Using Control Switch
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.
Check the direction of rotation
before use.

Starting, Stopping and Controlling
Speed
1. To
start
the tool, grasp the handle fi rmly
and pull the trigger.
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
firm 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.
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.

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.
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.
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. 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 perma-
nent damage to tool or battery pack.
APPLICATIONS
To reduce the risk of electric shock,
check work area for hidden pipes
and wires before drilling or driving
screws.
