APPLICATIONS
WARNING To reduce the risk of electric
shock, check work area for hidden pipes and
wires before drilling or driving screws.

ferent clutch positions before driving screws into
the workpiece.

NOTE: The number selected on the torque collar
has no effect on operation of the drill in drilling
mode.
3. To use the driving screws mode rotate the
application selector collar until the drive symbol
appears in line with the arrow. Then rotate
the torque selector collar until the desired clutch
setting appears in line with the arrow.
The adjustable clutch, when properly adjusted, will
slip at a preset torque to prevent driving the screw
too deep into different materials and to prevent
damage to the screw or tool.
The torque specifi cations shown here are ap-
proximate values.
Starting, Stopping and Controlling Speed
1. To start the tool, grasp the handle fi rmly and
pull the trigger.
NOTE: An LED is turned on when the trigger
is pulled.
2. To vary the speed, increase or decrease the
pressure on the trigger. The further the trigger
is pulled, the greater the speed.
3. To stop the tool, release the trigger. Make sure
the bit comes to a complete stop before laying
the tool down.
Drilling
Place the bit on the work surface and apply fi rm
pressure before starting. Too much pressure will
slow the bit and reduce drilling effi ciency. 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.
Using Control Switch
The control switch may be set to three positions:
forward, reverse and lock. Due to a lockout mecha-
nism, the control switch can only be adjusted when
the ON/OFF switch is not pressed. Always allow
the motor to come to a complete stop before using
the control switch.
Drilling in Wood, Composition Materials and
Plastic
When drilling in wood, composition materials and
plastic, select the
drill-only operating mode.
Start the drill slowly, gradually 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 fl utes. To reduce the
chance of splintering, 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, select the
drill-only
operating mode. 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 nonfer-
rous metals such as copper, brass or aluminum.
Back the material to prevent binding and distortion
on breakthrough.
Drilling in Masonry
When drilling in masonry, select the hammer-
drill operating mode. Use high speed carbide-tipped
bits. Drilling soft masonry materials such as cinder
block requires little pressure. Hard materials like
concrete require more pressure. A smooth, even
fl ow of dust indicates the proper drilling rate. Do not
let the bit spin in the hole without cutting. Do not
use water to settle dust or to cool bit. Both actions
will damage the carbide.
Driving Screws and Nut Running
Drill a pilot hole when driving screws into thick or
hard materials. Select the
driving screws mode.
Set the torque selector 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 fi rm
pressure before pulling the trigger. Screws can be
removed by reversing the motor.
Overloading
Continuous overloading may cause permanent
damage to tool or battery pack.
WARNING High rotational force. To
reduce the risk of injury, always hold or brace
securely. Always use side handle on tools.

For forward (clockwise) rotation, push in the control
switch from the right side of the tool. Check the
direction of rotation before use.
For reverse (counterclockwise) rotation, push in the
control switch from the left side of the tool. Check
direction of rotation before use.
To lock the trigger, push the control switch to the
center position. 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
accessories, storing the tool and any time the tool
is not in use.
NOTE: When using carbide bits, do not use wa-
ter to settle dust. Do not attempt to drill through
steel reinforcing rods. This will damage the
carbide bits.
2. To use the drilling only mode, rotate the ap-
plication selector collar until the drill symbol
appears in line with the arrow.

To Drill
WARNING To reduce the risk of injury,
always use a side handle when using this tool.
Always brace or hold securely. Ensure side
handle is tightened securely before each use.
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.
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 specifi c purposes.
• Use caution when drilling pitchy, knotty, wet or
warped material or when drilling in material that
may contain nails.
