Installing and Removing the Battery
Pack (Fig. 2, 3)
NOTE: Make sure your battery pack is fully charged.
To install the battery pack into the tool handle, align the base of
the tool with the notch inside the tool's handle (Fig. 2) and slide the
battery pack firmly into the handle until you hear the lock snap into
place. To remove the battery pack from the tool, press the release
buttons and firmly pull the battery pack out of the tool handle
as shown in Fig. 3. Insert it into the charger as described in the
charger section of this manual.
Variable Speed Switch (Fig. 4)
To turn the tool on, squeeze the trigger switch (A). To turn the tool
off, release the trigger switch. Your tool is equipped with a brake.
The chuck will stop as soon as the trigger switch is fully released.
The variable speed switch enables you to select the best speed
for a particular application. The farther you squeeze the trigger,
the faster the tool will operate. Use lower speeds for starting holes
without a centerpunch, drilling in metals or plastics, driving screws

and drilling ceramics, or in any application requiring high torque.
Higher speeds are better for drilling in wood, wood compositions
and for using abrasive and polishing accessories. For maximum
tool life, use variable speed only for starting holes or fasteners.
NOTE: Continuous use in variable speed range is not recommended.
It may damage the switch and should be avoided.

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.
