TRIGGER SWITCH (FIG.2)
To turn the impact driver on, depress the 
trigger switch.
To turn it off, release the trigger switch.
VARIABLE SPEED
The variable-speed trigger switch delivers 
higher speed with increased trigger pressure 
and lower speed with decreased trigger 
pressure.
DIRECTION-OF-ROTATION SE-
LECTOR (FORWARD/CENTER-
LOCK/REVERSE) (FIG.3)
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; position 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 com-
plete stop before changing the direction of 
rotation. 
NOTICE: The impact driver will not run un-
less the direction of the rotation selector is 
engaged fully to the left or right.
MODE SELECTOR (FIG.4)
NOTICE: The impact driver is designed 
with 3-speed and auto-stop functions; 
these functions are available only when the 
tool is operating in forward rotation.
NOTICE: The mode can only be changed 
when the mode-indicator light is on. The 
mode-indicator light will be off automati-
cally in about one minute.
1.  Attach the battery pack to the impact 
driver.
