Operation; Installing And Removing The Battery Pack; Variable Speed Switch - DeWalt DC727 Instruction Manual

FIG. 2 FIG. 2A
avoid placing the charger or battery pack in a warm environment such
as in a metal shed, or an uninsulated trailer.
CAUTION: Never attempt to open the battery pack for any reason.
If the plastic housing of the battery pack breaks or cracks, return to a
service center for recycling.

OPERATION

Installing and Removing the Battery Pack

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 bat-
tery pack firmly into the handle until you hear the lock snap into place
as shown in Figure 2A.
To remove the battery pack from the tool, press the release buttons
and firmly pull the battery pack out of the tool handle. Insert it into the
charger as described in the charger section of this manual.

Variable Speed Switch

To turn the tool on, squeeze the trigger switch. 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 cen-
terpunch, 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 abra-
sive 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 (Fig. 3)
A forward/reverse control button
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 con-
trol 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 rota-
tion, you may hear a click on start up. This is normal and does not indi-
cate a problem.
Torque Adjustment Collar
(Fig. 4)
The torque adjustment collar (A) is clearly
marked with numbers and a drill bit
symbol.The collar should be rotated until the
desired setting is located at the top of the tool
(Fig. 4). Locators are provided in the collar to
eliminate the guess work when selecting fas-
tening torque. The higher the number on the
collar, the higher the torque and the larger the
fastener which can be driven. To lock the
clutch for drilling operations, move to the drill
bit position.
