DIRECTION OF ROTATION SELECTOR
(FORWARD/REVERSE/CENTER LOCK)
See Figure 2, page 8.
The direction of bit rotation is reversible and is controlled
by a selector located above the switch trigger. With the
screwdriver held in normal operating position, the direction
of rotation selector should be positioned to the left of the
switch trigger for forward motion. The direction is reversed
when the selector is to the right of the switch trigger.
Setting the direction of rotation selector in the OFF (center
lock) position helps reduce the possibility of accidental
starting when not in use.
NOTICE:
To prevent gear damage, always allow the collet to
come to a complete stop before changing the direction
of rotation.
To stop the screwdriver, release the switch trigger and allow
the collet to come to a complete stop.
NOTE: The screwdriver will not run unless the direction of
rotation selector is pushed fully to the left or right.
