CAUTION:
• Never use "rotation with hammering" when the
quick change drill chuck is installed on the tool. The
quick change drill chuck may be damaged.
• Pressing excessively on the tool will not speed up
the drilling. In fact, this excessive pressure will only
serve to damage the tip of your bit, decrease the
tool performance and shorten the service life of the
tool.
• There is a tremendous twisting force exerted on the
tool/bit at the time of hole breakthrough. Hold the
tool firmly and exert care when the bit begins to
break through the workpiece.
• Always secure small workpieces in a vise or similar
hold-down device.
