tool (slotted screwdriver or similar).
Note:
Do not hammer or apply blows onto the core bit
with hard objects (danger of deformation)!
