The worklight
6
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.
Variable Speed Trigger and Forward/
Reverse Control Button (Fig.A)
The tool is turned on and off by pulling and releasing
the variable speed trigger
3
. The farther the trigger is
depressed, the higher the speed of the tool. Your tool is
equipped with a brake. The chuck will stop as soon as the
trigger switch is fullyreleased.
A forward/reverse control button
4
determines the
rotational direction of the tool and also serves as a
lock‑offbutton.
• To select forward rotation (clockwise), release the trigger
and depress the forward/reverse control button on the
right side of thetool.
• To select reverse (counterclockwise), depress the
forward/reverse control button on the left side of
thetool.
NOTE: 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: Continuous use in variable speed range is not
recommended. It may damage the switch and should
beavoided.
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.
