Attention!
The cutters of the diamond dry core bit can be easily damaged beyond repair if they
get stuck in the core drillhole.
► Do not switch off the dry drilling motor until the rotating diamond dry core bit has
been completely removed from the masonry.
The dry drilling motor switches off as soon as the ON / OFF switch (3) is released.

Through-hole:
Caution!
Risk of deformation or fracture!
► Do not hit the diamond dry core bit with hard objects!
If the drill core is stuck in the diamond dry core bit, knock the diamond dry core bit with a
soft piece of wood or plastic to loosen the drill core.
Non through-hole (blind hole):
Caution!
Risk of fracture of the diamond dry core bit's cutting segments and/or damage to the
machine!
► Never use the diamond dry core bit to break out the drill core.
Use a suitable tool, e.g. chisel, TYROLIT chisel hammer (TYROLIT No. 980304) or
TYROLIT breaking out tool to break out the drill core in the stone.
