chuck adapter (optional accessories).
○ Application of force more than necessary will not only
expedite the work, but will deteriorate the tip edge of the
drill bit and reduce the service life of the rotary hammer
in addition.
○ 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 only function.
○ Do not attempt to use the rotary hammer in the rotation
and striking mode with the drill chuck and chuck adapter
attached. This would seriously shorten the service life of
every component of the machine.
