Disposing of dust
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.

Close the cover of the dust case, and then attach
the dust case to the dust collection system.
Replacing sealing cap
A damaged or worn-out sealing cap may affect the dust
collecting performance. Replace the sealing cap with
new one as appropriate, aligning its guide projection
with guide notch on the nozzle head.

Storage
NOTICE:
When not in use for a certain period of
time, the nozzle guide needs to be extended to
approximately 100 mm from its fully shortened
position.
Failing to do so may damage the duct hose
pre-installed in the nozzle guide.

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.
NOTICE:
Before using the dust collection sys
-
tem with the tool, read the section about the dust
collection system.
NOTE:
If the battery cartridge is in low temperature,
the tool’s capability may not be fully obtained. In this
case, warm up the battery cartridge by using the
tool with no load for a while to fully obtain the tool’s
capability.

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
symbol.
Position the drill bit at the desired location for the hole,
then pull the switch trigger.
Apply feed force to the switch handle (main handle) for
working accuracy and efficiency, and hold the side grip
(auxiliary handle) to keep balance of the tool.
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.
