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.
7. Adjusting the tightening depth
(Fig. 3)
Pull the lock sleeve in the direction of
arrow to remove it from the spline in-
stalled in the gear cover.
While pulling the lock sleeve and turn-
ing it right and left, adjust the position
of locator. Push the lock sleeve and
align the gear cover spline with the lock
sleeve spline.
The lock sleeve can be inserted onto
the gear cover spline and locked.

(2) For drywall screws (Fig. 5)
Mount a drywall screw on the bit, and
