Position the drill bit at the desired location for the hole,
then pull the switch trigger. Do not force the tool. Light
pressure gives best results. Keep the tool in position
and prevent it from slipping away from the hole.
Do not apply more pressure when the hole becomes
clogged with chips or particles. Instead, run the tool at
an idle, then remove the drill bit partially from the hole.
By repeating this several times, the hole will be cleaned
out and normal drilling may be resumed.
NOTE: Eccentricity in the drill bit rotation may occur
while operating the tool with no load. The tool auto-
matically centers itself during operation. This does not
affect the drilling precision.

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.

Drilling in wood or metal
CAUTION:
Hold the tool firmly and exert care
when the drill bit begins to break through the
workpiece. There is a tremendous force exerted on
the tool/drill bit at the time of hole break through.
CAUTION:
A stuck drill 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.
CAUTION:
Always secure workpieces in a
vise or similar hold-down device.
NOTICE:
Never use "rotation with hammering"
when the drill chuck is installed on the tool. The
drill chuck may be damaged.
Also, the drill chuck will come off when reversing the tool.
NOTICE:
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 drill bit, decrease the
tool performance and shorten the service life of the tool.
Set the action mode changing knob to the
Attach the chuck adapter to a keyless drill chuck to
which 1/2"-20 size screw can be installed, and then
install them to the tool. When installing it, refer to the
section "Installing or removing drill bit".

Diamond core drilling
NOTICE:
If performing diamond core drilling
operations using "rotation with hammering"
action, the diamond core bit may be damaged.
When performing diamond core drilling opera-
tions, always set the action mode changing knob to
the position to use "rotation only" action.

CAUTION:
while the dust case is removed from the dust collec-
tion system. Doing so may cause dust inhalation.
CAUTION:
turning the dial on the dust case. Turning the dial
while the tool is running may result in the loss of
control of the tool.
By beating the dust on the filter inside the dust case,
you can keep the vacuum efficiency and also reduce
the number of times to dispose of the dust.
Turn the dial on the dust case three times after col-
