Keyless Single Sleeve Chuck (Fig.G–I)

WARNING: Do not attempt to tighten drill bits (or any other
accessory) by gripping the front part of the chuck and turning
the tool on. Damage to the chuck and personal injury may result.
Always lock off trigger switch and remove the battery from the
tool when changingacces sories.

WARNING: Always ensure the bit is secure before starting
the tool. A loose bit may eject from tool causing possible
personalinjury.
Your tool features a keyless chuck
6
with one rotating chuck
sleeve
7
for one-handed operation of the chuck. To insert a drill
bit or other accessory, follow thesesteps.
1. Turn tool off and remove the battery pack.
2. Grasp the black sleeve of the chuck with one hand and
use the other hand to secure the tool. Rotate the sleeve
anticlockwise (as viewed from the front) far enough to accept
the desiredaccessory.
3. Insert the accessory about 19mm into the chuck and tighten
securely by rotating the chuck sleeve clockwise with one hand
while holding the tool with the other hand. Continue to rotate
the chuck sleeve until several ratchet clicks are heard to ensure
full grippingpower.
NOTE: Be sure to tighten chuck with one hand on the chuck
sleeve and one hand holding the tool for maximumtightness.
To release the accessory, repeat steps 1and 2above.
Worklight (Fig.A)
There is a worklight
5
located on the foot of the tool. The
worklight is activated when the trigger switch is depressed.
When the trigger is released, the worklight will stay illuminated
for up to 20seconds.
NOTE: The worklight is for lighting the immediate work surface
and is not intended to be used as aflashlight.
Dual Range Gearing (Fig.A)
The dual range feature of your drill/driver/hammerdrill allows
you to shift gears for greaterversatility.
1. To select speed 1(high torque setting), turn the tool off
and permit it to stop. Slide the gear shifter
4
forward (towards
thechuck).
2. To select speed 2(low torque setting), turn the tool off
and permit it to stop. Slide the gear shifter back (away from
thechuck).
NOTE: Do not change gears when the tool is running. Always
allow the drill to come to a complete stop before changing
gears. If you are having trouble changing gears, make sure that
the dual range gear shifter is either completely pushed forward
or completely pushedback.
Torque Adjustment Collar (Fig.A)
Your tool has an adjustable torque screwdriver mechanism for
Forward/Reverse Control Button (Fig.A)
A forward/reverse control button
2
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 for ward/re verse control button on the right side of
thetool.
To select reverse, release the trigger switch and depress the
forward/reverse control button on the left side of thetool.
The centre 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.
Variable Speed Trigger Switch (Fig.A)
To turn the tool on, squeeze the variable speed
triggerswitch
1
. 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.
NOTE: Continuous use in variable speed range is not
recommended. It may damage the switch and should
beavoided.
Inserting and Removing the Battery Pack from the
Tool (Fig.B)
NOTE: Make sure your battery pack
11
is fullycharged.
To Install the Battery Pack into the Tool Handle
1. Align the battery pack
11
with the rails inside the tool’s
handle (Fig. B).
2. Slide it into the handle until the battery pack is firmly seated
in the tool and ensure that you hear the lock snap intoplace.
To Remove the Battery Pack from the Tool
1. Press the battery release button
12
and firmly pull the
battery pack out of the toolhandle.
2. Insert battery pack into the charger.
Fuel Gauge Battery Packs (Fig.B)
Some DeWALT battery packs include a fuel gauge which
consists of three green LED lights that indicate the level of
charge remaining in the batterypack.
To actuate the fuel gauge, press and hold the fuel gauge
button
14
. A combination of the three green LED lights will
illuminate designating the level of charge left. When the level of
charge in the battery is below the usable limit, the fuel gauge
will not illuminate and the battery will need to berecharged.
NOTE: The fuel gauge is only an indication of the charge left on
the battery pack. It does not indicate tool functionality and is
subject to variation based on product components, temperature
and end-userapplication.
