Bit Binding
A high rotational force occurs when a bit
binds. If the bit binds, the tool will be forced
in the opposite direction of the bit rotation.
Bits may bind if they are misaligned or when
they are breaking through a hole. Wood
boring bits can also bind if they run into
nails or knots. Be prepared for bit binding
situations.
WARNING!
High rotational force. To reduce
the risk of injury, always hold or
brace securely.
To reduce the chance of bit binding:
Use sharp bits. Sharp bits are less
likely to bind when drilling.
Use the proper bit for the job. There
are bits that are designed for specific
purposes.
Use caution when drilling pitchy,
knotty, wet or warped material or
when drilling in material that may con-
tain nails, screws, staples, etc.
APPLICATIONS
Drilling in Wood, Composition Materi-
als and Plastic
When drilling in wood, composition materi-
als and plastic, start the drill slowly, gradu-
ally increasing speed as you drill. When
drilling into wood, use wood augers or
twist drill bits. Always use sharp bits.
When using twist drill bits, pull the bit out of
the hole frequently to clear chips from the
bit flutes. To reduce the chance of splin-
tering, back work with a piece of scrap
wood. Select low speeds for plastics with
a low melting point.
Drilling in Metal
When drilling in metal, use high speed steel
twist drills or hole saws. Use a center
punch to start the hole. Lubricate drill bits
with cutting oil when drilling in iron or steel.
Use a coolant when drilling in nonferrous
metals such as copper, brass or aluminum.
Back the material to prevent binding and
distortion on breakthrough.
Driving Screws and Nut Running
Drill a pilot hole when driving screws into
thick or hard materials. Set the torque se-
lector collar to the proper position and set
the speed to low. Use the proper style and
size screwdriver bit for the type of screw
you are using.
With the screwdriver bit in the screw, place
the tip of the screw on the workpiece and
apply firm pressure before pulling the trig-
ger. Screws can be removed by reversing
the motor.
WARNING!
To reduce the risk of electric
shock, check work area for hidden
pipes and wires before drilling or
driving screws.
Overloading
Continuous overloading may cause per-
manent damage to tool or battery pack.
For
reverse
(counterclockwise) rotation,
push in the control switch from the left
side of the tool (Fig. 9).
Check direction
of rotation before use.
Selecting Speed (Fig. 7)
Using Control Switch (Fig. 8, 9 and 10)
The control switch may be set to three
positions: forward, reverse and lock. Due
to a lockout mechanism, the control switch
can only be adjusted when the ON/OFF
switch is not depressed. Always allow the
motor to come to a complete stop before
using the control switch.
For
forward
(clockwise) rotation, push in
the control switch from the right side of the
tool (Fig. 8).
Check the direction of rota-
tion before use.

High
Low
The speed selector is on top of the motor
housing. Allow the tool to come to a com-
plete stop before changing speeds. See
Applications for recommended speeds
under various conditions.
1. For
Low
speed (up to 400 RPM), push
the speed selector back, displaying the
"1" for low.
2. For
High
speed (up to 1400 RPM), push
the speed selector forward, display-
ing the "2" for high.

To
lock
the trigger,
push the control switch
to the center position (Fig. 10). The trigger
will not work while the control switch is in
the center locked position. Always lock the
trigger or remove the battery pack before
performing maintenance, changing acces-
sories, storing the tool and any time the
tool is not in use.
Push in
for forward
Push in
for reverse
Starting, Stopping & Controlling
Speed
1. To
start
the tool, pull the trigger.
2. To
stop
the tool, release the trigger
and an electric brake stops the tool
instantly.
All models feature variable speed control.
To vary the speed, increase or decrease
pressure on the trigger. The further the
trigger is pulled, the greater the speed.
Drilling
Set the torque selector collar to the drill
position
Place the bit on the work surface and ap-
ply firm pressure before starting. Too much
pressure will slow the bit and reduce drill-
ing efficiency. Too little pressure will cause
the bit to slide over the work area and dull
the point of the bit.
If the tool begins to stall, reduce pressure
slightly to allow the bit to regain speed. If
the bit binds, reverse the motor to free the
bit from the workpiece.
