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
position to use
"rotation only" action.
CAUTION:
• If performing diamond core drilling operations
using "rotation with hammering" action, the
diamond core bit may be damaged.
MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection
or maintenance.
• Never use gasoline, benzine, thinner, alcohol or
the like. Discoloration, deformation or cracks may
result.

carbon brush inspection and replacement, any other
