Set the action mode changing knob to the
symbol.
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.

chuck
Hold the ring and turn the sleeve counterclockwise to
open the chuck jaws. Place the bit in the chuck as far as
it will go. Hold the ring firmly and turn the sleeve clock
-
wise to tighten the chuck. To remove the bit, hold the
ring and turn the sleeve counterclockwise.
Set the action mode changing knob to the
symbol.
You can drill up to 13 mm diameter in metal and up to
32 mm diameter in wood.
CAUTION:
•
Never use "rotation with hammering" when the
quick change drill chuck is installed on the tool.
The quick change drill chuck may be damaged.
Also, the drill chuck will come off when reversing
the tool.
•
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
position to use
"rotation only" action.
CAUTION:
•
If performing diamond core drilling operations
using "rotation with hammering" action, the
diamond core bit may be damaged.
Operation when using the dust cup
(accessory)
►

Dust cap
Operate the tool with the dust cup against the ceiling
surface.
NOTE:
•
The dust cup (accessory) is intended only for
drilling in the ceramic workpiece such as con-
crete and mortar. Do not use the tool with the
dust cup when drilling in metal or similar. Using
the dust cup for drilling in the metal may dam-
age the dust cup due to the heat produced by
small metal dust or similar.
•
Empty the dust cup before removing a drill bit.
•
When using the dust cup, make sure that the
dust cap is mounted on it securely.
