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:
If the tool is operated continuously at
low speed for a long time, the motor will get over-
loaded, resulting in tool malfunction.
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.
Set the action mode changing knob to the
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.
