6. Confirm the direction of bit rotation
(Fig. 2)
The bit rotates clockwise (viewed from
the rear side) when the reversing
switch lever is set to the "R" side posi-
tion. When the lever is set to the "L"
side position, the bit rotates counter-
clockwise and can be used to loosen
and remove screws.
CAUTION:
Never change the bit rotating direction
while operating the Screw Driver. Turn
the main switch off before changing
the rotating direction, otherwise, burn-
ing of the motor will result.

The tightening depth can be adjusted
by turning locator right and left with
click feeling.
