For reverse (counterclockwise) rotation,
push in the control switch from the left side
of the tool (Fig. 9). 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 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 rotation
before use.

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.

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
Set both the hammer/drill and torque selector
collars to the drill positions.
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.
APPLICATIONS
WARNING
To reduce the risk of electric shock,
check work area for hidden pipes
and wires before drilling or driving
screws.
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 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.
Drilling in Masonry
When drilling in masonry, select the hammer-
drill operating mode (hammer-drills only).
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 drill-
ing 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 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 fi rm pressure before pulling the trig-
ger. Screws can be removed by reversing
the motor.
Overloading
Continuous overloading may cause perma-
nent damage to tool or battery pack.
