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:
The dust collection system is
intended for drilling in concrete only. Do not use the
dust collection system for drilling in metal or wood.
CAUTION:
When using the tool with the dust
collection system, be sure to attach the filter
to the dust collection system to prevent dust
inhalation.
CAUTION:
Before using the dust collection
system, check that the filter is not damaged.
Failure to do so may cause dust inhalation.
CAUTION:
The dust collection system col-
lects the generated dust at a considerable rate,
but not all dust can be collected.
NOTICE:
Do not use the dust collection system
for core drilling or chiseling.
NOTICE:
Do not use the dust collection system
for drilling in wet concrete or use this system
in wet environment. Failure to do so may cause
malfunction.
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.
