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.
Also, the drill chuck will come off when reversing
the tool.
• 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.
Diamond core drilling
When performing diamond core drilling operations,
always set the change lever to the
"rotation only" action.
CAUTION:
• If performing diamond core drilling operations
using "rotation with hammering" action, the
diamond core bit may be damaged.
