prevent it from slipping away from the hole.
Do not apply more pressure when the hole becomes
clogged with chips or particles. Instead, run the tool at
an idle, then remove the bit partially from the hole. By
repeating this several times, the hole will be cleaned out
and normal drilling may be resumed.
CAUTION:
• There is a tremendous and sudden twisting

break-through, when the hole becomes clogged
with chips and particles, or when striking rein-
forcing rods embedded in the concrete. Always
use the side grip (auxiliary handle) and firmly hold the tool by both side grip and switch handle
during operations. Failure to do so may result
in the loss of control of the tool and potentially
severe injury.
