Your tool features a keyless chuck
6
with one rotating chuck
sleeve
15
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.
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.
Worklight (Fig.A)
There is a worklight
5
located just above the trigger switch
1
.
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 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, D–F)
Your tool has an adjustable torque screwdriver mechanism for
driving and removing a wide array of fastener shapes and sizes
and in some models, a hammer mechanism for drilling into
masonry. Circling the torque adjustment collar
3
are numbers,
a drill bit symbol, and on some models, a hammer symbol.
These numbers are used to set the clutch to deliver a torque
range. The higher the number on the collar, the higher the
torque and the larger the fastener which can be driven. To select
any of the numbers, rotate until the desired number aligns with
thearrow.
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.
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.
