OPERATION
_WARNING: To reduce the risk of injury, turn unit off
and disconnect it from power source before installing and
removing accessories, before adjusting or when making
repairs. An accidental start-up can cause injury.
Installing and Removing the Battery Pack
(Fig. 3)
NOTE: For best results, make sure FIG.3
your battery pack is fully charged.
To install the battery pack into the
tool handle, align the notch inside
the tool's handle with the battery
pack and slide the battery pack
firmly into the handle until you hear
the lock snap into place as shown
in Figure 2.
To remove the battery pack from the
tool, press the release buttons (I)
and firmly pull the battery pack out
I
of the tool handle. Insert it into the
charger as described in the charger
section of this manual.
Switch - DW059, DWO59H (Fig. 2)
Pressing the BOTTOM part of the rocker switch (B) runs the tool in
forward (right hand thread) direction. Pressing the TOP of the switch
reverses motor direction. This allows "rocking" fasteners to break
them loose.
Variable Speed Trigger Switch (Fig. 2)
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 more you squeeze the trigger, the faster the
tool will operate. Use lower speeds for starting holes without a center
punch, drilling in metals or plastics, or driving screws. 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 (Fig. 2)
A forward/reverse control button (C) 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 forward/reverse control
button on the right side of the tool. To select reverse, 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 (J) located just above the trigger switch (A). The
worklight will be activated when the trigger switch is squeezed.
NOTE: The worklight is for lighting the immediate work surface and
is not intended to be used as a flashlight.
