CAUTION:

0 Pressing excessively on the tool will not speed up the drilling. In fact, this excessive pres- sure 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 force exerted on the tool/bit a t the time of hole breakthrough. Hold the tool firmly and exert care when the bit begins to break through the workpiece.

0 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 hole it firmly.

.Always secure small workpieces in a vise or similar hold-down device.
