OPERATION
CAUTION: Always use the side grip (auxiliary
handle) and rmly 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 lter
to the dust collection system to prevent dust
inhalation.
CAUTION: Before using the dust collection
system, check that the lter 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.

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 rmly 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.

18 ENGLISH
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. 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 symbol.
Holdthetoolrmly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efciency.
►Fig.34
Drilling in wood or metal
CAUTION: Hold the tool rmly and exert care
when the drill bit begins to break through the
workpiece. There is a tremendous force exerted on
the tool/drill bit at the time of hole break through.
CAUTION: A stuck drill bit can be removed
simply by setting the reversing switch to reverse
rotation in order to back out. However, the tool
may back out abruptly if you do not hold it rmly.
CAUTION: Always secure workpieces in a
vise or similar hold-down device.
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.
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.
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”.
