Drill Operation (Fig.E)

WARNING: TO REDUCE THE RISK OF PERSONAL
INJURY, ALWAYS ensure workpiece is anchored or
clamped firmly. If drilling thin material, use a wood
“back‑up” block to prevent damage to thematerial.
1. Turn the collar
10
to the drillsymbol.
2. Select the desired speed/torque range using the gear shifter
to match the speed and torque to the plannedoperation.
3. For WOOD, use twist bits, spade bits, power auger bits or
hole saws. For METAL, use high‑speed steel twist drill bits
or hole saws. Use a cutting lubricant when drilling metals.
The exceptions are cast iron and brass which should be
drilleddry.
4. Always apply pressure in a straight line with the bit. Use
enough pressure to keep drill biting, but do not push hard
enough to stall the motor or deflect thebit.
5. Hold tool firmly with both hands to control the twisting
action of the drill. If model is not equipped with side handle,
grip drill with one hand on the handle and one hand on the
batterypack.
Screwdriver Operation (Fig.D)
1. Select the desired speed/torque range using the dual
range gear selector to match the speed and torque of the
plannedoperation.
2. Turn the torque adjustment collar
10
to the desired
position. Lower numbers indicate lower torque settings;
higher numbers indicate higher torquesettings.
3. Insert the desired fastener accessory into the chuck as you
would any drillbit.
4. Make some practice runs in scrap or on unseen areas to
determine the proper position of the clutchcollar.
5. Always start with lower torque settings, then advance to
higher torque settings to avoid damage to the workpiece
orfastener.

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 disconnect tool from powersource.
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

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/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.
