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
Installing drill chuck set
Optional accessory
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. For details on how to install the adapter into
the chuck, refer to the instructions on installing 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.
Beating dust on the filter
Optional accessory
CAUTION:
Do not turn the dial on the dust case
while the dust case is removed from the dust collec-
tion system. Doing so may cause dust inhalation.
CAUTION:
Always switch off the tool when turn-
ing 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-
lecting every 50,000 mm
vacuum performance declined.

Disposing of dust
Optional accessory
CAUTION:
Always be sure that the tool is
switched off and the battery cartridge is removed
before carrying out any work on the tool.
CAUTION:
Be sure to wear dust mask when
disposing of dust.
CAUTION:
Empty the dust case regularly
before the dust case becomes full. Failure to do so
may decrease the dust collection performance and
cause dust inhalation.
CAUTION:
The performance of dust collection
decreases if the filter in the dust case become
clogged. Replace the filter with new one after
approximately 200 times of dust fulfillment as a
guide. Failure to do so may cause dust inhalation.
1. Remove the dust case while pressing down the
latch lever of the dust case.

NOTICE:
When cleaning the filter, tap the case
of the filter gently by hand to remove dust. Do not
tap the filter directly; touch the filter with brush
or similar; or blow compressed air on the filter.
Doing so may damage the filter.
Blow-out bulb
Optional accessory
After drilling the hole, use the blow-out bulb to clean the
dust out of the hole.
► Fig.42
Using dust cup set
Optional accessory
Fit the dust cup set against the ceiling when operating
the tool.
► Fig.43
NOTICE:
Do not use the dust cup set when drill-
ing in metal or similar. It may damage the dust
cup set due to the heat produced by small metal
dust or similar.
NOTICE:
Do not install or remove the dust cup
set with the drill bit installed in the tool. It may
damage the dust cup set and cause dust leak.
