Drill Operation (Fig.A)

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. Select the desired speed/torque range using the
gear shifter
8
to match the speed and torque to the
plannedoperation.
2. 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.
3. Always apply pressure in a straight line with the bit. Use
enough pressure to keep the drill bit biting, but do not push
hard enough to stall the motor or deflect thebit.
Screwdriver Operation (Fig.A)
1. Select the desired speed/torque range using the
three-speed gear shifter
8
on the top of the tool. If using
the torque adjustment collar
5
, initially set the three-speed
gear shifter to speed 2or 3. This ensures effective control
over the fastener allowing the screw to be seated correctly
and set to specification. Speed 1will provide the same
clutching torque as speeds 2and 3. However, for optimum
performance of the electronic clutch, speeds 2and
3arepreferred.
NOTE: Use the lowest torque setting (1) first and increase
the number through to the highest setting (11) to seat the
fastener at the desired depth. The lower the number, the
lower the torqueoutput.
2. Reset the torque adjustment collar
5
to the appropriate
number setting for the torque desired. Make a few practice
runs in scrap or unseen areas to determine the proper
position of the torque adjustmentcollar.
NOTE: The torque adjustment collar may be set to any number
at anytime.
Proper Hand Position (Fig. D)

WARNING: To reduce the risk of serious personal injury,
ALWAYS use proper hand position as shown.

WARNING: To reduce the risk of serious personal injury,
ALWAYS hold securely in anticipation of a suddenreaction.
Proper hand position requires one hand on the main
handle 
15
, with the other hand on the side handle
14
to
control the twisting action of thedrill.
OPERATION
Instructions for Use

WARNING: Always observe the safety instructions and
applicableregulations.

WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect battery pack
before making any adjustments or removing/
installing attachments or accessories. An accidental
start‑up can causeinjury.
Keyless Single Sleeve Chuck (Fig.C)

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.
Spotlight Mode
The high setting is the spotlight mode. The spotlight will run
for 20minutes after the trigger switch is released. Two minutes
before the spotlight will shut off, it will flash twice and then dim.
To avoid the spotlight shutting off, lightly tap the triggerswitch.

WARNING: While using the worklight in medium or
spotlight mode, do not stare at the light or place the drill in
a position which may cause anyone to stare into the light.
Serious eye injury couldresult.

CAUTION: When using the tool as a spotlight, be sure
it is secured on a stable surface where it will not cause a
tripping or fallinghazard.

CAUTION: Remove all accessories from the chuck before
using the drill as a spotlight. Personal injury or property
damage couldresult.
Low Battery Warning
When in spotlight mode and the battery is nearing complete
discharge, the spotlight will flash twice and then dim. After two
minutes, the battery will be completely discharged and the
drill will immediately shut down. At this point, replace with a
chargedbattery.

WARNING: To reduce the risk of injury, always have a
back‑up battery or secondary lighting available if the
situation warrantsit.
