The torque specifi cations shown here are
approximate values obtained with a fully
charged battery pack.
NOTE: Because the settings shown in the
table are only a guide, use a piece of scrap
material to test the different clutch settings
before driving screws into the workpiece.

Applications
Small screws in soft-
wood.
Medium screws in
softwood or small
screws in hardwood.
Large screws in
softwoods. Medium
screws in hardwood or
large screws in hard-
wood with pilot hole.
Using the Adjustable Clutch
This tool has an adjustable clutch for driving
different types of screws into different materi-
als. When properly adjusted, the clutch will
slip at a preset torque to prevent driving the
screw too deep and to prevent damage to
the screw or tool.
To adjust the clutch, turn the clutch adjusting
ring so that the desired setting (1-23) lines
up with the arrow on the motor housing, as
shown.

Driving
Drilling
Selecting Speed
The speed selector is on top of the motor
housing. Allow the tool to come to a complete
stop before changing speeds. See “Ap-
plications” for recommended speeds under
various conditions.
1. For Low speed (up to 350 RPM), push
the speed selector to the left ("1" is
displayed).
2. For High speed (up to 1400 RPM), push
the speed selector to the right ("2" is
displayed).
Low = 1
High = 2
For reverse (counterclockwise) rotation,
push in the control switch from the left side
of the tool (Fig. 6). Check direction of rota-
tion before use.
Using Control Switch
The control switch may be set to three posi-
tions: forward, reverse and lock. Due to a
lockout mechanism, 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.
For forward (clockwise) rotation, push in the
control switch from the right side of the tool
(Fig. 5). Check the direction of rotation
before use.

APPLICATIONS
To reduce the risk of electric shock,
check work area for hidden pipes
and wires before drilling or driving
screws.
WARNING
To lock the trigger, push the control switch
to the center position (Fig. 7). 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.

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. It will go off when the
trigger is released.
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 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 cut-
ting 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 selector col-
lar 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 trig-
ger. Screws can be removed by reversing
the motor.
Drilling
Set the torque selector collars to the drill
position.
Place the bit on the work surface and ap-
ply 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.
Battery Pack Protection
To protect itself from damage and extend its
life, the battery pack’s intelligent circuit moni-
tors current draw and temperature.
In extremely high torque, binding, stalling,
and short circuit situations, the battery pack
will turn OFF the tool if the current draw be-
comes too high. In these situations, the tool
will "buzz" for about 5 seconds before it turns
OFF. To reset, pull and release the trigger.
If this happens repeatedly, the battery pack
will shut down and need to be placed on the
charger to reset.
Under extreme circumstances, the internal
temperature of the battery could become too
high. If this happens, the battery pack will
shut off. Remove the battery pack from the
tool and place it on the charger to reset it.
Drilling in Wood, Composition Materials
and Plastic
When drilling in wood, composition materials
and plastic, 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.
