Hammer drilling operation
CAUTION:
There is a tremendous and sudden twisting force

exerted on the tool/bit at the time of hole break-
through, when the hole becomes clogged with
chips and particles, or when striking reinforcing
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
