Set the action mode changing knob to the
symbol.
Hold the tool firmly with both hands. Turn the tool on and
apply slight pressure on the tool so that the tool will not
bounce around, uncontrolled. Pressing very hard on the
tool will not increase the efficiency.

Use the optional drill chuck assembly. When installing it,
refer to "Installing or removing the bit" described on the
previous page.
Set the action mode changing knob so that the pointer
points to the
symbol.
CAUTION:
• Never use "rotation with hammering" when the drill
chuck assembly is installed on the tool. The drill
chuck assembly 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.
MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and the
battery cartridge is removed before attempting to
perform inspection or maintenance.
