•	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.
•	A stuck bit can be removed simply by setting the
	reversing switch to reverse rotation in order to back
	out. However, the tool may back out abruptly if you
	do not hold it firmly.
•	Always secure small workpieces in a vise or similar
	hold-down device.
