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 switch
3
. The farther the trigger
switch 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
switch 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.

2. Grasp the black sleeve of the chuck with one hand
and use the other hand to secure the tool. Rotate the
sleeve counterclockwise far enough to accept the
desiredaccessory.

and tighten securely by grasping and rotating
the chuck sleeve
7
clockwise with one hand while
holding the tool with the other. When the chuck is
nearly tightened you will hear a clicking sound. Continue
tightening as far as you can. Your tool is equipped with
an automatic spindle lock mechanism. This allows you to
open and close the chuck with onehand.

chuck sleeve and one hand holding the tool for
maximum tightness. When tightening, do not turn in the
counterclockwisedirection.
