TORQUE-ADJUSTMENT RING
See Fig. 6
Your tool features 25+1 clutch settings. Output
torque will increase as the torque-adjustment ring is
rotated from 1 to 25. The drill “
” position will
lock the clutch to permit drilling and driving for
heavy-duty work.
When using the drill / driver for different driving
applications, increase or decrease the torque in
order to help prevent damaging screw heads,
threads, workpiece, etc.
The proper setting depends on the job and the type
of bit, fastener, and material you will be using. In
general, use greater torque for larger screws. If the
torque is too high, the screws may be damaged or
broken. For delicate operations, such as removing a
partially stripped screw, use a low torque setting.
For operations such as drilling into hardwood, use a
higher torque setting.
NOTICE: Do not adjust the torque when the tool is
running.
LED WORKLIGHT
Your tool is equipped with an LED worklight,
located in the front of the tool, that illuminates
when the variable-speed trigger switch is
squeezed. This provides additional light on the
surface of the workpiece for operation in lower-
light areas.
INSTALL AND REMOVE BITS
See Fig. 7
Do not use the power of the drill while
grasping chuck to loosen or tighten the chuck
jaws on the bit. Friction burns or hand injury is
possible if attempting to grasp the spinning
chuck.
Do not use bits with damaged shanks.
Your tool is equipped with a keyless chuck to
tighten or release bits in the chuck jaws. The
arrows on the chuck indicate the direction in which
to rotate the chuck body in order to LOCK (tighten)
or UNLOCK (release) the chuck jaws on the bit.
d.
Lock the variable-speed trigger switch “OFF” on
the tool by placing the direction-of-rotation
selector in the center position.
e.
Remove the battery pack and select the Drill
Position.
To install the bit
a.
Grasp the rear half of the chuck with one hand
and use your other hand to rotate the front half
in the counterclockwise direction, as viewed
from chuck end, to open the chuck to
approximately the bit diameter.
b.
Insert a clean bit up to the drill-bit flutes for
small bits, or as far as it will go for large bits.
Tighten securely by holding the rear half of the
chuck and rotating the front portion in the
clockwise direction as viewed from the chuck
end.
To remove the bit
a.
Grasp the rear half of the chuck with one hand
and use your other hand to rotate the front half
in the counterclockwise direction, as viewed
from chuck end, to open the chuck.
b.
Remove the bit.
Use protective gloves when
removing the bit from the tool, or
first allow the bit to cool down. The bit may be hot
after prolonged use.
DRILL BITS
Always inspect drill bits for excessive wear. Use only
bits that are sharp and in good condition.
Twist Bits: Available with straight and reduced
shanks for wood and light-duty metal drilling. High-
speed bits cut faster and last longer on hard
materials.
Carbide-Tipped Bits: Used for drilling stone,
concrete, plaster, cement, and other unusually hard
nonmetal materials. Use continuous, heavy feed
pressure when using carbide-tipped bits.
DRILLING
See Fig. 8
Always wear safety goggles or
safety glasses with side shields
during power tool operation or when blowing dust.
If operation is dusty, also wear a dust mask.
a. Check that the direction-of-rotation selector is at
the correct setting (forward or reverse).
b. Secure the material to be drilled in a vise or with
clamps to keep it from turning as the drill bit
rotates.
c. Hold the drill firmly, and place the bit at the point
to be drilled.
d. Depress the variable-speed trigger switch to start
the drill.
e. Move the drill bit into the workpiece, applying
only enough pressure to keep the bit “biting”. Do
not force the drill or apply side pressure to
elongate a hole. Let the tool do the work.
f. When drilling hard, smooth surfaces, use a center
punch to mark the desired location of the hole.
This will prevent the drill bit from slipping off-
center as the hole is started.
g. When drilling metals, use light oil on the drill bit
to keep it from overheating. The oil will prolong
the life of the bit and increase the drilling action.
h. If the bit jams in the workpiece or if the drill
stalls, stop the tool immediately. Remove the bit
from the workpiece and determine the reason
for jamming.
NOTICE: There are two rules for drilling hard
materials. First, the harder the material, the greater
the pressure you need to apply to the tool. Second,
the harder the material, the slower the speed
should be. If the hole to be drilled is fairly large, drill
