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.
Disposing of dust
Optional accessory
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
symbol.
CAUTION: Always be sure that the tool is
switched off and the battery cartridge is removed
before carrying out any work on the tool.
For HR001G/HR003G
CAUTION: Be sure to wear dust mask when
disposing of dust.
Optional accessory
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.
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”.

For HR002G/HR004G
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.

Use the quick change drill chuck as standard equip-
ment. When installing it, refer to "changing the quick
change chuck for SDS-plus".
Hold the ring and turn the sleeve counterclockwise to
open the chuck jaws. Place the bit in the chuck as far as
it will go. Hold the ring firmly and turn the sleeve clock-

Diamond core drilling
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.
NOTICE: If performing diamond core drilling
operations using “rotation with hammering”
action, the diamond core bit may be damaged.
Blow-out bulb
When performing diamond core drilling opera-
tions, always set the action mode changing knob to
the
position to use "rotation only" action.
Optional accessory
Beating dust on the filter
After drilling the hole, use the blow-out bulb to clean the
dust out of the hole.

Using dust cup set
Optional accessory
CAUTION: Do not turn the dial on the dust
case while the dust case is removed from the
dust collection system. Doing so may cause dust
inhalation.
Fit the dust cup set against the ceiling when operating
the tool.

CAUTION: Always switch off the tool when
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.
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.
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
3 of dust or when you feel the
vacuum performance declined.
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.
