CAUTION
● Application of force more than necessary will not
only expedite the work, but will deteriorate the

● Drill bits may snap off while withdrawing
the rotary hammer from the drilled hole. For
withdrawing, it is important to use a pushing
motion.
● Do not attempt to drill anchor holes or holes in
concrete with the machine set in the rotation
