WARNING:
•
Never use “Hammer drilling” when the drill chuck assembly is installed on the
tool. The
drill chuck assembly 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.
