5. Selecting the appropriate drill bit
䡬
When boring concrete or stone
Use the drill bits specified in the Optional
Accessories.
䡬
When boring metal or plastic
Use an ordinary metalworking drill bit.
䡬
When boring wood
Use an ordinary woodworking drill bit.
However, when drilling 6.5 mm or smaller holes,
use a metalworking drill bit.
6. Confirm the direction of bit rotation (Fig. 6)
The bit rotates clockwise (viewed from the rear
side) by pushing the R-side of the reversing switch
lever. The L-side of the lever is pushed to turn the
bit counterclockwise.

CAUTION
䡬
Never change the direction of bit rotation during
operation.
Turn the power switch OFF before changing the
direction of bit rotation; otherwise, the motor will
burn.
䡬
Always use with clockwise rotation, when using it
as an impact drill.
7. Side handle attachment
Attach the side handle to the mounting part.
Rotate the side handle grip in a clockwise direction
to secure it.
Set the side handle to a position that is suited to
the operation and then securely tighten the side
handle grip.
8. IMPACT to ROTATION changeover (Fig. 7)
The impact drill can be switched from IMPACT
(impact plus rotation) to ROTATION (rotation only)
by simply sliding the change knob. When boring
concrete, stone, tile or similar board materials, slide
the change knob right. The drill head impacts against
the material while continuing to rotate.
When boring metal, wood or plastic, slide the change
knob fully to the left. The drill simply rotates as
an ordinary electric drill.
