DIRECTION-OF-ROTATION 
SELECTOR (FORWARD/CENTER-
LOCK/REVERSE) (FIG. 4) 
FIG. 4
Forward
Reverse
The direction of rotation is reversible and 
is controlled by a selector located above 
the trigger switch. With the Impact Driver 
held in normal operating position: Position 
the direction-of-rotation selector to the left 
of the tool for forward rotation. Postion the 
direction-of-rotation selector to the right 
of the tool for reverse rotation. Setting the 
switch in the OFF (center-lock) position 
helps to reduce the possibility of accidental 
starting when not in use.
NOTICE:  To prevent gear damage, always 
allow the Impact Driver to come to a 
complete stop before changing the direction 
of rotation. 
NOTICE:  The Impact Driver will not run 
unless the direction of the rotation selector 
is engaged fully to the left or right.
ELECTRIC BRAKE
To stop the Impact Driver, release the trig-
ger switch and allow the tool to come to a  
complete stop. The electric brake  
quickly stops rotating. This feature engages  
automatically when you release the trigger 
switch.
