CAUTION:

◯Application of force more than necessary will not only reducing drilling effi- ciency at all, but will deteriorate the tip edge of the drill bit and reduce the service life of the rotary hammer in addition.

◯Drill bit 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 main unit in the rotation only function.

◯Do not attempt to use the rotary hammer in the rotation and striking function with the drill chuck and chuck adaptor attached. This would seriously shorten the service life of every components of the machine.
