Drilling in wood or metal
Fig.11
Fig.12
Use the optional drill chuck assembly . When installing it,
refer to "Installing or removing drill bit" described on the
previous page.
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
clockwise to tighten the chuck.
To remove the bit, hold the ring and turn the sleeve
counterclockwise. Set the action mode changing knob to
"rotation only".
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 drill
•
chuck assembly is installed on the tool. The drill
chuck assembly 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.
When performing diamond core drilling operations,
•
always set the change lever to the
use "rotation only" action. If performing diamond
core drilling operations using "rotation with
hammering" action, the diamond core bit may be
damaged.
