OPERATION
INSTALLING/REMOVING BITS
See Figures 4 - 5, page 10.
The arrows on the keyless chuck indicate which direction
to rotate the chuck sleeve to tighten or release the drill bit.
Do not use a wrench to tighten or loosen the chuck jaws.
 To install bits, lock the switch trigger.
 Open or close the chuck jaws until the opening is slightly
larger than the bit size you intend to use.
 Raise the front of the drill slightly and insert the drill bit.
WARNING:
Make sure to insert the drill bit straight into the
chuck jaws. Do not insert the drill bit into the chuck
jaws at an angle, then tighten. This could cause
the drill bit to be thrown from the drill, resulting in
possible serious personal injury or damage to the
chuck.
 Rotate the chuck sleeve to close and tighten the chuck
jaws.
WARNING:
Do not hold the chuck sleeve with one hand and
use the power of the drill to tighten the chuck jaws
on the drill bit. The chuck sleeve could slip in your
hand, or your hand could slip and come in contact
with the rotating drill bit. This could cause an acci-
dent resulting in serious personal injury.
 To remove bits, lock the switch trigger and open the
chuck jaws.
 The bit provided with the drill can be placed in the storage
area, located on the rear base of the drill.
TWO-SPEED GEAR TRAIN
See Figure 6, page 10.
 Select low speed (1) speed for applications requiring
higher power and torque.
 Select high speed (2) speed for fast drilling or driving
applications.
NOTICE:
Never change speeds while the tool is running.
Failure to obey this caution could result in serious
damage to the drill.
NOTE: If you have difficulty changing from one speed range
to the other, turn the chuck by hand until the gears engage.
ADJUSTING TORQUE
See Figure 7, page 10.
Rotate the adjustment ring to the proper torque setting for
the type of material and size of screw you are using.
• 1 - 4 For driving small screws
• 5 - 8 For driving screws into soft material
• 9 - 12 For driving screws into soft and hard
materials
• 13 - 16 For driving screws into hard wood
• 17 - 23 For driving large screws
• For heavy drilling
LED LIGHT
See Figure 8, page 10.
The LED light, located on the front of the tool base, illumi-
nates when the switch trigger is depressed.
If the drill is not in use, the time-out feature will cause the
light to start fading and then shut off.
The LED light illuminates only when there is a charged bat-
tery pack in the tool.
DRILLING/DRIVING SCREWS
See Figure 9, page 10.
 Check the direction of rotation selector for the correct
setting (forward or reverse).
 Select low speed (1) or high speed (2), depending on
your application. Refer to Two-Speed Gear Train and
Adjusting Torque.
 Secure the workpiece in a vise or with clamps to keep it
from turning as the bit rotates.
 Hold the drill firmly and place the bit at the point to be
drilled, or where the screw is to be driven.
WARNING:
Do not drive a screw where there is likely to be
hidden wiring behind the surface. Contact with a
"live" wire will make exposed metal parts of the tool
"live" and possibly shock the operator. If you must
drive a screw where hidden wire may be present,
always hold tool by insulated gripping surfaces
(handle) when performing the operation to prevent
a shock to the operator.
 Depress the switch trigger to start the drill.
 Move the bit into the workpiece, applying only enough
pressure to keep the bit cutting or driving the screw. Do
not force the drill or apply side pressure to elongate a
hole. Let the tool do the work.
