Forward/Reverse Control Button (Fig. 2)
A forward/reverse control button (B) determines the direction of the
tool and also serves as a lock-off button.
To select forward rotation, release the trigger switch and depress the
for ward/re verse control button on the right side of the tool.
To select reverse, release the trigger switch and depress the forward/
reverse control button on the left side of the tool.
The center position of the control button locks the tool in the OFF
position. When changing the position of the control button, be sure
the trigger is released.
NOTE: The first time the tool is run after changing the direction of
rotation, you may hear a click on start up. This is normal and does not
indicate a problem.
Worklight (Fig. 2)
There is a worklight (C) located just above the trigger switch (A). The
worklight is activated when the trigger switch is depressed, and will
automatically turn off 20 seconds after the trigger switch is released.
If the trigger switch remains depressed, the worklight will remain on.
NOTE: The worklight is for lighting the immediate work surface and is
not intended to be used as a flashlight.

the drill will not clutch out regardless of the position of the torque

the drill will not clutch out regardless of the position of the torque
