make exposed metal parts of the power tool "live"
and could give the operator an electric shock.
Safety instructions when using long drill bits with
rotary hammers
1. Always start drilling at low speed and with the
bit tip in contact with the workpiece. At higher
speeds, the bit is likely to bend if allowed to rotate
freely without contacting the workpiece, resulting
