OPERATION

Drilling with dust extractor attachment
Fig.20
In drilling operation, hold the tool so that the top end of
the dust extractor attachment is always kept in complete
contact with the surface of concrete.
NOTE:
Any space between them would result in a
•
considerable loss of dust extracting power.
Cleaning out dust bag
Fig.21
Remove the dust bag from the tool. Pull the fastener out
of the dust bag, and then remove dust or particles to
clean out the dust bag.
NOTE:
Too much dust in the dust bag would result in a
•
considerable loss of dust extracting power.
Accordingly, clean out the dust bag from time to
time.
Drilling without dust extractor attachment
Fig.22
This tool can be also used as a standard rotary hammer
without the dust extractor attachment and the dust bag.
Before drilling operation without the dust extractor
attachment and the dust bag, plug the hose port with the
cap provided. The cap reduces the exhaust air from the
dust exhaust port for your comfortable operation.
Hammer drilling operation

Set the action mode changing knob to the
Position the 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 bit partially from the hole. By
repeating this several times, the hole will be cleaned out
and normal drilling may be resumed.
CAUTION:
There is a tremendous and sudden twisting force

exerted on the tool/bit at the time of hole
break-through, when the hole becomes clogged
with chips and particles,
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
operations. Failure to do so may result in the loss
of control of the tool and potentially severe injury.

NOTE:
Eccentricity in the bit rotation may occur while
•
operating the tool with no load. The tool
automatically centers itself during operation. This
does not affect the drilling precision.
Blow-out bulb (optional accessory)

After drilling the hole, use the blow-out bulb to clean the
dust out of the hole.

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.
Drilling in wood or metal

Use the optional drill chuck assembly. When installing it,
refer to "Installing or removing the bit" described on the
previous page.
Set the action mode changing knob to the
You can drill up to 13 mm diameter in metal and up to 32
mm diameter in wood.
CAUTION:
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 bit, decrease the
tool performance and shorten the service life of the
tool.
There is a tremendous twisting force exerted on
•
the tool/bit at the time of hole breakthrough. Hold
the tool firmly and exert care when the bit begins to
break through the workpiece.
A stuck 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 firmly.
Always secure small workpieces in a vise or similar
•
hold-down device.
Diamond core drilling
When performing diamond core drilling operations,
always set the change lever to the
"rotation only" action.
CAUTION:
If performing diamond core drilling operations using
"rotation with hammering" action, the diamond core bit
may be damaged.
