Disposing of dust
CAUTION:
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
then cause dust inhalation.
CAUTION:
Replace the filter with new one
after approximately 200 times of dust fulfillment
as a guide. A clogged filter decreases dust collection
performance, and then cause dust inhalation.
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.
1.
Remove the dust case while pressing down the
lever of the dust case.

ing of dust.)
2.
Open the filter cover of the dust case.

4. Attach a new filter to the filter case, and then
attach the filter cover.
5. Close the cover of the dust case, and then attach
the dust case to the dust collection system.
Replacing sealing cap
If the sealing cap is worn out, the performance of the
dust collection decreases. Replace it if it is worn out.
Remove the sealing cap, and then attach a new one
with its protrusion facing upward.

OPERATION

CAUTION:
Always use the side grip (auxiliary
handle) and firmly hold the tool by both side grip
and switch handle during operations.
CAUTION:
Always make sure that the work-
piece is secured before operation.
CAUTION:
Do not pull the tool out forcibly
even the bit gets stuck. Loss of control may
cause injury.
CAUTION:
For HR3011FC, HR3012FC only
Before using the dust collection system with the
tool, read the section about the dust collection
system.

Hammer drilling operation
CAUTION:
There is tremendous and sudden
twisting force exerted on the tool/drill bit at the time of
hole break-through, when the hole becomes clogged
with chips and particles, or when striking reinforcing
rods embedded in the concrete. Always use the side
grip (auxiliary handle) and firmly hold the tool by
both side grip and switch handle during opera-
tions. Failure to do so may result in the loss of control
of the tool and potentially severe injury.
Set the action mode changing knob to the
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.
Chipping/Scaling/Demolition
Set the action mode changing knob to the
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.
